Chloe@University: An indoor, HMD-based mobile mixed reality guide

This paper describes an indoors, mobile mixed reality guide system: Chloe@University. With a see-through head-mounted display (HMD) connected to a hidden small computing device, Chloe@University provides users with an efficient way of guiding in a building. Augmented 3D virtual character in front of a user guides him/her to destination so that he/she can just follow the virtual guide after the user gives a voice command with desired destination to it. The most suitable virtual character is selected depending on a user’s preference for personalized service. For adapting to different indoor environments, the proposed system integrates various localization approaches. In addition, it supports different access right to a building map based on user profiles and security level.
