Abstract

Mobile device rejection of unintentional sensor contact. An embodiment of a mobile device includes a first touch sensor to detect contact by a user of the mobile device for input of gestures by the user, a memory to store indicators of unintentional contact to the first touch sensor, and a processor to evaluate contact to the first touch sensor. The processor compares a contact with the first touch sensor to the indicators of unintentional contact to determine if the contact is unintentional, and the mobile device rejects the contact as an input to the mobile device if the contact is determined to be unintentional and accepts the contact as an input to the mobile device if the contact is determined to be intentional.

Claims

1. A computing device capable of being used in distinguishing between intentional touch contacts and unintentional contacts, the computing device comprising:

a touch screen located on a top side of the computing device;

a side touch sensor located on a side of the computing device different from the top side;

a processor; and

storage capable of storing instructions to be executed by the processor, the instructions when executed by the processor being capable of resulting in performance of operations comprising;

detection, by the side touch sensor, of a touch of a user;

analyzing of data relating to the touch detected by the side touch sensor to determine whether the touch is intentional or unintentional, wherein analyzing includes comparing the data relating to the touch to a plurality of indicators obtained over a period of time;

acceptance of the touch, if one or more indicators of the plurality of indicators identify the touch to be intentional; and

rejection of the touch, if one or more indicators identify the touch to be unintentional.

2. The computing device of claim 1, wherein the side touch sensor is further to detect simultaneous multiple touches of the user, wherein at least a first touch of the multiple touches is identified as intentional, and wherein at least a second touch of the multiple touches is identified as unintentional, wherein the second touch is identified as being unintentional for having potential for causing disruption in usage experience of the user.

3. The computing device of claim 1, wherein the acceptance of the touch detected by the side touch sensor comprises responding to an input associated with the touch, wherein the rejection of the touch comprises ignoring of the input associated with the touch, and wherein the data includes the input, wherein the data comprises at least one of size of the touch, shape of the touch, motion of the touch, or contact points relating to the touch.

4. The computing device of claim 3, wherein the touch detected by the side touch sensor is unintentional if the size, when comparing with one or more indicators, indicates the touch being facilitated by a hand or a palm of the user.

5. The computing device of claim 3, wherein the touch detected by the side touch sensor is unintentional if the shape, when comparing with the one or more indicators, indicates the touch being facilitated by a hand or a palm of the user.

6. The computing device of claim 3, wherein the touch detected by the side touch sensor is unintentional if the motion, when comparing with one or more indicators, indicates the touch being facilitated by a resting hand or a resting palm of the user.

7. The computing device of claim 3, wherein the touch detected by the side touch sensor is unintentional if the contact points, when comparing with the one or more indicators, indicate the touch being made in one or more non-contact areas near the touch sensor.

8. A method for distinguishing between intentional touch contacts and unintentional touch contacts, the method comprising:

detecting, by a side touch sensor located on a side of a computing device and different from a top side of the computing device, a touch of a user;

analyzing data relating to the touch detected by the side touch sensor to determine whether the touch is intentional or unintentional, wherein analyzing includes comparing the data relating to the touch to a plurality of indicators obtained over a period of time;

accepting the touch, if one or more indicators of the plurality of indicators identify the touch to be intentional; and

rejecting the touch, if the one or more indicators identify the touch to be unintentional.

9. The method of claim 8, further comprising detecting, by the side touch sensor, simultaneous multiple touches of the user, wherein at least a first touch of the multiple touches is identified as intentional, and wherein at least a second touch of the multiple touches is identified as unintentional, wherein the second touch is identified as being unintentional for having potential for causing disruption in usage experience of the user.

10. The method of claim 8, wherein accepting the touch detected by the side touch sensor comprises responding to an input associated with the touch, wherein rejecting the touch comprises ignoring the input associated with the touch, wherein rejecting the touch comprises ignoring the input associated with the touch, and wherein the data includes input, wherein the data comprises at least one of size of the touch, shape of the touch, motion of the touch, or contact points relating to the touch.

11. The method of claim 10, wherein the touch detected by the side touch sensor is unintentional if the size when comparing with the one or more indicators, indicates the touch being facilitated by a hand or a palm of the user.

12. The method of claim 10, wherein the touch detected by the side touch sensor is unintentional if the shape, when comparing with the one or more indicators, indicates the touch being facilitated by a hand or a palm of the user.

13. The method of claim 10, wherein the touch detected by the side touch sensor is unintentional if the motion, when comparing with the one or more indicators, indicates the touch being facilitated by a resting hand or a resting palm of the user.

14. The method of claim 10, wherein the touch detected by the side touch sensor is unintentional if the contact points, when comparing with the one or more indicators, indicate the touch being made in one or more non-contact areas near the touch sensor.

15. A machine-readable medium comprising instructions which, when executed by a computing device, cause the computing device to perform operations comprising:

detecting, by a side touch sensor located on a side of the computing device different from a top side of the computing device, a touch of a user;

analyzing data relating to the touch detected by the side touch sensor to determine whether the touch is intentional or unintentional, wherein analyzing includes comparing the data relating to the touch to a plurality of indicators obtained over a period of time;

accepting the touch, if one or more indicators of the plurality of indicators identify the touch to be intentional; and

rejecting the touch, if one or more indicators identify the touch to be unintentional.

16. The machine-readable medium of claim 15, wherein the operations further comprise detecting, by the side touch sensor, simultaneous multiple touches of the user, wherein at least a first touch of the multiple touches is identified as intentional, and wherein at least a second touch of the multiple touches is identified as unintentional, wherein the second touch is identified as being unintentional for having potential for causing disruption in usage experience of the user.

17. The machine-readable medium of claim 15, wherein accepting the touch detected by the side touch sensor comprises responding to an input associated with the touch, wherein rejecting the touch comprises ignoring the input associated with the touch, and wherein the data includes the input, wherein the data comprises at least one of size of the touch, shape of the touch, motion of the touch, or contact points relating to the touch.

18. The machine-readable medium of claim 17, wherein the touch detected by the side touch sensor is unintentional if the size, when comparing with the one or more indicators, indicates the touch being facilitated by a hand or a palm of the user.

19. The machine-readable medium of claim 17, wherein the touch detected by the side touch sensor is unintentional if the shape, when comparing with the one or more indicators, indicates the touch being facilitated by a hand or a palm of the user.

20. The machine-readable medium of claim 17, wherein the touch detected by the side touch sensor is unintentional if the motion, when comparing with the one or more indicators, indicates the touch being facilitated by a resting hand or a resting palm of the user,

wherein the touch is unintentional if the contact points, when comparing with the one or more indicators, indicate the touch being made in one or more non-contact areas near the touch sensor.
