Abstract
We developed a human-scale system which enable person to manipulate virtual objects by intuition with both hands. Though the system represented hands as single points, there were some troubles to manipulate objects in the virtual environment. We propose a method to represent hands as discs. But the system only knows the 3 dimentional points, so we decide the direction of the discs, using a presumption of person's intention with distribution maps of probability. We also developed a system which recognise hands as discs, and made a experiment to show a model of discs superior than one of points.
