“ It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them. ”

Friederichs-Büttner, Gesa, Walther-Franks, Benjamin and Malaka, Rainer (2012): An unfinished drama: designing participation for the theatrical dance performance Parcival XX-XI. In: Proceedings of DIS12 Designing Interactive Systems 2012. pp. 770-778.

“The partnership of theater and digital media shows much potential for new means of storytelling. Digital scenery can be joined to the performer's action on stage; algorithmic influences can blur the linearity of a drama; interactive technology offers novel means of involving the audience in the creation of the piece. Interaction can thus enhance the dramaturgical possibilities of traditional theater. However, the narrative task also accompanies various new challenges for the designers of such a play. On the basis of our dance performance Parcival XX-XI, we define requirements for making an audience interact in a theatrical play and introduce four interaction-enabling criteria for theatrical performances that use gestural interfaces.”

Walther-Franks, Benjamin, Herrlich, Marc, Karrer, Thorsten, Wittenhagen, Moritz, Schröder-Kroll, Roland, Malaka, Rainer and Borchers, Jan (2012): Dragimation: direct manipulation keyframe timing for performance-based animation. In: Proceedings of the 2012 Conference on Graphics Interface 2012. pp. 101-108.

“Getting the timing and dynamics right is key to creating believable and interesting animations. However, using traditional keyframe animation techniques, timing is a tedious and abstract process. In this paper we present Dragimation, a novel technique for interactive performative timing of keyframe animations. It is inspired by direct manipulation techniques for video navigation that leverage the natural sense of timing all of us possess. We conducted a user study with 27 participants including professional animators as well as novices, in which we compared our approach to two other interactive timing techniques, timeline scrubbing and sketch-based timing. Dragimation is comparable regarding objective error measurements to the sketch-based approach and significantly better than scrubbing and is the overall preferred technique by our test users.”

Walther-Franks, Benjamin, Wenig, Dirk, Malaka, Rainer and Grüter, Barbara (2009): An evaluation of authoring interfaces for image-based navigation. In: Proceedings of 11th Conference on Human-computer interaction with mobile devices and services 2009. p. 58.

“We present the development and evaluation of an authoring system for image-based pedestrian navigation which lets authors take pictures and annotate instructions on the go in three interface variants. Results indicate that a freehand manner of photograph annotation is fastest, while authors strive toward visually pleasing annotation compositions.”

Schwarten, Lasse, Walther-Franks, Benjamin, Grimmer, Christoph and Fei, Sebastian (2008): A Comparison of Motion and Keypad Interaction for Fine Manipulation on Mobile Devices. In: Proceedings of the HCI08 Conference on People and Computers XXII 2008. pp. 93-96.

“Ever since the introduction of products such as the Nintento Wii or the Nokia N95, motion-based interaction has become en vogue in research and industry alike. The employment of this new form of interaction is the subject of extensive research, especially for mobile use. Tilt or gesture interaction allow for quick and intuitive manipulation since the device is already at hand. So far there is neither a consensus on which metaphors can support input based on device motion, nor what types of applications are benefited on device motion, nor what types of applications are benefited by this control. Motion-based approaches exist for coarse tasks such as selecting an entry from a menu, but how does such an input mechanism work for finer input? Further, it is important to scrutinize whether this new way of interacting really is an improvement over tried-and-tested keypad interaction. In order to address these questions, we present a comparison of tilt-based interaction with the established keypad interface fro fine manipulation. For this we developed a new metaphor for tilt-based control we call MarbleControl, which can be used for a wide range of applications.”
