Although the foregoing description of the control method for the interactive projection apparatus of the present invention has been simultaneously described in the process of explaining the interactive projector of the present invention, for the sake of clarity, the flowchart is described in detail below. .

Referring to a sixth drawing, a flow chart of an embodiment of a control method for an interactive projection apparatus of the present invention is shown. In this embodiment, the interactive projection device includes a projector with wireless transmission and reception capabilities and a wireless interactive input device. First, as shown in step 501, an initial image is projected by the interactive projection device, and the initial image can be, for example, a teaching image; as shown in step 502, when the interactive projection device receives a wireless interactive input device (eg, a wireless interactive pen) In the case of an indication signal of the wireless controller, as shown in step 503, the interactive projection device determines whether the indication signal is the first indication signal, and if yes, proceeds to step 504, otherwise proceeds to step 509. When step 504 is performed, a plurality of data blocks (for example, a point name table) of a matrix arrangement of an On Screen Display (OSD) are started, and then, as shown in step 505, a plurality of data areas of the initial image and the matrix arrangement are synthesized. The block becomes the first composite image, and the first composite image is projected by the interactive projection device. Then, as shown in step 506, the interactive projection device may change the content of the data blocks according to the first indication signal to automatically randomly select one of the data blocks to display the selected specific data area. The block, for example, displays the selected specific data block in a white, flash, or the like manner. Then, as shown in step 507, the plurality of data blocks of the initial image and the changed matrix arrangement are combined into a second synthesized image, and the second synthetic image is projected by the interactive projection device. Finally, as shown in step 508, the memory module electrically connected by the interactive projection device automatically stores the second synthesized image.

On the other hand, when the interactive projection device determines that the indication signal is not the first indication signal, step 509 is performed. As shown in step 509, the interactive projection device determines whether the indication signal is the second indication signal, and if yes, proceeds to step 510, otherwise returns to step 503. When the indication signal is the second indication signal, as shown in step 510, a plurality of data blocks (for example, a scoreboard) of a matrix arrangement of an On Screen Display (OSD) are activated. Then, as shown in step 511, a plurality of data blocks of the initial image and the matrix arrangement are combined into a first synthesized image, and the first synthesized image is projected by the interactive projection device. Then, as shown in step 512, the interactive projection device may change the content of the data blocks according to the second indication signal, and the user specifically selects one of the data blocks in the specific selected data area. A corresponding selection count (count) is left on the block, and the selection count of each data block is calculated, for example, adding/subtracting points for the specific selected data block record, and is the upper right corner of each data block. Record the total score and proceed to steps 507-508.
