Fujitsu Bluetooth ring lets you write in the air
Fujitsu is continuing its push into wearables for the workplace with a prototype Bluetooth ring that lets users “write” in the air so they can work hands-free.
The gestural device goes on the index finger and can be used to write Japanese characters, Latin letters or numbers in midair. A linked smartphone or other Bluetooth mobile device with a Fujitsu app can instantly recognize numbers written with the ring with about 95 percent accuracy, according to developer Fujitsu Laboratories.
The ring can also be used to select items in a menu shown in a linked head-mounted display and to retrieve information from NFC (near field communication) tags.
