Abstract

In embodiments of capacitive touch controls lockout, a computing device includes a touch-screen display for user interaction, and includes one or more capacitive touch controls for user selection as a device input to initiate a device action. The computing device also includes a lockout service that is implemented to disable one or more of the capacitive touch controls based on user interaction with the touch-screen display.

Claims

1. A computing device, comprising:

a touch-screen display configured for user interaction;

one or more capacitive touch controls configured for user selection as a device input to initiate a device action;

a touch input module configured to receive user inputs to the one or more capacitive touch controls;

a memory and a processor to implement a lockout service that is configured to;

receive various service inputs from the touch input module indicating a touch input and/or user interaction with the touch-screen display;

receive recognition of an inadvertent user contact with a capacitive touch control of the one or more capacitive touch controls;

receive a service input of the inadvertent user contact as a user slide input direction of approach towards the capacitive touch control, the user slide input direction of approach based on a touch signal sensed on a first side of the capacitive touch control and progressively passing over to a second side of the capacitive touch control; and

disable one or more of the capacitive touch controls based on the inadvertent user contact with the capacitive touch control to avoid an inadvertent actuation of the one or more capacitive touch controls.

2. A computing device as recited in claim 1, wherein the lockout service is configured to receive the service input of the user contact with the capacitive touch control.

3. A computing device as recited in claim 1, wherein the lockout service is configured to receive the service input of the inadvertent user contact as a user input on the touch-screen display adjacent to the capacitive touch control.

4. A computing device as recited in claim 1, wherein the lockout service is configured to receive the service input of the user contact as coordinated multiple user inputs on the touch-screen display.

5. A computing device as recited in claim 1, wherein the lockout service is further configured to re-enable one or more of the capacitive touch controls after a duration of time and no additional user interaction with the touch-screen display.

6. A computing device as recited in claim 1, wherein the lockout service is further configured to disable the one or more capacitive touch controls for a variable duration of time based on a position of the user interaction with the touch-screen display.

7. A computing device as recited in claim 1, wherein the lockout service is further configured to disable the one or more capacitive touch controls for a duration of time, after which one or more of the capacitive touch controls re-enable without input from the lockout service.

8. A computing device as recited in claim 1, wherein the lockout service is configured to receive an override input to re-enable the capacitive touch control that has been disabled, the override input received as a held user selection of the capacitive touch control for a duration of time.

9. A computing device as recited in claim 1, wherein the lockout service is further configured to disable a first capacitive touch control based on a user input to select a second capacitive touch control.

10. A computing device as recited in claim 1, wherein the lockout service is further configured to initiate active user feedback to indicate that the capacitive touch control has been disabled.

11. A computer-implemented method, comprising:

activating a touch-screen display for user interaction;

enabling one or more capacitive touch controls for user selection as a device input to initiate a device action;

receiving various service inputs that indicate a touch input and/or user interaction with the touch-screen display;

receiving recognition of an inadvertent user contact with a capacitive touch control of the one or more capacitive touch controls, the inadvertent user contact recognized as a user slide input direction of approach towards the capacitive touch control based on a touch signal sensed on a first side of the capacitive touch control and progressively passing over to a second side of the capacitive touch control;

distinguishing a user input to the capacitive touch control from the inadvertent user contact with the capacitive touch control; and

disabling one or more of the capacitive touch controls based on the inadvertent user contact with the capacitive touch control to avoid an inadvertent actuation of the one or more capacitive touch controls.

12. A computer-implemented method as recited in claim 11, further comprising receiving a service input based on at least one of:

the user input to the capacitive touch control;

the user contact on the touch-screen display adjacent to the capacitive touch control;

the inadvertent user contact as a user slide input direction of approach towards the capacitive touch control;

or

the user contact indicating coordinated multiple user inputs on the touch-screen display.

13. A computer-implemented method as recited in claim 11, further comprising re-enabling one or more of the capacitive touch controls after a duration of time and no additional user contact with the touch-screen display.

14. A computer-implemented method as recited in claim 11, wherein the one or more capacitive touch controls are disabled for a variable duration of time based on a position of the user interaction with the touch-screen display.

15. A computer-implemented method as recited in claim 11, wherein the one or more capacitive touch controls are disabled for a duration of time, after which the one or more capacitive touch controls re-enable without an activation input.

16. A computer-implemented method as recited in claim 11, further comprising receiving an override input to re-enable the capacitive touch control that has been disabled, the override input based on a held user selection of the capacitive touch control for a duration of time.

17. A computer-implemented method as recited in claim 11, wherein a first capacitive touch control is disabled based on a user input to select a second capacitive touch control.

18. A touch controls lockout system, comprising:

one or more capacitive touch controls configured for user selection as a device input to initiate a device action; and

a lockout service executable by a processor and configured to;

receive various service inputs that indicate a touch input and/or user interaction with a touch-screen display;

receive recognition of an inadvertent user contact with a capacitive touch control of the one or more capacitive touch controls;

distinguish a user input to the capacitive touch control from the inadvertent user contact with the capacitive touch control; and

disable one or more of the capacitive touch controls for a duration of time based on the inadvertent user contact with the capacitive touch control to avoid an inadvertent actuation of the one or more capacitive touch controls, the one or more capacitive touch controls configured to re-enable after the duration of time without an activation input.

19. A touch controls lockout system as recited in claim 18, wherein the lockout service is further configured to receive a service input based on at least one of:

the user input to the capacitive touch control;

the user contact on the touch-screen display adjacent to the capacitive touch control;

the user contact indicating coordinated multiple user inputs on the touch-screen display;

or

the inadvertent user contact as a user slide input direction of approach towards the capacitive touch control.
