Save to active project

from the rehabilitation community; but are now being resurrected by a number of research laboratories that are incorporating technological advances into their designs. On the surface, all three techniques world appear to have merit and be feasible; yet, significant problems exist. The diversity of the control characteristics has made it impossible at this time to clearly analyze the shape, size, and surface finish of the controls, let alone make appropriate design recommendations. This problem will be examined further in a follow-up study.

Conclusions

In conclusion, many need on live of visually impaired people are unsatisfied. When design the appliance for them, must consider the learning and memories of people, not just consider operation process, function recognize. Some recommendations outlined from pilot test are restrictive from a visually impaired people point of view, rather than prescriptive. Continuous study will design best type of tactile interface as an efficient aid for visually impaired people. In any case, industrial designers are faced with a complex but challenging design problem.
