| Human reaction speed measuring instrument is a tool intended to calculate the speed of a person. The speed of human reactions itself is the time it takes a person to perform an action shortly after the person receives the information. Not so many measuring devices that can measure the speed of human reactions in detail. Detailed things that are human aids can be measured from the psychomotor side (action). Therefore, the purpose of this study is for a device that can calculate the speed of human reactions from the cognitive and motor side. In this research used SCAMPER method to explore idea, morphology chart for some components, and Pugh selection method to determine the selected design. After that also done the analysis. Changes in speed, speed of light, and light intensity. Measuring tool of human reaction speed which can measure time of cognitive velocity and psychomotor speed time. However, the measurement of the speed of human reactions still have many shortcomings so that researchers still have to with a better tool again. |
