Wenyu ^ people's growth rate 'in this month' is down, plus modern people like new and old-fashioned consumption, accounting for the female alpha month real type and for electronic levy. . The favor and dependence, electronic goods, and ^ f have also experienced explosive growth. With the help of this trend, various types of electronic products that can replace traditional workers and even surpass traditional tools will continue to evolve. The electronic drawing system, which is commonly used, is a digital tablet, which can be regarded as a large digital tablet. It includes a whiteboard, a computer, and a technical equipment. The trajectory can be drawn on the sensing whiteboard, and the coordinate value of the trajectory drawn by the user is continuously transmitted to the computer, and the trajectory drawn by the user is reproduced in the = position through the projection device connected to the computer. On the induction whiteboard, when the electronic whiteboard is generally used, it is necessary to go through the coordinate correction procedure to make the user's drawing obstruction coincide with the trajectory of the projection position, and the towel reaches a virtual feeling for the user to actually write, generally known. The electronic whiteboard uses the resistance method and electricity: the technology U is used to sense the whiteboard to record the trajectory drawn by the user. The known electronic drawing system can use the computer to record the storage. The user draws the 3 M424535's track' and can provide a review after the third person who is not on the scene, especially for children. With the use of the above known electronic drawing system, children can graffiti in the projection position or display On the screen, the use of paper can be reduced; however, 'known electronic drawing systems are electrically and electromagnetically arranged on a special whiteboard' because of the high manufacturing cost, making the price of the device difficult for the general consumer to accept, in addition, When the user touches the sensing whiteboard directly, the sensing device of the sensing whiteboard is damaged or invalid due to excessive force applied, and the user's drawing is not correctly reproduced; in addition, the electronic drawing system is only known to be painted. The second child who is absent from the child and the young child who is caring for the young child can only be consulted after the event and cannot achieve a wide range of interactive effects. [New content] In order to solve the above-mentioned known circular drawing system, the cost is high and the sensor device is easily damaged. And can't reach the wide interactive effect. The purpose of this creation is to provide an interactive Drawing system, system, optical recognition does not require direct contact with the sensing device to avoid damage 'and can achieve the effect of synchronous interaction, the main purpose of this creation is to provide an interactive drawing system.

The processing unit is the M424535 unit and the wireless transmission mobile track, and the processing is projected on a predetermined location unit to transmit the mobile operation: electrically connecting the projection unit, the image capturing and outputting unit, The image capturing unit is configured to capture the unit by using the projection unit, and the processing unit transmits through the wireless transmission wheel and reads A ^ ^ 1 - only shadow The image capturing device 2 is connected to the Internet through the Internet, and each of the hosts is provided with a wireless transmission; the surface is wirelessly connected to the corresponding first or -''---the hinge and image capturing device::: : transmitting... to receive or transmit the mobile track to the wireless transmission unit of the first or second image capturing device; ' thereby, the first and second projections and image captures are extracted The movement is performed, and at the same time, the host is transported to the host through the Internet, so that the moving track traversed by the corresponding capturing device is superimposed and the second projection and image positioning position are performed; Thereby, the two predetermined positions are corresponding to the two pre-picture contents, and have an interactive effect. The interactive mapping system that displays the creation of each other's picturebooks has the following enhancements: 1. Due to the spread of the various types of epidemic diseases in modern times and the symptoms are becoming more and more serious, (4) the children's interaction with children in the second Vietnam can be reduced. And through the interactive effect of this creation and other children using graphic painting or text depiction:: In the 豕: to enjoy the social interaction while avoiding the occurrence of infectious diseases; work and the interaction of 2 Graphic drawing or text 35 is enough to freely exert imagination with each other (4), in each other; two people: learning or playing games have more fun; ..., not official 5 钇 3, compared to the known electronic drawing system The touch sensing technology is used to record the trajectory of the sensing pen, and the image capturing unit only needs to capture the trajectory of each of the sensing pens without costing the sensing panel, thereby reducing the production cost and the reaction cost to the price. At the same time, it can also reduce the price; 4, because the sensor pen of this creation does not need to actually touch the object, but can cast the graphic text depicted by the six out, compared to the known Electronic drawing systems often: easy to damage the sensing equipment due to improper application, this creation can reduce the damage of the equipment and prolong the service life.
