Virtual Reality (VR) provides new possibilities for modern knowledge work. However, the potential advantages of virtual work environments can only be used if it is feasible to in them an extended period time. Until now, there are limited studies long-term effects when working VR. This paper addresses need understanding such effects. Specifically, we report on a comparative study $i$, which participants were VR entire week-for five days, eight hours each day-as well as baseline physical...
Virtual Reality (VR) has the potential to transform knowledge work. One advantage of VR work is that it allows extending 2D displays into third dimension, enabling new operations, such as selecting overlapping objects or displaying additional layers information. On other hand, mobile workers often on established devices, tablets, limiting interaction with those devices a small input space. This challenge constrained space intensified in situations when situated cramped environments,...
Learning vocabulary in a primary or secondary language is enhanced when we encounter words context. This context can be afforded by the place activity are engaged with. Existing learning environments include formal learning, mnemonics, flashcards, use of dictionary thesaurus, all leading to practice with new In this work, propose an enhancement process providing user and tools context, VocabulARy. VocabulARy visually annotates objects AR, user's surroundings, corresponding English (first...
The 'keyword method' is an effective technique for learning vocabulary of a foreign language. It involves creating memorable visual link between what word means and its pronunciation in language sounds like the learner's native However, these links remain implicit people's mind are not easy to remember large set words. To enhance memorisation recall vocabulary, we developed application that combines keyword method with text-to-image generators externalise into visuals. These visuals...
In mixed reality (MR) telepresence applications, the differences between participants' physical environments can interfere with effective collaboration. For asymmetric tasks, users might need to access different resources (information, objects, tools) distributed throughout their room. Existing intersection methods do not support such interactions, because a large portion of rooms become inaccessible, along relevant task resources. We propose MRUnion, Mixed Reality Telepresence pipeline for...
Immersive technologies like stereo rendering, virtual reality, or augmented reality (AR) are often used in the field of molecular visualisation. Modern, comparably lightweight and affordable AR headsets Microsoft's HoloLens open up new possibilities for immersive analytics A crucial factor a comprehensive analysis data is rendering speed. HoloLens, however, has limited hardware capabilities due to requirements battery life, fanless cooling weight. Consequently, insights from best practises...
Virtual Reality (VR) can enhance the display and interaction of mobile knowledge work in particular, spreadsheet applications. While spreadsheets are widely used yet challenging to interact with, especially on devices, using them VR has not been explored depth. A special uniqueness domain is contrast between immersive large space afforded by VR, contrasted very limited that may be for information worker go, such as an airplane seat or a small work-space. To close this gap, we present...
An increasing number of consumer-oriented head-mounted displays (HMD) for augmented and virtual reality (AR/VR) are capable finger hand tracking. We report on the accuracy off-the-shelf VR AR HMDs when used touch-based tasks such as pointing or drawing. Specifically, we tracking Oculus Quest, Vive Pro Leap Motion controller, attached to a HMD, well Microsoft HoloLens 2 Magic Leap. present results two experiments in which compare absolute relative using both human participants robot. The...
Virtual Reality (VR) has the potential to support mobile knowledge workers by complementing traditional input devices with a large three-dimensional output space and spatial input. Previous research on supporting VR work explored domains such as text entry using physical keyboards spreadsheet interaction combined pen touch Inspired work, this paper probes design for authoring presentations in settings. We propose PoVRPoint-a set of tools coupling pen- touch-based editing devices, tablets,...
Recent commercial virtual and augmented reality (VR / AR) devices have been promoted as tools for knowledge work research findings show that they can be beneficial. One benefit is the possibility to display screens which could especially helpful in mobile contexts, users might not access an optimal physical setup. Such situations often occur public settings, example when working on a train while traveling business meeting. However, using such still uncommon, motivates our study better...
While the promise of autonomous vehicles has led to significant scientific and industrial progress, fully automated, SAE level 5 conform cars will likely not see mass adoption anytime soon. Instead, in many applications, human supervision, such as remote monitoring teleoperation, be required for foreseeable future. Virtual Reality (VR) been proposed one potential interface its benefits drawbacks over physical teleoperation solutions have thoroughly investigated. To this end, we contribute...
Although access to sufficient screen space is crucial knowledge work, workers often find themselves with limited display infrastructure in remote or public settings. While virtual displays can be used extend the available through extended reality (XR) head-worn (HWD), we must better understand implications of working them settings from both users' and bystanders' viewpoints. To this end, conducted two user studies. We first explored usage a hybrid AR across real-world tasks. focused on how...
VR devices have recently been actively promoted as tools for knowledge workers and prior work has demonstrated that can support some worker tasks. However, only a few studies explored the effects of prolonged use such study observing 16 participants working in physical environment one work-week each reporting mainly on subjective feedback. As nuanced understanding participants' behavior how it evolves over time is still missing, we report results from an analysis 559 hours video material...
Augmented Reality (AR) and wearable sensors offer new possibilities to expand our senses change how we interact with the world. Sensory augmentation can be integrated into everyday activities, but controls remain a challenge for user experience. In this paper, investigate users control futuristic interface that enables in-situ magnification. We designed an interactive system enable zoom in on objects up microscopic level implemented prototype using Microsoft Hololens. user-study, compared...
Knowledge workers typically work on some kind of computer and other than an internet connection, they rarely need access to specific environments or devices. This makes it feasible for them also in different mobile settings, like public transportation. In such spaces comfort productivity could be decreased due hardware limitations small screen sizes input devices environmental clutter. Mixed reality (MR) has the potential solve issues. It can provide user with additional display space that...

XR has the potential to be an effective tool for knowledge work. The recent head-worn displays, along with productivity-oriented software tools, are being actively researched innovative applications in this field. In paper, we reflect on use of off-the-shelf devices scope studies focusing supporting focus long-term effects using virtual reality (VR) workplace settings, impact extended (XR) work public settings as well monitoring and teleoperation automated vehicles. insights from these...
Research on text entry in Virtual Reality (VR) has gained popularity but the efficient of accented characters, characters with diacritical marks, VR remains underexplored. Entering is supported most capacitive touch keyboards through a long press base character and subsequent selection character. However, entering those physical still challenging, as they require recall an respective numeric codes. To address this issue paper investigates three techniques to support VR. Specifically, we...
Nowadays, Mixed Reality (MR) headsets are a game-changer for knowledge work. Unlike stationary monitors, MR allow users to work with large virtual displays anywhere they wear the headset, whether in professional office, public setting like cafe, or quiet space library. This study compares four different layouts (eye level-close, eye level-far, below level-far) of regarding feelings safety, perceived productivity, and social acceptability when working public. We test which layout is most...
