    A Camera-Based Mobility Aid for Visually Impaired People
    (KI - Künstliche Intelligenz: Vol. 30, No. 1, 2016) Schwarze, Tobias; Lauer, Martin; Schwaab, Manuel; Romanovas, Michailas; Böhm, Sandra; Jürgensohn, Thomas
    We present a wearable assistance system for visually impaired persons that perceives the environment with a stereo camera system and communicates obstacles and other objects to the user in form of intuitive acoustic feedback. The system is designed to complement traditional assistance aids. We describe the core techniques of scene understanding, head tracking, and sonification and show in an experimental study that it enables users to walk in unknown urban terrain and to avoid obstacles safely.

    Perception for Everyday Human Robot Interaction
    (KI - Künstliche Intelligenz: Vol. 30, No. 1, 2016) Worch, Jan-Hendrik; Bálint-Benczédi, Ferenc; Beetz, Michael
    The ability to build robotic agents that can perform everyday tasks heavily depends on understanding how humans perform them. In order to achieve close to human understanding of a task and generate a formal representation of it, it is important to jointly reason about the human actions and the objects that are being acted on. We present a robotic perception framework for perceiving actions performed by a human in a household environment that can be used to answer questions such as “which object did the human act on?” or “which actions did the human perform?”. To do this we extend the RoboSherlock framework with the capabilities of detecting humans and objects at the same time, while simultaneously reasoning about the possible actions that are being performed.

    Companion-Technology for Cognitive Technical Systems
    (KI - Künstliche Intelligenz: Vol. 30, No. 1, 2016) Biundo, Susanne; Wendemuth, Andreas
    We introduce the Transregional Collaborative Research Centre “Companion-Technology for Cognitive Technical Systems”—a cross-disciplinary endeavor towards the development of an enabling technology for Companion-systems. These systems completely adjust their functionality and service to the individual user. They comply with his or her capabilities, preferences, requirements, and current needs and adapt to the individual’s emotional state and ambient conditions. Companion-like behavior of technical systems is achieved through the investigation and implementation of cognitive abilities and their well-orchestrated interplay.

    Information Density and Linguistic Encoding (IDeaL)
    (KI - Künstliche Intelligenz: Vol. 30, No. 1, 2016) Crocker, Matthew W.; Demberg, Vera; Teich, Elke
    We introduce IDeaL (Information Density and Linguistic Encoding), a collaborative research center that investigates the hypothesis that language use may be driven by the optimal use of the communication channel. From the point of view of linguistics, our approach promises to shed light on selected aspects of language variation that are hitherto not sufficiently explained. Applications of our research can be envisaged in various areas of natural language processing and AI, including machine translation, text generation, speech synthesis and multimodal interfaces.

    Desiderata for the Design of Companion Systems
    (KI - Künstliche Intelligenz: Vol. 30, No. 1, 2016) Rösner, Dietmar; Haase, Matthias; Bauer, Thomas; Günther, Stephan; Krüger, Julia; Frommer, Jörg
    We report about evaluations of the LAST MINUTE corpus which comprises multimodal recordings (audio, video, biopsychological data, verbatim transcripts, psychological questionnaires, in-depth user interviews) of Wizard of Oz simulated naturalistic human companion interactions in German. Based on the results of these analyses we discuss consequences for the design of future companion systems.
