Program using the LPT-por for determining the speed of human reaction to the visual signal.
The program can operate in two modes.
1) Program *.sr
The user himself writes sr-program (text files with the extension *.sr), which specifies the following parameters: the firing order of 12 LEDs connected to the outputs of LPT port (Scheme to Help); glow duration; pause between the LEDs glow in milliseconds.
On the basis of the random numbers are generated randomly the following values: LED number from 1 to 12; the pause between the different LEDs glow in milliseconds T2 (interval is defined in the settings from minimum to maximum). LED emission time T1 is the same for all the LEDs and is set in the settings. Automatically created Random.sr file can be used in the "Program *.sr" mode.
The LEDs are located in different areas of the field of vision of the test person. The subject must quickly press the button when you turn on the LEDs. The reaction rate in the table is written to the output file result.txt. Reaction speed is the time from the start signal until the response of the organism. After practice, the reaction rate increases.
