Peri is an accessory that clips onto eyeglasses and translates nearby sounds into flashing lights.
The project was created for people with hearing problems, who sometimes miss out on what’s being said to them or on noises that could alert them to events occurring nearby. Peri is composed of four microphones and LED lights. The device’s circuits create a specific lighting pattern according to the loudest sound detected, and indicate the direction of the sound. The design takes inspiration from video games, which alert the player to nearby threats via a red glow. In games, however, they typically only appear when someone takes damage, while Peri could help the wearer avoid harm.
