In this poster, we are addressing the topic of “system’s evaluation” from the point of view of assessing the usability of a gamified experience with 20 teenagers aged 15–17 years. The currently tested experience was ideally designed for children 9–10 years. In order to adapt the application to teenagers, we tested it with 20 targeted users. In this poster, we share the results and encourage a discussion among the researchers about how to adapt the gamified experience designed for children to a teenage audience.
