Grip sensing method and apparatus
Disclosed herein are grip sensing method and apparatus. The grip sensing method includes generating a sensing count by differentially amplifying a voltage potential of a grip channel based on a predetermined correction offset and performing digital conversion, comparing the sensing count with a predetermined base value to determine whether a touch condition is satisfied, performing baseline tracking for determining a baseline count based on the sensing count when the sensing count is less than the base value and the touch condition is not satisfied, stopping the baseline tracking and performing temperature compensation with respect to the baseline count using a temperature sensor mounted therein when the sensing count is equal to or greater than the base value and the touch condition is satisfied, and sensing an event based on the sensing count and the temperature-compensated baseline count.
