Moregrasp: Restoration of Upper Limb Function in Individuals with High Spinal Cord Injury by Multimodal Neuroprostheses for Interaction in Daily Activities

The aim of the MoreGrasp project is to develop a noninvasive, multimodal user interface including a brain-computer interface (BCI) for intuitive control of a grasp neuroprosthesis to support individuals with high spinal cord injury (SCI) in everyday activities. We describe the current state of the project, including the EEG system, preliminary results of natural movements decoding in people with SCI, the new electrode concept for the grasp neuroprosthesis, the shared control architecture behind the system and the implementation of a user-centered design

Technical Concept and Technology Choices for Implementing a Tangible Version of the Sokoban Game

This paper presents and discusses the technical concept of a virtual reality version of the Sokoban game with a tangible interface. The underlying rationale is to provide spinal-cord injury patients who are learning to use a neuroprosthesis to restore their capability of grasping with a game environment for training. We describe as relevant elements to be considered in such a gaming concept: input, output, virtual objects, physical objects, activity tracking and personalised level recommender. Finally, we also describe our experiences with instantiating the overall concept with hand-held mobile phones, smart glasses and a head mounted cardboard setup
