Abstract:

When tactors of a tactile display are mounted in a tactor carrier, e.g. a vest or a chair, vibrations will spread out through the skin and the carrier. Vibrations should be local to ensure good detection spreading through the skin or the environment has to be minimized. A literature study has been done to obtain the following design criteria Tactors should oscillate parallel to the skin at a frequency of 200 Hz. Tactors should be glued to the skin or coated with a material that does not slip easily. When the tactors cannot be attached free of slip, use tactors that oscillate perpendicular to the skin. The size of the contact area between the tactor and the skin should be small. Soft material encased in stiff material should be used between the tactor carrier and the tactor in order to reduce the amount of vibration energy emitted to the tactor carrier and to reflect energy to the skin
