Video projectors are often used to display presentations and are the most active mode
of communication in many business meetings. For a presentation to be more
interactive, the presenter generally draws figures and drawings on the projection screen
(e.g., whiteboard) or makes the marking on the projections itself. Drawing, writing, and
erasing mark-ups on a presentation is a manual and often untidy process.
This job can be made easier and more interactive by incorporating some level of
intelligence capabilities into the projecting device itself, such that marking the
presentation on-screen is managed by the projectors. In addition, saving the markups
would eliminate duplication of efforts and facilitate continuous improvement of the
The core idea of the disclosure is to provide a mechanism, utilizing an intelligent
microchip within the projector, wherein the projecting device is used to generate
markups, rather than the presenter drawing on the board. In addition, the changes can
be applied and saved to the active presentation.
Presenters can use pointing devices (e.g., laser pointers) to draw figures and sketches
on the projection screen. When the presenter points or draws on the projection screen
with the laser, the line(s) can become permanent, or can be erased by clicking on the
close button (provided on the projection by the projector).
A projector with smart technology operates in two modes:
