As result, refined model, embedding HCI into relation Based on this,...

Recent research in the area of immersive analytics demonstrated utility head-mounted augmented reality devices for visual data analysis. However, it can be challenging to use by default supported mid-air gestures interact with visualizations (e.g. due limited precision). Touch-based interaction via mobile devices) compensate these drawbacks, but is two-dimensional input. In this work we present STREAM: Spatially-aware Tablets combined Augmented Reality Head-Mounted Displays multimodal 3D...

The nascent field of mixed reality is seeing an ever-increasing need for user studies and evaluation, which are particularly challenging given device heterogeneity, diversity use, mobile deployment. Immersive analytics tools have recently emerged to support such analysis in situ, yet the complexity data also warrants ex-situ using more traditional non-immersive visual setups. To bridge gap between both approaches, we introduce ReLive: a mixed-immersion framework exploring analyzing studies....

Users' cognitive load while interacting with a system is valuable metric for evaluations in HCI. We encourage the analysis of eye movements as an unobtrusive and widely available way to measure load. In this paper, we report initial findings from user study 26 participants working on three visual search tasks that represent different levels difficulty. Also, linearly increased demand solving tasks. This allowed us analyze reaction individual task Our results show how pupil dilation, blink...

Building data analysis skills is part of modern elementary school curricula. Recent research has explored how to facilitate children's understanding visual representations through completion exercises which highlight links between concrete and abstract mappings. This approach scaffolds visualization activities by presenting a target children. But can we engage children in more free-form mapping that are driven their own ideas? How scaffold creative exploration techniques possibilities? We...

Cross-device collaboration with tablets is an increasingly popular topic in HCI. Previous work has shown that tablet-only can be improved by additional shared workspace on interactive tabletop. However, large tabletops are costly and need space, raising the question to what extent physical size of horizontal surfaces really pays off. In order analyse suitability smaller-than-tabletop devices (e.g. tablets) as a low-cost alternative, we studied effect users' attention, awareness, efficiency...

Augmented reality (AR) can create the illusion of being virtually co-located during remote collaboration, e.g., by visualizing co-workers as avatars. However, spatial awareness each other's activities is limited physical spaces, including position devices, are often incongruent. Therefore, alignment methods needed to support on devices. In this paper, we present concept Re-locations, a method for enabling collaboration with augmented in incongruent spaces. The idea enrich multiple devices...

Smartphones conveniently place large information spaces in the palms of our hands. While research has shown that larger screens positively affect spatial memory, workload, and user experience, smartphones remain fairly compact for sake device ergonomics portability. Thus, we investigate use hybrid interfaces to virtually increase available display size by complementing smartphone with an augmented reality head-worn display. We thereby combine benefits familiar touch interaction near-infinite...

Handheld Augmented Reality (AR) displays offer a see-through option to create the illusion of virtual objects being integrated into viewer's physical environment. Some AR display technologies also allow for deactivation option, turning tablets Virtual (VR) devices that integrate an exclusively Both configurations are typically available on handheld devices, raising question their influence users' experience during collaborative activities. In two experiments, we studied how different user...

Abstract Adaptive visualization and interfaces pervade our everyday tasks to improve interaction from the point of view user performance experience. This approach allows using several inputs, whether physiological, behavioral, qualitative, or multimodal combinations, enhance interaction. Due multitude approaches, we outline current research trends inputs used adapt visualizations interfaces. Moreover, discuss methodological approaches in mixed reality, physiological computing, visual...

In image quality assessment, a collective visual score for an or video is obtained from the individual ratings of many subjects. One commonly used format these experiments two-alternative forced choice method. Two stimuli with same content but differing are presented sequentially side-by-side. Subjects asked to select one better quality, and when uncertain, they required guess. The relaxed alternative aims reduce cognitive load noise in responses due guessing by providing third response...

Abstract With increasing complexity in visual computing tasks, a single device may not be sufficient to adequately support the user’s workflow. Here, we can employ multi-device ecologies such as cross-device interaction, where workflow split across multiple devices, each dedicated specific role. But what makes these compelling? Based on insights from our research, or interface component must contribute complementary characteristic increase quality of interaction and further users their...

Cross-device interaction with tablets is a popular topic in HCI research. Recent work has shown the benefits of including multiple devices into users' workflows while various techniques allow transferring content across devices. However, users are only reluctantly using combination. At same time, research on cross-device struggles to find frame reference compare or systems. In this paper, we try address these challenges by studying interplay techniques, device utilization, and task-specific...

Programming assignments in computer science courses are often processed pairs or groups of students. While working together, students face several shortcomings today's software: The lack real-time collaboration capabilities, the setup time development environment, and use different devices operating systems can hamper when together on assignments. Text processing platforms like Google Docs solve these problems for writing process prose text, computational notebooks Colaboratory data analysis...

Supporting remote collaboration through augmented reality facilitates the experience of co-presence by presenting collaborator’s avatar in user’s physical environment. While visual user representations are continuously researched and advanced, audio configuration – especially combination with different visualizations is rarely considered. In a study (n = 48, 24 dyads), we evaluate two (Simple vs. Rich Avatar) auditory (Mono Spatial Audio) representations, to investigate their impact on...

Augmented Reality (AR) supported collaboration is a popular topic in HCI research. Previous work has shown the benefits of collaborative 3D object manipulation and identified two possibilities: Either separate or compose users' inputs. However, their experimental comparison using handheld AR displays still missing. We, therefore, conducted an experiment which we tasked 24 dyads with collaboratively positioning virtual objects three techniques: 1) Separation – performing only different tasks...
