Now many public facilities and housing are designed for the special groups, which is a country, a city, the embodiment of the humanistic care to special groups, designed for the special groups, should be first defined as under the premise that does not affect ordinary people use can ensure that the special groups, and it’s convenient to make such as brailed buttons.
Button design for the blind, which is supposed to be the most popular design for the special population, and the form is quite colorful.
The most common way is to put Numbers and braille tags together on the same button, like S. It should also be the cheapest way to achieve this. But personally think that the problem is the border of the touch and press hard to grasp, do not understand the blind mode of operation, oneself just wants to feel there is the problem, if there is any misunderstanding at correct). Imagine a blind person touching a button area and trying to figure out how to make sure the Numbers look for patterns. Knowing the braille should be touched with some force, but avoid pushing the button. Whether it is easy to operate by mistake like this, it is easy about the blind to be in a more nervous state.
U and c are barely a type of design. The black area places the floor number and braille mark, and the button provides the operation. Such separation processing avoids the above mentioned problems. However, the comparison between the two also reveals a problem that U fail to consider the principle of intimacy. If you look at the layout of U, it is probably the work of an industrial designer who is too dedicated to “alignment”. Configuration is very uniform, but black area and button corresponding relationship, can’t be clear at a glance to see or find out, we should use “read from left to right” experience or a minimum repeat unit to the right operation. The design like c USES exterior matching to form a natural connection between the two, which is a relatively good design.
X’s design is more neutral, which ensures that blind people can recognize it, and also ensures that it does not increase the burden of recognition on ordinary people. It is also very beautiful. J and T is a person feel better design, made braille region and the entire panel the same raw material, and its corresponding floor button closely arranged, neither too much interference identification, ordinary people also convenient operation for the blind. However, T is slightly superior to J in the design of braille area. Braille is arranged on the same board for convenient extension and touch.
