Abstract: Embodiments are directed to a user input device and methods for expanding an input area in response to an estimation of the accuracy of touch input or the likelihood that a series of touches will hit an intended touch target area. In one aspect, an embodiment includes a first capacitive area defined by a first electrode and a second capacitive area defined by the first electrode and a second electrode. The embodiment further includes a processing unit that may be configured to, in a first mode, execute an operation in response to a touch received in the first capacitive area. The processing unit may be configured to, in a second mode, execute the operation in response to the touch received in the second capacitive area.
