B. Augmented Reality POI display mode
The system turned on the camera in the smart mobile
device when a user aimed at the real image and transferred the
real images to the augmented reality ecology module. At the
same time, the GPS and electronic compass gained information
regarding the location of the user by means of the smart mobile
device. In addition, the orientation of the user’s face was
transferred to the ecology database to search for the virtual
objects in the surrounding environment. The birds or plants
were shown on the monitor as is demonstrated in Figure 7.
