• Modal Analysis - driven Gaussian Process for a Gait Parameters Estimation and Individuals' classification from CCTV and smartphone camera footages

Develop a machine learning model trained with gait parameters from CCTV (OpenPose-based), MCC, and IMU sensors, incorporating body measurements, age, and gender. Process video footage to analyze gait and correct parameters to match MCC or IMU measurements, enabling precise gait analysis in indoor and outdoor environments. 

• Development of Foot Diagnosis and Shoe Manufacturing Technology for Disabled

Develop 3D scanning technology for digitizing and analyzing foot morphology. Advance plantar surface stiffness measurement, establish diagnostic indicators, and enhance foot assessment models. Utilize finite element analysis (FEA) to study foot deformation and stress distribution for more accurate health assessments. 

• Development of Pressure Ulcer Prevention Ultra-Low Noise Type Posture Change Care Robot

We develop air-cell mattress technology to reduce pressure on ulcer-prone areas and integrate sensor-vision data processing with deep learning. Our research focuses on predicting pressure ulcer risk through advanced algorithms and optimizing posture adjustments to minimize pressure in vulnerable regions.

• Prediction of Diabetic Ulcer and Stiffness of the Soft Tissue of Foot Using Indentation Device 

Our research studies plantar soft tissue changes influenced by biomechanical and pathological factors, particularly in relation to diabetes and abnormal foot pressure. Using a custom indentation device, we analyze tissue mechanics and pressure distribution to predict diabetic ulceration risk. Currently, we are developing AI models to estimate plantar tissue stiffness from gait characteristics, aiming to differentiate stiffness changes caused by pathology versus epidemiological factors 

• Gait analysis of Proshetic Knee for Transfemoral Amputees 

This research compares three lower limb prostheses with pneumatic, hydraulic, and microprocessor-controlled knees (MPK) by evaluating usability and gait analysis in 16 transfemoral amputees within a living lab. Usability was assessed through a questionnaire covering daily living, mobility, and satisfaction, based on ADL and PEQ. Ongoing research explores the correlation between amputees’ plantar pressure and step length
