Abstract
In order to make industrial products that fit the human body, the intuitive evaluation method is necessary. The virtual reality technology has been used for intuitive evaluation in various fields. For the developers of such products, simultaneous utilization of the virtual reality system would be potential demand, because the sensitivity in individuals and the exchanges of opinions with other people are important. Therefore, we proposed a virtual reality system which can be manipulated simultaneously by multi-users by using the GUI interface of tablet PCs and the centered large screen. By using this proposed method, we developed the deformation analysis system of the human hand shape using the finite element method for the multiple users.
