    An e-marketplace system for efficient, sustainable rural logistics and mobility, based on cyber-physical contracts: Enhancing rural infrastructure by connecting stakeholders on a privacy-focused web platform
    (INFORMATIK 2024, 2024) Kopp, Sam; Schneider, Jens; Dartmann, Guido; Creutz, Lars
    Due to demographical changes and urbanisation, rural areas often lack sufficient transportation and mobility infrastructure compared to urban regions. As a result, residents feel more socially excluded and need to travel longer distances to access basic goods and services with private car use as the only viable option. This situation is a significant driver of carbon emissions among rural populations. In this paper, we present an e-marketplace system, that aims to help in reducing the number of trips by connecting regional stakeholders and using local resources more efficiently. Our approach focuses on self-organising communities while following high standards of privacy and security. We use cyber-physical contracts within a decentralised network for communication between users and show how this network of services can be represented on a web platform for everyone to access and participate.

    Investigating Freehand Pan and Zoom

    The availability of low-cost and flexible tracking systems for hand and body movements is increasing. With this, more thorough investigations for more natural and efficient physical interaction styles are required which take particular limitations of such systems into account, such as the limited ability to track individual fingers. To contribute to this, we describe an investigation of basic hand gestures for the exploration of large information spaces. A set of four pan-and-zoom alternatives using two-handed gestural controls have been implemented and compared using Google Earth as an example. For this we conducted a small-scaled formative user study with nine participants to fundamentally assess users' acceptance and the qualification of these freehand gestures for pan-and-zoom operations. As a result, a simple forward and backward hand movement for zooming and a joystick metaphor for panning yielded in the best overall results. Especially the seamless integration of continuous pan and zoom was positively highlighted by participants.
