NTT Docomo Inc exhibited devices prototyped using a head-mounted display (HMD) at a trade show that Vuzix Corp organized April 25, 2014, in Tokyo.

At the show, which is Vuzix's second "Vuzix Developers Conference," NTT Docomo showcased devices that won prizes at "Develoer Application Contest," which was hosted by NTT Docomo and NTT Docomo Ventures Inc. Applications for the contest were accepted from November 2013 to February 2014.

Smart glasses for aphasiac people

The first prize was awarded to the "Otone Glass." It was targeted at aphasiac people, whose speaking, hearing and reading abilities were impaired due to a damage to the speech center of a brain caused by brain infarction or hemorrhage. It helps them read and write.

The Otone Glass takes an image of characters with its camera when the wearer blinks. The data is sent to a server and analyzed. The results are sent back to the HMD, which, then, reads out the characters.

The development of the Otone Glass started because the father of a member of the development team became aphasiac. The team is now developing not only the application software but also a dedicated HMD. And it is looking for a partner to commercialize the device.

Application for reading book on bed

The "smart life prize," which is for an application that can make everyday life richer and more convenient, was awarded to the "Ofuton Reading." It shows the text of a book as a scrolling ticker like an electric bulletin board. The HMD was developed to enable the wearer to read a book while lying on a bed.

The "best wearable prize" was awarded to the "HandCamera," with which photos can be taken only with a hand gesture. When the wearer of the HMD forms a shape such as rectangular and heart shapes with the fingers of both hands, the HMD automatically takes a photo that is trimmed in the shape.

Because the HMD requires a hand gesture to take a photo, people around the wearer can notice when a picture is being taken. Therefore, it helps prevent taking a picture without permission and protect privacy.
