1. An apparatus comprising:
- circuitry configured to;
determine, as a first determination result based on an output of a sensor, that an instruction object is within a predetermined distance of a surface of a display;
determine a position on the display corresponding to the first determination result;
acquire an image of an area surrounding the apparatus;
detect a presence of a facial feature in the captured image;
calculate a line-of-sight angle based on the detected facial feature; and
control the display to enlarge an area of a displayed interface and display the enlarged area offset from the position corresponding to the first determination result based on a distance between a reference vector projecting perpendicularly from the display at the position corresponding to the first determination result and a line-of-sight vector corresponding to the line-of-sight angle.

Abstract
An apparatus may include circuitry configured to determine, as a first determination result based on an output of a sensor, that an instruction object is within a predetermined distance of a surface of a display. The circuitry may acquire an image of an area surrounding the apparatus. The circuitry may detect a presence of a facial feature in the captured image. The circuitry may calculate a line-of-sight angle based on the detected facial feature. The circuitry may control the display to enlarge an area of a displayed interface based on the first determination result and the line-of-sight calculation.
