Using a single finger, the 'Finger&Ruler' lets anyone measure with one hand swiftly and easily. With a quick swipe, the ring immediately displays the length of an object. The Finger&Ruler fits snugly around your finger so that you don't have to fumble around with a large tape measure.
Designer Shim Ha Eun created the high-tech ruler using simple concepts. A wheel rolls along the surface that you swipe on in order to feed dimension data to the ring. That information is then displayed on a crisp display at the top of the device.
The Finger&Ruler is especially convenient for people who only have access to one hand. Since a traditional tape measure can only be used with two hands, the Finger&Ruler works to remove restrictions and let anybody measure easily.
