Abstract

Systems and methods according to the present invention address these needs and others by providing a handheld device, e.g., a 3D pointing device, which uses at least one sensor to detect motion of the handheld device. The detected motion can then be mapped into a desired output, e.g., cursor movement.

Claims

1. A method for controlling a system comprising the steps of:

detecting movement associated with a device;

determining if said movement indicates that said device is currently being held by a user; and

controlling said system based on a result of said determining step.

2. The method of claim 1, further comprising the step of:

identifying said user based upon a tremor pattern associated with said movement.

3. The method of claim 2, further comprising the step of:

selectively turning said system on based upon said step of identifying.

4. The method of claim 1, further comprising the step of:

turning said system on if said device is currently being held by a user.

5. The method of claim 2, further comprising the step of:

restricting access to said system based upon an identity of said user.

6. The method of claim 5, wherein said system is a media system and said step of restricting access further comprises the step of:

selectively permitting said user to access a media item based upon said identity.

7. The method of claim 2, further comprising the step of:

determining an identity of said user by comparing said tremor pattern with a plurality of stored tremor patterns.

8. The method of claim 7, wherein said tremor pattern and said plurality of stored tremor patterns are in the frequency domain.

9. The method of claim 7, wherein said tremor pattern and said plurality of stored tremor patterns are in the time domain.

10. The method of claim 7, wherein if a match does not occur between said tremor pattern and said plurality of stored tremor patterns, then said tremor pattern is stored.

11. The method of claim 7, wherein if a match does not occur between said tremor pattern and said plurality of stored tremor patterns, then said user is assigned a default set of system access permissions.

12. The method of claim 2, further comprising the step of:

retrieving preference settings associated with said user in response to said identifying step.
