Assessment of Foot Signature Using Wearable Sensors for Clinical Gait Analysis and Real-Time Activity Recognition

Benoît Mariani

Locomotion is one of the most important abilities of humans. Actually, gait locomotion provides mobility, and symbolizes freedom and independence. However, gait can be affected by several pathologies, due to aging, neurodegenerative disease, or trauma. The ...

Pipeline Synthesis and Optimization of FPGA-based Video Processing Applications with CAL

Marco Mattavelli, Ab Al Hadi Bin Ab Rahman, Anatoly Prihozhy

This paper describes a pipeline synthesis and optimization technique that increases data throughput of FPGA-based system using minimum pipeline resources. The technique is applied on \CAL dataflow language, and designed based on relations, matrices and gra ...

Foot worn inertial sensors for gait assessment and rehabilitation based on motorized shoes

Kamiar Aminian, Anisoara Ionescu, Benoît Mariani

Fall prevention in elderly subjects is often based on training and rehabilitation programs that include mostly traditional balance and strength exercises. By applying such conventional interventions to improve gait performance and decrease fall risk, some ...

Merging of range images for inspection or safety applications

Heinz Hügli

Range imagers provide useful information for part inspection, robot control, or human safety applications in industrial environments. However, some applications may require more information than range data from a single viewpoint. Therefore, multiple range ...

Relationships between dual-task related changes in stride velocity and stride time variability in healthy older adults

Kamiar Aminian, Bijan Najafi

Dual-task related gait changes have been previously reported for healthy older adults, suggesting that gait control requires attention. Compared to balance control, the involvement of attention in the control of the rhythmic stepping mechanism, as reflecte ...

Introduction:Gait and posture in PD patients are generally analyzed in laboratory. However, laboratory techniques do not allow estimating long-term ON/OFF fluctuation in PD patients. Here, we propose an ambulatory system based on kinematic sensors that det ...

Stair climbing detection during daily physical activity using a miniature gyroscope

Kamiar Aminian, Anisoara Ionescu, Bijan Najafi, Brian Coley

A new method of monitoring physical activity that is able to detect walking upstairs using a miniature gyroscope attached to the shank is presented. Wavelet transformation, in conjunction with a simple kinematics model, was used to detect toe-off, heel-str ...
