abstract = {We introduce a Personal Fabrication workflow to easily create feature-rich 3D objects with textile-covered surfaces. Our approach unfolds a 3D model into a series of flat frames with connectors, which are then 3D-printed onto a piece of fabric, and folded manually into the shape of the original model. This opens up an accessible way to incorporate established 2D textile workflows, such as embroidery, using color patterns, and combining different fabrics, when creating 3D objects. FabricFaces objects can also be flattened again easily for transport and storage. We provide an open-source plugin for the common 3D tool Blender. It enables a one-click workflow to turn a user-provided model into 3D printer instructions, textile cut patterns, and connector support. Generated frames can be refined quickly and iteratively through previews and extensive options for manual intervention. We present example objects illustrating a variety of use cases.},

abstract = {Soft robotics uses soft, flexible materials and elastic actuation mechanisms to create systems that are more adaptable and tolerant to unknown environments, and safer for human-machine interaction, than rigid robots. Pneumatic soft robots can be fabricated using more affordable materials compared to traditional robots and make use of technologies such as 3D printing, making them an attractive choice for research and DIY projects. However, their design is still highly unintuitive, and at up to two days, design iterations can take prohibitively long: The behavior of, e.g., a pneumatic silicone gripper only becomes apparent after designing and 3D printing its mold, casting, curing, assembling, and testing it. We introduce SoRoCAD, a design tool supporting a Maker-friendly soft robotics design and fabrication pipeline that incorporates simulating the final actuation into the design process.},

abstract = {Previous approaches to generate shapes in a 3D setting train a GAN on the latent space of an autoencoder (AE). Even though this produces convincing results, it has two major shortcomings. As the GAN is limited to reproduce the dataset the AE was trained on, we cannot reuse a trained AE for novel data. Furthermore, it is difficult to add spatial supervision into the generation process, as the AE only gives us a global representation. To remedy these issues, we propose to train the GAN on grids (i.e. each cell covers a part of a shape). In this representation each cell is equipped with a latent vector provided by an AE. This localized representation enables more expressiveness (since the cell-based latent vectors can be combined in novel ways) as well as spatial control of the generation process (e.g. via bounding boxes). Our method outperforms the current state of the art on all established evaluation measures, proposed for quantitatively evaluating the generative capabilities of GANs. We show limitations of these measures and propose the adaptation of a robust criterion from statistical analysis as an alternative.},

abstract = {Nowadays, digitalization is increasingly finding its way into all areas of daily life. This poses new challenges for people who have little experience in dealing with digital devices, particularly senior citizens. In this paper, we introduce InfoBiTS, a native Android application that provides computer science related content for seniors and aims to foster digital competencies of seniors. In addition to basics in the use of mobile devices, the app contains four modules, whose content was selected from school curricula for computer science, topics of current relevance, interests of seniors as well as contents relevant to seniors’ day-to-day activities. The target groups’ interests and everyday life relevance are particularly important, since research in geragogics shows that they are important aspects for learning in old age. Each of the four modules combines learning content with hands-on exercises. For research purposes, different questionnaires are integrated in the application and activity data is logged and stored as xAPI statements in a Learning Analytics component. A first pilot study showed a good usability and indicated the importance of relevance to the everyday life of the target group. Furthermore, participants preferred a mixture of text and video elements as opposed to pure text modules.},

abstract = {Immer mehr technikferne Erwachsene und insbesondere Seniorinnen und Senioren nutzen Tablets und Smartphones um am digitalen Alltag teilzuhaben. Hierf\"{u}r ist eine informatische Grundbildung unerl\"{a}sslich. Diese erm\"{o}glicht technikfernen Erwachsenen, einen sicheren, kompetenten und selbstst\"{a}ndigen Umgang mit der f\"{u}r sie neuen Technologie. Unter technikfern werden hier Personen verstanden, die in ihrer Schulausbildung, beruflichen Aus- und Weiterbildung oder ihrem Beruf bzw. ihrer Freizeit in keinem oder geringen Ma\ss mit Technik, hier insbesondere Computer, Smartphone und Tablet, in Kontakt gekommen sind. In diesem Beitrag wird das Forschungsvorhaben zur Frage, wie appgest\"{u}tze Lerneinheiten technikfernen \"{a}lteren Erwachsenen ein grundlegendes/alltagsrelevantes Verst\"{a}ndnis informatischer Systeme und ihrer Wirkungen auf die Gesellschaft vermitteln k\"{o}nnen, vorgestellt. Basierend auf curricularen Empfehlungen und Handreichungen f\"{u}r digitale Bildung sowie einer Interessenserhebung bei der Zielgruppe wurde ein Curriculum f\"{u}r die informatische Grundbildung f\"{u}r technikferne Erwachsene entwickelt. Basierend auf diesem Curriculum wurden Inhalte f\"{u}r appgest\"{u}tzte Lernanwendungen ausgew\"{a}hlt. Thematisch besch\"{a}ftigen sich diese Inhalte mit Kommunikation, Internet sowie Datenschutz und Datensicherheit. Die Inhalte sind dabei in vier Module unterteilt, welche konzipiert, technisch umgesetzt sowie evaluiert werden.},

Damit unterscheidet sich die Nutzungsweise nicht sehr von der zu Zeiten vor Smartphones und Tablets. Gleichzeitig werden diese Funktionalit\"{a}ten nicht nur genutzt, sondern es besteht auch ein Interesse daran zu verstehen, wie diese funktionieren. Neben Kommunikationsm\"{o}glichkeiten und der Funktionsweise des Internets ist auch Datenschutz und Datensicherheit ein Thema, an dem ein gro\sses Interesse besteht. In unterschiedlicher Auspr\"{a}gung lassen sich in diesen Nutzungsweisen und Interessen die drei Perspektiven der Dagstuhl-Erkl\"{a}rung, die f\"{u}r die Bildung in der digitalen vernetzenWelt von Bedeutung sind, wiederfinden. Basierend auf diesen Ergebnissen kann ein Konzept zur Vermittlung von ausgew\"{a}hlten informatischen Grundkonzepten erstellt werden, welches an den Alltag der Zielgruppe und ihre Interessen ankn\"{u}pft und alle drei Perspektiven ber\"{u}cksichtigt.},
