Abstract

A projection device (100), and method for operating the projection device is provided herein. During operation a projection device will determine a current context, and then associate the context and the display parameters. The association is stored so that the projection device will operate using the display parameters the next time the context is realized.

Claims

1. A method for operating a projection device, the method comprising the steps of:

determining, by the projection device, a location for the projection device;

adjusting, by the projection device, display parameters based on the device'"'"'s location; and

projecting an image using the display parameters.

2. The method of claim 1 wherein the display parameters comprise brightness, orientation, resolution, color, a starting point of a presentation, or application metadata.

3. The method of claim 1 wherein the step of determining the location comprises the step of determining nearby access points.

4. The method in claim 1 where the step of determining the location comprises the step of using a triangulation scheme based on the location of multiple access points.

5. A method comprising the steps of:

determining by a projection device, a context for the projection device;

determining by the projection device, display parameters for the projecting device;

associating by the projection device, the context and the display parameters; and

storing by the projection device, the association so that the projection device will operate using the display parameters when the context is realized.

6. The method of claim 5 wherein the context comprises a location.

7. The method of claim 5 wherein the context comprises an identification of users in a vicinity.

8. The method of claim 7 wherein the context additionally comprises metadata from a file being projected.

9. A method for operating a projection device, the method comprising the steps of:

determining by the projection device, devices in proximity to the projection device;

adjusting by the projection device, display parameters based on the devices in proximity; and

displaying by the projection device, a first image using the display parameters.

10. The method of claim 9 further comprising the step of sending data to a device in proximity to the projection device.

11. The method of claim 10 wherein the data comprises caller identification data, a connectivity or signal strength indicator, battery indicator.

12. The method of claim 10 wherein the data comprises a phone call.

13. The method of claim 9 wherein the device in proximity to the projection device comprises a watch, headset, or a phone.

14. The method of claim 9 further comprising the steps of:

receiving message;

displaying by the projection device, a second image using the display parameters, wherein the second image is displayed in response to the received message and indicates the message was received.

15. A projection device comprising:

context-aware circuitry determining a location for the projection device;

logic circuitry, adjusting display parameters based on the device'"'"'s location; and

projection circuitry projecting an image using the display parameters.

16. The projection device of claim 15 wherein the display parameters comprise brightness, orientation, resolution, color, a starting point of a presentation, or application metadata.

17. The projection device of claim 15 wherein the context-aware circuitry determines the location by determining a nearby access point.
