These sensory substitution devices (SSDs) provide visual information from touch and sound to allow people with vision impairment to 'see' their surroundings. EyeCane is a flashlight-like device which transmits infrared rays to translate distance into tactile and auditory cues, allowing wearers to sense anything within a 5-meter range. The other device, EyeMusic, is a mini-camera connected to an app which translates the locations, colors, and shapes of objects into soundscapes which the brain can interpret visually. With enough training, blind people can identify pictures of people, and recognize the letters of the alphabet - all with the power of sound!
3. Assisted Vision Smart Glasses
These smart glasses are designed to enhance the vision of people with very limited eyesight. They are made up of two small cameras, transparent OLED displays, a GPS unit, a compass, a gyroscope, and a headphone. The data it receives can be used in many ways, and after it's processed by the system, important information is relayed to the user through the headphone. The best part is that these glasses come with an astonishingly low price tag!
4. Blitab
Nicknamed 'the iPad for the blind,' this device resembles an ebook, but uses little physical bubbles to display letters, opening up the possibility of viewing entire pages of braille text at once. This amazing device is able to convert a text file into braille, and can also read text aloud for you. What's more, the Blitab is even able to display tactile images, making it accessible for blind users who can't read braille.
5. OrCam
This brilliant device sits on the side of a pair of glasses, and uses optical character reading (OCR) technology to help users read printed materials, such as magazines, newspapers, products in shops, and road signs. It can also allow wearers to easily recognize the faces of friends and family. The device contains a miniature camera and computer, which automatically zooms in to locate the text on a page. If a user wants something read aloud to them, all they need to do is to point their finger at it, and OrCam will do the rest!
