The ‘Smart rolling-ruler’ is a compact ruler and can draw a limitless line thanks to the flexible display that rotates 360 degrees and moves forwards like the caterpillar tracks. As it moves intuitively, the display shows the changing gradations and measurements. The smart device is marked in various units as well as the basic unit of centimeter, and has an automatic transformation function.
Additional features include unit conversion, a calculator, and a memo.
