Intended use

movement and physiological parameters. These
metrics are intended as input for behavioral change
programs for managing lifestyle of individuals with
risk of or aected by weight and activity related
chronic disease. The device is intended for 24/7 use
in daily life, both indoor and outdoor, by adults of

Operating principle
The Philips health watch is a wrist-worn device for
24/7 home use (indoor and outdoor). The device
uses a tri-axial accelerometer to measure motion
and green Light-Emitting Diodes (LEDs) and a
photodiode to create a photoplethysmogram (PPG).
The accelerometer output and the PPG-signal are
analyzed to determine heartbeat, activity type,
steps taken, and are used as input for estimation
of energy expenditure and other parameters.
