Profil

Zusammenfassung

Robert Stock erforscht die Schnittstellen zwischen Behinderung, Medien und Digitalisierung. Er untersucht, wie Technologien – von Cochlea-Implantaten über Videokonferenzen bis zu urbanen Mobilitätssystemen – Menschen mit unterschiedlichen Fähigkeiten einbeziehen oder ausschließen, und entwickelt dabei kritische Perspektiven auf Design und Partizipation in technologischen Systemen.

• Long‐Range Transport of Giant Vesicles along Microtubule Networks

  2011

  ChemPhysChem · 34 Zitationen · DOI

  We report on a minimal system to mimic intracellular transport of membrane-bounded, vesicular cargo. In a cell-free assay, purified kinesin-1 motor proteins were directly anchored to the membrane of giant unilamellar vesicles, and their movement studied along two-dimensional microtubule networks. Motion-tracking of vesicles with diameters of 1-3 μm revealed traveling distances up to the millimeter range. The transport velocities were identical to velocities of cargo-free motors. Using total internal reflection fluorescence (TIRF) microscopy, we were able to estimate the number of GFP-labeled motors involved in the transport of a single vesicle. We found that the vesicles were transported by the cooperative activity of typically 5-10 motor molecules. The presented assay is expected to open up further applications in the field of synthetic biology, aiming at the in vitro reconstitution of sub-cellular multi-motor transport systems. It may also find applications in bionanotechnology, where the controlled long-range transport of artificial cargo is a promising means to advance current lab-on-a-chip systems.

• Rethinking Assistive Technologies: Users, Environments, Digital Media, and App-Practices of Hearing

  2021

  NanoEthics · 26 Zitationen · DOI

  Abstract Against the backdrop of an aging world population increasingly affected by a diverse range of abilities and disabilities as well as the rise of ubiquitous computing and digital app cultures, this paper questions how mobile technologies mediate between heterogeneous environments and sensing beings. To approach the current technological manufacturing of the senses, two lines of thought are of importance: First, there is a need to critically reflect upon the concept of assistive technologies (AT) as artifacts providing tangible solutions for a specific disability. Second, the conventional distinction between user and environment requires a differentiated consideration. This contribution will first review James Gibson’s concept of “affordances” and modify this approach by introducing theories and methods of Science and Technology Studies (STS) and Actor-Network Theory (ANT). Then, we present two case studies where we explore the relations between recent “assistive” app technologies and human sensory perception. As hearing and seeing are key in this regard, we concentrate on two specific media technologies: ReSound LINX 2 , a hearing aid which allows for direct connect (via Bluetooth) with iPhone, iPad, or iPod Touch, and Camassia, an IOS app for sonic wayfinding for blind people. We emphasize the significance of dis-/abling practices for manufacturing novel forms of hearing and seeing and drawing on sources like promotional materials by manufacturers, ads, or user testimonials and reviews. Our analysis is interested in the reciprocal relationships between users and their socio-technical and media environments. By and large, this contribution will provide crucial insights into the contemporary entanglement of algorithm-driven technologies, daily practices, and sensing subjects: the production of techno-sensory arrangements.
