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.
