Item Open Access Stress reduction therapy in immersive environments : does rotation mode have an effect on mental stress?(2024) Feng, YumingMental stress, exacerbated by various contemporary factors including the COVID-19 pandemic, rapid technological advancements, and global crises, poses significant challenges. Immersive technologies like virtual reality (VR) offer promising avenues for stress relief. This paper explores the efficacy of VR immersion, particularly the impact of rotational motion, in mitigating mental stress. Through heart rate monitoring, it investigates the intricate interplay between immersive VR environments and stress reduction. Integrating insights from VR therapy, meditation practices, and heart rate analysis, the study contributes to the burgeoning field of mental health technology. It proposes VR as a novel tool for stress management, providing multisensory meditation experiences. The study also explores the use of innovative hardware like the NOVA Ball to induce immersive meditative states. The experimental design seeks to understand VR’s therapeutic potential for stress reduction, bridging the gap between technological innovation and practical mental health solutions. Research Background and Purpose: This study systematically evaluates user experiences in a VR environment integrating physiological data, focusing on the influence of physical rotation elements. It uncovers correlations between heart rate variations, physical rotation, and user experiences, informing future VR design. By delving into the relationship between heart rate fluctuations and participants’ emotional and cognitive states under physical rotation conditions, the study deepens understanding of rotation actions’ mental health effects in VR. Additionally, it assesses VR’s potential as a mental health intervention, particularly in stress reduction, by merging subjective experience questionnaires with objective physiological heart rate data. This holistic approach enriches VR’s role in mental health and guides future developments in user experience design and VR therapy applications.Item Open Access Exploring indigenous knowledge in VR design: Incorporating kaupapa Māori to increase engagement when collaborating with a virtual agent.(2024) McNeill, Hēmi AteremuThis thesis explores the integration of kaupapa Māori principles into Virtual Reality (VR) environments, focusing on collaboration with virtual agents within Human Computer Interaction (HCI) research. Kaupapa Māori, as an indigenous knowledge system, and kaupapa Māori research, as an indigenous methodology, offer a cultural lens through which the design and implementation of VR technologies can enhance user engagement, foster inclusive design, and address the grand challenges in HCI identified by Stephanidis et al. (2019). The research is motivated by a gap in existing literature regarding the effects of incorporating kaupapa Māori into the design of Virtual Reality (VR) environments with collaborative virtual agents. Through a qualitative user study, this thesis investigates how kaupapa Māori interventions influence engagement with a virtual agent, and assesses the implications for inclusive design from a kaupapa Māori perspective. The study was structured around three primary research aims: 1) to investigate kaupapa Māori interventions in VR, 2) to use these interventions to prime engagement when collaborating with a virtual agent, and 3) to contribute to inclusive design principles informed by kaupapa Māori. Key findings reveal that kaupapa Māori interventions, particularly those inspired by pōwhiri (the Māori welcoming ceremony) and whakapapa (genealogy), can impact users’ sense of welcome and connection, and encourage engagement within the virtual environment. While the interventions aimed at priming engagement presented subtle effects, they underscored the complexity of designing meaningful interaction in VR. Furthermore, the study highlights the critical role of cultural perspectives and practices, as provided through wānanga, in the development of culturally informed inclusive design. The research contributes to Human Computer Interaction (HCI) by demonstrating the potential of indigenous knowledge systems to enrich digital environments, providing novel insights into influencing user engagement and motivation, and expanding the discourse on culturally informed technology design. This thesis advocates for the inclusion of kaupapa Māori and other indigenous epistemologies in the broader field of HCI, suggesting that such integration not only addresses current challenges within the discipline but also paves the way for more accessible, equitable, and culturally resonant technological innovations.Item Open Access Investigate on how a simulated Cognitive Augmentation to detect deception, impact decision making confidence in negotiations(2024) Seneviratne, AmaliThis thesis explores the simulated integration of cognitive augmentation (CA) and augmented reality (AR) in deception detection within negotiation contexts. It assesses how AR visualizations of deception probabilities impact decision-making confidence and user acceptance. The study reveals that while visualization methods alone do not significantly alter confidence levels, a strong positive correlation exists between users' comfort with CA technologies and their decision-making confidence. This underscores the importance of user-centric design and familiarity with technology for effective CA implementations. The research also addresses public perceptions and ethical considerations, suggesting cautious optimism toward these technologies in high-stakes environments. Recommendations include enhancing algorithm accuracy, technical transparency, expanding interface designs, and developing ethical frameworks to support technology adoption.Item Open Access Utilizing augmented reality for attention guidance in outdoor cultural heritage storytelling.(2024) Ren, RenCultural heritage institutions have a tradition of storytelling. Storytelling is often conducted through audio guides that require visitors to pay attention to details that are essential for understanding the cultural and historical significance of cultural heritage. However, guiding attention to these details using solely audio can be challenging. While various modalities such as physical, auditory, tactile and social have been explored, they each present limitations, particularly in the complex environment of outdoor cultural heritage sites. This study explores an alternative method, specifically Augmented Reality (AR), to address these limitations. Through a user study conducted at the Kate Sheppard House involving 30 participants, and employing a within-subjects design, we compared two AR guidance techniques (Virtual Arrow and Green Laser) against the traditional Audio Only in terms of response time, knowledge retention and user preference. The study results indicate that, although there was no statistical difference in the objective data, trends suggest a potential advantage of AR in enhancing visitors’ attention. By integrating subjective feedback with observations, we offer implications for designers of outdoor cultural heritage sites and suggest directions for future research.Item Open Access A study on audience experience of diegetic portals as a scene transition device in cinematic virtual reality.(2024) Adams, EleanorThis thesis seeks to explore the use of portals applied in cinematic virtual reality (CVR) as a scene transition method, and to outline some key characteristics of a portal in this context. A 15 minute CVR prototype experience featuring portal transitions, triggered through interactions with a portkey object was developed in the Unity game engine. A user study was conducted with this prototype with the aim to qualitatively uncover dominant subjective perspectives of the portal transition in the CVR context. Two dominant social perspectives, that were termed Voyagers and Observers emerged from this sample. The two perspectives are distinct collective viewpoints, and each participant was sorted into one of these groups depending on the answers they gave in the user study. There was distinguishing opinions between the two collective groups, but also some opinions that were similar between both groups. The interpreted results provide a flexible best practice guideline, with four design principles for portal transitions in CVR narratives. This may be utilised by future directors and content producers of CVR experiences, as well as providing insight for researchers in the field of interactive digital narratives, and cinematic virtual reality.Item Open Access The sense of copresence in a job interview environment supported by an augmented reality device.(2024) Figueroa , FelipeWithin an organization, personnel recruitment is a critical activity in the human resources strategy. Job interviews are considered one of the most widely used recruitment methods; however, the evolution that this type of method has undergone over time, especially with the use of new technology, has drawn the attention of researchers in the field of human interface technology. One of the disadvantages of e-recruitment, as the new technological tools of the recruitment process are known, is the negative reactions that the use of technological tools generates in the interviewees. Augmented reality (AR) has stood out for its use in the industrial and health fields thanks to the display of virtual information in the real world. If we think that the use of this tool could be massified to other work contexts, such as personnel selection, and on the other hand, we take into account the adverse responses that this technology could have on the interviewees, the study of these responses is then relevant. In order to know these responses, exploratory and experimental research has been conducted, grouping the participants in two contexts: one under conditions of interaction with AR technology and the other without such support. The results of this research show the ability of participants to perceptually isolate a possibly new stimulus (the AR headset) and focus their attention on the interview questions. On the other hand, the importance of the quality of the sustained rapport between interviewer and interviewee is also evidenced as an element that eliminates the theoretical barrier that the use of an augmented reality device could mean.Item Open Access Teaching dance with mixed reality mirrors : comparing virtual instructors to other forms of visual feedback.(2024) Treffer, AnnaThis research aimed to assess whether a virtual instructor and visual feedback combination displayed on a Mixed Reality (MR) mirror can be used to teach a beginner a simple dance routine, replacing the traditional instructor and mirror methods. A prototype was developed using a camera and projector that displayed a digital mirror image of the participant as they learned dances, with the system able to overlay computer graphics onto the image. The camera used to capture the image and motion of the participants was a Microsoft Azure Kinect camera. Three visual feedback types were developed and used as randomized conditions in the user study based on input from expert interviews and an online survey. These were Spheres, Rubber Bands, and Arrows. Three simple dance routines were developed, motion captured, and presented in random order in the user study. During the user study participants learned the dances by following a virtual instructor in the MR mirror (present for each condition), with the MR mirror providing a different form of visual feedback for each dance. After practicing a dance three times with the feedback, participants then performed the dance in front of the MR mirror following the virtual instructor without any feedback, and the system measured the accuracy of their performance by comparing the amount of time that the user’s joints, such as shoulders and elbows, were within desired bounds for each pose. Participants filled out an AttrakDiff Questionnaire describing their experience for each form of feedback, and gave comparative opinions of the different forms of visual feedback in a final interview. The results showed that participants performed best with the Arrows feedback variant which were a directional feedback showing their depth difference, however they ranked this variant the lowest based on their own preference. The most preferred form of feedback was Spheres, which were the simplest feedback, not providing any guidance into the correct pose, but participants performed poorest with them.Item Open Access Entering the realm of the wetlands: design and evaluation of engagement for a mobile augmented reality game(2024) Yin, WenliangThis thesis explores the potential of Augmented Reality (AR) in enhancing environmental edu- cation, with a focus on the conservation of New Zealand’s wetlands. Through the development and evaluation of a mobile AR game titled “NZ Wetlands Invasion,” this research investigates how different perspectives in the game impact player engagement and learning outcomes. Em- ploying a mixed-methods approach, the study integrates quantitative data from pre-test and post-test quizzes with qualitative feedback from participants to assess the effectiveness of AR in fostering environmental awareness and knowledge. Findings from this study reveal that the first-person view (FPV) in the AR game significantly enhances player engagement by providing a more immersive experience compared to the bird’s eye view (BEV). However, contrary to initial hypotheses, there was no significant difference in learning outcomes between FPV and BEV perspectives. This suggests that while FPV may offer a more engaging and immersive experience, both perspectives are equally effective in facilitating learning about wetland conservation. The research results also highlight the influence of environmental factors and physical comfort on the AR learning experience, underscoring the need for careful consideration of the physical and environmental context in which AR games are deployed. Additionally, the study addresses the concept of response shift bias, illustrating the complexity of measuring learning outcomes. In conclusion, this thesis contributes valuable insights into the design and implementation of AR in environmental education, offering recommendations for future AR game development aimed at engaging and educating users about environmental conservation. The findings suggest broader applications of AR in enhancing learning experiences across various domains, encouraging for the integration of immersive technologies in Game-Based Learning Environments(GBLEs) to boost a deeper understanding and appreciation of environmental issues.Item Open Access Trust and trustworthiness while exchanging virtual items in shared augmented reality.(2024) Ritter, MarkoIf the Metaverse is the visionary space that is poised to greatly expand human activity, building of interpersonal trust within the Metaverse must be possible. Trust has been described as a "lubricative" for business, innovation, resilience, and even general enjoyment. In its most basic dyadic form, peer-to-peer trading of virtual items with the means of shared augmented reality should be possible in a trustworthy manner. Here, we investigate how specific design choices to facilitate such a trade impact trust. A user study with 36 participants showed that the entailment of a mutual confirmation of an item exchange improves both trust towards the software system, as well as interpersonal trust. We further found that perceived closeness towards the trade peer remains a much greater influence on trust than any other effect. We also found strong correlations between user experience and trust. In summary, our research shows that shared augmented reality can provide a great environment for trade and bartering among physically co-located peers, because potentially defrauding behaviours can be impeded by explicitly displaying item ownership and safeguarding the transfer of ownership.Item Open Access Daddy long legs : a scale and speed up virtual reality locomotion technique for medium-scale scenarios.(2024) Zhao, YueThis study investigates the effectiveness of a novel natural walking-based locomotion technique, "Daddy Long Legs," for navigating medium-scale virtual scenarios. While real walking remains ideal for such scenarios, prolonged use can become physically demanding and inefficient. Conversely, artificial locomotion methods often induce disorientation or fatigue that comes from abrupt viewpoint changes or repeated gestures. Drawing inspiration from previous research on Seven-League Boots and Ground-Level Scaling, both with documented advantages and limitations, this study proposes a combined approach. We believed that their strengths and weaknesses could be effectively balanced through careful design, but there has been a lack of comprehensive study in this area. A user study involving 24 participants was conducted, in which they were required to perform a series of walking tasks within a medium-scale virtual garden. Furthermore, they did a Pre-Experiment Questionnaire and Post-Experiment Questionnaires, along with a brief one-on-one interview that specifically addressed their feelings and preferences regarding all the methods. Results indicate that Daddy Long Legs outperformed Seven-League Boots in all aspects. Notably, Ground-Level Scaling yielded the most natural walking behaviour, received the most positive feedback, and emerged as the preferred method.Item Open Access Immersive virtual reality for children in formal education.(2023) Belter, MeikeThis PhD thesis explored the integration of virtual reality (VR) technology into formal education, specifically targeting school-aged children. While VR has gained traction primarily for entertainment, this study sought to harness its immersive potential for educational purposes within, for example, schools. Games have long been recognized as valuable tools for enhancing learning experiences. In recent years, schools have increasingly adopted them, particularly in subjects such as math. Not all learning methods and tools are inclusive to all learners. Common challenges for children in a school context are inattention and hyperactivity. VR, with its ability to create immersive and customizable environments, presents an intriguing avenue for addressing these challenges. To address this, a VR math game was developed for this research, drawing from established educational frameworks and insights garnered from subject matter experts. Through qualitative interviews and thorough requirement analysis, the game’s design was refined. Subsequently, two user studies were conducted within real-world school environments. The initial study focused on assessing usability and refining the prototype based on user feedback. Encouraging outcomes paved the way for a more extensive second study. This followup delved into the influence of a reward system and virtual agent on the user experience, and comparing the VR game against a non-VR counterpart. The findings demonstrated that the VR game not only cultivated positive user experiences but also heightened motivation and engagement. Despite these promising results, further exploration is necessary to determine the role of ‘peerpresence’ in VR learning, and the game’s suitability for children with clinically diagnosed attention and hyperactivity issues. This research adds valuable insights into the process of creating inclusive and effective VR learning experiences. Through a comprehensive research approach, including design, usability testing, and user studies, the thesis underscored the potential of VR to enhance user engagement and experiences within educational contexts.Item Open Access Feeling moved in VR concerts.(2023) Aguilar, David J.This research explores the user experience design elements necessary to evoke the emotion called kama muta, most commonly known as” being moved” or “being touched”, in a virtual reality concert. Previous research has been able to mediate this emotion using video, nevertheless, to the best of my knowledge, no work has been done related to evoking kama muta in Virtual Reality. Accordingly, a VR experience prototype was created to simulate the performance of a fictional pop singer called X-ABC, who would have been dealing with grief as a consequence of his brother being missing and decides to share his feelings with the audience. Twenty participants took part in a between subjects’ study, in which they reported their emotional state using the KAMMUS Two, and Bailenson’s social presence questionnaires. Ultimately, participants’ answers were analysed using quantitative and qualitative methods. Overall, the findings suggest that it is possible to elicit kama muta in a simulation by featuring a narrative that increases the intensity of communal sharing relationships, such as loss, reunion, or memories of loved ones. It was also found that the user-experience design elements that contributed the most to the emotional response were a set of floating screens with portraits of the siblings when they were children, a believable voice acting and a character with emotional facial animations which were also lip-synced with the acted voice.Item Open Access Redirected hands for reducing arm fatigue during mid-air interactions in virtual reality.(2023) Hobson, AlexMuscle fatigue is a major impediment to the long-term usage and acceptance of Virtual Reality (VR). Users must routinely manipulate objects, perform repeated teleportations, and interact with user interface elements using prolonged arm and hand gestures. One leading strategy for reducing arm fatigue is ray-casting, which gives the user a laser pointer metaphor, allowing them to select objects with a comfortable position of the arms, but limits the fidelity of interactions by deviating from how hands are used in the real world. In this thesis a lesser-explored strategy to address arm fatigue is explored: hand redirection. “Hand redirection” is a technique made possible with VR, where the user can be fooled into believing their hand is in a different location to where it is in the real world, since people are visually dominant and VR completely immerses a person’s vision. Existing hand redirection literature mainly relates to being able to redirect the hand to a sparse haptic proxy, allowing the user to feel objects in VR, however its impact on arm fatigue is lesser explored. In this thesis, hand redirection is explored as a practical mitigation strategy addressing arm fatigue in VR, which still supports natural hand interactions (unlike ray-casting). A system was built that provides hand tracking and a physical surface at different heights, such that the user can touch the lower or tilted surface, and still see themselves touching an upright surface at eye level in VR. A between-subjects study was then conducted with 48 participants across six conditions, using a 2×3 mixed-factorial design, with two levels of redirection (Tilted, Redirected) and a control (No Redirection), with (Present) and without (Not Present) a physical surface on which to tap. The findings show that hand redirection is a valid way to reduce arm fatigue in VR, since arm fatigue was dramatically reduced without a significant impact on task performance. This behaviour differs when looking at results when the surface was present versus when it was not, suggesting that the way in which users behave in the presence of hand redirection is different when there is a physical surface to touch. Finally, the Tilted condition (where the board was rotated but not moved vertically) did not reduce arm fatigue, suggesting that the main way to reduce arm fatigue is to introduce a vertical offset rather than changing the angle that the hand interacts with the virtual content.Item Open Access Augmented reality for alternative measuring techniques in geospatial field work.(2023) Turton, DavidThis thesis assesses the value of a LiDAR application created for the the collection of data in geospatial field work. Several interfaces were developed for this tool with the purpose of determining the best method of selection in 3D space using augmented reality for data collection. Background research evaluates multiple tools and the validity of mobile LiDAR for measuring and data collection. Selection in 3D space using augmented reality is complex and multiple tools were analyzed for how they could be adapted for this task. Two user studies were performed. The first user study was performed with non- professional users aiming to evaluate the effectiveness of the different interfaces developed based on time taken, efficiency, accuracy, and user experience. The second user study consisted of interviews and test runs with GIS developers who analyzed the interfaces, gave feedback on them, and discussed how they compare to existing workflows in GIS data collection. Feedback from these studies was used to determine the best possible interface for the application, how the interfaces can be improved, and if it can operate as a potential alternative measuring tool to existing workflow.Item Open Access Acting aids in virtual production.(2023) Moisset, SylvainPrevious research has shown how using virtual production could solve some of the inherent problems that suffers the traditional film making workflow mainly by bringing more flexibility to the overall process, allowing more iterative work and more communication between all the departments involved. That being said, studies have also shown that for actors, working on a film that involves visual effects can put a lot of strain on their concentration and attention and lead to a frustrating experience for them and potentially less optimal results for the film. This project’s aim is to study if a virtual production setup can be used to provide actors, in a visual effects film making environment, with acting aids in the form of visual cues on a display. It also aims at studying which cues are more helpful for actors. A simple setup was designed to mimic the experience of acting in a professional virtual production volume. The system includes the possibility of displaying different cues within the virtual production environment. A user study was run on a sample of actors to identify if cuing using a virtual production setup leads to better results. Experts opinions were collected during the design phase of the project to assess the relevance of the project and get directions for the design of the prototype and the use study.Item Open Access TUFT-XR : exploring tactility for underfoot sensation with simulated fabric textures in extended reality.(2023) Topliss, JackThis thesis research focuses on the relationship between visual and tactile feedback and their impact on a person’s underfoot tactile perception of materials. Specifically, the research explores whether changing the visual appearance of materials affects a person’s underfoot tactile perception and which tactile perception is most affected by the change. Additionally, the study examines whether people are aware of changes in visual appearance when focused on other tasks. A mixed reality system was developed to answer these questions, and two tactile perception experiments were conducted. The first experiment involved 18 participants rating three tactile properties (roughness, hardness, and stiffness) for four different flooring materials, each with four different virtual overlays. The aim was to determine whether visual appearance affects tactile perception and whether materials with different tactile properties are impacted differently. Results indicated that tactile perception was most impacted by changes in visual appearance for roughness, and less so for more extreme tactile properties. The second experiment investigated whether users were aware of changes in tactile feedback when focused on a task in virtual reality. Eighteen participants walked around the experiment space standing on virtual objects, with two different materials covering the experiment flooring space. Nine participants each experienced virtual textures matching the flooring, and a single texture covered the experiment floor. Results showed that participants were more aware of walking between the different floorings when the visual appearance matched the flooring than when only a single texture was presented. Overall, the research demonstrates that visual appearance can impact tactile perception, particularly for roughness. Users are more aware of changes in tactile feedback when the visual appearance matches the flooring. These findings have implications for the development of immersive technologies in various fields, including product design.Item Open Access 5 Minute Volcano: designing serious games about volcanic hazards for a bi-cultural environment.(2023) Wall, KieronThis thesis proposal intends to asses how serious games can be designed to communicate volcanic tsunami risk in the bi-cultural environment of Aotearoa New Zealand. Background research has shown that children are vulnerable to natural hazards, yet crucial in risk communication. Serious games have been developed to help children learn, yet the research gaps are extensive. This research proposes working with a M¯aori kura to co-design a serious game for school children about tsunami risk communication and evacuation strategies. The tamariki engaged in workshops and through exploratory observational and interview qualitative methods, the prototype 5-Minute Volcano was designed, incorporating Māori and Western cultural aspects. The user study conducted observed a small group of four children whilst they played the game, and the feedback was used to determine if serious games can be used for learning and risk reduction in future studies.Item Open Access Exploring effective storytelling guidelines for cinematic virtual reality(2022) Tong, LingweiContent creators have been exploring ways to use virtual reality (VR) as an effective storytelling tool. The term cinematic virtual reality (CVR) was then created to describe the kind of VR experience that is produced using pre-rendered content with lengthier and complete story structures, with the interaction design that enables viewers to actively choose where to look. Initially, creators of CVR content began by transferring storytelling grammars and techniques from mature media, such as cinema and theater. However, specific challenges for CVR followed, including the narrative paradox (NP) (which is the conflict and tension arising between authorial control and viewer agency), the fear of missing out (FOMO), and the discrepancy between viewer expectations on agency and the system’s interactive capacity. Because CVR is a type of immersive experience, viewers are also inclined to interact with the story world freely. To achieve a final product that is a successful and engrossing storytelling experience, creators must address the NP and FOMO issues and establish a design balance between authorial control and viewer participation in terms of narrative progression. To investigate the issues raised above and assess potential solutions, several user studies were undertaken in this thesis. A human body-language-based attention guidance cue set called Action Units (AUs) was created to address the FOMO issue. It was then compared with two other commonly used synthetic cues for user experiences. According to the findings, the use of AUs in CVR content can boost viewer enjoyment and engagement with the story. The AUs were also favored by viewers for their diegetic qualities and by creators for the simplicity of use. Moving on to the NP issue, the second user study sought to identify the upper limit of a viewer’s desire to actively interact and participate in the narration. Results indicated that viewer control is advised for CVR projects. To handle viewer curiosity and motivate them to interact freely, creators must carefully set up the interactors. Based on the findings, a coherent framework was researched and developed by tying together previously acquired knowledge and rules that were dispersed to various components of producing CVR with the workflow that a creator uses to build the experience. The procedure resulted in a formalized framework called the Adaptive Playback Control (APC) for CVR. The APC starts by guiding content preparation by highlighting the need for applying diegetic attention guidance cues. It also includes guidelines for interactive design by emphasizing the need for design considerations regarding the harmony between viewer and creator roles in directing the narrative development, and raising the visibility of interaction affordances in the immersive storytelling experience. Then, a real-world case study of applying the APC to an immersive Māori (New Zealand indigenous people) storytelling experience was presented. The case study examined whether viewer-participatory design, including profiling viewers and the strategies to introduce narrative variations, was culturally appropriate. In this case study, personalized variations were added to CVR by taking into account both the unique demands of each viewer and their participation in the storytelling process. Insights from the case study showed that for creators to safely guarantee that experiences will live up to viewer expectations and be entertaining and diverse, individual users must also be taken into account from the very beginning of content design. Finally, this thesis offers the Adaptive Playback Control (APC), a novel frame- work for those who create CVR experiences. They can follow the framework’s instructions to create materials specifically designed for an immersive experience utilizing pre-rendered content, such as 360-degree videos. It intends to address the FOMO issue and help creators produce CVR experiences with correct viewer interaction and integrated viewer personalization, resolving the problem of NP and improving the overall experience. This thesis also employed a case study to show how adaptable the framework is and how it may be used in a larger context, in and beyond the cultural heritage sector.Item Open Access Gyroscope induced force feedback for ball impact simulation in exergames.(2022) Leete, HaydenA haptic feedback device for simulating batting sport haptics was designed using the resultant gyroscopic effect from rapidly reorienting spinning flywheels and integrated into a custom cricket themed virtual reality exergame. The device was capable of producing impact vibrations and a 0.1 N m torque. A within-subjects user study conducted on 16 participants, and player presence was evaluated using the Presence Questionnaire. The results of the user study were statistically insignificant due to a small sample size (p=0.153), and we were unable to reject the null hypothesis, but visual data analysis was used to identify trends that supported our hypothesis that increase haptic feedback fidelity increases presence in virtual reality batting sports exergames. Due to the statistical insignificance of these results, further research should be conducted to confirm these findings.Item Open Access Development of a volcanic hazard visualisation tool for risk communication(2022) Pourgolmohammadgolshani, AmiraliNew Zealand is one of the most vulnerable countries to the impacts of natural disasters. It is highly susceptible to geological disasters sch as earthquakes due to being located where the Pacific and Australian plates meet. New Zealand is home to 12 active volcanoes whose eruptions produce a wide variety of hazards, making the majority of the people living in New Zealand, susceptible to volcanic activity. Communication of geological risks is an important component of disaster risk management. Giving people who are at risk of being affected by volcanic hazards the right training and information is imperative for them to be able to make the correct decisions in the event of a disaster. With the advances in computer technologies, new and interactive methods of communication and visualisation are possible. In this paper we created and evaluated an interactive volcanic hazard simulation and visualisation application. This application is capable of visualising the landscape of mount Ruapehu in 3D. The ap- plication also uses mathematical model of volcanic ballistics to simulate the hazard allowing the user to create custom eruptions and view them. The application also outputs the data generated by these simulated volcanic particles which can be used to visualise the hazard footprint of various eruptions using a top down map of Ruapehu. A user study was conducted to evaluate whether such an application would allow volcanologist experts to better communicate volcanic hazard risks with the various stakeholders they engage with. Six volcanologists were interviewed and their feedback on the application was used to create a list of requirements for the future iterations of this application or to be used by other researchers and developers to create similar applications. The results of this study showed that volcanologist need interactive visualisation applications to better communicate with various communities to better disseminate critical information.
