4 Idea Heart beat measurements -Usually electrical impulse or light sensing Can a heart beat be measured via IMU? -Yes it can! Smartphone app + IMU sensor Problem: Reliably representing the heart beat and BPM in the presence of heavy noise. Talk about how heartbeat is usually measured, then move over to the PROOF-OF-CONCEPT idea with an IMU. Explain (with the strap and phone how it works!) Heini Sahlberg (Project manager), Jere Lappi, Petri Kaitajärvi, Viljar Rúnarsson

5 Implementation Slow movement is filtered out Signal is displayedHeart beats detected via peak detection Talk about how the movement is in the same frequency as the information we want. Talk about the picture and mention how the edge detecter COULD be utilized to detect some heart conditions. Heini Sahlberg (Project manager), Jere Lappi, Petri Kaitajärvi, Viljar Rúnarsson
