AI systems are revolutionizing the way we absorb information and process knowledge. Examples include voice assistants such as Siri and Alexa, learning platforms such as Duolingo, a wide range of commercial AI chatbots, and, in a university context, RWTHgpt and Ritchy at RWTH Aachen University. These technologies use machine learning to provide personalized learning experiences tailored to the needs of individual users.

In this series, the IT Center’s UX team reports on its work. When developing interactive systems such as websites and apps, not only HTML, CSS and JavaScript play a decisive role, but also usability and user experience.
