1/2 second’. It means that decreasing or decreasing & increasing amplitude of
vibrotactile stimulus for short duration (i.e., 1/4 or 1/2 second) and pausing it for
short duration (i.e., 3/4 or 1/2 second) give us relatively more pleasure than others.
By the way, the least pleasurable haptic icon is ‘continuing stimuli with fixed
amplitude for 1 second’, which means that continuous vibrotactile stimuli with fixed
amplitude without any pause give us the least pleasurable experience.
In conclusion, the experiments of this study show (1) we can make a variety of
candidates of haptic icons using the combination of rhythm patterns and macro
wave types; and (2) we can find effective haptic icons that are distinguishable from
each other ...
