The EyeRing features a 3D-printed ABS nylon outer housing containing a small VGA camera unit, a 16 MHz AVR processor, a Bluetooth radio module and a 3.7V Li-ion battery
The user points the ring at an object, tells the system what kind of information is needed via a microphone on the earphone cord and then clicks the button on the side of the ring unit to activate the camera and send a photo to a Bluetooth-linked smartphone for processing
The EyeRing system features a finger-worn camera module and wirelessly connected smartphone that provide a visually-impaired user with aural feedback on objects captured by the lens
The EyeRing's could also allow visually-impaired users to "read" text in non-braille books
Generally speaking, the vast majority of augmented reality applications that enhance the world around us by overlaying digital content on images displayed on smartphone, tablet or computer screens are aimed squarely at the sighted user. A team from the Fluid Interfaces Group at MIT's Media Lab has developed a chunky finger-worn device called EyeRing that translates images of objects captured through a camera lens into aural feedback to aid the blind.
