Abstract

A user interface, an apparatus and method for gesture recognition comprising: predicting one or more possible commands to the apparatus based on one or more sub gestures performed by a user previously; indicating the one or more possible commands.

Claims

1. A user interface in a gesture recognition system comprising:

a display window adapted to indicate a following sub gesture of at least one gesture command, according to at least one sub gesture and an order of the at least one sub gesture previously conducted by a user and recognized by the gesture recognition system.

2. The user interface according to claim 1, wherein the following sub gesture is indicated by a hint along with information on how to perform the following gesture to complete the at least one gesture command.

3. The user interface according to claim 2, wherein an indication of at least one sub gesture recognized by the gesture recognition system is also shown at a corresponding location to the hint in the display window,

4. The user interface according to claim 1, wherein when the following sub gesture of one gesture command is being conducted by the user and recognized by the gesture recognition system, the following sub gestures of other gesture commands will disappear in the display window.

5. The user interface according to claim 4, wherein the display window with the hint and the indication of at least one sub gesture has an opacity, which is decreased gradually when the following sub gesture is being conducted by the user and recognized by the gesture recognition system.

6. The user interface according to claim 1, wherein the following sub gesture is determined by using the recognized at least one sub gesture and the order of the at least one sub gesture to search in a database, wherein the database comprises gesture definition of the at least one gesture command, each gesture command comprises at least one sub gesture in a predefined order,

7. An apparatus comprising:

a gesture predicting unit adapted to predict one or more possible commands to the apparatus based on one or more sub gestures and an order of the one or more sub gestures previously performed by a user and recognized by the apparatus;

a display adapted to indicate a following sub gesture of the one or more possible commands in an user interface.

8. The apparatus according to claim 7, wherein the following sub gesture is indicated in the user interface by a hint along with information on how to perform the following gesture to complete the commands,

9. The apparatus according to claim 7, wherein display is also adapted to indicate the one or more sub gesture recognized by the apparatus.

10. The apparatus according to claim 7, wherein when the following sub gesture of one possible command is being conducted by the user and recognized by the apparatus, the following sub gestures of other possible commands will disappear in the user interface.

11. The apparatus according to claim 7, wherein the one or more possible commands are predicted by using the recognized one or more sub gestures and the order of the one or more sub gestures, to search in a database, wherein the database comprises gesture definition of the at least one gesture command, each gesture command comprises at least one sub gesture in a predefined order.

12. A method for gesture recognition in an apparatus comprising:

predicting one or more possible commands to the apparatus based on one or more sub gestures and an order of the one or more sub gestures recognized by the apparatus previously;

indicating a following sub gesture of the one or more possible commands by an user interface.

13. The method according to claim 12, wherein the following sub gesture is indicated by a hint shown in the user interface, and an indication of the one or more sub gesture performed by the user is also shown in the user interface,

14. The method according to claim 12, wherein the one or more possible commands are predicted by using the recognized one or more sub gestures and the order of the one or more sub gestures to search in a database, wherein the database comprises gesture definition of the at least one gesture command, each gesture command comprises at least one sub gesture in a predefined order.

15. The method according to claim 12, wherein the hints are shown along with information on how to perform the following sub gesture to complete the at least one command.
