Project Description

We will construct virtual rheological objects in VR space and will realize haptic sensation at the contact with rheological objects. Research topics include reality-based modeling of rheological objects, volmatic visualization of deformation inside rheological objects from CT and ultrasonic images, and haptic rendering of rheological deformation.
2007/11/2 Workshop on Modeling, Identification, and Control of Deformable Soft Objects
in conjunction with IROS 2007, San Diego, U.S.A.
2005/4/22 Proposal for Grant-in-Aid for Scientific Research "Reality-based Modeling of Deformable Soft Objects via Internal Sensing" was accepted. (HP)
2002/6/7 Proposal for Grant-in-Aid for Scientific Research Visual and Haptic Rendering for Virtual Rheological Objects was accepted.

There exist many deformable soft objects that show rheological nature in our environment. We have to construct these rheological objects in a virtual world for the virtual reality. In this project, we will construct Virtual Rheological Objects in VR space and will realize haptic sensation caused by rheological objects.

Research topics include 1) Reality-based modeling of rheological objects, 2) Volmatic visualization of deformation inside rheological objects from CT and ultrasonic images, and 3) Haptic rendering of rheological deformation.
