III. RESEARCH METHODS
This research used augmented reality technology to design
and build an ecological navigation system for a campus
providing some excellent interface functions for accessing
ecological information. This system makes everything more
vivid when are working on ecology for a campus environment
tour. It focused on interaction between user and system. In
addition, the Location-based Services mechanisms were
involved. This study developed a friendly user interface
integrated with interactive multimedia-rich smart mobile
devices, touch screens equipped with global positioning
systems, and an electronic compass to integrate ecological
environment navigation, by creating an interact
