Implementation of Sitting Posture Monitoring System with Kinect

Most modern office workers are seated on the chair for working with the computer during most working time. Generally, the correct sitting posture is critical for human life because wrong sitting posture can lead the back or neck disorder related sickness. The majority of previous researches have been utilized various sensors with special chairs to measure the sitting posture. However, these special chairs can be uncomfortable for users due to unfamiliar sitting environment. Therefore, we proposed the sitting posture monitoring system using Kinect which provides IR depth camera to record user’s sitting posture data and alert wrong posture to user. The proposed system provided 62% increased correct sitting posture during 35 min for 5 participants. We believe that the proposed system can help to improve the behavior of sitting posture of user without any uncomfortable adhesive sensors.
