The object of the VRExpo (https://vrexpo.gr/) project is the development of a platform for the easy and without special technical knowledge creation of virtual-interactive kiosks and exhibition spaces, as well as the navigation in these spaces through computer, tablet, mobile and VR glasses. With this platform, trade fairs, which for any reason can not be held in real places and with a physical presence of the public and exhibitors, as is the case with the coronavirus pandemic, will be able to be hosted and conducted in a virtual environment for the purpose of the marketing of products and services and the realization of trade agreements. The project is carried out in collaboration with two agencies: a) the company TETRAGON SA, which in recent decades has starred in the design and implementation of exhibitions, exhibition spaces and events for public and private agencies, organizations and companies both in Greece and abroad, and b) the Institute of Information and Communication Technologies of the National Center for Research and Technological Development (CERTH), which in the framework of various European research programs develops, among many others, software and tools for the synthesis of three-dimensional experiences.
