The proposed multiple-point interaction technique realizes direct interaction and control in a virtual environment and presentation. The device for interaction is constructed on the basis of the infrared (IR) laser which is invisible for a human eye and does not interfere with the visual channel of a presentation, since there can be no coincidence of the color of the infrared laser and the visible object on the screen.The special designed optical scheme splits a laser beam into three with a small angle of divergence. As a result we receive the three IR spots on the screen.The coordinates of the laser spots received from the infrared camera are interpreted as a position of the (pointer) cursor after the mathematical processing which is displayed with the help of the projection system and can be interpreted as commands of the application control.
