Suppression of unintended touch objects
View Patent ↗An apparatus includes a touch sensor operable to sense objects that touch the touch sensor. The apparatus also includes a touch sensor controller operable to detect a first object and determine that the first object is an object that a user intends to touch the touch sensor. The touch sensor controller also defines an intended touch area associated with the first object and suppresses detection of touches that are outside of the defined intended touch area.
1. An apparatus comprising:
a touch sensor operable to sense a plurality of objects that touch the touch sensor, said touch sensor comprising a plurality of electrodes to be disposed on at least one substrate;
a touch sensor controller operable to:
detect a first object touching the touch sensor;
determine that the first object is an object that a user intends to touch the touch sensor;
define an intended touch area associated with the first object, the intended touch area comprising an area covering a portion of the plurality of electrodes; and
suppress detection of touches of the touch sensor that are outside of the defined intended touch area.
2. The apparatus of claim 1 , wherein the touch sensor controller is further operable to:
detect that the first object is moved from a first location to a second location within the intended touch area; and
adjust a location of the defined area based on the detected movement of the first object.
3. The apparatus of claim 1 , wherein the intended touch area is defined by a radius having a predetermined length extending from a location of the first object.
4. The apparatus of claim 3 , wherein the predetermined length is an adjustable user setting.
5. The apparatus of claim 1 , wherein the touch sensor controller determines that the first object is an object that a user intends to touch the touch sensor by determining that the first touch object is a stylus.
6. The apparatus of claim 1 , wherein the touch sensor controller is further operable to initiate suppression of unintended touches based at least in part upon determining that the first object is a stylus.
7. The apparatus of claim 1 , wherein the touch sensor controller determines that the first object is an object that a user intends to touch the touch sensor based at least upon one or more of a touch size, a touch pattern, and a signal strength.
8. An apparatus comprising:
a touch sensor operable to sense a plurality of objects that touch the touch sensor:
a touch sensor controller operable to:
detect a first object touching the touch sensor;
determine that the first object is an object that a user intends to touch the touch sensor;
define an intended touch area associated with the first object; and
suppress detection of touches that are outside of the defined intended touch area; and
wherein the touch sensor is further operable to:
determine that a predetermined time period since a detection of an object within the defined intended touch area is lapsed; and
discontinue suppressing detection of touches that are outside of the defined intended touch area.
9. A method comprising:
detecting a first object touching a touch sensor, said touch sensor comprising a plurality of electrodes to be disposed on at least one substrate;
determining that the first object is an object that a user intends to touch the touch sensor;
defining an intended touch area associated with the first object, the intended touch area comprising an area covering a portion of the plurality of electrodes; and
suppressing detection of touches of the touch sensor that are outside of the defined intended touch area.
10. The method of claim 9 , further comprising:
detecting that the first object is moved from a first location to a second location within the intended touch area; and
adjusting a location of the defined area based on the detected movement of the first object.
11. The method of claim 9 , wherein the intended touch area is defined by a radius having a predetermined length extending from a location of the first object.
12. The method of claim 11 , wherein the predetermined length is an adjustable user setting.
13. The method of claim 9 , further comprising determining that the first object is an object that a user intends to touch the touch sensor by determining that the first object is a stylus.
14. The method of claim 9 , further comprising initiating suppression of unintended touches based at least in part upon determining that the first object is a stylus.
15. A method comprising:
detecting a first object touching a touch sensor;
determining that the first object is an object that a user intends to touch the touch sensor;
defining an intended touch area associated with the first object; and
suppressing detection of touches that are outside of the defined intended touch area;
determining that a predetermined time period since a detection of a touch within the defined intended touch area is lapsed; and
discontinuing suppressing detection of touches that are outside of the defined intended touch area.
16. A system, comprising:
a computing device;
a display screen; and
a touch sensor, the touch sensor comprising:
a plurality of electrodes to be disposed on at least one substrate; and
a touch sensor controller operable to:
detect a first object touching the touch sensor;
determine that the first touch object is an object that a user intends to touch the touch sensor;
define an intended touch area associated with the first object, the intended touch area comprising an area covering a portion of the plurality of electrodes; and
suppress detection of touches of the touch sensor that are outside of the defined intended touch area.
17. The system of claim 16 , wherein the touch sensor controller is further operable to:
detect that the first object is moved from a first location to a second location within the intended touch area; and
adjust a location of the defined area based on the detected movement of the first object.
18. The system of claim 16 , wherein the intended touch area is defined by a radius having a predetermined length extending from a location of the first object.
19. The system of claim 16 , wherein the touch sensor controller determines that the first object is an object that a user intends to touch the touch sensor by determining that the first touch object is a stylus.
20. An apparatus comprising:
a touch sensor operable to sense a plurality of objects that touch the touch sensor;
a touch sensor controller operable to:
detect a first object touching the touch sensor;
determine that the first object is an object that a user intends to touch the touch sensor;
define an intended touch area associated with the first object; and
suppress detection of touches that are outside of the defined intended touch area; and
wherein the touch sensor controller is further operable to:
determine that a predetermined time period since a detection of a touch within the defined intended touch area is lapsed; and
discontinue suppressing detection of touches that are outside of the defined intended touch area.
