Abstract

The invention relates to a remote control interactive pen. The remote control interactive pen comprises a power supply, a laser module, a control module and a lens group, wherein a reflector is arranged in the lens group; the laser module comprises a visible laser module and an infrared laser module; visible light emitted from the visible laser module and infrared light emitted from the infrared laser module are reflected by the lens group and are emergent along the same optical axis; the visible laser module emits the visible light to enable an operator to accurately know the position and the moving locus of the interactive pen and freely control the movement of the interactive pen; the infrared laser module emits the infrared light; and a receiver detects the projection position of the infrared light and converts the position information into a mouse signal for the interactive operation. The invention further provides the receiver of the remote control interactive pen, wherein the receiver is provided with a narrow band pass filter which corresponds to the spectrum of the infrared light emitted from the interactive pen. The receiver has the advantages of reducing the interference of outer light and improving the work stability.

Description

【Technical field】 [0001] The present invention relates to a remote control interactive pen, in particular to a remote control interactive pen used in an interactive projection system and a receiver thereof. 【Background technique】 [0002] The interactive pen used in the traditional interactive projection system generally uses contact infrared light or single-mode visible laser technology. Stablize. 【Content of invention】 [0003] Based on this, it is necessary to provide a remote control interactive pen with better working stability. [0004] In addition, it is also necessary to provide a remote control interactive pen receiver with better working stability. [0005] A remote control interactive pen, comprising: a power supply, a laser module connected to the power supply, and a control module for controlling the laser module, the interactive pen further includes a lens group, a reflector is arranged in the lens group, and the reflector According to the emission directi...
