Using RGB-D Sensors to Assess Sitting Balance

Subject performs seated balance exercises in front of an RGB-D sensor. System tracks joints and calculates body angles. System generates graphical outputs of body movements.

Research project supervised by Dr. Jorge Dorribo Camba

My role: design & development of software application

Having good sitting balance is crucial to be able to carry out daily tasks, but common balance assessment tools aren’t accessible for people who can’t stand. I used a programming tool called Processing to build a software system that uses the Microsoft Kinect to track a person’s movements while in a seated position. Occupational therapists can use the data generated by this system to more accurately assess the sitting balance of their clients.

Screenshots of the software system

Screenshot shows setup on the left and person sitting in front of the camera on the right.
Software shows person sitting with an overlay of the tracked joints shown with green dots and lines. A start test button can be pressed.
Final screen shows two graphs, one is a bird's eye view of the person's body position and the other is the changes in position in X, Y, and Z directions.
