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.

Holt, Jerred, Bennett, Kevin and Flach, John (2011): Ambiguity and Content Mapping among Display Types. In: Proceedings of the Human Factors and Ergonomics Society 55th Annual Meeting 2011. pp. 390-393.

Abstract: The present study examines the efficacy of four display types. We tested digital, bar graph, polar graphic (Coury, Boulette,&Smith, 1989) and a coordinate display type. Participants completed a state classification task as described by Coury et al. Results indicate a clear performance difference among displays. The coordinate display showed significantly higher response accuracy and lower response times. The polar graphic display performed the poorest on both outcomes. Bar and digital displays demonstrated approximately equivalent performance. These results lend further support to the importance of ecological interface design and are consistent with the principles of semantic mapping. Directions for further study are discussed.

Buttigieg, Mary Anne, Sanderson, Penelope and Flach, John (1988): Object vs Separate Displays for Process Failure Detection: The Emergent Features Approach. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1340-1344.

Two studies are described that compare a "compatibility of proximity" approach to display design with an emergent features approach. Results suggest that tasks requiring integration are not necessarily better supported by an integral or object display than a separated display. A bar graph with a strong emergent feature mapped onto a goal-relevant task invariant supported better integrated task performance than a triangle display that in previous research had shown superiority when compared with weaker bar graph displays. Further research in progress is outlined. Our findings suggest that an emergent features approach to display design might be a more encompassing approach than one based solely on compatibility of proximity.
