This system assesses the balance between energy consumption and heart rate tracking error. Depending on the connection status, a user-specified error, energy constraints and an estimate of the input difficulty, CHRIS employs two heart rate prediction algorithms. These are executed on either the smartwatch or the phone.<\/p>\n\n\n\n<p>CHRIS showed the potential to achieve up to 2.03 times energy reduction on the smartwatch by deferring processing off the smartwatch, without a reduction on the tracking accuracy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>There&#8217;s often a dilemma when creating Bluetooth systems whether to place the processing on the smartphone or on the Bluetooth device.
