Abstract

An input device is disclosed, one embodiment of which provides position information to an information handling system (IHS). The position information includes both location information and spatial orientation information of the input device in real space. The input device includes a location sensor which determines the absolute location of the input device in x, y and z coordinates. The input device also includes a spatial orientation sensor that determines the spatial orientation of the input device in terms of yaw, pitch and roll. The input device further includes a processor that processes the location information and the spatial orientation information of the input device in real space to determine an image view from the perspective of the input device in virtual space. Movement of the input device in real space by a user causes a corresponding movement of an image view from the perspective of the input device in virtual space. The input device itself displays the image view, or alternatively, an IHS to which the input device couples displays the image view.

Claims

1. A method of operating an input device to provide position information that includes location information and spatial orientation information of the input device, the method comprising:

determining, by a location sensor in the input device, the location of the input device in real space, thus providing the location information;

determining, by a spatial orientation sensor in the input device, the spatial orientation of the input device in real space, thus providing the spatial orientation information; and

processing, by a processor, the location information and the spatial orientation information of the input device in real space to determine an image view from the perspective of the input device in virtual space.

2. The method of claim 1, wherein the determining the location step further comprises determining the location of the input device in one of an xy plane and an xyz coordinate system.

3. The method of claim 1 further comprising displaying, by a display in the input device, the image view.

4. The method of claim 1 further comprising displaying, by an information handling system external to the input device, the image view.

5. The method of claim 1 further comprising offloading, by the processor, at least a portion of the processing step to an information handling system coupled to the input device.

6. The method of claim 1, wherein the determining the location step is performed by a global positioning system type location sensor.

7. The method of claim 1, wherein the determining the spatial orientation step is performed by a tilt sensor type spatial orientation sensor.

8. The method of claim 1, wherein the determining the spatial orientation step determines the pitch, roll and yaw of the input device.

9. An input device for providing position information including location information and spatial orientation information of the input device, the input device comprising:

a location sensor that determines the location of the input device in real space to provide the location information;

a spatial orientation sensor that determines the spatial orientation of the input device in real space to provide the spatial orientation information; and

a processor, coupled to the location sensor and the spatial orientation sensor, that processes the location information and the spatial orientation information of the input device in real space to determine an image view from the perspective of the input device in a virtual space.

10. The input device of claim 9, wherein the location information includes the real time location of the input device in one of an xy plane and an xyz coordinate system.

11. The input device of claim 9, further comprising a display, coupled to the processor, that displays the image view from the perspective of the input device in a virtual space.

12. The input device of claim 9, wherein the input device couples to an information handling system (IHS) external to the input device, the IHS including a display that displays the image view.

13. The input device of claim 9, wherein the input device couples to an information handling system (IHS) external to the input device such that at least a portion of the processing of the location information and spatial orientation information is offloaded to the IHS external to the input device.

14. The input device of claim 9, wherein the location sensor comprises a global positioning system type location sensor.

15. The input device of claim 9, wherein the spatial orientation sensor comprises at least one of a digital compass and a tilt sensor.

16. The input device of claim 9, wherein the spatial orientation sensor determines the pitch, roll and yaw of the input device.
