An apparatus and method provide logic for processing information. In one implementation, an apparatus includes a display unit configured to display a first portion of content to a user. The display unit includes a display surface. A detection unit is configured to detect a distance between an interface surface and a reference point disposed along an operational tool of the user. A control unit configured to determine whether the distance falls within a threshold range, and generate a signal to display a second portion of content to the user, when the detected distance falls within the threshold range. The display unit is further configured to display the second content portion, based on the generated signal.
