“…In this article we propose a method of selectively stimulating only superficial mechanoreceptors. 7 Moreover, we show that it makes people feel a more realistic, finer virtual texture than possible by adjusting the stimulator spacing. The apparatus is simple, and we expect this idea to develop into a device to display varieties of tactile feeling.…”

“…An analysis of each modality reveals different levels of appropriateness for the construction of a tactile display. Four kinds of mechanoreceptors lay on the skin tissue [4][5][6]9], each at a specific depth in the skin. On the palm, the shallowest (Meissner corpuscle) and the deepest (Pacini corpuscle) mechanoreceptor are located below the surface by about 0.7 and 2 mm, respectively.…”

“…The skin can be regarded as a spatial low-pass filter for the surface stress distribution [9]. If we assume the human skin to be a uniform, homogeneous elastic body, we can calculate the attenuated pressure P z (k), at depth z in the skin, of a pressure signal P(k) with wave number vector k = (k x , k y ) by:…”

Tactation is the sensation perceived by the sense of touch, and is based on the skin's receptors. Touch is a common medium used by the general population and the sensory impaired. Tactile substitution can be used by the blind or deaf in order to: (a) enhance access to computer graphical user interfaces and (b) enhance mobility in controlled environments.The skin nerves can be stimulated through six types of receptors by mechanical, electrical, or thermal stimuli. Modalities, such as vibration and pressure, can stimulate these receptors. Advances in tactile communication using implementations of the actuating devices have been developed via several new technologies. These technologies include static or vibrating pins, focused ultrasound, electrical stimulation, surface acoustic waves, and other. This paper is a review of the state-of-the-art in the physiological and technological principles, considerations and characteristics, as well as latest implementations of microactuator-based tactile graphic displays. We also review fabrication technologies, in order to demonstrate the potential and limitations in tactile applications.

“…Auditory receptors may adapt to magnitude of acoustic signals and have no adaptation to the frequency of the stimuli. Auditory receptors can reply to almost any harmonics they are specifically ''turned on'' [3]. Therefore, rhythmic patterns are easily detectable through hearing.…”

Deaf and hearing-impaired people need special educational and developmental tools to support their social inclusion. Research in vibro-tactile pattern perception has shown that tactile memory could be a crucial aspect in coding and imaging semantic information for users with sensory limitations. This paper describes a simple matching game designed to facilitate the learning process of 27 vibro-tactile composite patterns (tactons) which can be produced with the Logitech tactile feedback mouse. The underlying assumption was that a particular framework and game intrigue would induce a player to mobilize the perceptive skills and deploy individual playing tactics to recall the tactons when progressing through the game. The performance of ten subjects using soundproof headphones was investigated in terms of the number of repetitions required to memorize and learn the mono-frequency, bi-frequency and three-frequency tactons, and in terms of the selection time needed to match the tactons in the game script. The analysis of the data collected indicated that the noviceto-expert transition was significantly above chance when the results obtained in the first and the last test sessions were statistically analyzed and compared. There was also a significant difference between mean selection times needed to match the composite patterns depending of their complexity in the first and the last test sessions. Upon learning and training within game, the tactons may be employed to assign alphabet characters or symbols to communicate textual or symbolic information.
