The hub consists of three parts, these are: the nodes, the case, and the tablet. The nodes are the separate parts that can be mechanically clicked onto any gym equipment, they contain sensors and colored LEDs with which the user can interact. The case is the part in which the nodes can be charged, it also contains a router that provides wireless communication. To select exercises or games, a tablet is required with an associated application, which is wirelessly connected to the case and the nodes. The activated lamps should be switched off themselves as soon as possible. Speed, program duration and light and sound settings can be easily adjusted on the accompanying tablet. The loose Clips can be placed on floors, walls and objects. The Clips can be attached to almost any surface thanks to a combination of magnets and Velcro.
