285 million people worldwide are blind or visually impaired. For 20 years, there were almost no technology innovations for them. Existing Braille devices are heavy, bulky and expensive. DOT is the first Braille Smartwatch. It brings new possibilities to millions worldwide. The patented DOT Technology reduces size, weight and price by more than ten times compared to existing devices. DOT is available since late 2016 and as of March 2017, 200,000 units had been sold.
