Posture Correction Device Based on LabVIEW

In order to protect the health of people who often use computer, a posture correction device based on LabVIEW is proposed in this paper. The posture correction device consists of host computer and slave computer. Host computer is composed by graphical user interface (GUI) programmed by LabVIEW software in PC. Slave computer is composed of the C8051F340 processor with on-chip universal serial bus (USB) peripherals, three ultrasonic sensors HC-SR04 installed on the top, left, right side of the computer display measuring distance between user and PC, and humidity & temperature sensor DHT11. Through GUI and USB communication, host computer can get user instructions and connect and control the slave computer to finish the functions of calculating the distance between user and PC and collecting the humidity and temperature data. Experimental results show that the presented posture correction device has a humanized GUI and can be used expediently and easily.
