Mixed Reality Geographical Information System


Mixed Reality Geographical Information System (MRGIS) is the evolution of the Augmented Reality Geographical Information System (ARGIS) that started in City University in January 2005 with the aim of presenting geographical information in a new and educational way. MRGIS is a tangible mixed reality interface designed for windows-based operating systems that allows users to superimpose three-dimensional geographical information into the real environment and interact with it in a user-friendly manner. MRGIS provides an effective combination of VR and AR visualisation into a single interface.




MRGIS provides the necessary technology to visualise 3D geographical information in real-time performance using any type of commercial computer (desktop, laptop or tabloid). Currently, the multimedia augmentation of virtual information consists of 3D buildings, 3D maps, spatial sound, 2D maps and textual information. Users can perceive a multimedia augmentation either on monitor-based displays (i.e. CRT, LCD, or TouchScreen) or on head mounted displays (HMDs). Users can interact in a number of different ways including tangible, hardware and software based solutions. Tangible interactions are performed using natural marker cards. Hardware interactions are realised through the use of I/O devices such as the keyboard and the mouse or even more sophisticated devices like magnetic sensors and GPS. Software based interactions are performed using the functionality implemented in the user-friendly graphical user interface (GUI).




MRGIS can be used as a pilot to generate innovative AR applications focused on geography and not only. Two applications have been designed: one for navigation into urban environments and one for educational purposes. AR puzzle is the first educational application that have been experimentally designed and some initial results are presented. Below you can find some of the events where MRGIS was disseminated.
