Zwei Beiträge auf der TEI Conference 2018 in Stockholm, Schweden

Die Conference on Tangible, Embedded and Embodied Interaction (TEI) befasst sich mit aktuellen Fragen der Mensch-Computer-Interaktion, neuen Tools und Technologien, interaktiver Kunst und neuartiger User Experience. Die auf der TEI präsentierten Arbeiten hat einen starken Fokus darauf, wie digitale Medien in die physikalische Umgebung eingebettet werden und begreifbar gemacht werden können. Die Konferenz bietet daher ein einzigartiges Forum für den Ideenaustausch und präsentiert innovative Arbeiten durch Gespräche, interaktive Exponate, Demos, Hands-on Studios, Plakate, Kunstinstallationen und Performances.

Daniel Reinhardt und Jörn Hurtienne präsentierten ihr Paper „The Impact of Tangible Props on Gaming Performance and Experience in Gestural Interaction“, welches mit einem Honourable Mention Award ausgezeichnet wurde.

Abstract:

There is a widely-held belief in the TEI and games communities that using tangible props enhances the player performance and gaming experience. Building on prior research in gaming, we studied people playing a video game using a gestural interface without props, with an incomplete or a complete tangible prop. The interaction with the tangibles was judged to be more natural, led to higher flow experience and was preferred, but there were no differences regarding performance, enjoyment, autonomy, presence and mental effort. There was a tendency that especially the incomplete tangible prop was judged as less intuitive and people felt less competent in gameplay. In contrast to prior research, the results show that tangible interaction is not always more beneficial than gestural interaction and that, especially for incomplete tangibles, any beneficial effects may be domain-dependent.

Diana Löffler präsentierte ihre aktuellen Forschungserkenntnisse zum Thema „Multimodal Effects of Color and Haptics on Intuitive Interaction with Tangible User Interfaces“.

Abstract:

Tangible User Interfaces (TUIs) allow users to sense and manipulate digital information through physical objects. Although haptic properties are emphasized, TUIs are presented in and perceived through multiple modalities. Especially visual properties like color shape the users expectations about the relation between tangibles and the abstract data they represent and control. Viewing TUIs as multisensory percepts, we present an empirical study that quantifies benefits of an explicit design for color for intuitive interaction. In a cross-cultural experiment, 75 participants (Germans and Japanese) matched tangible objects of different colors, sizes, weights or temperatures with abstract words. The results indicate that multimodal representations increase the efficiency, effectiveness and user satisfaction, but only if colors and haptic properties evoke congruent associations. Incongruently designed tangibles led to a 17% increase in response speed, -28% lower accuracy and -61% lower preference ratings compared to congruently designed tangibles.
