<p>A distance calculation section acquires first position information indicating the position of a part of the body of each user shown in an image taken by an imaging unit. A user information analysis section detects an operation area in which the user can perform operation by using the part of the body, on the basis of the first position information. When an operation area is detected, the user information analysis section identifies the user having the part of the body indicated by the first position information as an operator. The user information analysis section identifies, among operator candidates, a user having a part of the body in an operation area as an operator and also identifies the user other than the user identified as the operator among the operator candidates as a user who cannot perform operation. As a result, operability is improved.</p> |
