Bluetooth buttons help visually impaired find their way
A set of Bluetooth-enabled buttons called Pips are helping people who are visually impaired find their way. This is proving especially helpful with children who have vision problems.
Called Pips, these buttons can can be placed anywhere around the home and they flash and beep, to tell the user what they need to do. Once the button has been pressed, it turns off and activates the next Pip in the sequence.
The prototype was originally designed to help people with dementia manage their daily tasks. Once developed, Nominet, the company that designed it, realized it has wider uses.
The code and instructions for how to build Pips are now available online, so people can start experimenting with the technology.
