Abstract

A processing device is configured to provide a user interface comprising a radial layout soft keypad. The radial layout soft keypad comprises a central region and one or more concentric groupings of keys arranged around the central region. For example, the one or more concentric groupings of keys may be arranged as multiple concentric circular rows of keys substantially surrounding the central region, with all of the keys of the concentric circular rows being simultaneously visible in the radial layout soft keypad. The radial layout soft keypad is illustratively presented on a display associated with the processing device and a user interacts with the radial layout soft keypad by making hand gestures in free space in a field of view of an image sensor. A gesture of a first type controls selection of a key and gestures of second and third types control acceptance and rejection of the selected key.

Claims

1. An apparatus comprising:

at least one processing device comprising a processor coupled to a memory;

said at least one processing device being configured to provide a user interface comprising a radial layout soft keypad;

wherein the radial layout soft keypad comprises a central region and one or more concentric groupings of keys arranged around the central region.

2. The apparatus of claim 1 wherein the one or more concentric groupings of keys are arranged as respective concentric circular rows of keys substantially surrounding the central region.

3. The apparatus of claim 1 wherein all of the keys of the one or more concentric groupings of keys are simultaneously visible in the radial layout soft keypad.

4. The apparatus of claim 1 wherein the radial layout soft keypad is presented on a display associated with the processing device and a user interacts with the radial layout soft keypad by making hand gestures in free space in a field of view of an image sensor without physically contacting the display.

5. The apparatus of claim 4 wherein a gesture of a first type controls selection of a given one of the keys and gestures of respective second and third types control respective acceptance and rejection of the selected key.

6. The apparatus of claim 5 wherein upon detection of the gesture of the first type the corresponding selected key is presented in a highlighted form in which an additional instance of the selected key is generated and partially overlaid in an offset manner over an initial instance of the selected key.

7. The apparatus of claim 4 wherein a gesture controlling acceptance of a selected key and a gesture controlling rejection of a selected key are detected based on motion characteristics in a plane substantially parallel to a plane of the display without requiring additional motion along an axis orthogonal to the plane of the display.

8. The apparatus of claim 1 wherein detection of a gesture directing inward movement of a selected key toward the central region indicates acceptance of the selected key and detection of a gesture directing outward movement of the selected key away from the central region indicates rejection of the selected key.

9. The apparatus of claim 8 wherein the gestures directing respective inward and outward movement of the selected key towards and away from the central region comprise respective flick gestures.

10. The apparatus of claim 1 wherein the radial layout soft keypad comprises an inner boundary separating the central region from the one or more concentric groupings of keys and an outer boundary separating the one or more concentric groupings of keys from a peripheral region of the radial layout soft keypad.

11. The apparatus of claim 10 wherein at least one of the inner and outer boundaries is visually perceptible to a user when viewing the radial layout soft keypad as presented on a display.

12. The apparatus of claim 10 wherein detection of a gesture directing inward movement of a selected key over the inner boundary and into the central region indicates acceptance of the selected key.

13. The apparatus of claim 10 wherein detection of a gesture directing outward movement of a selected key over the outer boundary and into the peripheral region indicates rejection of the selected key.

14. The apparatus of claim 1 wherein the radial layout soft keypad further comprises a peripheral region in which one or more predicted words based on previous selected key acceptances by the user are presented for possible user selection and wherein acceptance of a selected one of the one or more predicted words is controlled based on detection of a gesture directing inward movement of the selected word toward the central region.

15. The apparatus of claim 1 wherein said at least one processing device comprises a computer and an associated image sensor.

16. An information processing system comprising the apparatus of claim 1.

17. A method comprising:

generating a user interface comprising a radial layout soft keypad; and

processing user input to control actuation of particular keys of the radial layout soft keypad;

wherein the radial layout soft keypad comprises a central region and one or more concentric groupings of keys arranged around the central region; and

wherein the method is implemented in at least one processing device comprising a processor coupled to a memory.

18. The method of claim 17 further comprising:

presenting the radial layout soft keypad on a display associated with the processing device; and

detecting the user input in the form of hand gestures made in free space in a field of view of an image sensor without physically contacting the display.

19. The method of claim 18 wherein a gesture of a first type controls selection of a given one of the keys and gestures of respective second and third types control respective acceptance and rejection of the selected key.

20. An article of manufacture comprising a computer-readable storage medium having computer program code embodied therein, wherein the computer program code when executed in at least one processing device causes the processing device to perform the method of claim 17.

21. A method comprising:

providing a user interface comprising a plurality of keys; and

processing user input comprising one or more gestures to control actuation of a selected one of said keys;

wherein detection of a first gesture directing movement of the selected key in a first direction indicates acceptance of the selected key;

wherein detection of a second gesture directing movement of the selected key in a second direction different than the first direction indicates rejection of the selected key; and

wherein the method is implemented in at least one processing device comprising a processor coupled to a memory.

22. The method of claim 21 wherein the first and second gestures comprise respective first and second flick gestures,
