Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
73 words
A sound system for use in creating the illusion of holgraphic sound in an artificial reality system, said sound system comprising: a headband to be worn by a listener; a plurality of discrete vibratory elements placed circumferentially around said headband, said elements each adapted for receiving electrical impulse signals and for producting sound waves in response thereto; and a processor for selectively producing said electrical impulse signals to drive the discrete vibratory elements.
Claim 2
Dependent Claim
73 words
A sound system for use in creating the illusion of holgraphic sound in an artificial reality system, said sound system comprising: a headband to be worn by a listener; a plurality of discrete vibratory elements placed circumferentially around said headband, said elements each adapted for receiving electrical impulse signals and for producting sound waves in response thereto; and a processor for selectively producing said electrical impulse signals to drive the discrete vibratory elements.
Claim 3
Dependent Claim
14 words
The system set forth in claim 1 wherein said vibratory elements are piezoelectric strips.
Claim 4
Dependent Claim
151 words
The system set forth in claim 1 wherein said artificial reality system is operable for creating artificial viewing environments for a plurality of viewers, said environments each including predefined structures, said artificial reality system comprising: a geographical sensor connectable to each said viewer for providing data pertaining to the relative movement of each of said viewers; a processor local to each of said viewers for accepting said data from each of said viewers and from a plurality of other viewers; and a presentation media for providing views of said created environment to each of said viewers, said views controlled by said local processor and dependent upon said accepted data from each of said viewers and data from said other of said viewers; and wherein said processor is further operative for coordinating the provision of said impulse signals to said elements in association with said provided views to each of said viewers.
Claim 5
Dependent Claim
42 words
The system set forth in claim 3 wherein said artificial environment for each of said viewers is created by said local processor and wherein the environment and said impulse signals for each of said viewers is unique to each of said viewers.
Claim 6
Dependent Claim
120 words
The system set forth in claim 1 wherein said artificial reality system is operable for creating an artificial viewing environment for a viewer, said environment including predefined structures, said artificial reality system comprising: a geographical sensor connectable to said viewer for providing data pertaining to the relative movement of said viewer; a processor local to said viewer for accepting said data from said viewer; a presentation media for providing views of said created environment to said viewer, said views controlled by said local processor and dependent upon said accepted data from said viewer; and wherein said processor is further operative for coordinating the provision of said impulse signals to said elements in association with said provided views to said viewer.
Claim 7
Independent Claim
64 words
The method of creating a sound system comprising the steps of: placing a headband around the head of a listener; distributing a plurality of discrete vibratory elements circumferentially around said headband, said elements each adapted for receiving electrical impluse signals and for producing sound waves in response thereto; and driving said discrete vibratory elements by a processor, said processor producing said electrical impluse signals.
Claim 8
Independent Claim
64 words
The method of creating a sound system comprising the steps of: placing a headband around the head of a listener; distributing a plurality of discrete vibratory elements circumferentially around said headband, said elements each adapted for receiving electrical impluse signals and for producing sound waves in response thereto; and driving said discrete vibratory elements by a processor, said processor producing said electrical impluse signals.
Claim 9
Dependent Claim
38 words
The method set forth in claim 6 further comprising the step of: providing electrical impulses to selected discrete elements in accordance with the direction of origin from which a particular sound is to be perceived by said listener.
Claim 10
Dependent Claim
14 words
The method set forth in claim 7 wherein said vibratory elements are piezoelectric elements.
Claim 11
Dependent Claim
39 words
The method set forth in claim 6 further comprising the step of: associating said sound with an artificial reality system which is operable for creating artificial viewing environments for a plurality of listeners, said environments each including predefined structures.
Claim 12
Dependent Claim
95 words
The method set forth in claim 9 further comprising the steps of: connecting a geographical sensor to each of said listeners for providing data pertaining to the relative movement of each of said listeners; accepting, via a processor local to each said listener, said data from each of said listeners and from a plurality of other of said listeners; and providing views of said created environment to each said listeners, said views controlled by said local processor and dependent upon said accepted data from each said listeners and data from said other of said listeners.
Claim 13
Dependent Claim
41 words
The method set forth in claim 9 wherein said artificial environment for each said listeners is created by said local processor and wherein the environment and said impulse signals for each of said listeners is unique to each of said listeners.
