Out of 285million visually impaired people, 95% cannot read. Now blind people can access various text data like messages, tweets, and books anywhere, anytime. A South Korean startup company may have finally found a solution. They created Dot, the first braille smartwatch, complete with shifting cells of dots. This inexpensive gadget could help the blind catch up to the age of smartwatches, the sales of which have increased 475 percent in the last year thanks to the Apple Watch. But it could also be used as an educational tool. One key feature of the Dot wearable is its cost. Unlike braille e-readers, which can cost thousands of dollars, the device is slated to cost less than $300 when it hits the U.S. market in December.
