Further, if the amplitude of the surface of the metal plate 11A is increased, the "rough" feeling becomes smaller ("bumpy" feeling can be captured),
The smaller the amplitude, the greater the "smoothness" feeling (you can capture the "smoothness" feeling). Therefore, various tactile senses can be presented by setting the presence or absence of vibration on the surface of the vibrating means 12, the frequency and amplitude, and the temperature of the temperature adjusting means 13 to various values.

なる。Specifically, by increasing the vibration frequency of the vibrating means 12, it is possible to present a tactile sensation with less "rough" feeling. It is said that this “rough texture” can express the fricative consonant “s” in the linguistic information, for example. On the other hand, the tactile stimulus presentation unit 1 provides a sense of low temperature
By presenting to No. 1, it is possible to express a metallic material feeling with a small “roughness” feeling, and if presented at the same time as the vibration stimulus, unvoiced consonants can be clearly presented. On the contrary, by increasing the temperature sensation and lowering the vibration frequency of the vibrating means 12 to increase the "roughness" feeling, the voiced consonants "n", "m",
"Y", "w", "r", "g", "z", "d",
It is possible to express "b". Therefore, by storing the relationship between the material appearance and the linguistic information in the tactile information storage unit 16, various linguistic information can be presented.

る。A specific example of transmitting the sensibilities such as "cold feeling" and "warm feeling" generated by a normal person listening to music to the audio-visually impaired person is shown below. For example, the vibration frequency of the vibrating means 12 can be increased and the temperature sensation can be lowered to present a metallic material feeling, which can express "coldness" in the sensitivity information. In addition, by lowering the vibration frequency and warming the temperature sensation, it is possible to present a "rough" material feeling like wood, thereby expressing "warmth" in the sensitivity information. Is possible. Therefore,
By storing in the tactile information storage unit 16 the relationship between the tactile pattern and the emotional information such as “coldness” and “warmth”, the emotional information can be presented.

For example, the shape, size and arrangement mode of the metal plate 11A constituting the tactile stimulus presentation section 11, and the arrangement mode of the vibrating means 12 and the temperature adjusting means 13 provided in connection with the metal plate 11A are the same as those in the above-described embodiment. However, the present invention is not limited to this, and may be appropriately changed depending on the tactile sense to be presented by the tactile sense presentation unit 11 and the skin surface connected to the tactile sense presentation unit 11. Furthermore, when transmitting the transmission information via the tactile stimulus presentation unit 11, the type of language to be transmitted and the method of associating the relation between the transmission information and the tactile pattern are arbitrary, and may be changed appropriately. It doesn't matter.
