Abstract: An interactive physiological monitoring device includes at least one physiological sensor including an oximetry sensor, at least one motion sensor; and control electronics. The control electronics receive data from the physiological sensor and the motion sensor. The control electronics enter a lower power mode in the absence of a detection of motion from data from the motion sensor over a time interval. The interactive physiological monitoring device further includes a display device, wherein the control electronics cause a representation of data from the physiological sensor to be output to the display device.
