Doing computer work with an incorrect posture can lead to headaches, neck pains and more. In this project, we propose a system that assists the user to sit at the computer correctly. To do so, we developed a real-time system that analyzes the sitting position of the user and alerts when it might be harmful. The system classifies the user's posture and informs the user how to correct it, if necessary. For this analysis, the system uses Microsoft Kinect-2TM sensor’s body tracking capabilities, which provides data such as location and orientation of joints like head and shoulders. Using this data, the system can identify a wide variety of features consistent with wrong posture such as wrong head neck angle.
The system was tested on a group of 6 participants showing good identification abilities along with no false alarms.
