Summary

VR+4CAD aims to tackle issues limiting the use of VR in manufacture and design as highlighted by the industries: the lack of full circle interoperability between VR and CAD, the friction experienced when entering a VR world and the limited feedback provided about the experience for future analysis.

In this project, we target CAD-authored design to be automatically converted and adapted for (virtual) human interaction within a virtual environment. Interaction is made more immediate by means of an experimental, markerless motion capture system that relieves the user from wearing specific devices. The data acquired by motion capture during each experience is analyzed via activity recognition techniques and transformed into implicit feedback. Both explicit and implicit feedback are merged and sent back to the CAD operator for the next design iteration.

Summary

VR-Together offers new ground-breaking virtual reality (VR) experiences based on social photorealistic immersive content. For this purpose, this project developed and assembled an end-to-end pipeline integrating state-of-the-art technologies and off-the-shelf components. The challenge of VR-Together was to create photorealistic truly social VR experiences in a cost effective manner. Immersive media production and delivery through innovative capture, encoding, delivery and rendering technologies. The project demonstrated the scalability of its approach for production and delivery of immersive content across 3 pilots. It introduced new methods for social VR evaluation and quantitative platform benchmarking for both live and interactive content production, thus providing production and delivery solutions with significant commercial value.

In this project, Artanim worked on content production for the 3 pilots combining VR and offline/real time motion capture and developed new tools for immersive media production. We also participated in the evaluation of the developed social VR experiences.

Summary

Immobilization and prolonged bed rest are causing deleterious consequences at the musculoskeletal, pulmonary, cardiac, endocrine and metabolic levels. Physical exercise is an effective way to maintain muscle strength and limit these adverse effects.

The University Hospitals of Geneva developed a “Cyclo” rehabilitation device that adapts to the patient’s physical abilities, irrespective of the nature of his/her pathology (neurological, orthopedic, etc.) and his/her conditions of hospitalization (bed, chair, wheelchair). Several scenarios are proposed according to the type of movement (circular, linear).

In this project, Artanim integrated a virtual reality (VR) module to the device in order to get patients moving actively or passively into an immersive VR world that would make them forget during the time of care the clinical context (or even forget the pain). For example, a patient could go pedaling on a river (as in the video above) or take a bike ride in the countryside by pedaling at his/her own speed from an hospital bed. The goal iss also to gamify the rehabilitation session in order to motivate patients to do physical exercises.
