Successful performance in sports depdepends on the ability of how quickly one reacts to the signal or environmental stimuli. From the viewpoint, reaction time(RT) and movement time(MT) are considered to be important not only in applied study emphasizing performance, but experimental settings. Though there has been several instruments in measuring RT, most of them are not generally utilized due to the high expenses as digital timer and the limitation in collecting data. Furthermore, there has been questions about the accuracy in measurement, because many researchers measured RT and MT without testing the accuracy of a program. The Multi-Purpose Reaction Timer was developed to measure RT and MT and to handled the collected data efficiently in various experimental situations by using the computer above the level of 16 bit AT. The Multi-Purpose Reaction Timer is expected to increase the accuracy of measurement and to facilitate the experimental control by comparing the measured time with digital timer.
