CoVR: A Large-Scale Force-Feedback Robotic Interface for Non-Deterministic Scenarios in VR
We present CoVR, a novel robotic interface providing strong kinesthetic
feedback (100 N) in a room-scale VR arena. It consists of a physical column
mounted on a 2D Cartesian ceiling robot (XY displacements) with the capacity of
(1) resisting to body-scaled users' actions such as pushing or leaning; (2)
acting on the users by pulling or transporting them as well as (3) carrying
multiple potentially heavy objects (up to 80kg) that users can freely
manipulate or make interact with each other. We describe its implementation and
define a trajectory generation algorithm based on a novel user intention model
to support non-deterministic scenarios, where the users are free to interact
with any virtual object of interest with no regards to the scenarios' progress.
A technical evaluation and a user study demonstrate the feasibility and
usability of CoVR, as well as the relevance of whole-body interactions
involving strong forces, such as being pulled through or transported.Comment: 10 pages (without references), 14 pages tota
