Touch Sensor Hand-Configuration Analysis

摘要

In certain embodiments, an apparatus includes controller circuitry and a touch sensor that includes first electrodes. The controller circuitry is configured to measure first capacitance values during a first time period, each first capacitance value associated with a respective first electrode. The controller circuitry is also configured to determine a first hand-usage value based at least on a distribution of the first capacitance values. The controller circuitry is also configured to estimate a hand-usage state based at least on the first hand-usage value. The hand-usage state indicates one of the following hand configurations: right-handed interaction with the touch sensor, left-handed interaction with the touch sensor, or two-handed interaction with the touch sensor.
