ELECTRONIC DEVICE WITH TOUCH-SENSITIVE DISPLAY AND GESTURE-DETECTION |
| 摘要 |
A method includes utilizing transmitters and receivers in an electronic device to detect at least one object spaced from a touch-sensitive display of the electronic device, determining first signal values utilizing touch sensors of the touch-sensitive display to obtain baseline noise values when no touch is detected and the transmitters are transmitting, and when a touch is detected, applying the baseline noise values to second signal values to reduce the effect of noise when identifying the touch location. |
