Present-day wearable text-to-speech converters are also capable of object and face recognition. Such systems have been developed to assist with these tasks in patients with severe low-vision. ORCAM is a commercially-available eyeglass-mounted visual pattern recognition system capable of converting photographs of text to speech. It is comprised of a camera, a small belt-worn computer, pattern recognition software and a small audio transducer. ORCAM can acquire the image of a sheet of paper and read the text to the user through a small speaker adjacent to the ear. In addition, ORCAM can be trained to recognize faces and speak the name of the individual to the user. ORCAM can also be used to recognize everyday products after being programmed.
