Dot, a Smartwatch for the Visually Impaired


I think this is the most important and useful created smartwatch, a South-Korean start-up has created a new smartwatch for the visually impaired, the device is called Dot and it is based on braille technology, for those who are not familiar with this term, braille is a form of written language for blind people, in which characters are represented by patterns of raised dots that can be felt with the fingertips.

How it works

The Dot smartwatch will allow the user to get messages, read location directions, get time and set the alarm, the device has four sets of six dots that will raise up and get down in different forms depending on the received informations, allowing the user to feel them with his fingers, Dot have a speed of 100 movements per second, which allow the reception of 4 characters at one time, the speed can be adjusted for the beginners to get one characters per second. The device will be paired with the user’s smartphone via Bluetooth connectivity, then touch based informations will be sent using haptic technology.


The Dot smartwatch will feature a 10 hours battery life, (not very enough), but the company said that normal users will have to recharge it every 5 days, the device will be priced under $300, and it is expected to be around at the end of this year, you can check it and sign up for updates at the company’s website.
