体感手环控制幻灯片翻页方法及装置设计

The Method and Device Design of PowerPoint Slide Page Control with Somatosensory Bracelet

摘要:

针对课堂教学中教师需要手握激光笔遥控PowerPoint幻灯片翻页的问题,提出了体感手环控制幻灯片翻页的方法,设计了基于MPU6050传感器的体感手环教学控制装置,该装置采用体感无线手环和教学接收装置组成的无线数据传输控制结构,重点研究并提出了手势动作定义、手势信号感知与预处理和手势特征提取等算法,并通过该装置的设计和测试,进行算法有效性和准确率的验证。实验结果显示,系统能够有效识别向左或向右一挥的手势动作,能够可靠控制PowerPoint幻灯片向上或向下翻页,实现设计效果。

Abstract:

Aiming at the problem of teachers need to holding the laser pointer remote PowerPoint slide page up or down during the classroom teaching, this thesis presents a method to control the PowerPoint slide page by the somatosensory bracelet, and designs somatosensory bracelet teaching device based on MPU6050 sensor, which adopts the structure of wireless data transmission control system including the wireless somatosensory bracelet and the teaching receiver. The research focuses on the algorithm of gesture definition, gesture signal sensing and preprocessing, gesture feature extraction, and verifies the validity and accuracy of the algorithm through the design and test. Experimental results show that the system can effectively identify the gestures to the left or right, and reliably control PPT page up or down to achieve the design effects.
