An array jet tactile experiment device

Abstract

The invention discloses an array type jet tactile experimental device. The array type jet tactile experimental device comprises a rack shell (2) of a wedge-shaped structure and a screen (1) installed on the wedge-shaped surface of the rack shell (2); a plurality of cross beams (16) are installed below the screen (1) along a height direction; a plurality of nozzles (5) of which the spouts point to the screen (5) are fixed to the cross beams (16); the nozzles (5) are connected with pumps (8) for extracting fluid; the nozzles (5) are connected with coupling vibration devices (6) used for adjusting the frequency of jet flow; and the nozzles (5) are provided with heaters (4) for adjusting the temperature of the jet flow. According to the distance-adjustable array type jet tactile experimental device of the invention adopted, a tactile area is large, a tactile two-point limen measuring experiment can be carried out; and at the same time, a variety of kinds of tactile stimulus can be combined together, so that an integrated structure can be formed. With the array type jet tactile experimental device adopted, a tactile fatigue phenomenon in an experiment can be effectively improved.

Description

technical field [0001] The invention relates to an experimental device, in particular to an array jet tactile experimental device. Background technique [0002] Humans have five senses, namely hearing, sight, touch, smell, and taste. These five senses make up people's cognition of the world. Hearing makes the world pleasant to hear, vision makes the world colorful, touch allows us to perceive the existence of the world, and smell and taste allow us to experience different tastes. Although these five senses are very important to people, in many cases, a certain sense can fulfill the function of other senses. For example, blind people can read by touching Braille, and deaf people can communicate with each other through sign language. The role of the sense of touch in this aspect has been paid more and more attention by experts at home and abroad in recent years. [0003] In many occasions, when people's visual function is temporarily unable to play a role, the information o...
