23. A wearable health monitoring device, comprising:
-
a sensor for generating movement data indicating movement of a user; and logic configured to calculate activity-induced energy expenditure (AEE), a relative minimum and a relative maximum, and to determine whether the user is vertical, based upon the movement data, the logic further configured to determine based upon the AEE, the relative minimum, the relative maximum, and the vertical determination whether the user has taken a step. - View Dependent Claims (24)

25. A health monitoring method, comprising:
-
generating motion data indicating movement of a user; calculating activity-induced energy expenditure (AEE) based upon the motion data; calculating a relative minimum based upon the motion data; calculating a relative maximum based upon the motion data; determining whether the user is vertical based upon the motion data; and determining based upon the calculated AEE, the relative minimum, the relative maximum, and the vertical determination whether the user has taken a step. - View Dependent Claims (26, 27)
