Touchscreens may have kicked-off a mobile computing revolution, but they didn't do much for the visually impaired. OwnFone, which launched a customizable mobile phone for kids and the elderly back in 2012, is now offering its stripped-down handset with braille or raised text contact buttons. The 3D-printed hardware lets you select up to four contacts that can be assigned to the device, making it ideal for emergencies and people who need to stay in touch with family or carers on a regular basis. It's available right now for a base price of £60, plus an additional monthly charge of between £7.50 and £15.00 per month -- depending on how much call time you want or need.
