abstract = {Eine positive User Experience im Umgang mit einem Produkt ist oft ein ausschlaggebender Punkt, der über den Erfolg und die Verbreitung des Produkts mitentscheidet. Besonders viel Potential liegt dabei in der Weiterentwicklung der Mensch-Fahrzeug-Interaktion, da zukünftige Fahrzeuge sich noch stärker an die Bedürfnisse des Nutzers anpassen werden. Hier stellen wir das Konzept des empathischen Assistenten vor, der ähnlich einem zuvorkommenden Beifahrer die Bedürfnisse des Nutzers erkennt und darauf eingehen kann. Der empathische Assistent kann mithilfe verschiedener Sensorik unterschiedliche emotionale, mentale oder physiologische Zustände des Menschen im Fahrzeug erkennen und im Kontext interpretieren. Daraus leitet er Bedürfnisse des Nutzers ab und wendet kontext-spezifische Strategien an, welche die User Experience des Menschen im Auto verbessern. In unserem Vortrag stellen wir Use Cases aus verschiedenen Automatisierungsgraden vor, in denen der empathische Assistent zum Einsatz kommt. Dabei stellen wir Methoden zur Erkennung und Verbesserung der Nutzerzustände vor, die wir zusammen mit mehreren Partnern im Rahmen zweier öffentlich-geförderter Forschungsprojekte (F-RELACS und AutoAkzept) entwickeln. Unser Fokus liegt dabei sowohl auf Unsicherheitsempfinden und dessen Linderung beim automatisierten Fahren als auch auf der Erkennung von Frustration und deren Linderung.},
