RING RULER: A Size-Adjustable Circular Ruler
The Ring Ruler addresses one of the most elemental structures in the physical world -- the circle. Up until now, the primary tool for creating circles is the needle compass, which pivots on a sharp, centered point. While this method has remained practically unchanged for hundreds of years, we believe there is a better way. We think the solution lies in a more natural, circular gesture. Why not use a circle to create or measure a circle? Using this method of an expandable/contractable measuring ring, we are now able to provide metrics that have never before been possible in a single tool -- namely DIAMETER, ARC LENGTH/CIRCUMFERENCE and even DEGREES.
