Managing multiple touch sources with palm rejection
View Patent ↗For managing multiple touch sources with palm rejection, a method is disclosed that includes detecting an instrument touch on a touch screen of a computing device, the instrument touch performed by a handheld instrument, disabling user touch for a portion of the touch screen, the disabled portion selected in accordance with a usage pattern, and accepting a user touch of the touch screen outside of the disabled portion.
1. An apparatus comprising:
a processor;
a touch screen operatively coupled to the processor;
an instrument touch module that detects, at the touch screen, a touch from a handheld instrument;
a learning module that learns a usage pattern from a user of the computing device; and
a user touch module that disables user touch for a portion of the touch screen in response to the instrument touch, the disabled portion based on the usage pattern, wherein the portion of the screen is further based on a location of the instrument touch and an orientation of the handheld instrument.
2. The apparatus of claim 1 , further comprising a pattern module that stores one or more usage patterns including the learned usage pattern, wherein the user touch module disables a portion of the touch screen based on a usage pattern selected from the stored one or more usage patterns based on user interaction.
3. The apparatus of claim 2 , wherein the pattern module further receives the one or more usage patterns from a remote usage pattern server.
4. The apparatus of claim 2 , wherein the pattern module further transmits the learned usage pattern to a remote usage pattern server.
5. The apparatus of claim 1 , wherein the learning module learns the usage pattern based on training with a user.
6. The apparatus of claim 5 , wherein the training comprises the user executing a training application.
7. The apparatus of claim 1 , wherein the learning module adjusts a usage pattern based on a technique selected from the group consisting of crowd sourcing and historical use of the apparatus.
8. The apparatus of claim 1 , wherein the user touch module accepts a touch from a user at a location outside the disabled portion of the touch screen.
9. A method comprising:
detecting, by use of a processor, an instrument touch on a touch screen of a computing device, the instrument touch performed by a handheld instrument;
learning a usage pattern from a user of the computing device;
disabling user touch for a portion of the touch screen, the disabled portion selected based on the learned usage pattern, wherein the portion of the screen is further based on a location of the instrument touch and an orientation of the handheld instrument; and
accepting a user touch of the touch screen outside of the disabled portion.
10. The method of claim 9 , further comprising transmitting the learned usage pattern to a remote usage pattern server.
11. The method of claim 9 , further comprising receiving one or more usage patterns from a remote usage pattern server.
12. The method of claim 9 , further comprising adjusting the usage pattern based on historical use of the computing device.
13. A program product comprising a non-statutory computer readable storage medium that stores code executable by a processor to perform:
detecting an instrument touch on a touch screen of a computing device, the instrument touch performed by a handheld instrument;
learning a usage pattern from a user of the computing device;
disabling user touch for a portion of the touch screen, the disabled portion selected-based on the learned usage pattern; and
accepting a user touch of the touch screen outside of the disabled portion.
14. The program product of claim 13 , the code further receiving the usage pattern from a remote usage pattern server.
15. The program product of claim 13 , the code further transmitting a learned usage pattern to a remote usage pattern server.
16. The program product of claim 13 , the code further adjusting the usage pattern based on historical use of the computing device.
17. The program product of claim 13 , wherein the disabled portion is further based on a characteristic of the instrument touch selected from the group consisting of a location of the instrument touch, and an orientation of the handheld instrument.
18. An apparatus comprising:
a processor;
a touch screen operatively coupled to the processor;
an instrument touch module that detects, at the touch screen, a touch from a handheld instrument;
a learning module that learns a usage pattern from a user of the computing device; and
a user touch module that disables a portion of the touch screen in response to the instrument touch, the disabled portion based on the learned usage pattern.
19. The apparatus of claim 18 , further comprising a pattern module that stores one or more usage patterns including the learned usage pattern, wherein the pattern module receives a usage pattern from a remote usage pattern server and wherein the user touch module disables a portion of the touch screen based on a usage pattern selected from the stored one or more usage patterns based on user interaction.
20. The apparatus of claim 18 , wherein the learning module adjusts a usage pattern based on a technique selected from the group consisting of crowd sourcing and historical use of the apparatus.
21. The apparatus of claim 18 , wherein the user touch module accepts a touch from a user at a location outside the disabled portion of the touch screen.
