Abstract

A system (50) and method (10) providing a user with a qualitative indication of a freshness of location information with minimal user disruption can include the steps of obtaining (12) presentation data, associating (14) a location indication representative of a location when the presentation data was obtained, and altering (16) a data characteristic of the presentation data over time to provide an indication of a freshness of the location indication. The method can further include the step of presenting (19) the presentation data to a user. Note, presentation data for example can be data for a digital photograph or an audio sample. The step of altering the data characteristic can optionally involve altering (18) at least one among a contrast, brightness, sharpness, pixel resolution, vertical positioning, horizontal positioning, color setting, white balance, compression ratio, language setting, volume, pitch, and equalization setting.

Claims

1. A method for indicating a freshness of data used in a context aware application, comprising the steps of:

obtaining presentation data;

associating a location indication representative of a location when the presentation data was obtained; and

altering a data characteristic of the presentation data over time to provide an indication of a freshness of the location indication.

2. The method of claim 1, wherein the method further comprises the step of presenting the presentation data to a user after altering the data characteristic.

3. The method of claim 1, wherein the step of obtaining presentation data comprises the step of obtaining at least one among a digital photograph and an audio sample.

4. The method of claim 1, wherein the step of altering the data characteristic comprises at least one among altering a contrast, brightness, sharpness, pixel resolution, white balance, compression ratio, language setting, volume, pitch, and equalization setting.

5. The method of claim 3, wherein the method further comprises the step of using at least one among the digital photograph and the audio sample as wallpaper on a display or as an alert or a ring tone.

6. A method for indicating a freshness of a picture used in a context aware application, comprising the steps of:

photographing an object;

associating a location indication representative of a location when the object was photographed; and

altering a picture quality of a photograph of the object over time to provide an indication of a freshness of the location indication.

7. The method of claim 6, wherein the step of photographing the object comprises the step of digitally photographing the object using an electronic device having a location sensor.

8. The method of claim 6, wherein the step of associating the location indication comprises the step of deriving a location indication using at least one among a GPS receiver, a triangulation technique, and a location identifier to provide an approximate location of the object photographed.

9. The method of claim 6, wherein method further comprises the step of obtaining a location fix before the step of associating the location indication.

10. The method of claim 6, wherein the method further comprises the step of time stamping the object photographed.

11. The method of claim 6, wherein the method further comprises the step of displaying the object photographed on a display.

12. The method of claim 6, wherein the step of altering the picture quality comprises the step of altering at least one among visual characteristics comprising contrast, brightness, sharpness, pixel resolution, vertical positioning, horizontal positioning, color setting, white balance, compression ratio, and language setting.

13. A system for indicating a freshness of data used in a context aware application, comprising:

a location device capable of receiving location information;

a recording device coupled to the location device for recording at least one among a video signal and an audio signal;

a presentation device coupled to the recording device for presenting at least one among the video signal and the audio signal; and

a processor coupled to the recording device, the presentation device and the location device, wherein the processor is programmed to;

associate a location indication with presentation data obtained at a location representative of the location indication; and

alter a data characteristic of the presentation data over time to provide an indication of a freshness of the location indication.

14. The system of claim 13, wherein the processor is further programmed to alter a data quality by altering at least one among visual characteristics comprising contrast, brightness, sharpness, pixel resolution, white balance, compression ratio, and language setting or by altering a data quality by altering at least one among audio characteristics comprising language setting, volume, pitch, and equalization setting.

15. The system of claim 13, wherein the recording device comprises at least one among an image recording device and a sound recording device.

16. The system of claim 13, wherein the recording device comprises at least one among a digital camera, a camera phone, a digital video camera and a video phone and the processor is further programmed to associate a location indication with an object photographed at a location representative of the location indication and alter a picture quality of the object photographed over time to provide an indication of a freshness of the location indication.

17. The system of claim 13, wherein the location device comprises at least one among a GPS receiver, a receiver using a triangulation technique, and receiver capable of receiving a location identifier.

18. The system of claim 16, wherein the system further comprises a presentation device selected among a display for displaying the object photographed and a speaker for providing an audio output.

19. The system of claim 13, wherein system further comprises a GPS receiver and the processor is further programmed to obtain a location fix before the processor associates the location indication with the presentation data.

20. The system of claim 13, wherein the recording device comprises at least one among a digital camera, a camera phone, a digital video camera, a video phone, an MP3 burner, a DVD burner, a CD burner, and a hard drive.
