To make AanZet more appealing to the youth.


Bibliotheek AanZet


I helped to develop an application that gives users an interactive library experience.

I started this project by gathering as much information as possible. I did this via desk research, spreading a survey, interviews with the target group and observations at AanZet locations.

During the research a couple of things stood out. Namely, that the target group like to gather information with as little effort as possible and is marked with instant gratification. Besides that, the target group uses the library mainly to study and doesn’t feel really connected to a specific ‘library brand’.

Based on the identified issues, I narrowed the target group to 20 – 25 year old students. Due to the fact that the target group uses the library mainly for studying, that became the main focus of the project.

I tracked the current library experience by spreading a cultural probe, which led to multiple conformations. This helped shape the three concepts that were presented:

  1. Application with currency system, rewards based on engagement and participation.
  2. Application that enables dedicated study spaces that you can book via reservations.
  3. Application with educational purposes, which can be used in physical spaces within the library.

Iteration 1

The concept that has been elaborated is concept 1. The stakeholders found it the most appealing based on our insights, and a good way to bound the target group to the brand.

During iteration 1 a low-fidelity prototype was developed, to give participants an impression of what the concept would look like. I made a design system and an a/b test for the homepage. This, to validate which components were most desirable. The first prototype was based on a gray-scale, so that the focus laid entirely on the functionality.

Iteration 2

After testing the low-fidelity prototype, more steps were taken to turn it into a high-fidelity prototype. I’ve updated the design system and worked on a more detailed prototype.

Iteration 2 came to live, now with the use of color and more in depth options. The currency now has a name and you can earn ‘biebs’ by engaging in different challenges. Those ‘biebs’ can be spend in the shop on food, drinks, discounts and merchandise.

The last week was dedicated to minor fixes, such as bugs, flow improvement, a more balanced currency, little additions such as the option to view friend profiles and a product tour.

The product is consistent with the target group and client (AanZet), the integration of the color scheme could’ve been more delicate. Other than that the functionality was pretty much flawless. The target group found it more engaging to study if they’d gain credit for it. Especially since a large part of the group is used to take a coffee or break in the library, the application would give them more reason to study longer and/or visit more often.
