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 reaction 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 a = .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.
