Patent number: 9811218Abstract: A processing system for a capacitive sensing device includes a sensor module and a determination module. The sensor module is for performing capacitive sensing in a sensing region using sensor electrodes. The sensing region includes a first sub-region and a second sub-region. The determination module is for detecting a first input object in the sensing region upon an initial contact of the first input object in the sensing region, determining positional information of the first input object, and determining, from the positional information, that the first input object is located in the second sub-region of the sensing region. Responsive to the first input object being located in the second sub-region of the sensing region, the determination module suppresses reporting of the first input object.Type: GrantFiled: December 18, 2014Date of Patent: November 7, 2017Assignee: Synaptics IncorporatedInventor: Tom Vandermeijden
