Figure 1.

Left: Our approach estimates the breathing signal and rate of a user, using body posture data and the raw depth signals from a depth camera in the environment. The user is assumed to be indoors and facing the camera, for instance while performing activities guided by a display, but can be anywhere in the frame, upright or sitting, and she can perform activities that self-occlude the torso. Right: An example application with the user performing a relaxation exercise with guided respiration while her breathing is tracked and evaluated over time.
