SMART WATCH TO THE RESCUE OF THE BLIND PEOPLE FOR NAVIGATION

Albertorio is the co-founder of the company called Sunuand has developed (along with others) a wrist-worn gadget that can help the blind people in navigating easily through the busy streets. The watch uses a sonar sensor along with subtle vibrations to alert about the obstacles in the path.

A high-frequency ultrasound wave is emitted through the band. The strength of the reflection created when the ultrasound wave bounces off the objects that he encounters produces a vibration whose strength depends on the nearness of the object.

Since Albertorio himself is blind, he claims to feel more confident in moving around the busy streets of California. He, along with the co-founders of the watch, is hoping that the band can help the visually impaired or the blind people in easy navigation. There are more than 10 million blind people in U.S. itself which have made them begin their start-up at $299 only.

 

FEATURES OF THE BAND

Even though Sunu isn’t the first one for harnessing the sonar as a navigation tool for the blind people, the approach of the start-up looks promising and interesting. The market does have other products which use echolocation for navigation; but Sunu provides help to both- people who need help assistance all the time and people who can see but need assistance in some situations.

The band is meant to be worn with its sonar sensor positioned in front of the people wearing it. This would ensure that the person can avoid all kinds of obstacles in the busy sidewalks. The band can also be used for sensing doorways by spotting the gaps that occur between the vibrations, signifying varied sides of the structure. The band can also enable hiking and sense the edges of the trail.

The band is really sensitive to the response of the pedestrians and works with your mobile phone via Bluetooth. It allows you to adjust the intensity of the frequency and also keep a check on the battery life. The battery is supposed to last for four hours but since it isn’t always kept on, it can last for a day or two.

Sunu also can adjust the speed of your pace and use apps like Google Maps for guiding the directions towards destinations. The app isn’t necessary to have since the band can function autonomously without the use of a smart phone.
