Dance Enhancer
From: IEEE Spectrum - 05/2017 - page 17

There's a reason why terrible dancers are said to have two left feet. But
feet aren’t the only things that can make a dancer look clumsy or cool. A
team of engineers and designers from, Tokyo has created the Groove, a glove
that translates the movement of a dancer’s bands and fingers into signals
that cause the wearable device to light up. Each finger has bend sensors, and
there’s a pressure sensor and accelerometers in the palm. The Groove app uses
data from the sensors to determine the pattern of light created by the 50
LEDs on each glove. The team showed off the device at the South by Southwest
(SXSW) Festival in Austin, Texas, in March.
