(54) ADAPTIVE DEVICE FOR TEACHING WORK ON KEYBOARDS

The invention relates to automation and computing, and more specifically to teaching aids, and can be used when training in typewriters, punch keyboards, displays, telegraph devices, and the like. with two oppositely connected output diodes: the pulse generator is connected to the coincidence circuit, in which the trigger is in turn connected, and the outputs of the differentiating circuit diodes are connected to the coincidence circuit, and you are connected to one of the diodes directly and the other through the trigger. . A device is known comprising a program block, a pulse generator, a display board, a comparison circuit, a keyboard sensor, counters and OR circuits, as well as a decision block and a switching circuit 1.

However, this device has low didactic capabilities, as it is. It does not take into account the state of the learner and his level of learning, which is an important factor in intensive training in motor skills.

The closest technical solution to the invention is an adaptive device for training, skills

from work on key instruments, containing a keyboard sensor, a comparison unit, a tape-testing mechanism, a reading unit, a display board, a recording circuit, a switching unit, a memory register, a comparison circuit,

10 pulse counter and pulse generator 2.

A disadvantage of the known device is that it has low didactic possibilities, not

15 takes into account the state of the student and his level of training and does not allow testing other methods of training P1 on it, except for the classical training by trial and error, since

20, the feed rate of characters depends only on the number of mistakes made. . those. The regulation of the speed of presenting information is carried out on the basis of a probabilistic criterion determined by the ratio of the number of mistakes made to the total number of signs displayed, and depending on the number of mistakes made, the speed either increases or decreases. The aim of the invention is to increase the didactic capabilities of the device by adjusting the speed of issuing information, depending on the speed and accuracy of the character presentation. on the basis of an objective optimal criterion, which depends both on the number of mistakes made and on the speed of the input information. J This goal is achieved by having a device comprising a keyboard connected to a comparison unit, connected to an error counter and to a switching unit connected to an error fixing unit and. through the memory unit with the information input unit and with the register that is connected to the comparison unit, to the information presentation unit and through the driver to the pulse generator, the rhythm signal amplifier connected to the pulse generator and sequentially connected time specifying the block connected to the counter A pulse counter connected to the keypad and an optimal rate for the presentation of information connected to the error counter and the pulse generator. In the case of the determination of the optimal rate of presentation of information, the decoder of the rate of input of information, the decoder of the number of errors and the matrix of elements are used. And, the inputs of the decoders are the inputs of the block, and the outputs are bit-wise connected to the inputs of the matrix of elements And, the outputs of which are the outputs of the block. . The drawing shows a functional diagram of the device proposed. The device includes a keyboard 1, a comparison unit 2, a register 3, a memory block 4, an information input block 5, a pulse counter 6, an error counter 7, a switching block 8, a block 9 for determining the optimal speed information, pulse generator 10, amplifier AND rhythm signals, driver 12, information presentation unit 13, error fixing unit 14, and time master unit 15. The device operates as follows. Prior to the student’s work, for example, on a typewriter of the information input unit 5, training information is entered into the memory unit 4, for example, text containing several thousand character units, which then before starting work at power on; the device is transferred to register 3, and from there to block 13 the presentation of the formation. As soon as the student begins to work on the keyboard 1 (it is assumed that the study of the keyboard, the location of the hands and fingers before this is studied), the comparison of the entered information with the reference one is performed, the number of errors and the number of characters entered are determined at the same time. Two values: the number of errors made and the number of characters entered for a specified period of time are received in block 9 for determining the optimal rate of presentation of the formation, formation. In block 9, information on the number of entered characters for a given period of time goes to the decoder for the rate of input of information, and information on the number of errors - to the decoder for the number of errors. The outputs of both de; encoders are bitwise connected to the AND circuits with decoupling elements forming a matrix, the outputs of which are the outputs of the AND elements with the disconnection elements combined diagonally from right to left and from top to bottom. Moreover, the matrix is constructed in such a way that it implements the function of the table formed by the number of errors and the averaged data input rate. At the intersection of the rows and columns of this table (based on experimental data), the optimal rate of presentation of information to the student under certain requirements is recorded. The outputs of block 9 for determining the optimal rate of presentation of information, i.e. the matrix outputs are connected to a pulse generator 10, which is a tunable frequency generator, the number of inputs of which corresponds to the number of outputs of the block-9 determining the optimal presentation speed. The generator of 10 pulses is tuned in such a way that, depending on the signal from block 9, it generates pulses, the frequency KOTOJXJX corresponds to the optimal speed of presenting information to the student. From the output of the pulse generator 10, one of the signals comes into the amplifier 11 of the rhythm signals, which serves to set the work rhythm depending on the state of the student, and the other through the driver 12, into the register 3 so as to control the rate of presentation of information coming from the register 3. Switching unit 8 is connected to comparison unit 2 and performs two functions. Its first function is to issue a command to memory block 4 to rewrite the next piece of information from block 4 to register 3, as soon as the previous piece of information has been compared. Its second function is to block error fixing unit 14 from block 2 comparing signals with dibok, i.e. symbolic indication of the location of the error, which is an important control function.

Thus, individual learning of motor skills takes place; Kam based on the state of the student and his level of training at the moment of training.

The implementation of an adaptive device for training on keyboard devices according to this scheme and the introduction of new connections between blocks allows you to organize an effective process of training on keyboard devices by constantly taking into account the level of learning and the state of the learner.

All this will reduce the time for preparation and improve the quality of training for digital computer operators, telegraph operators and. etc.
