Augmented Reality (AR) is a powerful tool used to revolutionize the services sector, including healthcare, education, marketing, manufacturing, and others. Its use cases make it an amazing possibility for developing new skills in the IT industry and gaining practical knowledge. The ability to display digital information through varied devices, including smartphones, tablets, PC, Head-Mounted Displays (HMDs), etc., makes it an impressive possibility for surgeries, detecting both physical and mental disabilities, displaying human anatomy, improving the accessibility of people in need, and learning new languages. Being the current leader of HMDs, Microsoft HoloLens is a device of major importance for Augmented Reality.
