Abstract
Disclosed are a method and an apparatus for calculating a meal period, the method including: calculating, by a wrist acceleration calculating unit, a wrist acceleration variation value which is a variation value of acceleration in respect to a motion of a user's wrist which is measured based on gravitational acceleration; calculating, by a wrist angle calculating unit, a wrist angle variation value which is a variation value of an angle to the user's wrist based on a gravitational direction by using the wrist acceleration variation value; detecting, by an eating behavior candidate pattern detecting unit, an eating behavior candidate pattern based on a predetermined reference by applying one or more threshold values to the wrist angle variation value; and calculating, by a meal period calculating unit, a meal period based on the number of times the eating behavior candidate pattern occurs.
