Abstract: A touchpad including a proximity detector configured to generate a proximity event by detecting whether an object is close to a touch surface, a coordinate recognizer configured to select one from among a relative coordinate mapping mode and an absolute coordinate mapping mode based on the proximity event and to predict coordinates of a touch point to be touched by the object, using the selected coordinate mapping mode, and a controller configured to control output of information about the predicted coordinates, is disclosed. If an object is close to a touch surface of a touchpad, it is predicted that a user desires to select a target. In this case, interaction with the user may be reduced by predicting and displaying a location to be touched by the object based on proximity of the object.
