I know there are many folks out there that have a hard time reading a ruler or measuring tape when they are working on something that requires precision. A new concept product called Smart Fingers has surfaced that makes measuring as easy as using your hands.
The concept device goes on your finger and uses sensors that can measure the exact distance between the fingers. You can wear them on the same hand for small measurements or on different hands for larger measurements.
The device can even measure volumes and other dimensions that you need to take several measurements for. The results of your measurements are shown on a screen on half of the device. Inside the finger shape devices is a silicon material that lets them fit snugly on any size finger.
