Vision Based Laser Pointer Interaction for Flexible Screens

In recent years high quality interaction devices have become very popular in our environment. The industries are also currently undergoing rapid change and various technologies have been explored to enable these capabilities. Projection systems using beam projectors and laser pointer became the ubiquitous infrastructure for command technology. Group meetings and other non-desk situations require that people should be able to interact at a distance from a display surface. This paper presents new interaction techniques that use a laser pointer to directly interact with display on a large screen. The camera is subsequently used to detect the position of the pointing device (such as a laser pointer dot) on the screen, allowing the laser pointer to emulate the pointing actions of the mouse. The laser pointer will behave as a active point on the projected display where the user can interact. This vision-based system is augmented with a natural interface that enables the user to interactively...
