Abstract-The Multifunctional and Adaptive Meal Preparation Facility (MAMPF) is a versatile and adaptive kitchen system allowing even an inexperienced user to create ambitious dishes. On the hardware side, the system controls hotplates by regulating the temperature of heated regions to turn the attention to the food actually being heated instead of the hotplate. Furthermore, the user interaction with the computer system is adapted to the requirements in a kitchen. On the work flow side, MAMPF converts a recipe into a task tree which is used to guide the user through the cooking process. By knowing the recipe, based on a formal description specially developed for this system, the optimal sequence of actions can be calculated.The system is designed to support the user without limiting spontaneity or creativity and can -if necessary -be used just like any usual stove. Consequentially, the user always retains control over the system, all settings can be overwritten at any point, and the order of the tasks can be dynamically rearranged.In order to prove the correctness of this concept, a prototype has been implemented.

Mobile Internet access via smartphones puts demands on in-car infotainment systems, as more and more drivers like to access the Internet while driving. Spoken dialog systems support the user by less distracting interaction than visual/hapticbased dialog systems. To develop an intuitive and usable spoken dialog system, an extensive analysis of the interaction concept is necessary. We conducted a Wizard of Oz study to investigate how users will carry out tasks which involve multiple applications in a speech-only, user-initiative infotainment system while driving. Results show that users are not aware of different applications and use anaphoric expressions in task switches. Speaking styles vary and depend on type of task and dialog state. Users interact efficiently and provide multiple semantic concepts in one utterance. This sets high demands for future spoken dialog systems.

Mobile Internet access via smartphones puts demands on in-car infotainment systems, as more and more drivers like to access the Internet while driving. Spoken dialog systems (SDS) distract drivers less than visual/haptic-based dialog systems. However, in conversational SDSs drivers might speak utterances which are not in the domain of the SDS and thus cannot be understood. In a Wizard of Oz study, we evaluate the effects of out-of-domain utterances on cognitive load, driving performance, and usability. The results show that an SDS which reacts as expected by the driver, is a good approach to control incar infotainment systems, whereas unexpected SDS reactions might cause severe accidents. We evaluate how a dialog initiative switch, which guides the user and enables him to reach his task goal, performs.

Im Leichtbausektor liegt der Fokus auf der Entwicklung hochfester Materialien bei geringer Masse. Dabei haben sich carbonfaserverstärkte Kunststoffe (CFK) als besonders effizient herausgestellt. Die Herstellung primärer Carbonfasern ist jedoch energie- und kostenintensiv – kostengünstiger ist die Verwendung von zu Vliesstoffen verarbeiteten recycelten Carbonfasern (rCF) für CFK-Bauteile. Nachteil: Die Festigkeitseigenschaften sind geringer als auf CF-Gelegen basierenden CFK. Die Erhöhung partieller Festigkeitseigenschaften könnte mittels gezielter Vorzugsausrichtung der rCF im Vliesstoff erreicht werden. Im Projekt ProStAir wurde der Airlay-Vliesbildungsvorgang für CF und rCF untersucht. Zentrale Frage war, ob und wie sich die Orientierung der Fasern des Vliesstoffs (Isotropieverhältnis) bei Veränderung von Herstellparametern beeinflussen lässt.
