Abstract

Provided herein are a method, apparatus and computer program product for interpreting user input and mitigating erroneous inputs on a device. In particular, methods may include receiving an indication of a first touch event, determining, by a touch mediation function, if the first touch event is an erroneous touch event, causing the first touch event to be sent to an application in response to the touch mediation function determining that the touch event is not erroneous; and causing the first touch event to not be sent to the application in response to the touch mediation function determining that the first touch event is erroneous. The first touch event may occur proximate a first capture area for the user interface and the method may further include causing the first capture area for the user interface to be adjusted in response to the first touch event.

Claims

1. A method comprising:

receiving an indication of a first touch event, wherein the first touch event is received at a first capture area;

determining, via a touch mediation function, a first priority associated with the first capture area;

determining an input corresponding to the first touch event received at the first capture area;

providing the input to a user interface without delay in response to the first priority being a relatively high priority;

introducing a delay between determining the input and providing the input to the user interface in response to the first priority being a relatively low priority;

receiving an indication of a second touch event, wherein the second touch event is received at a second capture area during the delay between determining the input and providing the input to the user interface;

determining, via the touch mediation function, a second priority associated with the second capture area;

determining an input corresponding to the second touch event received at the second capture area; and

substituting the input corresponding to the second touch event for the input corresponding to the first touch event in response to the second priority being higher than the first priority.

2. The method of claim 1, wherein introducing a delay between determining the input and relaying the input comprises modifying the input according to the touch mediation function before providing to the user interface.

3. The method of claim 1, further comprising:

modifying the touch mediation function in response to the first priority being a relatively low priority.

4. The method of claim 3, wherein the touch mediation function comprises a touch event filtering map layer, wherein different capture areas of the touch event filtering map layer comprise different priorities.

5. The method of claim 4, wherein modifying the touch mediation function comprises modifying the priorities of at least one capture area.

6. The method of claim 1, further comprising:

receiving an indication of motion from a sensor; and

modifying the touch mediation function in response to receiving the indication of motion from the sensor.

7. The method of claim 1, wherein the apparatus is further caused to:

receive an indication of motion from a sensor; and

modify the touch mediation function in response to receiving the indication of motion from the sensor.

8. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to:

receive an indication of a first touch event, wherein the first touch event is received at a first capture area;

determine, via a touch mediation function, a first priority associated with the first capture area;

determine an input corresponding to the first touch event received at the first capture area;

provide the input to a user interface without delay in response to the first priority being a relatively high priority;

introduce a delay between determining the input and providing the input to the user interface in response to the first priority being a relatively low priority;

receive an indication of a second touch event, wherein the second touch event is received at a second capture area during the delay between determining the input and providing the input to the user interface;

determine, via the touch mediation function, a second priority associated with the second capture area;

determine an input corresponding to the second touch event received at the second capture area; and

substitute the input corresponding to the second touch event for the input corresponding to the first touch event in response to the second priority being higher than the first priority.

9. The apparatus of claim 8, wherein causing the apparatus to introduce a delay between determining the input and relaying the input comprises causing the apparatus to modify the input according to the touch mediation function before providing to the user interface.

10. The apparatus of claim 8, wherein the apparatus is further caused to:

modify the touch mediation function in response to the first priority being a relatively low priority.

11. The apparatus of claim 10, wherein the touch mediation function comprises a touch event filtering map layer, wherein different capture areas of the touch event filtering map layer comprise different priorities.

12. The apparatus of claim 11, wherein causing the apparatus to modify the touch mediation function comprises causing the apparatus to modify the priorities of at least one capture area.

13. A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising:

program code instructions for receiving an indication of a first touch event, wherein the first touch event is received at a first capture area;

program code instructions for determining, via a touch mediation function, a first priority associated with the first capture area;

program code instructions for determining an input corresponding to the first touch event received at the first capture area;

program code instructions for providing the input to a user interface without delay in response to the first priority being a relatively high priority;

program code instructions for introducing a delay between determining the input and providing the input to the user interface in response to the first priority being a relatively low priority;

program code instructions for receiving an indication of a second touch event, wherein the second touch event is received at a second capture area during the delay between determining the input and providing the input to the user interface;

program code instructions for determining, via the touch mediation function, a second priority associated with the second capture area;

program code instructions for determining an input corresponding to the second touch event received at the second capture area; and

program code instructions for substituting the input corresponding to the second touch event for the input corresponding to the first touch event in response to the second priority being higher than the first priority.

14. The computer program product of claim 13, wherein the program code instructions for introducing a delay between determining the input and relaying the input comprises program code instructions for modifying the input according to the touch mediation function before providing to the user interface.

15. The computer program product of claim 13, further comprising:

program code instructions for modifying the touch mediation function in response to the first priority being a relatively low priority.

16. The method of claim 15, wherein the touch mediation function comprises a touch event filtering map layer, wherein different capture areas of the touch event filtering map layer comprise different priorities.

17. The computer program product of claim 13, further comprising:

program code instructions for receiving an indication of motion from a sensor; and

program code instructions for modifying the touch mediation function in response to receiving the indication of motion from the sensor.
