Appeal No. 2000-0829
Application 09/079,054
U.S. Patent 5,307,295, issued April 26, 1994, based on
application 07/641,031, filed January 14, 1991.
The invention
5. The disclosed invention pertains to a virtual reality
stage lighting system with a memory, processor, a display unit
and a virtual reality user interface in which a user may select a
light. Once the light is selected a list of options appears so
that the user may select the option it wants for controlling the
selected light.
6. The independent claims are reproduced as follows:
1. A virtual reality stage lighting design tool comprising:
a memory storing information representing a plurality of
lighting devices and lighting effects that can be produced by
said lighting devices;
a processor, coupled to the memory, simulating a lighting
display based on said information;
a virtual reality display unit, coupled to the processor,
and displaying said lighting simulation to a user as a simulated
three dimensional representation of lighting simulation; and
a virtual reality user interface, responsive to three
dimensional motion of an operator, to simulate and display the
operators actions and responses thereto in selecting one of the
lighting devices for modification by graphical reference to one
of the simulated lighting devices displayed on the virtual
reality display unit, the processor modifying the simulated
lighting display responsive to said modification to produce a new
lighting simulation so as to reflect the selection of lighting
devices and modification options, said virtual reality user
interface allowing the user to select a lighting device from said
plurality of lighting devices, and operating to determine, from
said memory, information about the selected lighting device,
