There are three ways to access information in the application:
1. Clicking on a point-of-interest
2. Clicking on a photo in the list of available photos
3. Looking on the map
All three methods can be combined with filtering to look at photos from a specific decade. We will below present the main functionality of the system
• Augmented Reality View: The augmented reality view is the
main view of the application where points of interest (POIs)
are shown as floating icons overlaying the camera feed. The
name of the application is shown in the toolbar at the top. The
view is shown in figure 2.
• Photo Overlay: Figure 3 shows one of the application’s transparent photo overlays. These let the user see historical images
over the present day scene. The buttons in the toolbar at the
top of the screen are used to close the overlay or go to the
detailed information view belonging to the picture.
• Detailed Information View: Each of the photographs in the
application has an associated detailed information view. One
of these is shown in figure 4. It contains a description of the
motive and let the user know when the picture was taken, the
source of the photograph and the name of the photographer.
• Timeline: The timeline is always visible at the bottom of the
screen. It lets the user filter the amount of incoming information so they only see photographs from a specific decade. The
selected decade is marked in green and written in the upperleft corner
• Map: Figure 5 contains a screen shot of the application’s map.
It shows the user’s current position and the position of photos
from the decade selected on the timeline. Each pin is tagged
with the name of the photo and the distance from the user. It is
not possible to open photographs from the map in this version
of the application.
• List View: Figure 6 shows the application’s list view. This
view shows the user a list of all photographs from the selected
decade and provides a convenient method to open detailed
views without having to locate the associated markers
