- KonferenzbeitragDesigning for Social Interaction in Collaborative Games on Large Multi- Touch Displays(Mensch & Computer 2011: überMEDIEN|ÜBERmorgen, 2011) Herrlich, Marc; Walther-Franks, Benjamin; Weidner, Daniel; Malaka, RainerAlthough computer games enable people from all around the world to play games together and can provide very immersive virtual environments, most computer games are still played in a separate fashion quite contrary to the social events that physical games are. Large interactive surfaces can bridge this gap, bringing together the best of both worlds: highly social activity and colorful, dynamic game worlds. With this paper we contribute to research on gaming on large multi-touch displays. Based on game mechanics successfully brought to small multi-touch devices, we developed our own game intro-ducing features and gestures specifically designed for large surface and multi-player gameplay with special regard for the social interaction among players. We provide insights on the social protocol of collaborative multi-player gaming on large interactive displays by studying people playing our game. Our results suggest that communication and social interaction does not just happen by itself but must be designed into the game, taking into account the specifics of multi-touch interaction, such as non-verbal communication possibilities between players.
- KonferenzbeitragEmbodiment or Manipulation? Understanding Users' Strategies for Free-Hand Character Control(Mensch und Computer 2019 - Tagungsband, 2019) Walther-Franks, Benjamin; Döring, Tanja; Yilmaz, Meltem; Malaka, RainerControlling 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.
- KonferenzbeitragJump‘n’Rhythm: A Video Game for Training Timing Skills(Mensch und Computer 2016 – Workshopband, 2016) Alexandrovsky, Dmitry; Alvarez, Katya; Walther-Franks, Benjamin; Wollersheim, Joschua; Malaka, RainerDeveloping a sense of rhythm is a central but difficult task in music education. Even otherwise enthusiastic music students might avoid the training of their rhythm skills due to the tedious and repetitive nature of exercises. In this work we explore how a gamification approach to rhythm learning can improve the capacity of entrainment in players. Based on insights from music didactics and neuroscience we developed Jump‘n’Rhythm, a serious game for training rhythmical timing skills.
- Zeitschriftenartikel,,Raus aus dem Sessel“ – Computerspiele für mehr Gesundheit(Informatik-Spektrum: Vol. 37, No. 6, 2014) Herrlich, Marc; Wenig, Dirk; Walther-Franks, Benjamin; Smeddinck, Jan D.; Malaka, RainerComputerspiele ziehen inzwischen jung und alt gleichermaßen in ihren Bann. Betrachtet man die oftmals sehr komplexen Aufgaben, die in vielen Spielen unter Zeitdruck gelöst werden müssen und die äußerst realistische Simulation und Darstellung der virtuellen Welten in heutigen Spielen, so stellt sich die Frage, ob dieses Potenzial auch für andere Zwecke, abseits der reinen Unterhaltung, genutzt werden kann. Mit dieser Frage beschäftigt sich eine wachsende Anzahl Wissenschaftler und Computerspielehersteller schon seit einiger Zeit und über die letzten Jahre konnte sich die Bezeichnung Serious Games als Oberbegriff für diesen Bereich etablieren. Gleichzeitig eröffnet die Entwicklung von massenmarkttauglichen Eingabegeräten für die körperliche Interaktion insbesondere für die spezielle Gruppe der sog. Exergames (Exercise + Game) neue Möglichkeiten und Anwendungsgebiete. Dieser Artikel gibt einen kurzen Überblick zur Geschichte der Serious Games und insbesondere der Exergames und stellt zwei spezielle Ansätze und Anwendungsgebiete für die Entwicklung von Exergames aus der aktuellen Forschung vor: Exergames für den Einsatz in der Physiotherapie und die Nutzbarmachung herkömmlicher Vollpreisspiele als Exergames.
- mensch und computer 2013 - workshopbandSportal: A First-Person Videogame turned Exergame(Mensch & Computer 2013 - Workshopband, 2013) Walther-Franks, Benjamin; Wenig, Dirk; Smeddinck, Jan; Malaka, RainerDigital exercise games (exergames) can motivate players to carry out physical exercises. However, most exergames are controlled by confined and predefined movements and do not promote long-term motivation. Well-funded commercial games often excel at long-term motivation, but are not operated with motion input. We choose the best of both worlds by turning an existing videogame without motion control into an exergame. By adding motion-based controls and a feedback overlay to the popular firstperson action game Portal 2, and designing custom game levels around exercise regimens with the freely available Hammer editor, we turned it into the exergame Sportal. This approach can give gamers an incentive to exercise using high quality first-person gameplay and it can potentially acquaint exerciseeager non-gamers with a popular videogame title.
