Abstract

With the addition of directional information in the environment, a variety of service(s) can be provided on top of user identification or interaction with specific object(s) of interest by pointing at the objects. Sometimes either the device user and/or the publishers of content cannot complete a content exchange associated with a point of interest (POI) fast enough for the content to remain relevant. Thus, POIs and content for POIs can be predicted for users based on a variety of factors, such as an analysis of their present path and directional changes, rates of changes, or other factors, such that there is no noticeable, or minimal, latency between information being available with respect to such POIs and a request made via the user'"'"'s device for such POI information.

Claims

1. A method for displaying point of interest information on a mobile device, comprising:

determining direction information as a function of a direction for the device;

determining position information as a function of a position for the device;

predicting a set of points of interest for future interaction based on the direction information and the position information; and

receiving, in a local memory of the device, point of interest information for at least a subset of the points of interest of the set based on a probability of a future interaction with at least the subset of the points of interest.

2. The method of claim 1, further comprising:

determining motion information as a function of movement of the device; and

the predicting includes predicting based on the direction information, the position information and the motion information.

3. The method of claim 1, further comprising:

transmitting at least one identifier associated with the points of interest of the set to a network service enabling information about the points of interest to be received according to the receiving.

4. The method of claim 1, wherein the predicting includes receiving explicit input with respect to the one or more POIs to be included in the set.

5. The method of claim 1, wherein the predicting includes receiving at least one of a gesture input, a keyword input, an audio input, a video camera input or a touchscreen input with respect to one or more POIs to be included in the set.

6. The method of claim 1, wherein the predicting includes receiving implicit input with respect to the one or more POIs to be included in the set.

7. The method of claim 1, wherein the receiving includes receiving the point of interest information in a local cache memory of the device.

8. The method of claim 1, wherein the predicting includes predicting based on at least one pre-defined criterion explicitly or implicitly defining the points of interest of the set.

9. The method of claim 8, wherein the predicting includes predicting based on points of interest within a current path of the device based on device path history.

10. The method of claim 8, wherein the predicting includes predicting the points of interest of the set based on a time of day.

11. The method of claim 1, wherein the predicting includes designating the points of interest of the set including receiving touchscreen input relating to the points of interest of the set.

13. The device of claim 11, wherein the at least one processor is further configured to transmit the at least one identifier of the at least one the point of interest to at least one network service to pre-fetch the advertisement information.

14. The device of claim 11, further comprising:

a pointer that visually indicates the orientation of the portable electronic device based upon which the directional component outputs the direction information.

15. The device of claim 11, further comprising:

at least one audio device for rendering audio content of the advertisement information if a condition upon which the predicted interaction is predicated occurs.

16. The device of claim 11, wherein the directional component is a digital compass that outputs the direction information.

17. The device of claim 11, wherein the at least one processor is configured to process the position information and the direction information to determine a pointing line and to determine the at least one identifier as a subset of a plurality of identifiers of points of interest that substantially intersect with an area defined as a function of the pointing line.

18. The device of claim 16, wherein the at least one processor is configured to process the position information and the direction information to determine a pointing line and to determine the at least one identifier as a subset of the plurality of identifiers of points of interest that substantially intersect with at least one of an arc function defining an arc based on an angle with respect to the pointing line, a conical function defining a cone based on an angle with respect to the pointing line, or a line function defining a rectangular space oriented along the pointing line.

20. The method of claim 1, further comprising:

determining motion information as a function of movement of the device; and

the aging out including aging out based on the direction information, the position information and the motion information.

12. A portable electronic device, comprising:

a memory storing at least information related to at least one point of interest;

a positional component for receiving position information as a function of a location of the portable electronic device;

a directional component that outputs direction information as a function of an orientation of the portable electronic device; and

at least one processor configured to process the position information and the direction information to determine at least one identifier of at least one point of interest within a predicted scope of the device, to pre-fetch advertisement information corresponding to the at least one identifier of the at least one point of interest, and to display the pre-fetched advertisement information if the device interacts with the at least one point of interest with the device.

19. A method for displaying point of interest information on a mobile device, comprising:

determining direction information based on an orientation for the device;

determining position information as a function of a position for the device;

identifying a region of real space that the device is unlikely to encounter in the future based on the direction information and the position information; and

aging out, from a local cache of the device, point of interest information for a set of points of interest in the region that the device is unlikely to encounter.
