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.

Claims

1. An interactive training system with bar code access comprising a printed schematic representation having a printed index which has a set of associated bar codes each of which corresponds to a portion of the schematic and a unique set of items in the printed index related to said portion and further comprising:

a. bar code reading means for reading each of the set of associated bar codes of the printed index;

b. a videodisc player which stores information on a videodisc and which has a driving mechanism, which rotatively drives said videodisc, and a first microprocessor, which receives mode inputs and address inputs; and

c. a second microprocessor which is electrically coupled to said bar code reading means from which said second microprocessor receives an input signal whereby said second microprocessor processes said input signal and generates a set of output signals, which are said mode inputs and said address inputs, wherein said second microprocessor is electrically coupled to said first microprocessor of said videodisc player so that said first microprocessor controls said driving mechanism as said driving mechanism rotatively drives said videodisc to positions where the particular set of items are stored on said videodisc in order to access the unique set of items stored within said videodisc which corresponds to a particular associated bar code and retrieve the particular set of items in a particular sequence or pace, said second microprocessor being also electrically coupled to said bar code reading means.

3. An interactive training system with bar code access according to claim 1 wherein the schematic representation is a picture of parts of a machine or a list of the parts of the machine each of which is designated by name and each of which has a unique bar code associated with the name of each part of the machine whereby an operator may use said bar code reading means to retrieve information regarding a particular part of the machine.

4. An interactive training system with bar code access according to claim 1 wherein the schematic representation is a workbook by which a trainee is able to acquire specialized knowledge and learn skills by reading the lessons and answering the questions in the workbook on a subject and by viewing a video presentation of material which is interactively related to each area of the subject of the workbook wherein a unique bar code is associated with each area of the subject whereby an operator may use said bar code reading means to retrieve pictures and other information regarding a particular area of the subject.

2. An interactive instruction system with bar code access comprising a textbook or workbook having a schematic and a printed index which has a set of associated bar codes each of which corresponds to a portion of the schematic and a unique set of items in the printed index related to said portion and further comprising:

a. bar code reading means for reading each of the set of associated bar codes of the printed index;

b. a videodisc player which stores information on a videodisc and which has a driving mechanism, which rotatively drives said videodisc, and a first microprocessor, which receives mode inputs and address inputs; and

c. a second microprocessor which is electrically coupled to said bar code reading means from which said second microprocessor receives an input signal whereby said second microprocessor processes said input signal and generates a set of output signals, which are said mode inputs and said address inputs, wherein said second microprocessor is electrically coupled to said first microprocessor of said videodisc player so that said first microprocessor controls said driving mechanism as said driving mechanism rotatively drives said videodisc to positions where the particular set of items are stored on said videodisc in order to access the unique set of items stored within said videodisc which corresponds to a particular associated bar code and retrieve the particular set of items in a particular sequence or pace, said second microprocessor being also electrically coupled to said bar code reading means.
