Abstract

According to an aspect, a display device includes a display unit, a detecting unit, and a control unit. The display unit stereoscopically displays a display object. The detecting unit detects a first object and a second object in a three-dimensional space where the display object is displayed. The control unit changes the display object when a case is detected in which the display object is located between the first object and the second object in the three-dimensional space.

maintain the display object, that has been set to the tentatively selected state, at the initial position,

when the first object and the second object move from the first arrangement to a second arrangement in which a relative location of the first and second objects to said display object is different from the first arrangement, and then

move the display object from the initial position to a position between the first object and the second object where the display object is again in contact with said at least one of the first object and the second object that was in contact with the display object in the first arrangement,

when a distance between the first object and the second object is not widened for a longer period of time than a predetermined time in the second arrangement.

13. The display device according to claim 12, wherein

the first arrangement in which said at least one of the first object and the second object is in contact with the display object in the three-dimensional space includes a case in which a line connecting between the first object and the second object intersects a display surface of the display unit.

14. The display device according to claim 12, wherein

the detecting unit is configured to detect a first state in which at least one of the first object and the second object is in contact with the display object for a longer period of time than a predetermined time, and
