Touch system inadvertent input elimination
View Patent ↗In one aspect a method is provided that includes: detecting touch input at a first touch point on a touch screen; detecting touch input at a second touch point on the touch screen within a predetermined time of detecting said touch input at the first touch point, the second touch point being within a predefined proximity to the first touch point; and performing an action to eliminate touch input detected at the second touch point on the touch screen. Other aspects are described.
1. A method comprising:
detecting touch data input at a first touch point on a touch screen;
detecting sequential touch data input at a second touch point on the touch screen within a predetermined time of detecting said touch data input at the first touch point, the second touch point being within a predefined proximity to the first touch point; and
performing an action to eliminate the touch data input detected at the second touch point on the touch screen.
2. The method of claim 1 , wherein the action to eliminate the touch data input detected at the second touch point on the touch screen comprises filtering the touch data input detected at the second touch point on the touch screen such that the touch data input detected at the second touch point on the touch screen is not registered.
3. The method of claim 1 , wherein the action to eliminate the touch data input detected at the second touch point on the touch screen comprises:
detecting touch input which is a reverse of a sequence of input represented by the touch data input at the first touch point and the touch data input at the second touch point; and
undoing a result of the touch data input at the second touch point.
4. The method of claim 1 , wherein the action to eliminate the touch data input detected at the second touch point on the touch screen comprises:
in response to detecting the touch data input at the first touch point and detecting the touch data input at the second touch point on the touch screen within a predetermined time, activating a program module that:
detects touch input which is a reverse of a sequence of input represented by the touch data input at the first touch point and the touch data input at the second touch point; and
undoes a result of the touch data input at the second touch point.
5. The method of claim 1 , wherein the first touch point and the second touch point are associated with adjacent soft keys on the touch screen.
6. The method of claim 1 , wherein the predetermined time is less than 0.1 seconds.
7. The method of claim 1 , wherein the touch screen comprises a touch screen implemented on a smart phone.
8. The method of claim 1 , wherein the touch screen comprises a touch screen implemented on tablet computing device.
9. The method of claim 1 , wherein the predetermined time is less than 1 second.
10. A system, comprising:
one or more processors;
a memory in communication with the one or more processors; and
a touch screen;
the memory storing program instructions that when executed by the one or more processors:
detect touch data input at a first touch point on a touch screen;
detect sequential touch data input at a second touch point on the touch screen within a predetermined time of detecting said touch data input at the first touch point, the second touch point being within a predefined proximity to the first touch point; and
perform an action to eliminate the touch data input detected at the second touch point on the touch screen.
11. The system of claim 10 , wherein the action to eliminate the touch data input detected at the second touch point on the touch screen comprises filtering the touch data input detected at the second touch point on the touch screen such that the touch data input detected at the second touch point on the touch screen is not registered.
12. The system of claim 10 , wherein the action to eliminate the touch data input detected at the second touch point on the touch screen comprises:
detecting touch input which is a reverse of a sequence of input represented by the touch data input at the first touch point and the touch data input at the second touch point; and
undoing a result of the touch data input at the second touch point.
13. The system of claim 10 , wherein the action to eliminate the touch data input detected at the second touch point on the touch screen comprises:
in response to detecting the touch data input at the first touch point and detecting the touch data input at the second touch point on the touch screen within a predetermined time, activating a program module that:
detects touch input which is a reverse of a sequence of input represented by the touch data input at the first touch point and the touch data input at the second touch point; and
undoes a result of the touch data input at the second touch point.
14. The system of claim 10 , wherein the first touch point and the second touch point are associated with adjacent soft keys on the touch screen.
15. The system of claim 10 , wherein the predetermined time is less than 0.1 seconds.
16. The system of claim 10 , wherein the system is a smart phone.
17. The system of claim 10 , wherein the system is a tablet computing device.
18. The system of claim 10 , wherein the system is a kiosk device.
19. The system of claim 10 , wherein the predetermined time is less than 1 second.
20. A program product, comprising:
a storage medium having program code embodied therewith, the program code executable by the processor and comprising:
program code that detects touch data input at a first touch point on a touch screen;
program code that detects sequential touch data input at a second touch point on the touch screen within a predetermined time of detecting said touch data input at the first touch point, the second touch point being within a predefined proximity to the first touch point; and
program code that perform an action to eliminate touch data input detected at the second touch point on the touch screen.
