A playful journey to healing and self-efficacy

User research – The be-all and end-all of human-centered design

User research is an essential foundation for a successful user experience. In this project, the interaction with the target group was particularly important.

Our main motivation was to find out what excites children and what frustrates them. We wanted to understand what kind of games they prefer and which characters inspire them both visually and in terms of content. Getting to the bottom of these questions gave us a fascinating insight into the life of a child with ICP.

We see great potential for inclusion in gaming. Specifically, ICP children experience happiness, self-efficacy, strength, and social belonging through video games. In particular, therapeutic video games allow them to learn about their strengths rather than being confronted with their weaknesses on a daily basis.

The unusual player type of ICP children

The first step in the development of our game was to determine the so-called player type of children. This led us to a surprising discovery: Most ICP children belong to the "philanthropist" group, which is very unusual for children.

Because they experience above-average levels of caring, they look for ways to be there for others. A game mechanic that focuses on competition, rankings or skill would be counterproductive here, as the children are already overburdened with challenges. Our mission was clear: to create a game that would allow children to express their empathy and willingness to help in a virtual world.

"The philanthropist is a socially minded player type who likes to take responsibility and work for others. Philanthropists like to act for a greater cause that has a higher meaning or a deeper purpose or benefit."

A new empowered role for patients

Based on this insight, we came up with the idea of creating a game about raising and caring for a powerful creature. This approach offers a unique way to give children with ICP a sense of control and self-efficacy. By caring for a virtual creature, children can take responsibility and feel like caring caretakers. They see that their actions have a direct impact on the creature's well-being and gain a sense of control and influence, rewarded by the creature's growing affection and strength.

The technology behind MightyU

Naturally, the game was designed to complement the children’s therapeutic exercises. To play the game, the children do not use a conventional controller, but the device they already know from their therapy: a professional medical sensor that measures the patient’s muscle contractions. For the game, we converted this sensor into a game controller.

• The sensor sends a Bluetooth signal to an Arduino microcontroller with a Bluetooth LE module.
• The Arduino converts the signal into commands to control a gamepad.
• The microcontroller can simply be connected to the console via USB-C cable using an adapter.
• The console interprets the setup as a conventional gamepad. The game uses the input as the X-axis value of the left stick.
