Abstract: A method may include performing a first low-power scan to detect an input object in a sensing region of an input device. The method may further include determining, using the first low-power scan, whether the input object is an object of interest. The method may further include performing a high-power scan of the sensing region when the input object is an object of interest. The method may further include performing a second low-power scan of the sensing region when the input object is an object of no interest.

Abstract: Capacitive sensing includes concurrently driving a first transmitter electrode with a first transmitter signal and a second transmitter electrode with a second transmitter signal. The first transmitter signal is based on a first digital code and the second transmitter signal is based on a second digital code. The first digital code and the second digital code each include at least one non-integer multiple. Capacitive sensing further includes receiving resulting signals using multiple receiver electrodes, the resulting signals include effects of the first transmitter signal and the second transmitter signal. Capacitive sensing further includes determining positional information based on the resulting signals.

Abstract: A system and method for input sensing comprises a display device having at least one piezoresistive sensing transistor. During a first period, a first resulting signal is received with a first data line by driving a first piezoresistive sensing transistor of a first subpixel of the display device with a first select signal. The first resulting signal corresponds to a change in resistance of the first piezoresistive sensing transistor. Further, at least one of force information and positional information associated with an input object may be determined at least partially based on the change in resistance.

Abstract: An input device described herein includes at least one hybrid electrode that is used to perform both capacitive sensing to detect an input object (e.g., a finger or stylus) and force sensing to determine the force applied by the input object on the input device. During a first time period, the input device drives a modulated signal on one more capacitive sensor electrodes to perform capacitive sensing. However, during a second time period, the input device drives a DC voltage across one or more of the capacitive sensor electrodes to perform force sensing. In one example, during the first time period, the input device drives the modulated signal on transmitter electrodes and measures resulting signals on receiver electrodes. During the second time period, however, the input device may drive the DC voltage across the transmitter or receiver electrodes to measure a force applied by the input object.

Abstract: A method and apparatus for determining an eye gaze direction of a user through one or more non-contact capacitive sensors. For at least some embodiments, a differential capacitance associated with a users' eye may be determined through at least one of the non-contact capacitive sensors. The differential capacitance may be based on capacitance measurements associated with the users' eye performed at different times. The eye gaze direction may be based, at least in part, on the determined differential capacitance. For some embodiments, two or more non-contact capacitive sensors may be positioned along an axis. Differential capacitance measurements from the two or more non-contact capacitive sensors may determine the eye gaze direction with respect to the axis.
