Abstract
A tactile transducer is able to provide a tactile display or serve as a tactile input sensor. Paired contactors having contactor tips separated by a gap are connected to transducer means (an actuator or sensor). Variations in the gap distance can create a tactile experience through skin stretch, or provide tactile input in sensor mode. The contactors are resiliently supported to bear against a sensing finger with relatively constant pressure.
