Besides the ability to utilize visualizations, the process of creating and authoring them is of equal importance. However, for visualization environments beyond the desktop, like multi-display or immersive analytics environments, this process is often decoupled from the place where the visualization is actually used. This separation makes it hard for authors, developers, or users of such systems to understand, what consequences different choices they made will have for the created visualizations. We present an extended visualization authoring model for Post-WIMP interfaces, which support designers by a more seamless approach of developing and utilizing visualizations. With it, our emphasis is on the iterative nature of creating and configuring visualizations, the existence of multiple views in the same system, and requirements for the data analysis process.

The research field of augmented reality (AR) is of increasing popularity, as seen, among others, in several recently published surveys. To produce further advancements in AR, it is not only necessary to create new systems or applications, but also to evaluate them. One important aspect in regards to the evaluation is the general understanding of how users experience a given AR application, which can also be seen by the increased number of papers focusing on this topic that were published in the last years. With the steadily growing understanding and development of AR in general, it is only a matter of time until AR devices make the leap into the consumer market where such an in-depth user understanding is even more essential. Thus, a better understanding of factors that could influence the design and results of user experience studies can help us to make them more robust and dependable in the future. In this position paper, we describe three challenges which researchers face while designing and conducting AR users studies. We encountered these challenges in our past and current research, including papers that focus on perceptual studies of visualizations, interaction studies, and studies exploring the use of AR applications and their design spaces.
