There has been a lot of talk about Virtual Reality (VR), but still there are very little applications to enhance our everyday lives outside of entertainment. Augmented Reality (AR), the less known sibling of VR, has the power to have a more profound impact on our lives than VR ever could. Instead of replacing the real world with a virtual one, AR enhances the reality with virtual content. Therefore, AR can be a gateway for people in accessing and understanding todays technology and could provide vast possibilities to support our everyday lives, e.g., for navigation, traveling, or education. This talk will give an overview on AR in general and explain its possible benefits and use cases, as well as the issues that may arise, e.g., regarding privacy, data security, as well as psychological and sociological challenges. The talk requires no special knowledge and is suited for people with little exposure to AR and mixed reality, but it will also give insights into current relevant research and development.
