Claim One:
1. An apparatus for processing a user input, the apparatus comprising: a sensor configured to output event signals in response to sensing a movement of an object, wherein the event signals comprise information indicating pixels sensing an event corresponding to a part, which the movement is sensed, of the object, among sensing pixels of the sensor, wherein each of the pixels senses the event based on a change of input light due to the movement; and a processor configured to determine whether the event signals correspond to a first mode input for a tracking operation, by comparing a scattering of the plurality of pixels to a threshold value, and to track the movement in response to the determination that the event signals correspond to the first mode input, wherein the threshold value is greater than a first scattering of pixels corresponding to at least a part of a finger, and the threshold value is smaller than a second scattering of pixels corresponding to a hand.
