ArcadeRadar · Arcade Game Preview App

Have you ever paid for a game that you ended up not enjoying at all? No matter if you play on your mobile phone, your desktop or old-school in an arcade, if you play alone or with others, having some information about the game in advance or even having tested it before playing can make the experience much more enjoyable.

The problem

People who love to play Arcade games can have a hard time figuring out what games are available, what the games are about and if they would enjoy playing them. Occasional gamers might find certain games too advanced while avid gamers might have trouble finding people to compete with at their level.

The goal

The primary goal was to design an app that allows users to easily preview and test Arcade games before committing to paying for them and not enjoying the games. The app also offers a way to connect with like-minded people in the community to talk about gaming, arrange meet-ups, or even find a mentor to advance their skills.

Understanding the user

User research and personas

To empathise with the users and to understand their needs, desires, motivations and frustrations, I conducted interviews and built personas. Through research I identified game enthusiasts who don’t have an option to preview games without spending a lot of time and money as primary user group. This confirmed initial assumptions about ArcadeRadar’s customers. Research also revealed that other user groups include occasional users who are less advanced and users with disabilities.

Ideation and design

By sketching story boards I tried to visualise the user’s experience and explore possible user flows. Informed by user research, paper wireframes and story boards I started to create early screen designs for the app. Accessibility was one of the pain points that needed to be addressed in the design. Additionally, there needed to be options for ‘newbie’ gamers to find help and guidance.

The test screen offers several options to take action by testing, sharing, saving etc.
The menu gives quick and easy access to support, community, settings and more.

Usability testing

I used feedback from usability testing to see if pain points were adequately addressed, if there are any additional frustrations and what aspects of the design still needed refinement.

Refining the design

Early designs allowed the user to click on an image to select a game. After usability testing I added additional buttons to give users more options and make the app easier to use. I also revised the layout of the listed games and filter option to make it more accessible for people with disabilities.

USA.Gov · Digital Passport App



UI, User Research, Information Architecture, Personas, Wireframes


In today’s highly technological and digital world everything runs at a fast pace.
You read fast, you walk fast, you order fast, you eat fast. But then, why don’t you travel fast?
Long lines at airports are a familiar and disliked phenomenon to almost every traveller.
Digital boarding passes and self-service terminals have become very common at most
airports but still, air travel is far from being a fast and efficient experience.


The digital passport app is best understood as an extension of the services of
the US government’s web presence. The app is designed to make air travel faster and more
convenient. By utilizing digital technology, such as biometric data or a digital version of
the passport, it aims at speeding up processes like customs control or simply boarding
a plane. The traveler can access documents and travel history in one secure place.

the app provides

o digitized documents like passport, visa etc.

o higher security factor with fingerprint access only

o detailed travel history

o permanent resident status, tracking, renewal

o interactive translator, interpreter

o easy way finding to customs/border control etc.

Creating low-fidelity wireframes helped to visualize usability insights and a rough concept. Due to the amount of data that needed to be included in the app, a well structured and organized application was needed to enable a seamless and pleasant user experience.

the passport

Store all your biometric data in the app, login with your unique fingerprint, and have your passport available for scanning and identification wherever you need it in just two clicks.

travel documents and history

Access all documents you need for your journey as well as your travel history in one application. Find the hotels you stayed at, the flight numbers of flights you travelled on or what documents you used to enter a country you visited.
