Abstract
Abstract A method and apparatus for creating sounds in a virtual world. The system provides signal processing capabilities to convert monaural sounds to fully spacialized sound sources. A user of the system wearing a pair of stereo headphones perceives live, computer generated, or recorded sounds as coming from specific locations in space, just a listener does in the real world.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
88 words
An audio feedback system for use with a virtual reality system, comprising: means for calculating a virtual world; a sensor, connected to the means for calculating, for sensing information of a person's hand; an audio feedback determining means, connected to the means for calculating and the sensor, for determining if audio feedback is to be generated, using information of the virtual world and the information of the person's hand; and a sound generator for generating sound in response to the determination made by the audio feedback determining means.
Claim 2
Dependent Claim
88 words
An audio feedback system for use with a virtual reality system, comprising: means for calculating a virtual world; a sensor, connected to the means for calculating, for sensing information of a person's hand; an audio feedback determining means, connected to the means for calculating and the sensor, for determining if audio feedback is to be generated, using information of the virtual world and the information of the person's hand; and a sound generator for generating sound in response to the determination made by the audio feedback determining means.
Claim 3
Dependent Claim
45 words
A system according to claim 1, wherein the audio feedback determining means includes: means for determining audio feedback is to be generated which indicates an object in the virtual world is grabbable using information of the virtual world and the information of the person's hand.
Claim 4
Dependent Claim
46 words
A system according to claim 1, wherein the audio feedback determining means includes: means for determining audio feedback is to be generated which indicates an object in the virtual world can be picked up using information of the virtual world and information of the person's hand.
Claim 5
Dependent Claim
48 words
A system according to claim 1, wherein the audio feedback determining means includes: means for determining audio feedback is to be generated which indicates an object which was held in the virtual world has been released using information of the virtual world and information of the person's hand.
Claim 6
Dependent Claim
21 words
A system according to claim 1, wherein: the audio feedback determining means operates without analyzing an orientation of the person's head.
Claim 7
Dependent Claim
16 words
A system according to claim 1, wherein: the sensor senses gestures made by the person's hand.
Claim 8
Dependent Claim
35 words
A system according to claim 1, wherein the audio feedback determining means comprises: means for determining a predetermined sound is to be generated using information of the virtual world and information of the person's hand.
Claim 9
Independent Claim
56 words
A method of generating audio feedback, comprising the steps of: creating a virtual world; sensing information of a person's hand; determining if audio feedback is to be generated using information of the virtual world and the information of the person's hand; and generating sound when the determining step determines that audio feedback is to be generated.
Claim 10
Independent Claim
56 words
A method of generating audio feedback, comprising the steps of: creating a virtual world; sensing information of a person's hand; determining if audio feedback is to be generated using information of the virtual world and the information of the person's hand; and generating sound when the determining step determines that audio feedback is to be generated.
Claim 11
Dependent Claim
49 words
A method according to claim 8, wherein the step of determining if audio feedback is to be generated comprises: determining audio feedback is to be generated which indicates an object in the virtual world is grabbable using information of the virtual world and the information of the person's hand.
Claim 12
Dependent Claim
51 words
A method according to claim 8, wherein the step of determining if audio feedback is to be generated comprises: determining audio feedback is to be generated which indicates an object in the virtual world can be picked up using information of the virtual world and the information of the person's hand.
Claim 13
Dependent Claim
57 words
A method according to claim 8, wherein the step of determining if audio feedback is to be generated comprises: determining audio feedback is to be generated which indicates an object in the virtual world which was held in the virtual world has been released using information of the virtual world and the information of the person's hand.
Claim 14
Dependent Claim
35 words
A method according to claim 8, wherein the step of determining if audio feedback is to be generated comprises: determining if audio feedback is to be generated without analyzing an orientation of the person's head.
Claim 15
Dependent Claim
18 words
A method according to claim 8, wherein the sensing step comprises: sensing gestures made by the person's hand.
Claim 16
Dependent Claim
32 words
A method according to claim 8, wherein the determining step comprises: determining a predetermined sound is to be generated using information of the virtual world and the information of the persons's hand.
Claim 17
Independent Claim
93 words
A method of generating audio feedback in a virtual world, comprising the steps of: creating a virtual world include a virtual object; sensing information of a person's hand; generating a first sound when the information sensed of the person's hand and the virtual object make the object grabbable; generating a second sound when the information sensed of the person's hand and the virtual object indicate that the hand has intersected the virtual object; and generating a third sound when the information sensed of the person's hand and indicates that the object is released.
Claim 18
Independent Claim
93 words
A method of generating audio feedback in a virtual world, comprising the steps of: creating a virtual world include a virtual object; sensing information of a person's hand; generating a first sound when the information sensed of the person's hand and the virtual object make the object grabbable; generating a second sound when the information sensed of the person's hand and the virtual object indicate that the hand has intersected the virtual object; and generating a third sound when the information sensed of the person's hand and indicates that the object is released.
Claim 19
Dependent Claim
20 words
A method according to claim 15, wherein: the steps of generating the first, second, and third sounds generate different sounds.
