Electronic sidewalk block for a blind person
Field of the Invention The present device relates to an electronic sidewalk block for a blind person, and more particularly an electronic sidewalk block having a radio frequency RF card or an electronic textile to be placed in a sidewalk at regular intervals to guide visual handicapped people to walk through in safe. An RF card reader, might be installed in a walking stick of the visual handicapped people, drives or is driven by the RF card in the sidewalk block by the way of a non-contact method. In other words, the RF card reader receives data within the RF card in the sidewalk block by the way of the non-contact method, converts those data into voice signals, provides the voice signals to receivers of the visual handicapped people by the way of wireless or wire line, and guides the visual handicapped people to walk through the sidewalk, eventually.
Description of the Related Art Generally, there are two types of the conventional sidewalk block guiding visual handicapped people to walk through the sidewalk. One is Braille type sidewalk block and the other is an inducement-type sidewalk block. Braille type sidewalk block comprises of raised round marks meaning "stop" or "turning point", and the inducement-type sidewalk block comprises of raised rectangular lines meaning "go straight" to the visual handicapped person.
Conventionally, Braille type block or the inducement-type block, ("inducement block" in the following statements) are installed in predetermined places, such as a Road or a subway, where the visual handicapped people usually come and go. Therefore, the visual handicapped people use walking sticks or their feet to recognize the projection shape of the top of the installed inducement blocks to decide the directions, such as "go straight" or "turning point". Eventually, the visual handicapped people can go to any place where they want to go .
Fig. 1 is a perspective view of the conventional inducement block. The conventional inducement block comprises of Braille type sidewalk block having rounded projection 6 meaning "stop" and "turning point", and an inducement-type sidewalk block 8 having a rectangular projection line 3 meaning "go straight" to the visual handicapped people.
Fig. 2 is an example of the conventional inducement block. Braille type sidewalk block 6 or an inducement- type sidewalk block 8 is installed in predetermined places, such as a Road or a subway, where the visual handicapped people usually come and go. Therefore, the visual handicapped people uses their feet or walking sticks to recognize the projection shape of the top of the inducement-type sidewalk block to decide the directions, such as "go straight" or "turning point".
However, the top of the inducement-type sidewalk block installed in the place crowded with people is often broken or worn away. Therefore, the visual handicapped people can not recognize the projection shape by their feet or walking sticks. In more, the visual handicapped people have to decide their own way by the shape (circle or rectangle) of the top of the inducement block. Therefore, it is not easy for the visual handicapped people to recognize lots of variable status of the place where the conventional inducement block is installed.
In more, there are many cases traffic signals are moved or the positions of crossroad of road passengers are changed to another adjacent place. In such cases, the conventional inducement block should be re-installed immediately to make the visual handicapped people recognize the situation of the road. However, it is difficult to re-install the conventional inducement block immediately because of construction expenses.
Therefore, the visual handicapped people can not get correct information properly, which might give serious traffic accidents to the visual handicapped people.
