The application of deep learning can lead to increased prediction performance in a wide variety of use cases. However, in high stakes decision contexts like for example medicine, an increase in performance on its own can be insufficient to foster trust towards a predictive model. If lack of trust has the effect of the high performance decision support system around the deep learning model not being used, nothing is gained. Developing an interface with the intention of convincing users of its plausibility on the other hand risks overtrust and an abandonment of critical thinking, especially among less experienced professionals. XAI methods are a way to support appropriate levels of trust by giving users tools to detect faulty reasoning by an otherwise inscrutable deep learning model. We have developed visualizations as explanations of treatment effect predictions. During our evaluation of these visualizations, several experts voiced their interest in interactive components to explore the model's reasoning and underlying data to develop a better understanding. 

To build on our visualizations a structured literature review on interactivity in decision support systems is conducted in this Bachelor's thesis. On the basis of this SLR the student develops an interactive explanation interface for a medical treatment effect prediction case and evaluates it in a series of expert interviews.

Notifications from instant messaging applications can interrupt employees' productive time. While there are different ways to influence the notification behavior of instant messengers, such as turning off the application or muting notifications for certain periods of time, these measures require self-discipline and/or often result in missing notifications when not in flow. We have developed an adaptive instant messaging blocker that aims to solve this problem by recognizing the user's flow state at predefined intervals, based on their physiological data and using machine learning methods. As soon as a flow state is recognized, the “do not disturb” status is automatically activated for the duration of the flow state.

We conducted interviews with knowledge workers to evaluate the developed system. Therefore, a qualitative analysis (with MAXQDA) is to be carried out in this Master's thesis in order to evaluate the system on the basis of the interviews conducted.
