US 10,379,672 B2 · Dynamic proximity object detection

Abstract

A method of dynamically adjusting a sensitivity of sensor electrodes configured for capacitive sensing in a sensing region of an input device. The input device detects a first input in the sensing region, and acquires force information about the first input via one or more force sensors coupled to the sensing region. The input device dynamically adjusts a sensitivity of the sensor electrodes based at least in part on an amplitude and duration of the force. In some aspects, the input device may increase the sensitivity of the sensor electrodes when a force of the first input exceeds a force threshold for at least a first threshold duration. In some other aspects, the input device may restore the sensitivity of the sensor electrodes to a prior configuration when no input is detected in the sensing region for at least a second threshold duration.
