As long as the user waves his arm without the help of other equipments, our system can automatically recognize the hand gesture and make suitable sound. In order to achieve depth camera's detection of hands movement,this paper introduce the depth imaging technology Light Coding and bone tracking technology to obtain the actual position information and hand movement information of the human body. Feet movement detection uses sensor technology, different stampede strength outputs different digital number after AD conversion so that the intensity can be controlled. A series of experiments show that the system has good fluency and practicality and increased the fun of playing instruments.展开更多

The hardware part consists of sensor, memory chips, USB, etc. , which is responsible for capturing original signals from sensors. The software part is a virtual oscilloscope based on LabWindows/CVI （C vitual instrument）, which not only has the functions of traditional oscilloscope but also can analyze and process vibration signals in special ways. The experimental results show that the designed system is stable, reliable and easy to be operated, which can meet practical requirements.展开更多

In order to make it easier to adjust car′s real-time body posture, it is necessary to design a real-time data acquisition system, thus reducing the number of casualties in normal driving. A brief account of the development status of data acquisition system at home and abroad, and the concept, principle,function of virtual instrument platform are given. The advantages and disadvantages of the data acquisitionsystem, based on LabVIEW in different methods of data acquisition, are analyzed and compared, and put forward some improvements and optimization, so the real-time data acquisition system can meet the requirement of adjusting the state of the vehicle, improving real-time of data acquisition and processing. Finally, it indicates the development direction and prospect of data acquisition system based on LabVIEW.展开更多
