Abstract:
1. An input device, including: a contact sensing surface is configured to accept at least one object contact, wherein the contact sensing surface has at least one key region; a controller electrically connected to the contact sensing surface, wherein the controller comprises: a position-detecting unit configured to detect a position on the contact sensing surface contacted by the object; a memory unit configured to store at least one functional data corresponding to a key function; a key-triggering unit configured to read the functional data stored in the memory unit and activate the corresponding key function when the object contacts the key region of the contact sensing surface without a sliding within the key region; and a key function setting unit configured to change the functional data based on a direction and a distance of the object sliding within the key region and activate another key function corresponding to the changed functional data when the object is sliding within the key region a distance larger than a threshold distance, wherein the key function setting unit changes the functional data in the memory unit as representing a key function of scrolling or paging vertically or horizontally when the direction of object sliding is respectively substantially vertical or substantially horizontal and the distance of the object sliding is larger than the threshold distance.
