Abstract

An alphanumeric information entry process that includes provision and use of a personal context model that correlates various examples of user context against a unique personal language model for the user. The personal language model itself along with considerable correlation examples can be developed by statistical analysis of user documents and files including particularly email files (including address books). Such processing can be done locally or remotely. The personal context model is used to predict subsequent alphanumeric entries for a given user. In one embodiment predictions are presented one word at a time. Predictions can be automatically changed in one embodiment when the user fails to make any input for a predetermined period of time.

Claims

1. A method comprising:

receiving first data from a user representing alphanumeric information;

predicting at least one additional item of alphanumeric information based at least in part on the first data;

presenting the at least one additional item of alphanumeric information to the user to provide presented candidate information;

automatically characterizing the presented candidate information as being unaccepted by the user without benefit of a detected bio-sourced physical indicator from the user.

2. The method of claim 1 wherein receiving first data from a user further comprises receiving first data from a user via at least one of:

a keypad key assertion;

tactile script input;

audio waves;

electromagnetic biological signals.

3. The method of claim 1 wherein predicting at least one additional item of alphanumeric information further comprises predicting at least one additional item of alphanumeric information based, at least in part, upon a personal context model as corresponds to the user.

4. The method of claim 1 wherein automatically characterizing the presented candidate information as being accepted by the user without benefit of a detected bio-sourced physical indicator from the user further comprises automatically characterizing the presented candidate information as being accepted by the user when no subsequent bio-sourced physical indicator is detected from the user within a predetermined amount of time.

5. The method of claim 4 wherein automatically characterizing the presented candidate information as being accepted by the user when no subsequent bio-sourced physical indicator is detected from the user within a predetermined amount of time further comprises automatically characterizing the presented candidate information as being accepted by the user when no subsequent bio-sourced physical indicator is detected from the user within a predetermined amount of time of when the presented candidate information is presented to the user.

6. The method of claim 4 and further comprising providing a set value for the predetermined amount of time.

7. The method of claim 4 and further comprising dynamically setting the predetermined amount of time.

8. The method of claim 7 wherein dynamically setting the predetermined amount of time further comprises dynamically setting the predetermined amount of time as a function, at least in part, of observed experience with respect to the user.

9. The method of claim 8 wherein dynamically setting the predetermined amount of time as a function, at least in part, of observed experience with respect to the user further comprises dynamically setting the predetermined amount of time as a function, at least in part, of observed experience with respect to how long it often takes the user to respond to an inaccurate prediction with a detectable bio-sourced physical indicator.

10. The method of claim 1 and further comprising:

automatically characterizing the presented candidate information as being accepted by the user upon detecting a particular bio-sourced physical indicator from the user.

11. The method of claim 1 and further comprising:

automatically replacing the presented candidate information with a different item of presented alphanumeric information in response to automatically characterizing the presented candidate information as being unaccepted by the user without benefit of a detected bio-sourced physical indicator from the user.

12. The method of claim 11 wherein receiving first data from a user further comprises receiving first data from a user via at least one of:

a keypad key assertion;

tactile script input;

audio waves;

electromagnetic biological signals.

13. The method of claim 11 wherein predicting at least one additional item of alphanumeric information further comprises predicting at least one additional item of alphanumeric information based, at least in part, upon a personal context model as corresponds to the user.

14. The method of claim 11 wherein adding the at least one additional item of alphanumeric information to a display that is already presenting previously presented and user-accepted predicted items of alphanumeric information wherein the at least one additional item of alphanumeric information is presented using a different visual appearance than is used for the previously presented and user-accepted predicted items of alphanumeric information further comprises using highlighting to present the at least one additional item of alphanumeric information.

15. The method of claim 14 wherein adding the at least one additional item of alphanumeric information to a display that is already presenting previously presented and user-accepted predicted items of alphanumeric information wherein the at least one additional item of alphanumeric information is presented using a different visual appearance than is used for the previously presented and user-accepted predicted items of alphanumeric information further comprises not using highlighting to present the previously presented and user-accepted predicted items of alphanumeric information.

16. The method of claim 11 and further comprising:

detecting user acceptance of the at least one additional item of alphanumeric information.

17. The method of claim 16 wherein detecting user acceptance of the at least one additional item of alphanumeric information further comprises detecting bio-sourced physical indicator from the user.

18. The method of claim 16 and further comprising:

in response to detecting user acceptance of the at least one additional item of alphanumeric information, automatically presenting the at least one additional item of alphanumeric information using a substantially same visual appearance as is used for the previously presented and user-accepted predicted items of alphanumeric information.

11-1. A method comprising:

receiving data from a user representing alphanumeric information;

predicting at least one additional item of alphanumeric information based at least in part on the data;

adding the at least one additional item of alphanumeric information to a display that is already presenting previously presented and user-accepted predicted items of alphanumeric information wherein the at least one additional item of alphanumeric information is presented using a different visual appearance than is used for the previously presented and user-accepted predicted items of alphanumeric information.

19. A method comprising:

receiving first data from a user representing alphanumeric information;

predicting at least one additional item of alphanumeric information based at least in part on the first data;

presenting the at least one additional item of alphanumeric information to the user to provide presented candidate information;

detecting a specific user input event;

in response to detection of the specific user input event, automatically characterizing the presented candidate information as being accepted by the user.

20. The method of claim 19 wherein detecting a specific user input event further comprises detecting an explicit user action.

21. The method of claim 20 wherein detecting an explicit user action further comprises detecting a bio-sourced physical indicator from the user.
