“…A hybrid setup that combines desktop and immersive environments as it is being investigated for other application domains [WBR*20] may also be possible. Evaluation between modalities (e. g., VR vs. desktop) may not always be feasible due to the novelty of immersive devices or the lack of a comparable desktop tool, but some generic comparisons of specific aspects such as input and output devices [WBAI22] are possible. Evaluation within a modality through a quantifiable measurement of task completion time, however, could advance the field of molecular visualization in immersive environments.…”

Visualization plays a crucial role in molecular and structural biology. It has been successfully applied to a variety of tasks, including structural analysis and interactive drug design. While some of the challenges in this area can be overcome with more advanced visualization and interaction techniques, others are challenging primarily due to the limitations of the hardware devices used to interact with the visualized content. Consequently, visualization researchers are increasingly trying to take advantage of new technologies to facilitate the work of domain scientists. Some typical problems associated with classic 2D interfaces, such as regular desktop computers, are a lack of natural spatial understanding and interaction, and a limited field of view. These problems could be solved by immersive virtual environments and corresponding hardware, such as virtual reality head‐mounted displays. Thus, researchers are investigating the potential of immersive virtual environments in the field of molecular visualization. There is already a body of work ranging from educational approaches to protein visualization to applications for collaborative drug design. This review focuses on molecular visualization in immersive virtual environments as a whole, aiming to cover this area comprehensively. We divide the existing papers into different groups based on their application areas, and types of tasks performed. Furthermore, we also include a list of available software tools. We conclude the report with a discussion of potential future research on molecular visualization in immersive environments.

“…As completion-time data presents with a positive skewness and is thus not normally distributed, we analysed log-transformed measurements and present anti-logged results, which is a standard analysis [11,75] that is commonly used in HCI and visualisation work (e. g., [13,44,89]). We consequently present, for completion time measurements, geometric means which dampens the effect of potential extreme completion times that would otherwise bias arithmetic means.…”

Focus-and-context techniques allow visualisation users to keep a full dataset in view while making detailed selections. Such techniques have been studied extensively on desktop to allow precise selection within large data sets, but they have not been explored in immersive 3D modalities. In this paper we develop a novel immersive focus-and-context technique based on a "magic portal" metaphor for precise data-point selection within larger-than-room-scale 3D scatter plots. We compare linear and non-linear gain "Go-Go arm" implementations reaching to place the portal, finding that non-linear gain may help people who have difficulty judging depth at a distance. We find strong evidence that portals reduce overshoots in selection and overall hand trajectory length. The portals also enable us to use a robot arm to provide haptic feedback within the limited volume of the portal region. We demonstrate applications for portal-based selection through two use-case scenarios.

“…Pushing the concept further, some researchers proposed to use mobile devices which, combined with their tactile screens, provide more versatility for data exploration or selection through a combination of touch and tangible interaction [7,11,47,60,62]. Other approaches have also relied on commercial devices such as the 3D mouse [73].…”

“…9. To correct for the positive skewness of completiontime data, we analysed log-transformed measurements and present anti-logged results, which is, considering the log-normal distribution of time data, a standard analysis [5,57] that is commonly used in HCI and visualisation work (e. g., [8,38,73]). We consequently present geometric means which dampens the effect of potential extreme completion times that are likely to bias arithmetic means.…”
