    CoShare: a Multi-Pointer Collaborative Screen Sharing Tool
    (Mensch und Computer 2023 - Tagungsband, 2023) Emmert, Martina; Schmid, Andreas; Wimmer, Raphael; Henze, Niels
    Existing tools for screen sharing and remote control only allow a single user to interact with a system while others are watching. Collaborative editors and whiteboards allow multiple users to work simultaneously, but only offer a limited set of tools. With CoShare, we combine both concepts into a screen sharing tool that gives remote viewers a mouse pointer and a text cursor so that they can seamlessly collaborate within the same desktop environment. We have developed a proof-of-concept implementation that leverages Linux’ multi-pointer support so users can control applications in parallel. It also allows limited sharing of clipboard and dragging files from the remote viewer’s desktop into the video-streamed desktop. In focus groups we gathered user requirements regarding privacy, control, and communication. A qualitative lab study identified further areas for improvement and demonstrated CoShare’s utility.

    How Do Users Like Their Tangibles? An Exploration of Interaction Techniques for Data Transfer with Everyday Objects
    (Mensch und Computer 2023 - Workshopband, 2023) Emmert, Martina; Schönwerth, Nicole; Schmid, Andreas; Alesik, Anton; Wimmer, Raphael
    People interact with a multitude of personal digital devices and infrastructural hardware every day. Oftentimes, they need to transfer data from one device to another. In many cases this process is still surprisingly cumbersome, requiring additional, non-intuitive steps, such as authentication, device pairing, or network setup. Tangible User Interfaces (TUIs) allow for quick and intuitive physical interaction with digital data. Therefore, they offer a promising design space towards more natural interaction techniques for cross-device data transfer. In a workshop and an elicitation study, we investigated different form factors and interaction techniques using six everyday objects in three different situations. We found that designing effective tangibles requires consideration of various factors which strongly depend on the target group and intended use case.

    I've Got the Data in My Pocket! - Exploring Interaction Techniques with Everyday Objects for Cross-Device Data Transfer
    (Proceedings of Mensch und Computer 2024, 2024) Emmert, Martina; Schönwerth, Nicole; Schmid, Andreas; Wolff, Christian; Wimmer, Raphael
    People interact with a multitude of personal digital devices every day. However, transferring data between devices is still surprisingly cumbersome due to technical barriers, such as authentication or device pairing. Due to their clear affordances, physical devices offer a promising design space as mediators for natural interaction techniques. In a workshop and an elicitation study (n = 30), we investigated different interaction techniques for cross-device data transfer using everyday objects. Our results suggest that depending on the use case, extending always-available physical objects might be more beneficial than developing new artifacts. Designing effective interaction techniques requires consideration of an artifact’s physical characteristics, affordances, and situational surroundings. Participants preferred multi-functional objects which are always at hand, such as their smartphone. However, they opted for more impersonal objects in unfamiliar situations. Interaction techniques associated with objects also influenced users’ actions. We provide an overview of factors influencing intuitive interactions and we derived guidelines for user-centered development of interaction techniques with physical objects as mediators for data transfer.
