Abstract:

An experiment was performed in which fifteen subjects responded to three separate warning devices an audio visual, and tactile device. Reaction times to each randomly presented device were measured while each subject was simultaneously engaged in piloting a personal flight simulator. Instructions to the subjects were continually presented visually on a TV monitor and verbally through a set of earphones. The mean reactions times for each device were compared using a difference of means t-test. The results showed that the tactile device produced significantly faster reaction times at the alpha .01 significance level. This led to the conclusion that a tactile warning device could be effective in a flight environment where visual and auditory senses can easily be overloaded.
