The Latest Guide Equipment For The Benefit Of Blind People

New York's tactile navigation tool company is developing a hand-held device. wearable devices The device detects obstacles by sensors, and uses vibration to remind wearers to avoid these obstacles. Developers say that the device called Eyeronman can not only help blind people, but also provide assistance to firemen and soldiers.

According to WHO statistics, around 285 million people suffer from visual impairment worldwide. However, even in developed countries, most blind people still use the standard white cane invented in 1921 to guide the blind. The Eyeronman device is a vest with sensors and signal launchers equipped with laser radar, ultrasonic induction and infrared induction. Laser radar is commonly used in driverless cars. Ultrasonic induction is the echolocation ability of animals such as bats. Infrared induction is the ability of the rattlesnake snake to detect the prey's electromagnetic radiation by sensing body temperature.

The system converts signals from these sensors into electrically activated polymeric materials. T-shirt Internal vibration. For example, an obstacle on the lower left of the wearer will cause the left lower part of the T-shirt to vibrate. Developers say the system can provide obstacle detection at a range of 360 degrees. Studies have shown that visually impaired patients use the normally visual part of the brain to process auditory information, suggesting that the brain is naturally plastic - it constantly adapts to the environment and forms new neural connections. Users of the Eyeronman device will use this plasticity to train themselves to familiarize themselves with the device.

Helen Keller, a deaf and blind writer, can perceive the concept of water through the flow of water from his hands, so that the blind can perceive and bypass a table by means of vibration alerting. The company's project leader, Rizzo, said. According to the introduction of the company's official website, the patented Eyeronman system also allows soldiers to use in smog and confusion. In the evening, because of the visual impairment caused by smoke or explosion, it is also suitable for police or firefighters to apply for on-site rescue. Rizzo believes that although some people have invented similar devices, no one can develop a platform like their R & D team to detect the shape of objects and allow visual impairments to perceive the body through signal processing.

Now, the system is still in the prototype state, but researchers have developed a new version. The input signal of the sensor will light the LED lamp on the T-shirt instead of the vibration, but the principle is the same. Not all sensors can work well in various environments, so developers need to find better and lowest cost sensors, so there are still many challenges waiting for them.

Sincerely hope that this device can be interviewed as soon as possible. Personally, it can help blind people walk freely, but the biggest problem is how to lower the cost, so that more friends with eye diseases can use it. More convenient, this device can almost be able to Eye replacement To perceive the world, if we can transform the image into brain signal after deeper development, then we can restore the environment to the blind, and enable them to feel the world in a real sense.
