Base on the preliminary research results, the design goal of this project is defined: Providing departing, arriving and transferring travellers a seamless experience, which makes them feel confident and relaxed during the whole process of their journey in Schiphol, including wayfinding, searching information, learning of the Dutch transport system,
check-in and even passing border control, Etc. This can be achieved by facilitating the Schiphol information providing and wayfinding to help travellers understand the Schiphol service, wayfinding and transportation system and meet all their varying needs. The emphasis of this project is not to improve the Schiphol's service system or add new service in Schiphol, but to help travellers understand and utilize Schiphol's current service system by building a new efficient app information architecture and AR navigation system.

This project explores which information structure is more suitable for Schiphol (Public transport system). Through continuous testing and iteration, the information architecture of the new Schiphol app is confirmed, which would combine with the liner pattern and Hub and spoke information structure to build the underlying information architecture of the app. Choosing the Hub and spoke as the primary parent pattern and applying liner pattern for subsections.

In the user testing phase, it was discovered that functionality, ease of learning, and fun are all essential factors that affect user performance with the new Schiphol app. The focus of the second iteration is to ensure that users can understand and use the app. Make the layout of each interface and visual elements of the app more familiar to all users. The third iteration mainly focuses on the ease of use and fun of the new app. More attractive visual elements and dynamic effects are added to enhance the app's interest. After three rounds of testing, the new Schiphol app can meet the needs of all participants and combines functionality and fun.

Overall, the new app can help travellers quickly obtain the information they need and learn about Schiphol (Schiphol wayfinding system, Schiphol service system, Dutch public transportation system). At present, only about one per cent of passengers will download the Schiphol app in advance, so how to help them realize this app and download it is still an issue that Schiphol needs to consider in the future.
