Haptic feedback improves the overall realism of the interaction between users and virtual characters

In this article we briefly explain a new paper by Inria with title Crowd Navigation in VR: exploring haptic rendering of collisions

In the PRESENT project, Inria is exploring novel manners of enabling interactions between users and virtual agents, both at the individual and collective levels. In this context, Inria recently investigated the use of wearable haptics as a modality to communicate novel types of information from the virtual agents to the user. Wearable haptic interfaces are an easy and unobtrusive way to convey contact sensations, as they can provide rich information without impairing the user’s motion. As haptics is a prominent sense in our lives, its use is expected to be paramount to convey realistic and compelling interactions.

A recent evaluation by Inria of haptic rendering of contact when a user interacts with a crowd virtual humans has been published in the high-impact journal IEEE Transactions on Visualization and Computer Graphics, you can read the paper here. It demonstrated that providing haptic feedback improves the overall realism of the interaction between the user and the virtual characters. In particular, participants more actively avoided collisions with the virtual characters when they experienced haptic rendering of contacts, therefore demonstrating changes in their localized interactions.These results confirmed that haptic rendering can therefore be relevant to communicate novel types of information from the virtual agents to the user, which Inria wants to further explore so as to create more expressive and interactive virtual characters.
