- Konferenzbeitrag2DGree: Rapid Prototyping for Games(Mensch & Computer 2012: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Niesenhaus, Jörg; Kahraman, Burak; Klatt, JohannesThis paper introduces 2DGree, an experimental game prototyping framework, which enables users to implement and playtest their game ideas within minutes. The framework s main purpose is the evaluation of different interaction techniques as well as methods of programming by demonstration and visual programming for the application within the context of rapid game prototyping. The core of the 2DGree framework consists of a game world editor tool and a script editor, which can be connected to further components like game asset sharing platforms or evaluation tools. The paper describes the current stage of the framework development, presents a user test and provides an outlook on the future plans for the framework development and application.
- Konferenzbeitrag3D Hand Gesture Recognition Based on Sensor Fusion of Commodity Hardware(Mensch & Computer 2012: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Caputo, Manuel; Denker, Klaus; Dums, Benjamin; Umlauf, GeorgWith the advent of various video game consoles and tablet devices gesture recognition got quite popular to control computer systems. E.g. touch screens allow for an intuitive control of small 2d user interfaces with finger gestures. For interactive manipulation of 3d objects in a large 3d projection environment a similar intuitive 3d interaction method is required. In this paper, we present a dynamic 3d hand and arm gesture recognition system using commodity hardware. The input data is captured with low cost depth sensors (e.g. Microsoft Kinect) and HD color sensors (e.g. Logitech C910). Our method combines dynamic hand and arm gesture recognition based on the depth sensor with static hand gesture recognition based on the HD color sensor.
- Workshopbeitrag3DOD: A haptic 3D Obstacle Detector for the Blind(Mensch & Computer 2012 – Workshopband: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Zeng, Limin; Weber, GerhardIn this article, we propose a haptic 3D obstacle detector for the blind, which combines an off-the-shelf 3D Time-of-Flight (ToF) camera and a novel 2D tactile display. The system detects objects in up to 7 meters, and renders the spatial layout of obstacles in a non-visual interface, allowing users to choose a route independently to avoid varied obstacles, including hanging obstacles.
- KonferenzbeitragA Comparison of Spatial Grouping Techniques on Interactive Surfaces(Mensch & Computer 2012: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Höchtl, Anita; Geyer, Florian; Reiterer, HaraldIn this paper we report a comparative study investigating two interaction techniques for grouping items spatially on a tabletop interface. We compared a container technique with a proximity technique. The container concept was considered due to its familiarity with desktop systems, while the proximity technique is a novel organic concept based on spatial proximity. Our goal was to identify the characteristics of both techniques in regard to grouping and regrouping performance, grouping strategies as well as bimanual and multi-finger input. Our results indicate that the traditional container concept may not be an adequate fit for harnessing the benefits of interactive surfaces. Rather, our study shows that more informal spatial techniques based on proximity open up a promising design space for further investigations.
- KonferenzbeitragA Zooming Concept for an Interactive Non-linear Video Authoring Software(Mensch & Computer 2012: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Meixner, Britta; Grill, Christoph; Kosch, HaraldAuthoring tools for interactive non-linear videos or hypervideos often use the graph-based pattern for defining the structure between single elements of the multimedia-presentation. Visualization improvements like zooming and focus+context are rarely used. Elements of one category (for example videos, images, etc.) are represented by one uniform-looking icon, which makes it difficult to find elements in larger projects. This work illustrates that semantic and geometric zooming in combination with overview+detail views and a fisheye zoom are able to increase the attractiveness of the GUI and decrease the task completion time for several tasks.
- KonferenzbeitragEin AAL-Projekt aus sozio-technischer Sicht: Erkenntnisse und Anforderungen(Mensch & Computer 2012 – Workshopband: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Prilla, MichaelDieser Beitrag beschreibt Ergebnisse des Projekts service4home, in dem mit Pen&Paper-Technologie Dienstleistungen für Senioren bereitgestellt wurden. Er diskutiert diese Ergebnisse aus der Perspektive sozio-technischer Phänomene und beschreibt Anforderungen aus dieser Perspektive, die bisher im Bereich AAL zu wenig beachtet werden.
- KonferenzbeitragAAL: Interaktiv. Sozial. Intergenerational?(Mensch & Computer 2012 – Workshopband: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Budweg, Steffen; Burkhard, Martin; Koch, Michael; Kötteritzsch, Anna; Richter, Alexander; Ziegler, JürgenSeit 2007 fördert das transnationale „Ambient Assisted Living Joint Programme (AAL-JP)“ innovative Konzepte, Produkte und Dienstleistungen zur Sicherung der Lebensqualität einer alternden Gesellschaft in Europa. Im Mittelpunkt stehen die Entwicklung, Bereitstellung und Evaluation von Informations- und Kommunikationstechnologien (IKT) und damit verbundenen Dienstleistungen zur Stärkung der Selbstbestimmung und Autonomie älterer Menschen. Vor diesem Hintergrund wurden eine Vielzahl an Forschungs- und Praxisprojekten etabliert, mit dem Ziel ältere Menschen in ihrem täglichen Leben zu unterstützen.
- KonferenzbeitragABIS12 - Personalization and Recommendation on the Web and Beyond(Mensch & Computer 2012 – Workshopband: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Herder, Eelco; Augstein, Mirjam; Heckmann, DominikABIS 2012 is an international workshop, organized by the SIG on Adaptivity and User Modeling of the German Gesellschaft für Informatik. For the last 19 years ABIS has been a highly interactive forum for discussing the state of the art in personalization and user modeling. Latest developments in industry and research are presented in plenary sessions, forums and tutorials. Researchers, PhD students and Web professionals obtain and exchange novel ideas, expertise and feedback. ABIS 2012 is organized as part of Mensch & Computer 2012, the leading event in the area of human-computer interaction in German speaking countries.
- WorkshopbeitragAchievements in Exergames for Parkinson s Patients(Mensch & Computer 2012: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Springer, Melanie; Herrlich, Marc; Krannich, Dennis; Malaka, RainerWhile playing good games should be intrinsically rewarding, additional extrinsic rewards such as achievements if applied with care can further enhance the game experience and foster player motivation. However, if applied in an uninformed way, extrinsically induced motivation can also devalue the intrinsic rewards in the player s perception. The impact of achievements on the game experience of special target groups like older people suffering from Parkinson s disease is still largely unexplored. In this paper, two types of achievements are evaluated for the exergame Sterntaler . Sterntaler was specifically developed for patients suffering from Parkinson s disease to motivate them to do physical exercises. Our results show that the majority of the participants prefer achievements to no achievements, with a near equal split between the different types of achievements included in this study.
- KonferenzbeitragAdaptive User Interfaces on Tablets to Support People with Disabilities(Mensch & Computer 2012 – Workshopband: interaktiv informiert – allgegenwärtig und allumfassend!?, 2012) Kurschl, Werner; Augstein, Mirjam; Stitz, HolgerWith the advent of tablet computers, touch screens, gesture-based interaction and speech recognition, sophisticated applications with Natural User Interfaces (NUIs) become state of the art. NUIs have the potential to support people with disabilities, e.g., in their daily activities or in acquiring specific skills. Yet, one main challenge is that this user group has diverse abilities and handicaps so that an interaction design must be highly configurable to make NUIs beneficial. The introduction of adaptivity might be promising in order to overcome configuration complexity and effort. This paper presents an approach to adaptive user interfaces on tablets to support people with disabilities.
