D-Ruler / Ruler-Projector Drone


D-Ruler is a new measuring tool, designed for building purposes and decorating exhibitions. With simple principles of optics, the projector shows data of a ruler on the wall or ground. It means you can get information of targets about length, angles, and distance immediately. During a construction process, it is difficult for workers who need to frequently go high on a ladder and hold a conventional long ruler to measure. The data on the ruler is also hard to read. However, D-Ruler shows a ruler on wall and enlarges the data. This lets workers read it easily. Additionally, D-Ruler integrates several common measuring tools into one.
