METHOD AND SYSTEM FOR PROVIDING VISUAL FEEDBACK IN A VIRTUAL REALITY ENVIRONMENT

摘要

A method of providing visual feedback to a user in a virtual reality environment comprises: capturing (102) position and depth information of the user using a depth sensor (204); determining (104) a potential interaction point between the user and a 3D virtual object (206) associated with the virtual reality environment based on the position and depth information of the user; determining (106), using a virtual depth camera, depth of the 3D virtual object at the potential interaction point; calculating (108) a distance between the user and the 3D virtual object based on the position and depth information of the user and the depth of the 3D virtual object; and rendering (110) a soft shadow of the user on the 3D virtual object based on the distance between the user and the 3D virtual object.
