Background technology
People is the sense of hearing, vision, tactile, smell, the sense of taste respectively there are five types of feeling.This five kinds are felt to constitute people to this
The cognition in the world, the sense of hearing so that this world is interesting to listen to melodious, and vision makes this world colourful, and tactile can be with let us sense
Know that the presence in the world, smell and the sense of taste can experience different tastes with let us.Although this five kinds are felt for people all
It is critically important, but many times, a certain kind is felt but realize the function that other are felt.For example, blind person can be touched with hand
Braille is read, and deaf-mute can mutually be exchanged by sign language.And the effect of tactile in this respect, in recent years increasingly by
The attention of domestic and international expert.
In many occasions, when the visual performance of people cannot temporarily play a role, the information that tactile is obtained is with regard to critically important.It is blind
People carries out reading of reading newspaper after blindness, using tactile touch braille, its life is made to be facilitated, and appoints in the fire-fighting for much having dense smoke
In business, fireman tends not to the position by visual determination landform or survivor, the information ability only provided by tactile
Task can be carried out.Although the mankind have just carried out the research of tactile early in 18th century, at present both at home and abroad for
The research of tactile still has limitation, unilateral.Generation for human tactile and operation mechanism can't be retouched accurately at present
It states.For the extraneous stimulation to application on human skin it is current there are many kinds of, but can not provide between various stimulations and the tactilely-perceptible of people
Detailed mathematical model.Many Tactile Test devices now, the often only environmental stimuli of single-element, such as electric touch, temperature
Spend tactile, water-jet tactile etc..And the structure of existing Tactile Test device is the haptic stimulus of single-point mostly, feels area
It is small, and stimulus intensity is non-adjustable.The present apparatus is stimulated using the water-jet tactile of array, and thoughts and feelings area is big, and can be to the temperature of jet stream
Degree and frequency are adjusted, and can effectively improve tactile fatigue phenomenon in an experiment.
