Abstract

A three-dimensional unlocking device (100) includes: a virtual-data generating unit (101) that generates three-dimensional lock data representing plural virtual objects arbitrarily arranged in a three-dimensional coordinate space; a display processing unit (102) that causes a display unit to display the plural virtual objects; a position acquiring unit (103) that acquires a three-dimensional position of a specific region of an operator in the three-dimensional coordinate space; an operation detecting unit (104) that detects a selecting operation performed by the operator with the specific region to the virtual objects; a selection-information acquiring unit (105) that acquires selection information indicative of identification information corresponding to a selected virtual object and a selected order, on the basis of the detected selecting operation; and a lock controlling unit (106) that unlocks a lock by comparing the acquired selection information with selection information that has been already registered.
