DESCRIPTION:In this talk\, I’d like to present two very diverse topics: 
 API usability evaluation and collaborative faceted search around the table
 top. \n\nFirst\, I will present the Concept Maps method as a longitudinal 
 evaluation and assessment method to elicit the programmer’s mental model
  of an API. Application programming interfaces (APIs) are the interfaces t
 o existing code structures\, such as widgets\, frameworks\, or toolkits. T
 herefore\, they very much do have an impact on the quality of the resultin
 g system. The Concept Maps approach asks developers to visualize their und
 erstanding of an API by creating a concept map\, showing the relationship 
 between the API and their own code. Thereby\, we can to identify misconcep
 tions and problematic areas and by using a longitudinal study design\, we 
 can assess how these are changing over time. \n\nIn the second part\, I wi
 ll introduce “Facet-Streams”\, a hybrid interactive surface for co-loc
 ated collaborative product search on a tabletop. Facet-Streams combines te
 chniques of information visualization with tangible and multi-touch intera
 ction to materialize collaborative search on a tabletop. It harnesses the 
 expressive power of facets and Boolean logic without exposing users to com
 plex formal notations. In two user studies we were able to show how Facet-
 Streams unifies visual and tangible expressivity with simplicity in intera
 ction\, supports different strategies and collaboration styles\, and turns
  product search into a fun and social experience.\n
