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.

First claim

What is claimed is:

1. A mobile device comprising:
a side touch sensor to detect a contact with the side touch sensor over a time period performed by a user of the mobile device, wherein the side touch sensor is a capacitive touch sensor to detect contact with a side of the mobile device for input of gestures by the user;
a memory to store indicators of unintentional contact to the touch sensor; and
a processor to evaluate contact to the side touch sensor,
wherein the processor is to compare the contact with the side touch sensor over the time period to the indicators of unintentional contact to determine if the contact is intended to be a gesture input or if the contact is unintentional, wherein the comparison includes performance of a statistical analysis of the contact with the side touch sensor over the time period, the statistical analysis including analysis of shape and movement characteristics of the contact;
wherein the indicators of unintentional contact include data regarding motion of contact areas on the side touch sensor over the time period, and
wherein the mobile device is to reject the contact to the side touch sensor as a gesture input to the mobile device if the contact is determined to be unintentional based on the comparison of the contact to the indicators of unintentional contact and to accept the contact as a gesture input to the mobile device if the contact is determined to be intentional.

2. The mobile device of claim 1 , wherein the indicators of unintentional contact are developed by empirical study of mobile device usage.

3. The mobile device of claim 1 , wherein the indicators of unintentional contact further include data regarding contact shape on the side touch sensor.

4. The mobile device of claim 3 , wherein the data regarding contact shape on the side touch sensor includes data describing a shape of a hand supporting the mobile device in a resting position.

5. The mobile device of claim 1 , wherein the indicators of unintentional contact further include data regarding size of a contact area for the contact on the side touch sensor.

6. The mobile device of claim 1 , wherein the indicators of unintentional contact further include data regarding a number of contact areas on the side touch sensor.

7. The mobile device of claim 6 , wherein the data regarding a number of contact areas includes an indicator of multiple contact areas on the side touch sensor resulting for a user holding a mobile device in a hand while contacting the side touch sensor with a thumb or other finger of the hand.

8. The mobile device of claim 1 , wherein the data regarding motion of contact areas on the side touch sensor over the time period includes data regarding a stationary contact area for a mobile device supported in a user hand.

9. A method comprising:
detecting a contact over a time period with a side touch sensor of a mobile device, the side touch sensor providing for input of gestures by a user of the mobile device, wherein the side touch sensor is a capacitive touch sensor to detect contact with a side of the mobile device;
comparing the contact with the side touch sensor over the time period with indicators of unintentional contact with the mobile device, wherein the comparison includes performance of a statistical analysis of the contact with the side touch sensor over the time period, the statistical analysis including analysis of shape and movement characteristics of the contact, wherein the indicators of unintentional contact include data regarding motion of contact areas on the side touch sensor over the time period;
if the comparison of the contact to the side touch sensor with the indicators of unintentional contact indicates that the contact is unintentional, rejecting the contact as a gesture input to the mobile device; and
if the comparison of the contact with the indicators of unintentional contact indicates that the contact is intentional, accepting the contact as a gesture input to the mobile device.

10. The method of claim 9 , wherein the indicators of unintentional contact are developed by empirical study of mobile device usage.

11. The method of claim 9 , wherein the indicators of unintentional contact further include data regarding contact shape on the side touch sensor.

12. The method of claim 11 , wherein the data regarding contact shape on the side touch sensor includes data describing a shape of a hand supporting the mobile device in a resting position.

13. The method of claim 9 , wherein the indicators of unintentional contact further include data regarding size of a contact area for the contact on the side touch sensor.

14. The method of claim 9 , wherein the indicators of unintentional contact further include data regarding a number of contact areas on the side touch sensor.

15. The method of claim 14 , wherein the data regarding a number of contact areas includes an indicator of multiple contact areas on the side touch sensor resulting for a user holding a mobile device in a hand while contacting the side touch sensor with a thumb or other finger of the hand.

16. The method of claim 9 , wherein the data regarding motion of contact areas on the side touch sensor over the time period includes data regarding a stationary contact area for a mobile device supported in a user hand.

17. A mobile system comprising:
a side touch sensor to detect a contact with the side touch sensor over a time period performed by a user with a side of the system, wherein the side touch sensor is a capacitive touch sensor to detect contact with a side of the mobile system for input of gestures by the user;
a flash memory to store indicators of unintentional contact to the side touch sensor; and
a processor to evaluate contact to the side touch sensor;
wherein the processor is to compare the contact with the side touch sensor over the time period to the indicators of unintentional contact to determine if the contact is intended to be a gesture input or if the contact is unintentional, wherein the comparison includes performance of a statistical analysis of the contact with the side touch sensor over the time period, the statistical analysis including analysis of shape and movement characteristics of the contact;
wherein the indicators of unintentional contact include data regarding motion of contact areas on the side touch sensor over the time period; and
wherein the mobile system is to reject the contact to the side touch sensor as a gesture input to the system if the contact is determined to be unintentional based on the comparison of the contact to the indicators of unintentional contact and to accept the contact as a gesture input to the system if the contact is determined to be intentional.

18. The system of claim 17 , wherein the indicators of unintentional contact include data regarding one or more of contact shape, size of contact area, and number of contact areas on the side touch sensor.

19. The system of claim 18 , wherein the data regarding contact shape on the side touch sensor includes data describing a shape of a hand supporting the system in a resting position.

20. The system of claim 18 , wherein data regarding a number of contact areas includes an indicator of multiple contact areas on the side touch sensor resulting for a user holding the system in a hand while contacting the side touch sensor with a thumb or other finger of the hand.

21. A non-transitory computer-readable medium having stored thereon data representing sequences of instructions that, when exec
