Smartwatch for the visually impaired displays information in braille


South Korean company Dot has developed a smartwatch that only displays information in braille, and is calling it a world first.
Intended to help visually impaired people lead independent and fulfilling lives, the Dot Watch is a streamlined smart device that offers information without hassle.
The design features a large circular face with a moving keyboard that relays braille text in real time.
While its main function is to tell the time and date, the watch can be connected to a smartphone application called the Dot Watch App, to receive information such as road navigation, weather notifications, calls and text messages, as well as social media alerts.
Made from silver aluminium, the watch utilises four electro-magnetic actuators that seamlessly relay information through textural dots. These automatically adopt the formations of braille numbers and symbols.
Dot claims that, while other braille displays read one line at a time, the display on the Dot Watch is an active one. It is designed to “pass by the user’s fingertips as if it were on a moving belt”, said Alex Lee, Dot’s sales and marketing director.
The technology is touch-sensitive, meaning that the second a user takes their finger off the final dot in a sentence, the braille formation changes to the next. The user is able to flip between messages by tapping the face of the watch or manually by using the side buttons and dial.
Currently the smart software supports English and Korean Braille only, but the company hopes to add braille alphabets for Japanese, Arabic, Spanish, French, German, Italian, Chinese and Hindu in the near future.
Dot claims that the innovative electro-magnetic actuator system in the Dot Watch could be used in a variety of public services and infrastructure, such as transportation, elevators and bank ATMs.
The brand is also doing research into creating a tablet device using the same electro-dynamic cell system, to display long format texts, similar to devices like Kindles and iPads.
