Abstract
An active drive is used to improve the response time of any vibrotactile transducer. A closed loop implementation of such a drive monitors the vibrotactile stimulus and by comparing it with an input signal generates an error signal driving the transducer. In an open loop active drive implementation, an input signal is shaped into a driving signal of a form designed to produce a desired vibrotactile response. The tactile interface adapts flat vibromotor transducers used as a silent alarm in cell phones for vibrotactile application. The adaptation involves means of fastening vibromotors to the skin implemented by adhesive tape, adjustable elastic band or specialized glove. A surround button is used for fastening vibrotactile transducers under tight fitting garments such as flight suits
