Haptic-Auditory Distance Cues in Virtual Environments: Exploring Adjustable Parameters for Enhancing Experience
نویسندگان
چکیده
This paper investigates two subjective responses to a recorded percussive musical instrument sound displayed in a hapticauditory virtual environment; the responses were Apparent Motion Towards (AMT) and Powerfulness. The system employed a wholebody actuator and a full-range multichannel stereophonic sound compliant with ITU standards. AMT was experienced when whole-body vibratory components were slightly delayed in relation to sound components. Furthermore, the recorded percussive hit was initially observed to vary in its apparent power with variation in intermodal delay values and level; participants, therefore, made ratings of Powerfulness. Threshold intermodal delays for experiencing AMT were found to depend strongly upon intermodal level values, but ratings of Powerfulness were found to depend primarily upon whole-body vibration levels. These results can be incorporated into a structure for control response parameters in multimodal environmental display systems incorporating sound and whole-body vibration.

Exploring the influence of haptic and olfactory cues 1 Exploring the influence of haptic and olfactory cues of a virtual donut on satiation and eating behavior
Olfactory research in immersive virtual environments (IVEs) have often examined the addition of scent as part of the environment or atmosphere that act as experimental stimuli. There appears to be a lack of research on the influence of virtual foods in IVEs on human satiation. Studies based on situational cues or self-perception theory provide support for the hypothesis that touching and smelli...

People who are blind tend to adopt sequential, route-based strategies for moving around the world (Golledge et al, 1996). Common strategies take the self as the main frame of reference, but those who perform better in navigational tasks use more spatial, map-based strategies (Hill et al, 1993). Training in such strategies can improve performance (Cummins and Rieser, 2008; Simonnet et al, 2006)....

How do users generate an illusion of presence in a rich and consistent virtual environment from an impoverished, incomplete, and often inconsistent set of sensory cues? We conducted an experiment to explore how multimodal perceptual cues are integrated into a coherent experience of virtual objects and spaces. Specically, we explored whether intermodal integration contributes to generating the ...
متن کاملThe effects of substitute multisensory feedback on task performance and the sense of presence in a virtual reality environment
Objective and subjective measures of performance in virtual reality environments increase as more sensory cues are delivered and as simulation fidelity increases. Some cues (colour or sound) are easier to present than others (object weight, vestibular cues) so that substitute cues can be used to enhance informational content in a simulation at the expense of simulation fidelity. This study eval...
