ABSTRACT:
The present invention is an interactive video training system with bar code access for use in combination with a videodisc on which training material is stored and a workbook having a printed index of the training material. A unique bar code is associated with each unique item in the printed index. The training system includes a bar code reading device for reading each unique bar code and a videodisc player for playing the training material which is stored on the videodisc. The videodisc player has a first microprocessor for receiving mode inputs and address inputs and a driving mechanism for rotatively driving the videodisc. The training system also includes a second microprocessor which is electrically coupled to the bar code reading device. The second microprocessor receives an input signal from the bar code reading device and processes the input signal in order to generate a set of output signals, which are the mode inputs and the address inputs. The first microprocessor, which is electrically coupled to the second microprocessor, controls the driving mechanism as the driving mechanism rotatively drives the videodisc to positions where the particular set of items are stored on the videodisc in order to access the unique set of items stored within the videodisc which corresponds to a particular associated bar code and retrieve the particular set of items in a particular sequence or pace.
