A "data glove" that recognizes various movements of a hand and can be used as a game controller, etc was exhibited at CEDEC 2018, which took place from Aug 22 to 24, 2018, at Pacifico Yokohama in Yokohama City, Kanagawa Prefecture, Japan.

The glove, "Grov," was showcased by Ryosuke Takada, doctor's student, Department of Computer Science, Graduate school of SIE, University of Tsukuba. He has succeeded in recognizing (1) the bending and opening of fingers, (2) contact between fingers and (3) held objects at the same time by using conductive fibers as sensors for the first time in the world. With conventional technologies, they are recognized separately.

In addition, a commonly-used commercially-available glove supporting touch panels is used as it is. So, the data glove can be very easily made at a low cost.

First, the user puts on the glove, folds and unfolds his/her fingers, uses the thumb to touch the tips of other fingers, etc to finish calibration in accordance with the shape of the user's hand. In the demonstration, dots corresponding to the joints and tips of fingers were displayed on the screen of a personal computer (PC). And the locations of the dots changed in accordance with the movements of the fingers.

In accordance with finger movements, green dots representing the joints of the thumb and forefinger move. Red dots represent the contact between fingers.

When I held three kinds of objects available at the site, characters corresponding to those objects such as "Red," "Yellow" and "Blue" were displayed on the screen. In a demonstration of the use of the Grov, when an object was held as if it was a gun and a finger was crooked, a bullet was fired from a gun displayed on the PC screen.

It is possible to recognize an object held by the hand.

When an object is held by the thumb and middle finger and the forefinger was bent, a gun is fired.
