Abstract

Detection of gesture data segmentation in mobile devices. An embodiment of a mobile device includes an edge, the edge including at least a first side, and a first touch sensor of one or more touch sensors, the first touch sensor being a side touch sensor to detect contact with the first side of the mobile device. The mobile device further includes one or more motion detection elements to generate motion data representing motion of the mobile device through space over a period of time, a buffer for the storage of the motion data, and a gesture recognition module to interpret the motion data stored in the buffer, wherein the mobile device begins the storage of the motion data in the buffer upon detection of a start of gesture data event, the start of gesture data event including contact with the first touch sensor.

Claims

1. A mobile device comprising:

an edge, the edge including at least a first side;

a first touch sensor of one or more touch sensors, the first touch sensor being a side touch sensor to detect contact with the first side of the mobile device;

one or more motion detection elements to generate motion data representing motion of the mobile device through space over a period of time;

a buffer for the storage of the motion data; and

a gesture recognition module to interpret the motion data stored in the buffer;

wherein the mobile device begins the storage of the motion data in the buffer upon detection of a start of gesture data event, the start of gesture data event including contact with the first touch sensor.

2. The mobile device of claim 1, wherein the start of gesture data event includes a contact of a thumb or other finger of a user with the first touch sensor.

3. The mobile device of claim 2, wherein the start of gesture data event further includes a contact of one or more other fingers of the user with a second touch sensor, the second touch sensor detecting contact with a second side of the mobile device.

4. The mobile device of claim 3, wherein the second side is an opposite side to the first side.

5. The mobile device of claim 2, wherein the mobile device ends the storage of motion data upon the detection of an end of gesture data event.

6. The mobile device of claim 5, wherein the end of gesture data event includes ceasing the contact with the first touch sensor.

7. The mobile device of claim 5, wherein the end of gesture data event includes a gesture performed by a user on or across the first touch sensor.

8. The mobile device of claim 1, further comprising a clock element to determine the passage of time, wherein the mobile device utilizes a passage of time determined by the clock element to establish a time out condition to end collection of motion data.

9. The mobile device of claim 1, further comprising a motion detection module, the motion detection module to determine whether the motion data in the buffer is indicative of a motion for a gesture, and, if so, to trigger operation of the gesture recognition module.

10. The mobile device of claim 1, wherein the one or more motion detection elements includes one or more of an accelerometer element and a gyroscope element.

11. A method comprising:

detecting a start of gesture data event for a mobile device, the mobile device including a first touch sensor, the start of gesture data event including contact with the first touch sensor;

collecting motion data generated by one or more motion detection elements of the mobile device;

storing the collected motion data in a buffer; and

interpreting the motion data stored in the buffer using a gesture detection module.

12. The method of claim 11, wherein the start of gesture data event includes a contact of a thumb or other finger of a user with the first touch sensor.

13. The method of claim 12, wherein the start of gesture data event further includes a contact of one or more other fingers of the user with a second touch sensor of the mobile device.

14. The method of claim 11, further comprising ending the storage of motion data upon the detection of an end of gesture data event.

15. The method of claim 14, wherein the end of gesture data event includes ceasing the contact with the first touch sensor.

16. The method of claim 14, wherein the end of gesture data event includes a gesture performed by a user on or across the first touch sensor.

17. The method of claim 11, further comprising measuring a passage of time and establishing a time out condition to end collection of motion data if the passage of time is greater than a predetermined length of time.

18. The method of claim 11, further determining whether the motion data in the buffer is indicative of a motion for a gesture using a motion detection algorithm, and, if so, commencing the interpretation of the motion data.

19. A system comprising:

a touch sensor to detect contact of a user with the touch sensor;

an accelerometer to detect acceleration of the system and a gyroscope to detect rotation of the system, the accelerometer and gyroscope to generate motion data;

a buffer for storage of the motion data generated by the accelerometer and gyroscope; and

a gesture recognition module to interpret the motion data stored in the buffer;

wherein the system begins the storage of the motion data in the buffer upon detection of a start of gesture data event, the start of gesture data event including contact of the user with the touch sensor.

20. The system of claim 19, wherein the start of gesture data event includes a contact of a thumb or other finger of a user with the touch sensor.

21. The system of claim 20, wherein the start of gesture data event further includes a contact of one or more other fingers of the user with a second touch sensor.

22. The system of claim 19, wherein the system ends the storage of motion data upon the detection of an end of gesture data event.

23. The system of claim 22, wherein the end of gesture data event includes either ceasing the contact with the touch sensor or a gesture performed by a user on or across the first touch sensor

25. The system of claim 19, further comprising a motion detection module, the motion detection module to determine whether the motion data in the buffer is indicative of a motion for a gesture, and, if so, to trigger operation of the gesture recognition module.

26. A non-transitory computer-readable medium having stored thereon data representing sequences of instructions that, when executed by a processor, cause the processor to perform operations comprising:

detecting a start of gesture data event for a mobile device, the mobile device including a first touch sensor, the start of gesture data event including contact with the first touch sensor;

collecting motion data generated by one or more motion detection elements of the mobile device;

storing the collected motion data in a buffer; and
