Abstract
The cutaneous sensation can be used as a substitute sensory channel to transmit the information of objects to the brain. A conventional means of cutaneous stimulation is the mechanical vibration method, but it has many faults (the adaptation and the influence of enviroment). So, we explored the possibility of using electric stimulation as feedback signals at the man·machine system.
To begin with, we discussed the determination of appropriate stimulative conditions. the facter producing effect on stimulative sensation. On the basis of such findings, information processing tests were conducted. The dimension of electric stimulation consists of amplitude, frequency and space. Combining these dimensions, we formed multi-dimensional stimulational stimulation and gave it to the human beings.
Consequently, the maximum amount of transmitted information for two-dimensional input information was 3.6bits/symbol and for three-dimensional information was 4.5bits/symbol. Our studies have demonstrated that electric stimulation is more effective as a feedback signal at the man·machine system than vibratory stimulation.
