Abstract: Disclosed is a gait start intention detection device for detecting a walker's gait start intention, including a plurality of left foot sole sensor units and a plurality of right foot sole sensor units to measure ground reaction force signals generated from foot soles while walking, and a calculation unit to receive and calculate the left ground reaction force signal and the right ground reaction force signal, wherein the calculation unit calculates a center of pressure (COP) location in a walking direction and a direction perpendicular to the walking direction using data of the ground reaction force signal measured from each sensor unit, and detects the walkers gait start intention when a ground reaction force of a swing foot heel of the walker increases, and at the same time, the COP location moves to a rear side of the walker.
