When Tangibles Become Deformable: Studying Pseudo-Stiffness Perceptual Thresholds in a VR Grasping Task

Abstract

Compliant Stiff Compliant StiffBefore Deformation After DeformationVirtual Environment Sponge Tomato Matchbox Plastic Bottle LockFig. 1: When Tangibles Become Deformable: In the virtual environment, objects are displayed before and after being compressed, following a compliance-stiffness continuum (sponge, tomato, matchbox, water bottle, lock). In the real environment, a user is compressing a tangible object. Using pseudo-stiffness, she perceives this same range of stiffness, while only grasping a noncompressible object. We investigate the range of compliance and stiffness that can be elicited on a non-compressible tangible object.

“…Regarding rehabilitation methods, VR can be used in different contexts, in hospitals but also at home settings to promote the development of telemedicine and self-administered therapeutic approaches (Tieri et al, 2018 ). In addition, VR can manipulate the environment itself (Martens et al, 2019 ) and/or how the agent interacts with the virtual environment (Bouzbib et al, 2023 ), offering a unique opportunity to develop a fully controlled digital world, where responses and reactions are highly realistic and plausible (Slater, 2009 ).…”
