Claim One:
1. A user interface apparatus, comprising: a mobile display unit comprising an object display area, wherein: the mobile display unit displays a remote controller virtual object in the remote controller virtual object display area, the remote controller virtual object comprises a plurality of control keys associated with different user interface functions for controlling a separate stationary display unit by the user pressing the plurality of control keys on the mobile display unit; a detection area control unit that: defines a detection area for each control key of the remote controller virtual object, wherein the detection area includes a size and a location within the remote controller virtual object display area; and changes both the size and the location of the detection area of a respective control key of the plurality of control keys to create a modified detection area, wherein the modified detection area enlarges and redistributes the detection area of the respective control key of the plurality of control keys of the remote controller virtual object such that a user can control the stationary display unit by manipulating the plurality of control keys on the mobile display unit with minimized user input error while the user is concurrently viewing both the remote controller virtual object on the mobile display unit and associated content output on the stationary display unit; and an activation detection unit that detects a position of a user activation and a drag operation from the position of the user activation; wherein the detection area control unit changes the detection area of the respective control key after the activation detection unit detects the activation position as being within the detection area of the respective control key and detects that the drag operation ends outside of the detection area of the respective control key; and wherein both the size and location of the detection area of the respective control key are changed based on a location of the activation position within the detection area of the respective control key and a location at which the drag operation ends outside of the detection area of the respective control key.
