The United Kingdom-based company 121 Captions, which provides communications support for people who have hearing impairments on a global basis, recently posted a one-minute video introduction to Google Glass on its website. The video introduces viewers to the Glass and offers a step-by-step tutorial about turning the product on and fitting it to a user. The company plans to follow up shortly with additional step-by-step videos as well as commentary from users. 121 Captions’ caption-streaming platform, 1CapApp, can stream realtime captions to Google Glass.
