Substituting Colour for Physical Attributes in Conceptual Metaphors for Tangible Interaction Design

Studies in tangible interaction have investigated how physical object attributes can stand for abstract content (e.g. IMPORTANT IS HEAVY). A less expensive and more practical alternative to dynamically change, for example, the size, weight or temperature of tangibles, could be using colour-to-abstract mappings. Grounded in embodied cognition theory, a number of colour-for-physical substitutions are derived (e.g. DARK COLOURS ARE HEAVY). These substitutions are then tested for their effectiveness with 15 conceptual metaphors (e.g. IMPORTANT IS DARK COLOUR). In four conditions (haptic, colour, haptic-colour congruence, haptic-colour incongruence) 48 participants matched objects of different colours, sizes, weights or temperatures with abstract words. The results indicate that colour can replace physical attributes in metaphoric mappings and that designers need to explicitly design for colour, because metaphor-incongruent colours can hamper the effectiveness of metaphorical mappings. The results also indicate that an embodied experiential view can circumvent arguing about specific colours with high-level symbolic meanings.

Soft Pillows and the Near and Dear: Physical-to-Abstract Mappings with Image-Schematic Metaphors

For interaction designers who need systematic and universal guidelines on how to express abstract meaning via the physical and spatial means of tangible user interfaces, image-schematic metaphors have been shown to be a promising approach. Rooted in the embodied status of human cognition, image-schematic metaphors generate many candidates for population stereotypes of physical-to-abstract mappings. In an empirical study complementing earlier research 80 participants matched tangible objects with abstract keywords derived from 30 image-schematic metaphors of the image schemas UP-DOWN, FRONT-BACK, NEAR-FAR, HARD-SOFT, STRONG-WEAK and STRAIGHT-CROOKED. On average, 77% of the participants’ responses were consistent with the metaphors, and 19 metaphors received agreement rates of at least 80% suggesting these to be valid population stereotypes. As agreement rates vary dependent on context, image schema instantiation and participant population, conclusions for further studies are drawn.
