A wearable tactile display device is disclosed wherein two or more vibrating stimulation pins can be located close to each other in one plane by means of the underlying vibratory actuation piezoelectric bending elements arranged in a cantilever configuration partially overlapping over each other as another set of planes. Further, optionally and in addition, the plane in which the tips of stimulation pins protrude may be a curved surface providing with the ability to comply with a curved human body part such as a finger. According to an aspect of the invention, vibratory stimulation can be achieved at close spatial resolution by advantageously reducing the space between adjacent stimulation pins through their ability to engage with different adjacent piezoelectric cantilever bending elements when they are placed at different planes. According to another aspect of the invention, vibratory stimulation can be achieved at additional closer spatial resolution by advantageously using the geometrical space between adjacent piezoelectric cantilever bending elements when they are placed at an angle to each other. The programmable controller employed in order to program the pattern of stimulation pin vibrations can be advantageously used for generating different amplitudes and frequencies of vibration. |
