I sell my “very practical invention”, the VirtualVizor®: “astonishingly good” Virtual Reality glasses for smartphones and “Highlight” of the CeBIT. A disruptive new technology in mobile entertainment with sales rising from 0,8 bn $ (2014) to 4,5 bn $ (2018). Unlike other VR glasses, which are constructed like clunky ski goggles, the VirtualVizor® is much smaller, lighter, more comfortable and cheaper. Infos: www.VirtualVizor.com/usa.
