Abstract
While a user performs an activity, a photoplethysmograph (PPG) sensor or other type of sensor is secured to the user's torso. Movement of the user's torso due to breathing changes the distance between the torso and the sensor, affecting an amplitude of a signal determined by the sensor. The amplitude is used to determine the position and rate of movement of the user's torso, which may indicate breath movements of the user. A camera acquires video data representing the user performing the activity. The position of the user's body and the portion of the activity being performed are determined based on the video data. An expected breath movement for the portion of the activity is determined. Corrective instructions or confirmations are output to the user based on the expected breath movement and the user's breath movement that was determined using the sensor.
