30.04.2020. The Technical University of Denmark, as a member of the EU Horizon 2020 ReHyb project, is conducting research into augmented and virtual reality interfaces to exoskeletons for stroke patient recovery through hybrid rehabilitation. This video is focused on the research and experimentation developing the software interfaces and required interaction capabilities using the Unity 3D creation platform and rapid prototyping of an upper-limb exoskeleton out of Lego Technic components and a Lego Mindstorm control unit for data processing. Exploration and understanding of i/o control systems and data flows at a base level will enable the development of more complex multimodal interfaces and control systems which are integrated and control by an artificial intelligence module.
