Abstract
In distributed shared virtual space, we need to have awareness controled and offered smoothly for realization of a natural and effective system. Benford has defined "aura" which controls the quantities of awareness according to the distance between avators. But if we calculate all avators' aura in the virtual space, it is difficult to offer awareness smoothly because of the huge amount of calculation. If we restrict the quantity of awareness which can be treated simultaneously, it is not guaranteed that awareness is offered from a nearer avator although we can reduce the calculate time. In this paper, we propose the aura calculation based on mesh approach. In this approach, we can reduce the calculation time by dividing virtual space into mech and making search area smaller. We can also offer awareness from a nearer avatar by the turn of the searcing mesh. At the last of this paper, we evaluate the validity of this approach.
