Abstract
A computer-implemented method is disclosed. The method includes: receiving a first signal from a first sensor of the device, the first signal indicative of a grounding condition of the device; setting one or more touch detection thresholds based on the grounding condition; receiving a touch signal from a touch sensor of the device, the touch signal indicative of a touch by an object; and determining whether one or more parameters of the touch signal exceeds the one or more touch detection thresholds.
Claims20
A device comprising:
- a touchscreen configured to provide a touch signal indicative of a first contact on the touchscreen;
- a sensor configured to provide a signal indicative of a second contact on a portion of the device different from the touchscreen;
- and
- a processor operably coupled to both the touchscreen and the sensor and configured to:
- detect the touch signal indicative of the first contact on the touchscreen;
- in accordance with a determination that there is the second contact on the portion of the device different from the touchscreen, determine whether one or more parameters of the touch signal exceed one or more first touch detection thresholds;
- and
- in accordance with a determination that there is no second contact on the portion of the device different from the touchscreen, determine whether the one or more parameters of the touch signal exceed one or more second touch detection thresholds, wherein the one or more second touch detection thresholds is different from the one or more first touch detection thresholds.
A method comprising:
- at a device comprising a touchscreen configured to provide a touch signal indicative of a first contact on the touchscreen, a sensor configured to provide a signal indicative of a second contact on a portion of the device different from the touchscreen, and a processor operably coupled to both the touchscreen and the sensor:
- detecting the touch signal indicative of the first contact on the touchscreen;
- in accordance with a determination that there is the second contact on the portion of the device different from the touchscreen, determining whether one or more parameters of the touch signal exceed one or more first touch detection thresholds;
- and
- in accordance with a determination that there is no second contact on the portion of the device different from the touchscreen, determining whether the one or more parameters of the touch signal exceed one or more second touch detection thresholds, wherein the one or more second touch detection thresholds is different from the one or more first touch detection thresholds.
A non-transitory computer readable storage medium storing instructions that, when executed by a device including a touchscreen configured to provide a touch signal indicative of a first contact on the touchscreen, a sensor configured to provide a signal indicative of a second contact on a portion of the device different from the touchscreen, and a processor operably coupled to both the touchscreen and the sensor, cause the processor to:
- detect the touch signal indicative of the first contact on the touchscreen;
- in accordance with a determination that there is the second contact on the portion of the device different from the touchscreen, determine whether one or more parameters of the touch signal exceed one or more first touch detection thresholds;
- and
- in accordance with a determination that there is no second contact on the portion of the device different from the touchscreen, determine whether the one or more parameters of the touch signal exceed one or more second touch detection thresholds, wherein the one or more second touch detection thresholds is different from the one or more first touch detection thresholds.
