Abstract
A method for face detection management includes determining, for a first time, a presence of an input object in a sensing region of a capacitance input device. The presence is determined for the first time using a first baseline, and the input object satisfies a size threshold. The method further includes suppressing a reporting of capacitance input device during a predefined time period based on the presence of the input object, determining a disabled state of a display of a host, wherein the disabled state is in response to determining the presence of the input object for the first time, and determining, in response to an elapse of the predefined time period and for a second time, an absence of the input object in the sensing region. The absence of the input object is determined for the second time using a second baseline to account for the disabled state of the display. The method further includes performing an action based on determining the absence of the input object.
