Sensors, 2013•mdpi.comTwo feet motion is estimated for gait analysis. An inertial sensor is attached on each shoe
and an inertial navigation algorithm is used to estimate the movement of both feet. To correct
inter-shoe position error, a camera is installed on the right shoe and infrared LEDs are
installed on the left shoe. The proposed system gives key gait analysis parameters such as
step length, stride length, foot angle and walking speed. Also it gives three dimensional
trajectories of two feet for gait analysis.
