On-mouse projector: extended workspace using a mouse with a projector

Abstract

In this paper, we propose On-mouse projector, an interface that combines a mouse and a mobile projector. This system satisfies both portability and large information space and enables stable operation. The mobile projector is placed on the mouse and projects images on a surface in front of the mouse. The projected image presents a part of large information space and users can change the area to see by moving the mouse. The system is assumed to be used on a flat surface such as a desk and users can stably perform the same operation as the ordinary mouse operation. We created a prototype in which a projector is fixed above a mouse using acrylic plates. This prototype works in a standalone configuration by using a stick PC and realizes various operations such as object selection, object moving and image zooming.
