Under a remote collaboration, a teleoperated laser pointer is applied as an instruction tool to indicate real-world objects in a real work space. Ubiquitous devices mounting a teleoperated laser pointer make telecommunications smooth. However, this method has a difficulty identifying the indicated object in the situation that the laser-spot is occluded behind indicated object itself or other objects. In this paper, we propose a method, that is visualizing the light path of a laser with jetting mists along the light axis, to remedy the difficulty. It is expected that the worker can estimate the indicated object from visible light path laser pointer. We conducted experiments to evaluate our method on the condition that the instructor and the worker exist face-to-face. The result shows that the estimation accuracy of the position of a laser-spot occluded behind an object is improved with visualizing the light path of the laser.
