Measure Accurately with your Fingers!

In older times, body parts like the arms, fingers and the hands were originally used as measuring devices.  But as people searched for new ways of translating accurate and precise measurements for building and construction, the measuring techniques of using body parts were later replaced by mechanical tools as this proved to be more accurate than the former.  Now, as technology becomes more advanced than before, it seems that we shall see the return of the old technique of measuring with our bodies but more accurately with the help of this measuring device...

Designers Choi Hyong-Suk, Jung Ji-hye & Yoo-Jin Park call this device the "Smart Finger".  It's basically a device consisting of two parts which can be inserted into two of your fingers.
The device works by sending out signals from one part of the device to the other.  The time travelled by the signal is then translated to a unit of length and showed on its LED display.
Because of the silicon on the finger slots, the device is flexible enough to fit any finger thickness.

Now, with the help of the "Smart Finger", you can now measure accurately using just your two fingers!
