Spectacles can hear what someone says and beam a translation on to the lens.
Foreign language dictionaries could soon be a thing of the past, after Japanese manufacturer NEC unveiled a pair of glasses that can automatically translate spoken words and phrases.
The system is designed to be compact and lightweight, so it can be comfortably worn for long periods and not to use too much battery power. The retinal display projects the text in the wearer's peripheral vision, enabling the user to maintain eye contact with whoever they're speaking to.
The Tele Scouter is currently still a prototype, although NEC plans to start selling the system to businesses next year. The Japanese manufacturer admits that the device's translation capabilities are limited at the moment, so it will market the device as a wearable, hands-free data display. NEC envisages that it could be used by engineers and technicians to view user guides or manuals while installing and repairing hardware.
A Tele Scouter system capable of supporting up to 30 users will cost around Y750 million (around £5.1 million), and NEC is hoping to sell 1,000 of these systems within the next three years.
a compact microphone and camera, which picks up the foreign-language conversation. This audio recording is then relayed to a small computer worn on the user's waist, which transmits the information to a remote server. The server translates the words from speech to text, and transmits it back to the glasses, where the translated phrase is then appears on a tiny retinal display, providing the wearer with a transcript of the conversation in their own language.
