Psychophysics of wearable haptic/tactile perception in a multisensory context

Abstract

Multisensory lab based in Peking University, has carried out basic studies in multisensory space and time processing, intersensory binding and haptic / tactile perception. We exploited a typical paradigm of multisensory illusion-temporal ventriloquist effect and applied it in a wide range of multisensory interactions (mainly focused on temporal processing). In this work, we summarized how the tactile stimuli were exploited to compose tactile cues and as tactile apparent motion to interface with other sensory stimuli (visual and auditory stimuli) to examine the underlying perceptual organization in a multisensory context. Moreover, we introduced two examples of wearable haptic/tactile perception in our lab, by using two customized tactile devices and discussed the potential applications in this field.

The configuration and experience mapping of an accessible VR environment for effective design reviews

“…These can be awkward in requiring the user to bend over, and the control mappings to access, use and store different tools is not generally obvious. More advanced implementations that make use of multisensory interactions, such as wearable haptics (Lei et al ., 2019), point to how accessibility could be improved. Controls on controllers appear above the physical object the user is holding, with additional options usually included in VR.…”

HapBead: On-Skin Microfluidic Haptic Interface using Tunable Bead

“…The device can be triggered with different motion patterns at very high speed, to give a sense of apparent motion, in accord to cutaneous rabbit and other haptic illusions. In these illusions, a sequence of taps at two separated skin locations results in the perception that intervening skin regions were also tapped [46]. Hapbead can operate on the same principle and create such haptic illusions (9c).…”
