1. Apparatus comprising:
- a gesture recognizer adapted to monitor gestures in a field of view of a camera, and adapted to provide control information in accordance with the monitored gestures to a vision system;
a key recognizer adapted to monitor a key in a field of view of the camera and adapted to provide key information to the vision system;
a breakout box having at least two signaling elements, one of the at least two signaling elements being configured to communicate to a human user system mode information, and another of the at least two signaling elements being configured to communicate to a human user numerical value information; and
a setup control unit, cooperative with the gesture recognizer, the key recognizer, and the breakout box, the setup control unit being adapted to use the gesture control information and the key information to adjust a plurality of setup degrees of freedom of the camera, and adapted to provide the system mode information and the numerical value information to the breakout box.

Abstract
An apparatus and method are disclosed for setting up a vision system having a camera and a vision processor cooperative with the camera. The apparatus includes a gesture recognizer, a key recognizer, a breakout box having at least two signaling elements, and a setup control unit that is cooperative with the gesture recognizer, the key recognizer, and the breakout box. The combination of using a key and a gesture set as herein described is substantially superior, as compared with known user interfaces for setting up a vision system that has been previously been engineered, in terms of low-cost, convenience, ease-of-use, simplicity, and speed.
