Virtual monitors vs. physical monitors: an empirical comparison for productivity work

Virtual monitors can display information through a head-worn display when a physical monitor is unavailable or provides insufficient space. Low resolution and restricted field of view are common issues of these displays. Such issues reduce readability and peripheral vision, leading to increased head movement when we increase the display size. This work evaluates the performance and user experience of a virtual monitor setup that combines software designed to minimize graphical transformations and a high-resolution virtual reality head-worn display. Participants performed productivity work across three approaches: Workstation, which is often used at office locations and consists of three side-by-side physical monitors; Laptop, which is often used in mobile locations and consists of a single physical monitor expanded with multiple desktops; and Virtual, our prototype with three side-by-side virtual monitors. Results show that participants deemed Virtual faster, easier to use, and more intuitive than Laptop, evidencing the advantages of head and eye glances over full content switches. They also confirm the existence of a gap between Workstation and Virtual, as Workstation achieved the highest user experience. We conclude with design guidelines obtained from the lessons learned in this study

Design guidelines for limiting and eliminating virtual reality-induced symptoms and effects at work: a comprehensive, factor-oriented review

Virtual reality (VR) can induce side effects known as virtual reality-induced symptoms and effects (VRISE). To address this concern, we identify a literature-based listing of these factors thought to influence VRISE with a focus on office work use. Using those, we recommend guidelines for VRISE amelioration intended for virtual environment creators and users. We identify five VRISE risks, focusing on short-term symptoms with their short-term effects. Three overall factor categories are considered: individual, hardware, and software. Over 90 factors may influence VRISE frequency and severity. We identify guidelines for each factor to help reduce VR side effects. To better reflect our confidence in those guidelines, we graded each with a level of evidence rating. Common factors occasionally influence different forms of VRISE. This can lead to confusion in the literature. General guidelines for using VR at work involve worker adaptation, such as limiting immersion times to between 20 and 30 min. These regimens involve taking regular breaks. Extra care is required for workers with special needs, neurodiversity, and gerontechnological concerns. In addition to following our guidelines, stakeholders should be aware that current head-mounted displays and virtual environments can continue to induce VRISE. While no single existing method fully alleviates VRISE, workers' health and safety must be monitored and safeguarded when VR is used at work

Smart Technologies for Precision Assembly

This open access book constitutes the refereed post-conference proceedings of the 9th IFIP WG 5.5 International Precision Assembly Seminar, IPAS 2020, held virtually in December 2020. The 16 revised full papers and 10 revised short papers presented together with 1 keynote paper were carefully reviewed and selected from numerous submissions. The papers address topics such as assembly design and planning; assembly operations; assembly cells and systems; human centred assembly; and assistance methods in assembly
