Fahrer benötigen zur sicheren Steuerung ihres Fahrzeugs im Straßenverkehr eine Reihe von Anzeigen. Viele Funktionen zur Fahrerassistenz benötigen Eingaben des Fahrers. Wie auch in den vergangenen Jahren die Funktionsvielfalt gewachsen ist, sind auch Anzeige und Bedienelemente gestiegen. Im vorangegangen Kapitel wurde bereits die Begrenztheit der menschlichen Leistungsfähigkeit bei der gleichzeitigen Aufnahme und Interpretation von Informationen dargelegt. Die Herausforderung an das HMI im Fahrzeug ist durch die gewachsene Anzahl und auch Komplexität der Systeme enorm gestiegen. In diesem Kapitel sollen zu ausgewählten Funktionen die Anzeige und Bedienkonzepte vorgestellt werden, von einfachen Anzeigen bis zu Strategien für das autonom fahrende Fahrzeug. Dabei wird ein besonderes Augenmerk auf die sicherheitsrelevanten Aspekte gelegt.
Starting with the automatic gear change, the operation of a vehicle becomes more and more abstract. In the future, we could control vehicles with single, simple commands. For such a maneuver-based vehicle control system, we investigate a head-up display design in a workshop. The aims are to identify common and distinct features of various display designs through mock-ups. First results show that different sizes of GUI elements are preferred by different states. The preferred position of GUI elements in the head-up display (HUD) is the central bottom area. We found two major interface design styles: static interfaces (all elements visible) with fixed layout and dynamic interfaces (only relevant elements visible) with fixed or adaptive layout.
The virtual classroom continues to grow, but it is becoming more and more the norm, and it is fundamentally different from the vocational students at the Indonesian university. With the promised benefits of the virtual classroom, many challenges and difficulties come in the implementation. Although there are already successful design principles for virtual classrooms that support organizations in overcoming the challenges, the approach to implementing the design principles of virtual classroom at the vocational higher education in Indonesia is still lacking. In this study, we aim to answer the research gap and used the design sciences research by interviewing the lecturers to design the solutions. The proposed design approaches were implemented in a course and evaluated with students from two different groups. Overall, the evaluation of the proposed approaches shows1 significant results as an indicator of the benefits of the implementation of a virtual classroom for vocational students in Indonesia.
The continuous evolution of learning technologies combined with the changes within ubiquitous learning environments in which they operate result in dynamic and complex requirements that are challenging to meet. The fact that these systems evolve over time makes it difficult to adapt to the constant changing requirements. Existing approaches in the field of Technology Enhanced Learning (TEL) are generally not addressing those issues and they fail to adapt to those dynamic situations. In this chapter, we investigate the notion of an adaptive and adaptable architecture as a possible solution to address these challenges. We conduct a literature survey upon the state of the art and state of practice in this area. The outcomes of those efforts result in an initial model of a Domain-specific architecture to tackle the issues of adaptability and adaptiveness. To illustrate these ideas, we provide a number of scenarios where this architecture can be applied or is already applied. Our proposed approach serves as a foundation for addressing future ubiquitous learning applications where new technologies constantly emerge and new requirements evolve.
Coming out of the labs, the first robots are currently appearing on the consumer market. Initially they target rather simple application scenarios ranging from entertainment to home convenience. However, one can expect, that they will capture more complex areas soon. These robots will have a higher and higher level and a broad range of functional competence, and will collaborate and interactively communicate with their human users. All this requires considerable cognitive abilities on the robot’s side and appropriate man-machine interaction technologies. Apart from further development of individual functions and technologies it is crucial to build and evaluate fully integrated systems. This paper describes our approach to construct a robotic assistance system. We present experience with an integrated technology demonstration and the exposure of the integrated system to the public.
Sensing and processing of multimedia information is one of the basic traits of human beings. The development of digital technologies and applications allows the production of huge amounts of multimedia data. The rapidly decreasing prices for hardware such as digital cameras/camcorders, sound cards and the corresponding displays led to wide distribution of multimedia-capable input and output devices in all fields of the everyday life, from home entertainment to companies and educational organisations. Thus, multimedia information in terms of digital pictures, videos, and music can be created intuitively and is affordable for a broad spectrum of users.

Film archives—particularly those storing video material on all kinds of news items—are important information sources for TV stations. Each TV station creates and maintains its own archive by storing video material received via satellite and/or internet on tapes in analogue and/or digital form. It cannot be predicted in advance which of this archived material will actually be used. Thus all material received must be catalogued and stored. On average only a small percentage of the material stored is actually used. Due to the increase in data volumes the cost of maintaining such repositories and retrieving particular stored items has become prohibitive. To-day digital videos are increasingly replacing analogue material. Digital videos offer the advantage that the can be stored in distributed databases and then be transferred without loss of quality to the transmitting station. Such digital archives can be made accessible to many TV stations, thus spreading the maintenance cost. Individual stations can retrieve only the material they actually need for particular news casts. In this paper a grid architecture for distributed video archives for news broadcasts is proposed. A crucial aspect of such a grid approach is that advanced methods for retrieving data must be available.
Multimodaler Sensor zur Fahrzeugführung: Teilprojekt: Architektur, Rundumsicht und Objekterkennung
(1997)
Kaum ein sicherheitskritisches System hat eine so große Verbreitung bei Privatpersonen gefunden wie das Automobil. Seit seiner Erfindung hat es eine rasante Weiterentwicklung erfahren, von einer rein mechanischen Maschine zu einem System, bei dem heute die meisten Innovationen auf elektronischen Komponenten basieren. Dazu zählen insbesondere Fahrerassistenzsysteme, die helfen sollen, komfortabler und sicherer am Ziel der Fahrt anzukommen. Wo einst z. B. der Tempomat einfach über die Einstellung einer festen Geschwindigkeit gesteuert wurde, sind heute bereits einzelne Systeme deutlich umfangreicher und das Zusammenspiel longitudinaler und lateraler Automatisierung führt zu einem Anstieg der Komplexität. Die sichere Bedienung des Fahrzeugs muss jedoch im Vordergrund stehen, kann ein Fehler doch schnell bis hin zu tödliche Folgen haben. In diesem Kapitel werden psychologische Grundlagen vorgestellt und auf die Herausforderungen für die Entwicklung von HMIs im Fahrzeug angewandt. Konkrete Umsetzungen von aktuellen Fahrzeugen bis hin zu Forschungsarbeiten werden betrachtet, ebenso wird auf den Entwicklungsprozess und Nutzerstudien eingegangen.
Systems for automated image analysis are useful for a variety of tasks and their importance is still growing due to technological advances and an increase of social acceptance. Especially in the field of driver assistance systems the progress in science has reached a level of high performance. Fully or partly autonomously guided vehicles, particularly for road-based traffic, pose high demands on the development of reliable algorithms due to the conditions imposed by natural environments. At the Institut für Neuroinformatik methods for analyzing driving relevant scenes by computer vision are developed in cooperation with several partners from the automobile industry. We introduce a system which extracts the important information from an image taken by a CCD camera installed at the rear view mirror in a car. The approach consists of a sequential and a parallel sensor and information processing. Three main tasks namely the initial segmentation (object detection), the object tracking and the object classification are realized by integration in the sequential branch and by fusion in the parallel branch. The main gain of this approach is given by the integrative coupling of different algorithms providing partly redundant information.
