Metaverse is the buzzword of the day, but what it is, what it can be and how to make or participate in something like that are topics that are still between black magic and black box. In this lecture, Ivan will talk about the path his startup Equinox Vision has chosen in building metaverses through augmented reality technologies, with an emphasis on the many, often very entertaining problems they have encountered, or because of which they have possessed. The lecture will have a technical and business component, and most of the technical details will be about the Unity development tool.
