Abstract

The invention is a system and method for computing a result for a location, wherein the result indicates how novel it is for a wireless device to occupy a specific location. After determining the location of a wireless device through various means, a Novelty Index Value (NIV) is calculated for the location, and the NIV is then stored into a database. The NIV may then be subsequently used by application programs to compute a desired result from the NIV. Multiple users may utilize and/or share the same NIV values. The NIV may also be used to alter the configuration of a wireless device as well. A recommendation system is also disclosed, wherein user context is utilized along with NIV values to compute particular results for a user.

Claims

1. A method comprising:

computing a novelty index value for a wireless device for a plurality of locations, the novelty index value computed from a measure of probability of a device occupying each of the plurality of locations;

storing the novelty index value in a database for each of the plurality of locations;

determining a location of the wireless device;

running a program to determine a result that depends on the novelty index value;

accessing the database for information associated with the novelty index value; and

computing a result for the location using said information,

wherein the step of determining further comprises determining the location of the wireless device by a global positioning system detector, by a triangulation of mobile phone base stations, or by proximity to a short-range communications device.

2. The method of claim 1, wherein the step of computing a novelty index value further comprises computing a magnitude for the novelty index value proportional to how unusual it is for the wireless device to occupy the location.

3. The method of claim 1, wherein the step of computing a novelty index value further comprises computing a magnitude for the novelty index value which increases as the duration of time since the wireless device has occupied the location.

4. The method of claim 1, wherein the step of computing a novelty index value further comprises computing a magnitude for the novelty index value which decreases when the wireless device occupies the location.

5. The method of claim 1, wherein the step of computing a novelty index value further comprises computing in the wireless device.

6. The method of claim 1, wherein the step of computing a novelty index value further comprises computing in a separate server coupled to the wireless device.

7. The method of claim 1, wherein the step of storing further comprises storing in the wireless device.

8. The method of claim 1, wherein the step of storing further comprises storing in a separate server coupled to the wireless device.

9. The method of claim 1, wherein the step of running a program further comprises running the program in the wireless device.

10. The method of claim 1, wherein the step of running a program further comprises running the program in a separate server coupled to the wireless device.

11. The method of claim 1, wherein the step of running a program further comprises determining a result for a game program, a shopping discount program, or a lost child tracking program.

12. The method of claim 1, wherein the step of accessing a database further comprises accessing a location corresponding to a requested range of novelty index values.

13. The method of claim 1, wherein the step of accessing a database further comprises accessing a novelty index value corresponding to a requested range of location values.

14. The method of claim 1, wherein the step of computing the result further comprises computing the result in the wireless device.

15. The method of claim 1, wherein the step of computing the result further comprises computing the result in a separate server coupled to the wireless device.

16. The method of claim 1, wherein the step of running a program further comprises determining a result for an e-commerce program, a sports results program, a stock quotes program, a weather forecast program, or an online travel program.

17. The method of claim 1, wherein the step of computing the result further comprises downloading distinctive ringing tones, exchanging multimedia messages that combine text with photographic content, exchanging multimedia messages that combine text with image content, exchanging multimedia messages that combine text with voice clip content, exchanging multimedia messages, paying bills online, delivering useful and informative advertising, conducting transaction services from online merchants, or providing entertainment services.

18. The method of claim 1, wherein the step of computing the result further comprises providing recommendations to the user of the wireless device for the location according to said information.

19. The method of claim 1, wherein the step of computing the result further comprises changing a configuration of the wireless device for the location according to said information.

20. A system comprising:

a processor;

a memory coupled to the processor, programmed to perform the steps of;
