The objective of the present set of experiments was to characterize the dynamics of two types of actuator used in vibrotactile displays: a linear resonant actuator and a C2 tactor. Of particular interest was to determine how much the inputs delivered by these actuators changed under varying load conditions and when they were mounted at different locations on the body. When on a rigid surface the force...
The objective of the present set of experiments was to characterize the properties of travelling waves induced by vibrotactile stimulation of the skin and to determine whether these varied significantly at three different locations on the body: the palm of the hand, the forearm and the thigh. These locations are often considered for use in tactile displays used for spatial cuing. A custom designed...
The locus of vibrotactile stimulation is often used as an encoding cue in tactile displays developed for spatial orientation and navigation. However, the ability to localize the site of stimulation varies as a function of the number and configuration of the vibrating motors (tactors) in the display. As the inter-tactor distance decreases it has been found that the ability to localize a point of stimulation...
