Man-Machine And Coordination Design For Multimedia Demonstration Instrument

Currently, multimedia demonstration instrument of class teaching is an essential tool, for teaching. But how to demonstrate instrument optimization and how to locate the design engineering community is still a problem. Due to many teaching equipment design parameters on the irrational, imperfect design, resulting in more than 75% of teachers suffering from cervical spondylosis, frozen shoulder and other diseases. In this paper, based on the theory of ergonomics, the use of engineering techniques to measure the sample population, survey and computer-aided engineering design methods, the parameters of the multimedia presentation device modeling aided design and engineering models, specifically to complete the sample size of University Teachers data modeling, and model data through effective screening, the use of human-computer design and computer model testing consistency of the method, carried out coordinated multimedia presentation device of the machine design. From the simple to use, safe and efficient point of the college teachers to improve teaching and learning environment, and improve the overall structure of the demonstrator and function. The results for the optimal size of teaching equipment and design methods to provide a scientific basis for rational choice, to promote education reform and innovative design of the equipment. Measured by the sample population data modeling methods, 985 domestic universities to be selected in-service teacher sample of 100 people, of teachers standing position by two operating positions, the static and dynamic dimensions of the detailed measurements, obtained a sample of university teachers of human populations size of the database. Size of the data through the human body computing the mean and variance, the body size of college teachers completed data modeling, instrument size to demonstrate the optimal design parameters of the design basis. In addition, the survey questionnaires from the demonstrator operation starting the actual work environment, the demonstrator design of the questionnaire related to the design, output and feedback questionnaire results, and the depth of analysis of survey results and the Demonstrator site operation law teachers combine the Demonstrator ergonomic operating environment demonstrates consistency of design.The design of human-machine coordination, scientific modeling using population sample size of the database design elements and man-machine consistency to human engineering theory and design psychology based foundation, the overall complete multimedia machine coordination demonstration instrument design. Design elements include: the body size analysis, user interface design, functional user interface design, handset design, site design, equipment and systems operating area of the connector design, the overall size of the design and physical model design, the update part of the overall design, including re-positioning Demonstrator human security dimensions, and opened to increase dual-use lift chairs, innovative presentation screen, after computer information technology, simulation and model test results showed that: Classroom demonstration instrument parameters meet the operational status and consistency of design, operation rules consistent with human coordinate design project of the basic requirements. The main conclusions are as follows:1. Thesis body size of China's college teachers the data modeling part in the experiment to establish a set of typical body size of the database of Chinese college teachers, university teachers in China to solve the current sources of anthropometric data is imperfect, not based on body size design integrity, technical problems, to further standardize the data location of teaching equipment and scientific equipment to complete the rationalization of University Teachers provide a basis for design.2. By our experimental process, has been an example to demonstrate the instrument's ergonomic design teaching facilities, the size of the sample population data modeling and design of human-machine consistency of a combination of methods, from design concept of this method to solve the current design of the difficult problem of teaching equipment. The method is clearly positioning the device as an example to demonstrate the design of multimedia teaching equipment ideas. Coincide with the engineering survey and design of experiments, the method is scientific, reliable data, all kinds of teaching equipment for the future development and research methodology to provide the necessary information and technology;3. In applying the results of the data, using data from the sample population Consistency of measurement and human engineering design co-ordination combining design is completed based on the actual teaching of multimedia demonstrator machine coordinate design, its features are:(1) parameter design, the optimized size of demonstration instrument operating standards more in line with the teachers so that teachers in the actual working environment more comfortable, to design the basic requirements of human nature.(2) color: interface and button design, cover up the case and the cover design with different colors are used, giving an overall feeling. Quiet color design design choices, both bold sense of metal, wood have human feeling.(3) function: increased efficiency of the functional areas to improve teaching, while the frequency of the demonstrator by using a re-arrangement of the interface. Open the way to cover the design, not only meet the needs of humanity, but also reduce noise pollution, and rational use of limited space. Sliding microphone slot design, easy for teachers to use different height; function interface with different functions according to the frequency of the partition design, both for the convenience of the operation, also reduces the user to choose the time before the operation.(4) barrier-free design of the accessibility features, is a modern machine design an important manifestation of coordination. Teachers and teachers for older people with disabilities to increase seats, is the result of an innovative study design, both seats can be closed down and presented two design features that make the design more humane. Keywords multimedia presentation instrument data modeling coordinate design consistency Through detailed design, user-friendly design to further highlight the importance, reflecting the charm of technical education, to promote education reform and innovative design of the equipment.
