Intuitive Projection Display System Supporting the Manipulation of Dual Laser Pens

Ching-Sheng Wang, Ding-Jung Chiang, Chien-Liang Chen, and Hsin-Chueh Chen
Abstract—The combined use of computers and projectors in delivering multimedia presentations and in teaching is very common. However, the common operating tools used to deliver presentations such as presentation pens or mice either have limited manipulation functionality or are less convenient, and it is difficult to perform functions such as zooming, rotating images, and writing. In addition to allowing users to move freely in space to remotely perform functions, the laser pen manipulation system proposed in this paper can also perform the writing functions of a laser pen. Moreover, the system can also support the simultaneous use of two laser pens to realize a touch mode similar to that of a tablet computer, thus achieving an intuitive projection display manipulation experience.

Index Terms—Intuitive, laser pen, laser pointer, projection.
