Abstract: An assembly work support system includes a training and simulation mode and a work-support mode, with an operator controlling voice or display output by interactive input. The assembly work support system accepts interactive input from the operator in the form of user-interactive control of his or her review of processes to be learned, and includes a simulation mode that gives feedback messages to the operator, a teaching portion with multimedia instructions and simulation exercises with feedback. A central processor or server gathers work flow data and evaluates the data.
