    Embodiment or Manipulation? Understanding Users' Strategies for Free-Hand Character Control
    (Mensch und Computer 2019 - Tagungsband, 2019) Walther-Franks, Benjamin; Döring, Tanja; Yilmaz, Meltem; Malaka, Rainer
    Controlling a virtual character with your free hands is a useful task for many 3D applications such as games, computer puppetry, or emerging virtual reality applications. So far, only specialist controls have been established in the animation industry. Yet little is known about novices mental models for character control, a key to designing widely usable natural and expressive interfaces. To this end we conducted a gesture elicitation study with twelve participants performing mid-air gestures for thirteen given character motions. The mental models observed fall into two distinct categories: 1) external manipulation of an imagined physical puppet and 2) the gesturing hands embodying the motion of the virtual body part being "controlled". The employed mental model determined hand posture and the mental transformation from gesture to character motion. We present and discuss a gesture set that can inform virtual puppetry interfaces for various application domains.

    MTLG – Helping students and teachers creating and analysing simulations and games from a didactical and technical perspective
    (DELFI 2019, 2019) Leonhardt, Thiemo; Ehlenz, Matthias; Röpke, René; Bergner, Nadine; Schroeder, Ulrik
    MTLG is a framework for the creation of animations, simulations and games that focuses on simple operation through multi-touch input, support for didactic implementation and the evaluation of learning data. The framework is completely web-based and therefore system and platform independent. Over several years, prospective computer science teachers and computer science students have used the framework in our e-learning labs and seminars. We have iteratively improved and enhanced the framework and its applications over several use cases in various computer science classes. The framework and all learning applications are available as open educational resources.

    Parameterized Facial Animation for Socially Interactive Robots
    (Mensch und Computer 2015 – Proceedings, 2015) Wittig, Steffen; Rätsch, Matthias; Kloos, Uwe
    Socially interactive robots with human-like speech synthesis and recognition, coupled with humanoid appearance, are an important subject of robotics and artificial intelligence research. Modern solutions have matured enough to provide simple services to human users. To make the interaction with them as fast and intuitive as possible, researchers strive to create transparent interfaces close to human-human interaction. Because facial expressions play a central role in human-human communication, robot faces were implemented with varying degrees of human-likeness and expressiveness. We propose a way to implement a program that believably animates changing facial expressions and allows to influence them via inter-process communication based on an emotion model. This will can be used to create a screen based virtual face for a robotic system with an inviting appearance to stimulate users to seek interaction with the robot.
