On-mouse projector
Tomohiro Araki, Takashi Komuro · 2017
In this paper, we propose a system that combines a mouse with a projector and that allows users to perform peephole interaction, which enables stable operation in a wide workspace. In our prototype system, a mobile projector is attached above a mouse and projects part of the workspace on the plane in front of the mouse. The user can change the area he/she wishes to see by moving the mouse and can perform operations in a virtually extended workspace. We conducted an experiment to compare the methods of changing the displayed region and the cursor position when the mouse moves. Our results show that the method with the highest ratio of view transition to mouse movement, in which the workspace is not fixed to the real space, outperformed the other methods and was also highly evaluated by participants. Furthermore, the task completion time decreased with repeating trials with fixed target positions, which suggests that spatial memory is helpful even when the workspace is not fixed to the real space.
