INSTRUCTION DESCRIPTION · TECHNICAL FIELD OF THE INVENTION The technical field of the present invention is to provide a multi-person multi-touch treading interaction system, in particular to the human body conduction principle, electronic signal, and assembleable Circuit system, stepping on the mobile tracking system. [Prior Art] In a family living space or a smaller exhibition environment, we often want to be able to detect the location of users in this space and the interactions between users. Understand the user's possible movements and the atmosphere surrounding the communication between users. In recent years, the development of interactive technology has been handled by computer vision technology and has achieved 'computer' technology. After years of research, it has matured, especially the research on digital camera detection image engine. It is too numerous to enumerate. The common position tracking technology is a camera-based image movement tracking technology. It is the most common way to detect the position of the imagery, that is, the system. - Some surveillance systems and multiple cameras to avoid monitoring dead angles, and to perceive the network to integrate the camera and sound sensing or its domain to slap on the soft and hard body. Behavior at different locations. By relying on the fine-grained images of the video recorders, there is often no precision in the placement of the camera' and most of the research is to track the image movements in an open and unobstructed place, but between the users The interaction relationship is difficult to judge by factors such as angle, obscuration, overlap, resolution and so on. [Summary of the Invention] The purpose of this month is to provide a multi-person multi-touch treading interactive system. It is the first to develop the pedaling secret of 201030568, integrating the human body conduction principle, electronic signal, assembleable circuit system, and stepping on the "(4) . This material provides a human-and-loop interactive space-aware side and also provides human-to-human interaction detection. The object of the present invention is to provide a -_man multi-control stepping silk secret, which does not require image recognition and tracking technology, uses electronic signals and circuit systems to simultaneously track the position of many people to step on, and can handle many people The signal of contact between human bodies. The object of the present invention is to provide a multi-person gambling pedaling interaction to achieve the reading. In addition to the tracing position of the multi-person treading, it is also possible to contact the body of the copper multi-person. Together with the formable circuit system, the size specifications can be made according to the size of the secret area. In order to achieve the above object, the multi-touch multi-touch pedaling interaction is purely by the front projector, its projection and the ground; the electronic signal consists of an array of signal lines, each signal line is responsible for a signal transmission, and set The horizontal axis, the vertical axis and the oblique angle; the receiver is disposed on the vertical axis and the oblique angle of the horizontal axis. When the user touches the contact signal line, the signal line transmits the signal to the receiver through the human body (conductor), and the computer The collected signals are used to interpret the interactive situations touched by the users; an electric scorpion's singularity of the singularity of the singularity of the singularity of the singularity of the singularity of the singularity of the singularity of the singer and the output of the projected image of the front projector. [Embodiment] As shown in the figure - the 'tear-projection mode' is hidden under the foot of the _-type signal u, each signal line 14 is responsible for a signal transmission, each user 12 has a separate receiver 13 contact, when The user touches the floor on which the array signal line 11 is placed, and the signal line transmits the signal to the receiver 13 through the human body (conductor), and the computer 15 then interprets the interactive situation touched by each user 12 by the collected signal. In this way, each user's 12 gestures or actions can be clearly identified 201030568 and will not interfere with each other. The multi-person multi-touch treading interactive system provided by the present invention comprises: a front projector 16 projected on the ground; an array of signal signals 11 composed of an electronic signal, each signal line 14 Responsible for a signal transmission, and is disposed on the horizontal axis, the vertical axis and the oblique angle; a receiver 13 is disposed on the horizontal axis, the vertical axis and the oblique angle. When the user touches the contact signal line 14, the signal line 14 will pass through the human body ( The conductor transmits the signal to the receiver 13, and the computer 15 then interprets the interactive situation touched by the user 12 by the signal collected by the Φ; a computer 15 which intercepts the interaction touched by the user by the signal collected by the receiver Situation, and control the output of the projected image of the front projector. As shown in FIG. 1 and FIG. 2, the electronic signal is circulated to the human body, so if two users 21, 22' connected to the receiver of the number are in contact with each other to generate a path, the two persons are on the floor. The signal transmitted by the signal lines 11 of the two columns 25, 26 is simultaneously received by the receivers 13 of the two rows 23, 24. With such a principle, we can determine that the two users directly touch each other. Interactive information. The signal line arrangement is transplanted onto the assembled mat floor. And the receiver 13 is also placed on the combination pad, and each of the combination pads is connected to the receiver 14 of one of them. When the user steps on, the receiver and the signal line form a path by the user's stepping on. The invention adopts a "combination" floor to allow the future floor area to be expanded and changed according to the application needs. On each combination pad, we design the circuit in advance, integrate all the receiver signals through the switch, and work together with each set of horizontal axis and vertical axis and bevel circuit while splicing the floor, as shown in the figure. Three are shown. In Figure 3, in addition to transmitting the signal line on the horizontal axis and the vertical axis, there are also the received signal lines connected to the receiver and the transmission signal line in the oblique direction 201030568. (4) Distribution of different receivers. Can be specific to each other; fine. So we divided the mats into four types, with different circuits, so that the receiving signal lines on the mat are connected to the single-receiver, and the path that can be connected to other receivers is transmitted to the next stack. This more flexible way allows us to design the arrangement of the receivers on the floor for different applications, to touch each other in different directions or in different areas. In addition, because the user talks about the combination, it is not directly contacted, usually through the layer of shoes, • the signal strength will be weaker than the direct contact, if in each application, there is a need to make the strength stronger In this case, the metal conductor can be placed on the combination pad connected to different receivers to allow the user to touch 'or connect the wires directly to the user to achieve the effect. Determining the stepping area: As shown in Figure 3, the signal is received by the receiver, and depending on the frequency, it is known as the signal line from which horizontal axis 42, vertical axis 41 or oblique angle 43 on the floor. If the received signal strength is greater than the threshold value, it is determined that the signal line is touched by the user, and if the user is not touched, but the distance is very close, the signal strength will rise slightly. So on the horizontal axis 42 and the vertical axis 41, we define the contact signal line that is continuously contacted as the user's contact range, and use the edge and its neighboring signal strength as the internal difference method to find the position where the threshold value is located, Adjust the size and position of the contact range. By cross-matching the contact ranges of the horizontal axis 42 and the vertical axis 41, a plurality of possible tread zones are obtained. In our installation, a beveled 43 signal line is set, and if the intensity of the bevel signal intersected in the possible tread area does not exceed the threshold, it is removed from the possibility. In this way, the possible treading area is reduced, so that when the user is followed, there is a smaller chance of misjudging. 6 201030568 User tracking and contact judgment: Since people walk on the ground with their feet, unless they are clear, they must be at least at the time. There is a foot touching the ground. Using this principle, we carry out the treading of the marriage. - At the beginning, when the user steps into the floor, because of a new stepping area on the edge, it is regarded as the foothold of the new user' and there is a number of receivers in the area that receive the signal exceeding the gate number. Multiply ' represents the identity number of this user. Next, we will measure whether there is a stamped area with the same footing number as the original foothold within a certain range, and if any, the nearest one is judged to be the next step of the caller. After knowing the user's next step, if the stepping area of the original foothold disappears, move the foothold to the next position, and then return to the previous step to continue the process of tracking the program. Regarding the judgment of the user's _ mutual contact, our prescription is when the two users approached. If the respective identity numbers become the least common multiple of the original two identity numbers, it is judged that there is an event of mutual contact. The invention can be assembled to any size according to "the size of each piece of the combination pad is 3 〇 square centimeter and the thickness is about G. 5 cm. In the future, the module will be tilted towards the side, including reducing the number of signal lines, simplifying the complexity of the installation process, beautifying the appearance of the combination pad and increasing the waterproof function. It is expected to be the home and the merchant. Board decoration material shot. The system is quite extensive, for example: SmartHome, which allows the general floor building materials to give sensing and interaction _ function; also _ home security and medical care, establish a new security safety mechanism or instant Tracking objects on the floor (four) Lin, in addition to enhancing the current security surveillance Wei function and can eliminate the camera corners and loopholes and other shortcomings.
