    Evaluating Pointing Modes and Frames of Reference for Remotely Supporting an Augmented Reality User in a Collaborative (Virtual) Environment
    (Mensch und Computer 2019 - Tagungsband, 2019) Brown, Gordon; Prilla, Michael
    With the availability of powerful and affordable Augmented Reality (AR) devices, scenarios have become popular in which people wearing AR devices are supported by remote experts. These experts often use 2D peripherals to access the video feed of the 3D head mounted device (HMD) and to augment it with verbal or digital information. This raises the question whether tools that work for these scenarios also work for remote consultations. We conducted a study to (re--)evaluate these tools in a furniture sales consultation context. We focused on the consultant side of these settings and explored how the use of different pointing methods and perspectives affect different situations during a consultation. For this, we developed and evaluated a prototype with ten furniture store workers. Initial results show that while most usability and task load scores were even, the participants reported clear favorites for certain settings. We use these results to derive design recommendations for similar future projects.

    Using MQTT for Platform Independent Remote Mixed Reality Collaboration
    (Mensch und Computer 2019 - Workshopband, 2019) Waldow, Kristoffer; Fuhrmann, Arnulph
    In this paper, we present a Mixed Reality telepresence system that allows the connection of multiple AR or VR devices to create a shared virtual environment by using the simple MQTT networking protocol. It follows a subscribe-publish pattern for reliable and easy platform independent integration. Therefore, it is possible to realize different clients that handle communication and allow remote collaboration. To allow embodied natural human interaction, the system maps the human interaction channels, gestures, gaze and speech, to an abstract stylized avatar by using an upper body inverse kinematic approach. This setup allows spatially separated persons to interact with each other via an avatar-mediated communication.
