CPR saves lives. According to the American Heart Association, “100,000 to 200,000 lives of adults and children could be saved each year if CPR were performed early enough [1]"  While CPR is undoubtedly a valuable skill to have, many people might not feel confident in performing CPR in an actual emergency, even if they were trained. 

 

CPRactice is a proof-of-concept that CPR practice can be done anytime anywhere with basic equipment like a phone. By performing Fourier Transform on user’s compression motion data collected with smartphone built-in sensors and Phyphox, our algorithm evaluates the CPR performance and gives feedback based on the consistency, pace, and force applied.
