ABSTRACT:
A method of interacting with one or more objects in a virtual reality (VR) space. A user input establishes a pointing mode, whereupon a visual indicator, such as a pointer, is displayed on the user's viewing device, and the visual indicator is moved on the viewing device to refer to an object in the VR space, in response to actuation of a pointing device such as a mouse, joystick or pen. An image of the user's avatar may also be displayed in the VR space, and the avatar may have an appendage or pointing appliance to point to a target in the 3-D space. A user can point in this manner with high precision, as well as draw illustrations, etc. Other users (viewers) of the same VR space can see the first user's avatar pointing to the target. Another viewer's display can be dynamically adjusted to present an appropriate perspective of the VR space to show the target.
