Description

The invention relates to computing, in particular to devices for learning how to use the keyboard of a computer programmer operator.

The purpose of the invention is the expansion of didactic capabilities of the simulator.

The drawing shows a structural diagram of the simulator.

The simulator contains an operator panel (not shown) with sensors T-10 keys, ele- ment 10 OR 11, element 12, a pulse shaper (not shown), including a key 13 and a switch 14, a band-pass filter 15, a signal module selection unit 16 , threshold element 17, key 18, integrator 19, 15 first and second counters 20 and 21, first 22 and second 23 dividers, inputs 24 start and stop, third counter 25, third 26 and fourth 27 dividers and registration unit 28. 20

The simulator works as follows.

Signals xi (t) (i = 1.2 ..... 10), which display the operation of the keyboard of the fingers of the right and left hands of the operator-programmer, come from the sensors 25 by pressing the elements OR 11 and AND 12. These signals display the dynamics and the force of pressing ix of the fingers on the corresponding keys or their image of the keyboard of a personal computer or display. As pressure sensors, for example, strain gages can be used. ki, seismic sensors, displacement sensors and. etc.

The keys are pressed either only at least rarely (in this case, the signals are sent to the bandpass filter 15 through the key 13 and the switch 14), or, in the general case, several keys are pressed simultaneously. In this case, the signals from the output of the OR element 11 40 through the switch 14 are fed to the band-pass filter 15. Thus, using the switch 14, the configuration of the device circuit is changed to process the signals or the training program 45 by pressing keys one by one, or pressing them simultaneously.

On the bandpass filter 15, the signals Xi (t) are filtered out from the high frequency components. fifty

To implement further processing of signals of the same sign in the device circuit, a block 16 for isolating the module of this variable is used! XD) 1 = xz

In the process of working with the one- 55 keyboard, the programmer must make a certain effort to press the keys. If this force is less than necessary, then the output of the threshold element 17, the signal is zero. The signals that occur at the output of the horn element, control the operation of the key 18.

If the value of χι is greater than the threshold, then this signal from the output of the module allocation unit 16 through the key 18 is fed to the integrator 19, where the indicator and

Pi = / Xi dt, o

where ti is the time of existence of the signal at the output of the threshold element 17.

The counter 20 calculates the total time of interaction of the operator-programmer with the keyboard with an effort greater than the threshold value:

k t = Σ p, where k is the number of clicks with an effort greater than the threshold value.

The Pi indicator characterizes the current value of energy spent by the operator-programmer on pressing a key.

Counter 25 calculates experiment time ΐ ₃ . Its countdown starts from the moment the device is started until the experimenter stops it. The signals at the input 24 are reset to the initial state of the integrator 19, counters 20 and 25 of the time and the counter of the number of clicks. The number of presses η is fixed by the counter 21.

On the dividers 22, 23, 26 and 27, the following indicators are calculated, respectively:

t £ ta

The data processed by blocks 19. 21,

22, 23, 25, 26, and 27 are registered by the block

28, which can be used devices that enter information on paper, magnetic media, cathode ray tubes, displays, or specialized computers.

The invention makes it possible to increase the efficiency of the use of computer facilities both during the initial training of operator programmers, and through periodic training of specialists performing the work of the operator.
