    Can WebVR further the adoption of Virtual Reality?
    (Mensch und Computer 2018 - Usability Professionals, 2018) Dibbern, Christian; Uhr, Manuela; Krupke, Dennis; Steinicke, Frank
    The market for Head Mounted Displays (HMDs) as a means to experience Virtual Reality has grown tremendously over the past years. HMDs operate on their own platform (e.g. Cardboard, Vive), even though interaction techniques are similar across platforms and each platform has to be programmed individually. Manufacturers also advertise their HMDs with exclusive apps and games for their own platform. Though game engines like Unity or Unreal provide unified APIs to ease cross-platform development, the VR software market is still pretty scattered through the different platforms. The biggest challenge for VR right now is not hardware, but the slow growth in content that appeals to a mass audience, combined with the confusion associated with a lack of cross-platform support (Jiteshi Ubrani). Because of its inherent openness, the web can be a means to tackle this problem. Developers and consumers could have easier access to VR. In this article I explore how the web and VR can benefit each other.

    Designing an Interactive Visualization for Coordinating Road Construction Sites in Virtual Reality
    (Mensch und Computer 2019 - Workshopband, 2019) Uhr, Manuela; Haselmann, Sina; Steep, Lea; Eikhoff, Joschka; Steinicke, Frank
    Road works highly affect traffic in major cities, therefore coordination is key to avoid congestion on urban streets and highways. Software tools and interactive visualizations giving insight to complex road works data as well as preexisting spatial and temporal dependencies in between sites are important for the coordination process. In existing 2D visualizations, spatio-temporal dependencies are shown in multiple views, resulting in high cognitive load. In this article we describe the design and evaluation of a visualization using Virtual Reality for exploring multi-dimensional data of road works. The relevance for expert use was reviewed in an interview with local traffic engineers. In addition, a user study was conducted to evaluate the general usability of the prototype. The results reflect an overall positive response and acceptance and show directions for further development.

    VRoadworks - Interactive Data Visualization for Coordinating Construction Sites in Virtual Reality
    (Mensch und Computer 2019 - Tagungsband, 2019) Uhr, Manuela; Haselmann, Sina; Steep, Lea; Eikhoff, Joschka
    This work describes the use case, design and development of a virtual reality application for the visualization of multi-dimensional road works data. For successfully coordinating construction sites affecting roads and traffic, spatial and temporal dependencies need to be considered. In widely used 2D visualizations such as Gantt-charts and digital map tools, the relevant data and dependencies cannot be shown at once or well associated resulting in high cognitive load. Therefore a 3D interactive visualization with multiple map layers was designed and developed using virtual reality. The usability of the prototype was evaluated in a small user study and expert interview.
