Abstract
A method and device for improving the detection of a vibrotactile stimulus. Such method may include the steps of temporarily altering the threshold of vibrational detection prior to the onset of a vibrotactile stimulus. This allows the vibrotactile system to achieve improved detection of the intended vibrotactile alert or communication stimulus without necessarily increasing the vibratory displacement amplitude of the stimulus. A corresponding enhanced vibrotactile transducer device is able to produce, over a wide frequency range, or at multiple frequencies, a vibrational stimulus against the body of a user.
