Touch screen proximity sensing with accelerometer/gyroscope and finger grip suppression to prevent false ear touch

An electronic system, comprising:

• a touch panel;
• one or more processors;
• and
• memory storing one or more programs for execution by the one or more processors, the one or more programs comprising instructions for:
• measuring capacitance on a plurality of capacitance sensing electrodes of the touch panel;
• detecting a non-capacitance input indicating movement of the touch panel;
• determining whether the detected non-capacitance input indicates movement towards a user's face;
• in accordance with a determination that the detected non-capacitance input indicates movement towards the user's face, using a touch controller coupled to the touch panel to suppress touch signals that are extracted from the touch panel except for a designated portion of the plurality of capacitance sensing electrodes while maintaining proximity detection on the entire touch panel, wherein proximity detection detects proximity of the user's face to the touch panel;
• and
• while suppressing touch signals that are extracted from the touch panel except for the designated portion:
• detecting a touch input that originates from a first location on the touch panel within the designated portion and extends to a second location on the touch panel;
• and
• in response to determining that a distance from the first location to the second location is greater than a predefined minimum distance, enabling touch detection on the entire touch panel while maintaining proximity detection.

A non-transitory computer readable storage medium storing one or more programs configured for execution by one or more processors of an electronic system, the one or more programs comprising instructions for:

• at an electronic system including a touch panel:
• measuring capacitance on a plurality of capacitance sensing electrodes of the touch panel;
• detecting a non-capacitance input indicating movement of the touch panel;
• determining whether the detected non-capacitance input indicates movement towards a user's face;
• in accordance with a determination that the detected non-capacitance input indicates movement towards the user's face, using a touch controller coupled to the touch panel to suppress touch signals that are extracted from the touch panel except for a designated portion of the plurality of capacitance sensing electrodes while maintaining proximity detection on the entire touch panel, wherein proximity detection detects proximity of the user's face to the touch panel;
• and
• while suppressing touch signals that are extracted from the touch panel except for the designated portion:
• detecting a touch input that originates from a first location on the touch panel within the designated portion and extends to a second location on the touch panel;
• and
• in response to determining that a distance from the first location to the second location is greater than a predefined minimum distance, enabling touch detection on the entire touch panel while maintaining proximity detection.
