HoloStudy Biology is a joint project of HoloGroup and Nanobot Medical Animation Studio, and is part of HoloStudy - a series of educational lessons. Application is devoted to the structure and properties of the cell of living organisms. High level of competence in the development of applications for Hololens, as well as design and digital graphics on medical topics, allowed to create an unusually colorful and informative application. User has the opportunity to study in detail the structure and functions of each cell organ (nucleus, mitochondria, DNA, etc.). The application has two modes: interactive, where the user can independently navigate from section to section, receiving information through info-windows, and a lesson mode in which, accompanied by a virtual professor's lecture, you will make an exciting journey through the cell. HoloStudy Biology is a colorful and exciting application that is suitable for both children and adults. Do not miss the opportunity to get new or refresh old knowledge.
