A smart pen deciphers Braille characters. But participating fully in digital life remains a challenge for those with no or limited vision.
Enter a New York-based research team and its sparkling idea. The team’s square display contains 100 evenly arranged circular silicone sheets, each measuring 2mm in diameter.
The sheets can be made to pop up within 0.24 milliseconds and form Braille characters by triggering targeted mini-explosions – facilitated by the combustion of oxygen and butane contained in underlying tiny channels.
A process that can easily be reversed by applying a vacuum. Unlike electromechanical systems, the structure is hermetically sealed, providing resistance against dirt and liquids.
Innovative glasses help blind people avoid collisions and a smart vest safeguards blind dogs.
