[Abstract]:With the wide application of multimedia office teaching, the traditional mouse and low-end remote control products, which are the key interactive equipment of projection screen, have the disadvantages of inconvenient writing, low smoothness, limited range of use, etc. So that the user can not do a good real-time derivation calculus, record tagging and other activities. Aiming at the practical problems in multimedia application, this paper designs a more humanized wireless pen-type interactive system to meet the writing habits and enhance the interaction between users and audiences, which has the value of market promotion. The wireless pen-type interactive system designed in this paper is based on the research of the domestic and foreign wireless gesture track recognition technology, adopts the CC2541 wireless chip, carries on the data transmission through the low-power Bluetooth BLE protocol, the power consumption low performance is good, the adaptability is strong; Using MPU6050 sensor chip, accelerometer and gyroscope are integrated in one chip, which has high integration degree, effectively avoids the difference between axes, helps to reduce the area of circuit board, brings in data processing unit, and helps to solve attitude information by data fusion. With host computer display software, rich function, easy to use. The main work accomplished is: (1) analyzing the development status of related products and research achievements at home and abroad, comparing several common wireless gesture locus recognition techniques, analyzing the advantages and disadvantages of the technology, choosing the inertial sensor positioning technology. Compared with the mainstream wireless communication protocol, we choose low-power Bluetooth protocol, select CC2541 as the core chip of the system, and choose MPU6050 as the sensor chip, in combination with the practical application requirements, we choose CC2541 as the core chip of the system and MPU6050 as the sensor chip. The RF wireless communication, sensor, power management, interaction, clock and other module circuit schematic diagrams of RF wireless communication, sensor, power management, interaction, clock and so on are designed by using quaternion method as the attitude calculation method. The drawing of PCB board diagram is completed, and the hardware object is obtained by welding. The basic debugging is carried out, and the hardware function is verified. The system software program is developed under the environment of IAR EW for 8051. The program of data acquisition and processing at the transmitter and wireless transmission is completed, and the program of wireless receiving hid communication is completed at the receiving end. The program of attitude calculation is optimized, and the display system of multi-function host computer is designed in Visual C development environment, which is convenient for writing and drawing.) the joint testing of hardware and software functions is completed. The application effect of system software and upper computer software is tested, and the usability of system hardware and software is verified.
