Abstract
A multi-mode interactive projection system includes a pointing device, an infrared capturing device, and a projection device. A timing generation module of the pointing device generates several timing signals, and controls the pointing device to execute one light emitting mode according to one timing signal. A light emitting module of the pointing device is controlled by the timing generation module, and generates infrared in a light emitting time according to the executed light emitting mode. In a detection time, the light emitting time corresponds to one light emitting mode. The infrared capturing device periodically captures the infrared. A projection module is controlled by a background image and a writing image outputted by a host device, and projects the image to screen. The host device determines the light emitting mode and continuously captures coordinate points of infrared by the infrared capturing device in the detection time.
