The input device includes a first portion comprising a touch sensor having a sensing area. The touch sensor includes a plurality of transmitter electrodes and a plurality of receiver electrodes. The input device also has a second portion comprising a plurality of features. A sensor circuit is configured to drive the plurality of transmitter electrodes with sensing signals and receive resulting signals from the plurality of receiver electrodes. A processing system is configured to generate an acquired image from at least a portion of the sensing area; compare the acquired image to a reference image, wherein the reference image includes data corresponding to the plurality of features; and determine whether the input device is in the closed state based on the comparison of the acquired image to the reference image.
