US Patent 11538373 Interactive projection system and interactive display method of projection system

The disclosure provides an interactive projection system and an interactive display method of the projection system. The interactive projection system includes a biologically-modeled housing, a first projection device disposed inside the biologically-modeled housing and an interactive sensing device, and a controller. The biologically-modeled housing includes a light-transmissive curved projection area. The first projection device projects the first physiological image onto the curved projection area. The interactive sensing device obtains the input signal. The controller is electrically connected to the first projection device and the interactive sensing device to identify the input signal and obtain user instructions. The controller controls the first projection device to project the second physiological image to the curved projection area according to user instructions. The first physiological image and the second physiological image display the physiological features corresponding to the curved projection area at a position on the biologically-modeled housing.
