Fujitsu has announced the development of a ring-like device that allows users to input handwriting; provided that they are used to writing with an outstretched finger. It looks to be a production line device, and is unlikely to be aimed at regular consumers; although there is no reason for it to reach the mass market.
The nameless ring is intended to be used with head mounted displays (HMD) like the Google Glass. Essentially, the company says that it is difficult to input text and impossible to select on screen options on these HMDs. The ring will function mainly as a pointer for any interface, while the handwriting input is for taking notes during work.
NFC enabled devices can be interacted with using a built-in NFC tag reader. This is meant to provide the ring and connected HMD with information on how to interact with the device. Naturally, this will require machines to have NFC enabled instructions in the first place. Which could be Fujitsu’s ultimate plan for building an ecosystem.
Fujitsu will be testing the real world applications of the ring device during 2015, although there is no plan for when it will be commercially available.
