    Using Open Source Based Distributed Agents to Perform Digital Investigation in Virtual Environments
    (INFORMATIK 2017, 2017) Spiekermann, Daniel; Keller, Jörg; Eggendorfer, Tobias
    To solve the challenges of digital investigation in virtual environments, we propose the use of distributed agents to ensure valid and continuous network traffic observations in these environments. As one of the most relevant new evolution in information technology, cloud computing demands a flexible and highly dynamic infrastructure, provided by the virtualization of systems, networks and storage. However investigating computer related crime in these environments a necessity. Current techniques like computer or network forensic investigation are not suitable for these environments. The migration of virtual machines changes the environment permanently, thus every running investigation is aggravated. Our approach of open source based, distributed agents is able to implement viable investigations in these virtual environment.

    Using wrist vibrations to guide hand movement and whole body navigation
    (i-com: Vol. 13, No. 3, 2014) Brock, Anke; Kammoun, Slim; Macé, Marc; Jouffrais, Christophe
    In the absence of vision, mobility and orientation are challenging. Audio and tactile feedback can be used to guide visually impaired people. In this paper, we present two complementary studies on the use of vibrational cues for hand guidance during the exploration of itineraries on a map, and whole body-guidance in a virtual environment. Concretely, we designed wearable Arduino bracelets integrating a vibratory motor producing multiple patterns of pulses. In a first study, this bracelet was used for guiding the hand along unknown routes on an interactive tactile map. A wizard-of-Oz study with six blindfolded participants showed that tactons, vibrational patterns, may be more efficient than audio cues for indicating directions. In a second study, this bracelet was used by blindfolded participants to navigate in a virtual environment. The results presented here show that it is possible to significantly decrease travel distance with vibrational cues. To sum up, these preliminary but complementary studies suggest the interest of vibrational feedback in assistive technology for mobility and orientation for blind people.
