Abstract :
Aiming at car driver´s motion estimation, foot motion estimation while no pedal operations has been investigated. We use a sensor utilizing Doppler effect in a microwave to detect motion of foot. Sinusoidal wave obtained from the sensor, we estimate time-varying frequency and amplitude of the wave by state space modeling approach with particle filter for state estimation. Furthermore, we devised a novel model for estimating position and velocity of the foot by incorporating pedal signal. Several experiments with Linear sliding machine for obtaining fundamental property and foot pedal have been reported.
