Summary

In medicine, augmented reality (AR) technology can offer added value over traditional education, assessment and interventional approaches. By combining our expertise in motion capture, 3D anatomical modelling and AR technology, new solutions can be proposed to improve medical treatment.

In this project, we developed an anatomical see-through tool to visualize and analyze patient’s anatomy in real time and in motion for applications in sports medicine and rehabilitation. This tool allows healthcare professionals to visualize joint kinematics, where the bones are accurately rendered as a holographic overlay on the subject (like an X-ray vision) and in real-time as the subject performs the movement.

Summary

The goal of this project was to simulate reverse shoulder prostheses (RSA) to evaluate the variability of several biomechanical factors and the impact on the range of motion. In particular, we were interested in evaluating the effect of glenoid lateralization, humeral inclination and critical shoulder angle (CSA). These computer-assisted simulations provided operating parameters which aimed to minimize the onset of articular conflicts and luxations.

In this project, Artanim was responsible for dynamically simulating reverse shoulder prostheses from kinematic data.

Summary

A sample model on a higher technological level, such as a precise virtual 3D prototype, contains innovative numerical fitting information (e.g., data about the areas of compression of a garment) that could improve the design and quality of the final sports garment and better satisfy the customer.

The aim of this research project was thus to reform existing garment prototyping processes for the active sportswear sector. The main focus was on the definition of accurate physical and mechanical high-tech sports fabric properties and on the use of virtual sports body animations to perform accurate simulation of sports garments.

In this project, Artanim was in charge of providing realistic body animations of different sports (alpine skiing, Nordic skiing, running and hiking). Moreover, Artanim worked on the development of software tools to improve the fabric measurements protocol by analyzing body motion and deformation.

Summary

Social interaction generally involves a multi-layered interaction where there is an interplay of self and other representations together with a participatory factor where people feel “they do things together”. Descriptions of this interaction range from high-level intentional descriptions on shared representations down to precise motor, gestural and postural studies on behavioral coordination.

In this project, we used motion capture in order to record and study specific motor factors of two people when they engage in joint action tasks and/or in social interaction. It was hence possible to obtain quantitative measurements at the behavioral level (body posture, motor coordination and synchronization, nonverbal language, etc.) in order to explore the brain and bodily mechanisms that relate to it. Respiration coupling and dual electroencephalography were also performed in this project.

Summary

The goal of this project was to develop several surgical planning tools taking into account both the anatomy and kinematics of the patient’s joint. We intended to continue and extended our previous research works by integrating them into a 3D surgical planning solution, called ArthroPlanner, which could be used in clinical routine and could thus directly benefit patients.

This project mainly aimed at developing solutions for the dynamic planning of the hip and shoulder and at extending our work to the knee.
