Abstract

Changing the path of a virtual object displayed in a stereographic form when a physical object is encountered in the path of the virtual object. Sensors may be used to identify the location of physical objects present in an area of interest (in the viewing area), and the determined location information may be used to determine whether a physical object is present in the path of a virtual object. In an embodiment, a gaming system receives the location information and determines whether a “collision” would occur. In an alternative embodiment, the sensor receives information of the original path of the virtual object, determines the new path based on location information and sends back the new path information to the gaming system.

Claims

1. A system comprising:

a processor;

a memory; and

a computer readable storage medium to store one or more instructions, which when retrieved into said memory and executed by said processor causes said system to perform a plurality of actions comprising;

determining an original 3-dimensional path of a virtual object;

rendering a stereoscopic display of said virtual object in said original path; and

if a physical object is present in said 3-dimensional path of said virtual object, identifying a new 3-dimensional path of the virtual object and continuing rendering of said virtual object in said new 3-dimensional path.

2. The system of claim 1, wherein said virtual object is rendered in said original 3-dimensional path in a first duration,

said virtual object in said original 3-dimensional path is found to collide with said physical object at a first time instance and said continuing in said new 3-dimensional path is performed in a second duration,

wherein said first time instance is after said first duration and said second duration is after said first time instance,

wherein said original 3-dimensional path is different from said new 3-dimensional path,

whereby a user perceives the path of said virtual object changing due to the presence of said physical object in said original 3-dimensional path.

3. The system of claim 2, further comprising a display screen, wherein said original 3-dimensional path is rendered to be coming out of said display screen, wherein said physical object is outside of said system.

4. The system of claim 3, further comprising a sensor to detect a location of said physical object, wherein identification of said new 3-dimensional path is performed based on said detected location.

5. The system of claim 4, wherein said sensor sends coordinates of said location to said processor, wherein said processor computes said new 3-dimensional path based on said received coordinates to identify said new 3-dimensional path.

6. The system of claim 4, wherein said sensor is designed to receive said original 3-dimensional path from said processor,

said sensor to compute said new 3-dimensional path based on the coordinates of said detected location and said received original 3-dimensional path, and sends said new 3-dimensional path to said processor,

whereby said identifying comprises receiving said new 3-dimensional path from said sensor.

7. The system of claim 4, wherein said processor and said memory are comprised in a gaming system, and said sensor is provided external to said gaming system,

wherein said virtual object is rendered while said user plays a game on said gaming system.

8. A method of enhancing user experience when displaying virtual objects using stereoscopic techniques, said method being implemented in a system, said method comprising:

determining an original 3-dimensional path of a virtual object;

rendering a stereoscopic display of said virtual object in said original path; and

if a physical object is present in said 3-dimensional path of said virtual object, identifying a new 3-dimensional path of the virtual object and continuing rendering of said virtual object in said new 3-dimensional path.

9. The method of claim 8, wherein said virtual object is rendered in said original 3-dimensional path in a first duration,

said virtual object in said original 3-dimensional path is found to collide with said physical object at a first time instance and said continuing in said new 3-dimensional path is performed in a second duration,

wherein said first time instance is after said first duration and said second duration is after said first time instance,

wherein said original 3-dimensional path is different from said new 3-dimensional path,

whereby a user perceives the path of said virtual object changing due to the presence of said physical object in said original 3-dimensional path.

10. The method of claim 9, wherein said original 3-dimensional path is coming out of a display screen, wherein said physical object is outside of said system and said display screen is part of said system.

11. The method of claim 10, wherein a location of said physical object is detected using a sensor, wherein said identifying is performed based on said location.

12. The method of claim 11, wherein said identifying further comprises receiving coordinates of said location, and computing said new 3-dimensional path based on said receiving.

13. The method of claim 11, further comprises sending data identifying said original 3-dimensional path to said sensor, wherein said sensor computes said new 3-dimensional path and sends back the computed new 3-dimensional to said system.

14. A computer readable medium storing one or more sequences of instructions causing a system to enhance user experience when displaying virtual objects using stereoscopic techniques, wherein execution of said one or more sequences of instructions by one or more processors contained in said system causes said system to perform the actions of:

determining an original 3-dimensional path of said virtual object;

rendering a stereoscopic display of said virtual object in said original 3-dimensional path; and

identifying a new 3-dimensional path of the virtual object and continuing rendering of said virtual object in said new 3-dimensional path if a physical object is present in said 3-dimensional path of said virtual object.

15. The computer readable medium of claim 14, wherein said virtual object is rendered in said original 3-dimensional path in a first duration, wherein said physical object is found to be in said original 3-dimensional path at a first time instance,

wherein said continuing in said new 3-dimensional path is performed in a second duration,

wherein said first time instance is after said first duration and said second duration is after said first time instance,

wherein said original 3-dimensional path is different from said new 3-dimensional path,
