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;

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 first 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.

2. The method according to claim 1, wherein the first touch event occurs proximate a first capture area for a user interface, and wherein the method further comprises causing the first capture area for the user interface to be adjusted in response to the first touch event.

3. The method according to claim 1, further comprising receiving an indication of a second touch event, wherein determining, by the touch mediation function, if the first touch event is an erroneous touch event comprises assigning a priority to each of the first touch event and the second touch event, and determining that the touch event with the lower priority is erroneous.

4. The method according to claim 3, wherein the indication of the second touch event is received within a predetermined amount of time of receiving the indication of the first touch event.

5. The method according to claim 4, wherein the first touch event is received at a first capture area corresponding to a first priority area and wherein the second touch event is received at a second capture area corresponding to a second priority area, and wherein the priority of the first touch event corresponds to a priority of the first priority area and wherein the priority of the second touch event corresponds to a priority of the second priority area.

6. The method according to claim 1, wherein the touch mediation function comprises a touch event map layer, and wherein the touch event map layer comprises at least two priority levels mapped to at least two areas of a touch screen interface.

7. The method according to claim 1, further comprising adjusting a touch event parameter of at least one user interface component in response to receiving the first touch event.

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:

provide for receiving an indication of a first touch event;

provide for determining, by a touch mediation function, if the first touch event is an erroneous touch event;

provide for 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

provide for 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.

9. The apparatus according to claim 8, wherein the first touch event occurs proximate a first capture area for a user interface, and wherein the apparatus is further caused to provide for adjusting the first capture area for the user interface to in response to the first touch event.

10. The apparatus according to claim 8, wherein the apparatus is further caused to receive an indication of a second touch event, wherein determining, by the touch mediation function, if the first touch event is an erroneous touch event comprises assigning a priority to each of the first touch event and the second touch event, and determining that the touch event with the lower priority is erroneous

11. The apparatus according to claim 10, wherein the indication of the second touch event is received within a predetermined amount of time of receiving the indication of the first touch event.

12. The apparatus according to claim 11, wherein the first touch event is received at a first capture area corresponding to a first priority area and wherein the second touch event is received at a second capture area corresponding to a second priority area, and wherein the priority of the first touch event corresponds to a priority of the first priority area and wherein the priority of the second touch event corresponds to a priority of the second priority area.

13. The apparatus according to claim 8, wherein the touch mediation function comprises a touch event map layer, and wherein the touch event map layer comprises at least two priority levels mapped to at least two areas of a touch screen interface.

14. The apparatus according to claim 8, wherein the apparatus is further caused to adjust a touch event parameter of at least one user interface component in response to receiving the first touch event.

15. A computer program product comprising at least one 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;

program code instructions for determining, by a touch mediation function, if the first touch event is an erroneous touch event;

program code instructions for 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

program code instructions for causing the first touch event to not be sent to the application in response to the touch mediation function determining that the touch event is not erroneous.

16. The computer program product according to claim 15, wherein the first touch event occurs proximate a first capture area for a user interface, and wherein the computer program product further includes program code instructions for causing the first capture area for the user interface to be adjusted in response to the first touch event.

17. The computer program product according to claim 15, further comprising program code instructions for receiving an indication of a second touch event, wherein the program code instructions for determining, by the touch mediation function, if the first touch event is an erroneous touch event comprises program code instructions for assigning a priority to each of the first touch event and the second touch event, and program code instructions for determining that the touch event with the lower priority is erroneous.

18. The computer program product according to claim 17, wherein the indication of the second touch event is received within a predetermined amount of time of receiving the indication of the first touch event.

19. The computer program product according to claim 18, wherein the first touch event is received at a first capture area corresponding to a first priority area and wherein the second touch event is received at a second capture area corresponding to a second priority area, and wherein a priority of the first touch event corresponds to the priority of the first priority area and wherein a priority of the second touch event corresponds to the priority of the second priority area.

20. The computer program product according to claim 15, wherein the touch mediation function comprises a touch event map layer, and wherein the touch event map layer comprises at least two priority levels mapped to at least two areas of a touch screen interface.
