Dot Pad tactile braille – The Dot Pad consists of 2,400 pins in a pixel-like grid that can quickly be set to be in up or down positions, forming letters in braille or easily identifiable shapes. That’s room for 300 braille glyphs, plus 20 more in a more traditionally spaced line below. Crucially, the device also integrates directly into Apple’s VoiceOver screen reading feature, making reading text, icon labels and even graphs or simple images just a tap away.
