Abstract
A touchpad system including a touchpad and a touch controller. The touchpad includes a plurality of force sensors and a touch sensor. The touch controller is in electrical communication with the touchpad and is configured to obtain a touch signal from the touch sensor and determine a signal-to-noise ratio of the touch signal. The touch controller is further configured to determine whether to enter a high noise mode based on the signal-to-noise-ratio of the touch signal. Upon determining to enter the high noise mode, the touch controller is further configured to obtain a force signal from the plurality of force sensors, determine a weighting of the touch signal and force signal based on the signal-to-noise ratio of the touch sensor, aggregate the touch signal and force signal based on the weighting, and determine a contact position of a user touch on the touchpad using the aggregated touch and force signals.
