METHOD AND APPARATUS FOR DETECTING SMOKING BEHAVIOR BASED ON ACCELERATION SENSOR

摘要

Disclosed is a method of detecting a smoking behavior based on an acceleration sensor. A method of detecting a smoking behavior based on an acceleration sensor according to an exemplary embodiment of the present disclosure includes: calculating a wrist acceleration variation value which is a variation value of gravitational acceleration applied based on a gravitational direction with respect to a user's wrist in accordance with a motion of the user's wrist by using a three-axis acceleration sensor worn on the user's wrist; converting the wrist acceleration variation value into a wrist angle variation value which is a variation value of a wrist angle that indicates an angle to the user's wrist based on the gravitational direction; comparing at least one template signal made by modeling the variation value of the user's wrist angle corresponding to a smoking behavior with the wrist angle variation value; and detecting the user's smoking behavior based on the comparison result.
