Item Open Access Sharing Manipulated Heart Rate Feedback in Collaborative Virtual Environments(2019) Dey A; Chen H; Hayati A; Billinghurst M; Lindeman RWe have explored the effects of sharing manipulated heart rate feedback in collaborative virtual environments. In our study, we created two types of different virtual environments (active and passive) with different levels of interactions and provided three levels of manipulated heart rate feedback (decreased, unchanged, and increased). We measured the effects of manipulated feedback on Social Presence, affect, physical heart rate, and overall experience. We noticed a significant effect of the manipulated heart rate feedback in affecting scariness and nervousness. The perception of the collaborator’s valance and arousal was also affected where increased heart rate feedback perceived as a higher valance and lower arousal. Increased heart rate feedback decreased the real heart rate. The type of virtual environments had a significant effect on social presence, heart rate, and affect where the active environment had better performances across these measurements. We discuss the implications of this and directions for future research.Item Open Access What you say is not what you get: Arguing for Artificial Languages Instead of Natural Languages in Human Robot Speech Interaction(2009) Mubin, O.; Bartneck, Christoph; Feijs, L.The project described hereunder focuses on the design and implementation of a “Artificial Robotic Interaction Language", where the research goal is to find a balance between the effort necessary from the user to learn a new language and the resulting benefit of optimized automatic speech recognition for a robot or a machine. We also discuss the rationale of creating our artificial language and highlight the possibility of improving speech recognition by virtue of an artificial language. In conclusion we present the methodology by which we have designed an initial vocabulary of our artificial language.Item Open Access The Invisible Naked Guy: An exploration of a minimalistic robot(2013) Partridge, M.; Bartneck, ChristophThe development of convincing androids is currently constraint by the limitations of artificial intelligence. Instead of developing even more realistic human-like robots we attempt to push the opposite design direction to its extreme. We developed a most minimalistic robot that can still maintain an interesting interaction with users.It consists only of two animated slippers on a box. We exhibited this design exploration at in front of a museum and the responses very highly encouraging. With only a minimal set of clues we were able to create an anthropomorphic illusion.Item Open Access Cross-Cultural Study of Expressive Avatars(2004) Bartneck, Christoph; Takahashi T; Katagiri YAvatars play an important role in international online communities. While certain simple expressions, such as facial emotional expressions are cultural independent, more complex expressions might not be. Therefore we conducted a cross-cultural study to investigate the influence of the users’ cultural background (Japanese or Dutch) on their perception of avatar’s expressions in terms of perceived arousal and valence. A significant gender difference was found for valence. Women and in particular Japanese women rated the expressions more positive.
