Understanding and Mitigating Encountered-Type of Haptic Devices Failure Modes in VR Encountered-type of Haptic devices (ETHD) are robotic interfaces physically overlaying virtual counterparts prior to a user interaction in Virtual Reality. They theoretically reliably provide haptics in Virtual environments, yet they raise several intrinsic design challenges to properly display rich haptic feedback and interactions in VR applications. In this paper, we use a Failure Mode and Effects Analysis (FMEA) approach to identify, organise and analyse the failure modes and their…

Survey of Virtual Reality Interactions via Haptic Solutions In the past few years, the terms “Virtual Reality” and “Haptics” have been amongst the most quoted keywords in HCI conferences. Why enabling haptics in VR? Virtual Reality experiences are evaluated in terms of presence. Presence is the feeling of being in another place than the one we are actually in. It heavily relies on the users’ senses. Currently, immersion and realism levels in terms of vision and auditory cues are really…

A Large-Scale Force-Feedback Robotic Interface for Non-Deterministic Scenarios in VR CoVR is a physical column mounted on a 2D Cartesian ceiling robot to provide strong kinesthetic feedback (over 100N) in a room-scale VR arena. The column panels are interchangeable and its movements can safely reach any location in the VR arena thanks to XY displacements and trajectory generations avoiding collisions with the user. When CoVR is static, it can resist to body-scaled users’ actions, such as (A) users pushing on…
