Yanko Design: Go back into the history of measurements and we know that in the ancient times, body parts used to be the standard for measurements; hence ‘a foot’. The need for uniformity paved way for the metric and imperial systems that are now commonly used. However our basic instincts still make us want to use ‘a span’, ‘two finger spaces’ or ‘an arm’s length’; old habits die hard I guess! To resolve this and bridge the gap between digital accuracy and human approximations is the Smart Finger. It is a device that caps your thumb and forefinger (or any 2 fingers) and uses the signals relayed between the two finger points to calculate the measurement.
