Assignee: SYNAPTICS INCORPORATED
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 10:
11. An input device, comprising:
one or more piezoelectric devices configured to measure piezoelectric signals associated with an input object interacting with a sensing region, wherein the piezoelectric signals comprise a first set of piezoelectric signals and a second set of piezoelectric signals;
a plurality of capacitive sensors configured to measure corrective signals associated with the input object interacting with the sensing region; and
a processing system configured to:
obtain the piezoelectric signals;
obtain the corrective signals;
determine, based on the piezoelectric signals and the corrective signals, a plurality of events to be performed in response to the input object interacting with the sensing region, wherein determining the plurality of events comprises:
determining, based on the first set of piezoelectric signals, a first haptic event that is associated with the input object pressing down on the sensing region, and
determining, based on the second set of piezoelectric signals and the corrective signals, a subsequent haptic event that is associated with the input object releasing from the sensing region; and

provide haptic feedback based on the first haptic event and the subsequent haptic event.
