We present a user study to investigate the impact of explanations on non-experts'
understanding of reinforcement learning (RL) agents. We investigate both a common RL …

Despite the importance of attention in user performance, current methods for attention
classification do not allow to discriminate between different attention types. We propose a …

In remote collaboration, gaze visualizations are designed to display where collaborators are
