    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.

    Natural 3D Interaction Techniques for Locomotion with Modular Robots
    (Mensch und Computer 2015 – Proceedings, 2015) Krupke, Dennis; Lubos, Paul; Bruder, Gerd; Zhang, Jianwei; Steinicke, Frank
    Defining 3D movements of modular robots is a challenging task, which is usually addressed with computationally expensive algorithms that aim to create self-propelling locomotion. So far only few user interfaces exist which allow a user to naturally interact with a modular robot in real-time. In this paper we present two approaches for baseline research of 3D user interfaces for intuitive manipulation of 3D movements of a modular chain-like robot in the scope of an iterative design process. We present a comparative evaluation of the techniques, which shows that they can provide intuitive human-robot interaction via remote control for real-time guidance of modular robots to move through heavy terrains and pass obstacles. In particular, our results show that steering a robot’s locomotion via rotational hand movements has benefits for challenging locomotion tasks compared to translational hand movements. We discuss the results and present lessons learned for steering user interfaces for modular robots.
