First Claim
1. A command issuing device comprising:
- an acquiring unit configured to acquire a moving image by capturing a hand of an operator;
a projection area recognizer configured to recognize a projection area of a projection finger in the moving image, the projection finger being one of fingers onto which one of pictures of a graphical user interface (GUI) is projected;
a projector configured to project one of the pictures of the GUI onto the projection area;
an operation area recognizer configured to recognize an operation area of an operation finger in the moving image, the operation finger being one of fingers which is assigned to operate the GUI;
a selection determining unit configured to measure an overlapping degree of the projection area and the operation area to determine whether or not the GUI is selected; and
a issuing unit configured to issue a command associated with the GUI when it is determined that the GUI is selected.
