We report on two experiments that deploy low-frequency audio and strong vibrations to induce haptic-like sensations throughout the human body. Vibration is quite frequently deployed in immersive systems, for example to provide collision feedback, but its actual effects are not well understood [Kruijff & Pander 2005; Kruijff et al. 2015]. The starting point of our experiments was a study by Rasmussen [Rasmussen 1982], which found that different vibration frequencies were experienced differently throughout the body. We will show how vibrations affect sensations throughout the body and may provide some directional cues to some parts of the body, yet also illustrate the difficulties.
