Fig. 5From: Foot progression angle estimation using a single foot-worn inertial sensorAcceleration profiles of representative subject. The acceleration (\(A^X_t\)) profiles (shown in solid lines) before transforming them to the dynamic foot frame as shown in Fig. 4 are compared to the accelerations (\(A^{F_i}_t\)) when this transformation has been applied (shown in dashed lines)Back to article page
