| Research Abstract |
Two-handed interactions are efficient to design a three dimensional (3D) object, hence a two-handed spatial interface device must facilitate such a design process in a virtual environment. In order to realize a virtual environment in which an operator can use his/her hands efficiently, it is necessary to implement a virtual reality system that is suitable to human's ability of sensory integration. We ca unconsciously integrate many kinds of sensory information, e.g.visual and kinesthetic sensation.
This project was about constructing a virtual work space for performing any tasks by two-handed-input. We use a three dimension spatial interface device that allows users to handle virtual objects directly by free hands and be feel-able some physical properties of virt object : for example, weight of virtual objects when they are held, force that is the reaction from virtual objects when users touch them force from a collision of two virtual objects which users can feel in some operations such as placing one virtual object onto another one.
We have shown some evidences about force feedback sensation, and perceptual integration between kinesthetic and visual sensat that can encourage users to accomplish any tasks by cooperation between both hands in natural manner.
