First Prototype - link
The original!

• Basic layers
• Two information panes (Universität, Heusallee)

Second Prototype - link
This prototype was developed shortly after the first one. We included some functionality that didn't make it in the original software prototype.

• Navigation buttons

Third Prototype - link
An external action pane was added for this prototype. The objective of this prototype is to simulate actions that can be done with the cell phone.

• Connection information was added. Take a picture with your phone!
• When selecting a layer the background map changes to highlight the new layer

Fourth Prototype - link
Refinements! Along with some minor changes, we introduced a typing demo for filtering the list.

• Connection label made bigger
• Bigger direction buttons
• Transparency for direction buttons in map
• New information pane for Münster Platz (sightseeings)
• Labels in information panes changed to avoid confusions
• HandyTicket code added to information panes

Fifth Prototype - link
Final prototype! Done after user comments and heuristic evaluation

• Zoom in/out and zoom indicator were added but no functionality was implemented
• Labels for layers (bus, trains, sightseeing) were changed to avoid further confusion
• Transparency for the left pane
• Help system. Sorry, in latin
• Buttons for sliding the list were added although the implementation wasn't done
