Abstract

We proposed and developed a method to visualize the light path of a laser with jetting mists along light axis of a laser pointer. The estimation accuracy for the position of a laser spot occluded behind an object was improved when the light path of the laser was visualized. In this paper, we propose visible light path laser projector (VLLP) for remote collaboration. VLLP is equipped with a laser projector and a mist generator. With the laser projector, VLLP can instruct with not only a laser spot but also simple line drawings. Furthermore, we propose several VLLP application prototypes.
