A group at MIT is currently developing EyeRing, a camera designed to be worn around the finger. It would allow, for example, someone who is visually impaired to point at an object, take a picture with the EyeRing and send the photo via Bluetooth to the wearer’s smartphone. There, the object is identified for the user in auditory or visual form. Other potential applications could extend to children who are learning how to read. They could point at a word in a book and hear it read aloud by a Bluetooth-connected phone or tablet.
Big camera manufacturers like Panasonic and Samsung are already offering cameras that are capable of pairing with a tablet or phone. Currently, these cameras are mostly limited to sending a photo or video from your camera to your device where it can be pushed to Facebook or other social platforms. A product like EyeRing takes the smartphone/camera combo into new territory, no doubt with many useful applications.
