given to 10. The learner's answer to the question can be written by writing the letters of the answer on the key map displayed on the monitor receivers 2a to 2d using the light pen 4.
This is done by selecting from a to 4d. The light pens 4a to 4d are provided with a light receiving element, which generates an output signal according to the trajectory of the light beam, and this output signal is given to the computer 10 to determine the contact position of the light pens 4a to 4d. The letter selected by the learner is then determined and compared with the correct answer to the pre-programmed question. The operations of the tape recorders 8a to 8d, the switch circuits 7 and 9, and the image storage device 5 are controlled by instructions from the computer 10.

Here, an example of the learning and education program will be explained with reference to FIG. 3.
Based on the reproduced output, an explanation image is displayed on the monitor receivers 2a to 2d of each booth 1a to 1d, and the explanation is transmitted to each learner through the headphones 3a to 3d. This explanation pertains to the knowledge needed to answer the next question. Next, a question image is displayed on the monitor receiver, and
The audio output (questions) from the tape recorder is transmitted through the headphone.

For example, questions regarding music include questions such as the length of musical notes. When the question is finished, the question image and the key map 11 based on the signal from the character generating circuit 6 are displayed on the screen of the monitor receiver. The key map 11 is a list of alphabets, numbers, etc., and the answer to a question is constructed by selecting a predetermined alpha, number, etc. from the key map 11. As an answer to this,
There can be various formats for selecting the correct answer number for multiple-choice questions, or for constructing spellings according to the English alphabet. and,
The method by which the learner answers the questions is by using the light pens 4a to 4d. In other words, the video image on the monitor receiver is electrically divided according to the XY coordinates, and when a light pen touches the video image, the contact position is detected, and from this detection it is possible to determine which alphabet, etc., has been selected. is electronic computer 10
, and the learner's answer can be determined. It is determined in the electronic computer 10 whether or not this answer is correct, and a determined image is displayed on the monitor receiver according to the result of the determination. There are two types of judgment images: one that indicates a correct answer, and one that indicates an incorrect answer. If the answer is correct, the process advances to the next learning step; if the answer is incorrect, the process returns to the step where the question is asked again. In this case, instead of simply returning to the question stage, it may be possible to branch to a step such as advice.

In this example, superimposed on the judgment image that is displayed when the learner's answer is wrong, for example, a message such as "Say Kaiha XX
The message 12 "x" is displayed. A video signal corresponding to the message display 12 can be generated by the character generation circuit 6. That is, the character generation circuit 6 is configured to generate pattern signals corresponding to characters such as numbers and alphabetic characters, and a correct message display 12 is displayed based on a command from the computer 10. in this case,
If no correct answer is given even after repeating the same question several times, the above-mentioned message of the correct answer is displayed and the process proceeds to the next step.

According to the present invention described above, it is not necessary to prepare a judgment image corresponding to each question, but a judgment image indicating a correct answer or a wrong answer (in addition to this, an advice image may also be used). ) can be made common to each question. Therefore, the capacity of the image storage device 5 can be small, and the access time can be shortened. Of course, since messages such as correct answers are superimposed and displayed, the learning effect is not impaired.

The image storage device 5 in the example of the present invention described above is composed of a video signal storage device in which one frame of image signals with 120 addresses is stored and a magnetic disc recording/reproducing device (VSR). The address signal for the video signal storage device is reproduced by the aforementioned tape recorders 8a to 8d, thereby selecting one predetermined frame of the video signal. In such a video signal storage device, a plurality of tracks in which address signals and video signals are recorded on a card-like magnetic sheet are formed in parallel, and the magnetic sheet is wound around a guide drum in a cylindrical shape.
