Special Devices For Blind And Visually Impaired Persons

Blind and impaired persons need special support to perform their daily chores. When they walk or spread their hands to reach out to something in the distance, they may mistakenly touch an object that can cause harm. For example, a blind may fall into a drain if he didn’t know much about that particular area. This is why construction companies must use truncated dome mats that comply with ADA requirements for a detectable warning on curb ramps. Today, several special devices are available for people with visual impairments.

BrailleIt is a technique developed in the 19th century to help blind persons to read using a point system of writing. It includes patterns of raised dots represent letters and numerals the person can touch and feel the character. Years after its invention, the braille system has been improvised with the help of modern technologies. A computer-driven braille printer is a good example of a device inspired by braille.

Truncated dome matsThese mats are an essential device used in commercial and public places. According to the Americans with Disabilities Act, infrastructure companies are required to use truncated dome mats in their projects. These bright color materials are used for warning and assisting blind and visually-impaired pedestrians approaching intersections, vehicle areas, and hazardous drop-offs. Equipment manufacturers offer superior quality cast-in-place and surface applied, ADA compliant products. These mats are applicable in various projects, including g both concrete and asphalt surfaces, and they meet the requirements for a minimum depth for truncated domes.

CaneThis is the oldest but effective device blind people have been using for years. Apparently, this is a simple walking cane that assists the person while walking or detecting an object in the proximity. The user holds one end of the stick and spread out the other end that will touch truncated dome mats nearby. He will tap the stick on the surface and determine whether it is dangerous or safe. If he has suspicion that something is wrong, he will change his mind.

Truncated dome mats also provide surface applied truncated dome mats with peel and stick technology, making them super-easy to use. The pre-molded products are available in different materials such as fiber-reinforced composite, polymer-modified, cast iron, concrete & stainless steel as well.
