Fujitsu Laboratories has developed a lightweight, compact wearable device that makes it easy to draw letterforms in the air.
Though it seems wrist-adorned and head-mounted displays (HMDs) are all the buzz as of late, Fujitsu is hoping to change that with their newly-revealed smart ring that not only allows for motion control, but in-air handwriting as well. Sure, HMDs are already helping to provide a hands-free workplace for operators, however they don’t make it particularly easy to select displayed information, input figures, jot down memos on workplace conditions, or perform other necessary tasks.
Fujitsu’s latest innovation lets wearers trace letters using their fingertip, while a built-in motion sensor translates those movements into usable characters. By “writing” in the air, users can then select menu options or make notes on photos that they take in the field — something which could certainly also come in handy during a tradeshow or while on-the-go.
“By applying proprietary technology that corrects the letterform tracings, Fujitsu has been able to improve character recognition accuracy, enabling recognition of everything from numbers to Chinese characters.”
Aside from its motion sensor — which features an accelerometer, gyroscope and magnetometer — a BLE module, a status display LED, an operation button, a sensor-processing MCU, and a battery (capable of lasting roughly eight hours) are all packed into the tiny device. In addition, there’s an NFC tag reader embedded inside that will enable a user to receive instructions with a simple tap. The company believes that as data from the object to be worked on can be easily selected in a hands-free manner, the performance of maintenance and other tasks is expected to be more efficient.
While still merely a prototype, Fujitsu is currently testing the real-world usability of the device with aspirations of practical implementation by early next year. Explore the ring in more detail here.
