Wish there was a real-time measuring system that can automatically measure while you are drawing with your hand? Designer Giha Woo provides a solution.
Giha Woo’s concept design, the ‘Constrained Ball’ is a freehand drawing aid that helps the user draw perfect straight lines. But as a bonus, the device also measures the length of the line you are creating with its wheel. Not sure how effective it will be but certainly seems like a useful design in the absence of a ruler.
