Abstract
An interactive projection system includes an electronic device, a projection device and an interactive module. The projection device is connected with the electronic device for receiving a first image signal generated by the electronic device and accordingly projecting a first image. The interactive module includes a processing unit, a storage unit connected with the processing unit for storing a calibration data, an image capture unit connected with the processing unit for capturing the first image and a light point image, and a communication unit connected with the electronic device and the processing unit for transmitting an absolute coordinate information computed and generated by the processing unit according to the light point image and the calibration data to the electronic device. An output signal is generated by the electronic device with the absolute coordinate information. Therefore, the present invention avoids the repeating image calibration and reduces labor cost and time cost.
