Persuasive Vibrations: Effects of Speech-Based Vibrations on Persuasion,
Leadership, and Co-Presence During Verbal Communication in VR

Tactile feedback consisting in vibrations synchronized with speech can improve the persuasiveness, leadership and co-presence of avatars in VR. Users also perceive their speech as more persuasive when augmented with haptic feedback.

Cable driven haptic interface for co-localized desktop VR

This interface allows to simulate force feedback co-located with a VR environment displayed on a computer screen.

Assisted walking-in-place: Introducing assisted motion to
walking-by-cycling in embodied Virtual Reality

Lead author : Yann Moullec (Inria)

We introduce a motorized bike to support the walk of a self-avatar in Virtual Reality. Existing walking-in-place techniques can be judged repetitive and strenuous while our approach provide a compelling walking experience while reducing the effort required to navigate.

Influence of user posture and virtual exercise on impression of locomotion during VR observation

Users in standing, sitting, or lying positions may feel like they are walking, jogging, or stepping over obstacles in VR without actually moving.

Multi-sensory display of self-avatar’s physiological state: virtual breathing and heart beating can increase sensation of effort in VR

Lead author : Yann Moullec (Inria)

We introduce haptic belt to simulate fake breathing. It can for example increase the sensation of effort and embodiment when watching an avatar moving in VR.

Effect of vibrations on impression of walking and embodiment with first-and third-person avatar

Vibrations simulating the foot/ground contact during a virtual walk improve the sensation of walking and embodiment of static users observing 1PP or 3PP avatar.

Identifying Tactors Locations on the Proximal Phalanx of the Finger for Navigation

Vibrotactile feedback displayed by a ring-type interface can provide directional cues for navigation.
