Magical machines for the disabled

Just eyelid or frown or inhale or blow lightly, people with severe disabilities such as blindness, dumbness, deafness, paralysis of both hands . will be able to move and control household items, even Releases more complex activities thanks to the magical machines built exclusively for them. An exciting technology has opened up new horizons for all those who are having difficulties in observing, hearing, walking .

Disabled without disability

As an official in government, David Bristone is completely incapable of writing or typing text due to sequelae of cerebral palsy at birth, making his hands useless. But not so that he could not complete his job well. Technological advances have brought him new arms. Now, sitting in front of a word processor called Dragon Dictate, wearing headphones and microphones, Bristone starts working. He clearly read the words one by one, whereby each line of words appeared on the screen. Suddenly Bristone found a spell and blurted out "amniotic". As if understanding the meaning of the word 'am', the machine automatically reviews the text that has just been edited. On the screen showing 5 possible alternative words, Bristone chose the third word and issued the command. Previously incorrect writing was quickly revised. This word processing machine helped him draft thousands of necessary documents.

Many such marvelous machines were born to serve the 'consumer' needs of the disabled. Currently, these machines have been relatively popular in the disabled community in the US and in developed countries. And naturally, new computers, lasers, materials . and the idea towards unfortunate people is the foundation of revolution in this area.

Disabled people practice to integrate with life.

People paralyzed with both arms and legs can move with a wheel-controlled wheelchair invented by British and American engineers. This medium works by tiny microphones pointed in the ear and blocked by external sounds with a button. Users only need to move the tongue to disturb the air in the oral cavity, change the pressure and create a separate movement signal. The microphone will receive those signals and send them to the computer, from which the computer transforms into commands to control the vehicle.

Not only is it easy to move, people with limbs can also manipulate all actions from simple to complex quite comfortably thanks to a machine called 'sniffing and blowing'. The machine is also computerized, just blowing a light into a pipe, the user can turn on the TV, switch channels, call friends, play video games or take care of plants. Recently, scientists at Germany's Aachen Technical University announced that they have successfully built a smart wheelchair to help "effectively" support people with severe disabilities. The car is fitted with a special camera, directed at the person sitting on the vehicle. This camera can capture 40 images per second, connected to an integrated computer with identification software, can analyze every change of facial muscles and thereby turn into commands that are consistent with the owner's response multiply. And so, the person sitting on the car just frowns, smirks or eyelids . can easily command everything according to his own will.

After an accident, Ms. Eileen Carlton, 65, of Massachussett state lost her ability to pronounce. Thanks to the visual information machine, she can use images to place sentences and express ideas, which can often exchange information with family and friends. Mr. Bill, her son, exclaimed: 'Modern devices have opened up to my mother a whole new world. Thanks to the help of this wonderful machine, my mother can express what she wants to say. So instead of playing crossword games, my mom used images on computers to inform us that she was visiting her neighbors or shopping. My mother regained control of her own life. '

Most modern, convenient and most impressive is probably a car designed specifically for the disabled. Mr. Charler Krauthammer, paralyzed from the waist down after a traffic accident 19 years ago, currently uses one of these vehicles. The car is fitted with sliding doors, with remote control pedestals, users do not need to leave the wheelchair can still move into the driver seat. All subsequent operations are performed manually. The steering wheel is horizontal, it is easy to control without much effort when turning left or right. Want to increase gas or brake, just use your left hand to gently flick a lever to stimulate the vacuum pump to work outside the door or inside the car!

An expensive but humane technology

The word processor Mr. Bristone is using is priced at $ 9,000. Eileen Carlton's visual information machine costs $ 18,000. Krauthammer's Dodge Caravan special car is priced at $ 53,000 . Not a curiosity or an excuse, they are just a few of the numerous technical applications for hundreds of millions of disabled people. on the world. Mr. Jane Galvin, Director of Washington National Rehabilitation Hospital commented: 'The last few decades have been the booming period of high-tech equipment for disabled people. And it's hard to imagine what will happen in the next 10 years. ' And Mr. Guilaume Bonirface, Production Manager of the company specializing in the production of disabled equipment Otto Bock, Germany, said: We do everything for the disabled. A major breakthrough in this area recently is the continuous improvement of power as well as the minimization of microprocessors installed in the machines. Also add pre-programmed micro-control processors to significantly improve the smart element of the device. They will create rare possibilities, help handicapped people overcome many seemingly insurmountable obstacles to integrate ordinary life.

The main drawback of most devices using new technology is that the price is quite high due to the small market size, making it impossible for any disabled person to own them. In addition, the complexity of machines, vulnerability, unpopularity and maintenance is also a pressing issue to be addressed. Even so, in front of these miraculous capable machines, no one can deny the achievements of modern technology and a revolution is taking place to draw the handicapped people closer to ordinary people. is irreversible. Of course, there is only close coordination and lofty sacrifice of researchers, scientists, doctors, insurance companies and governments who, for these reasons or another reason to suffer unhappiness, can become more free and independent.
