Agenda Where interaction fits Query formulation Selection part 1: Snippets Selection part 2: Result sets  Examination

Mainly about both DBMS and reliability Mainly about DBMS, discusses reliability Mainly about, say, banking, with a subtopic discussion on DBMS/Reliability Mainly about high-tech layoffs TileBars Topic: reliability of DBMS (database systems) Query terms: DBMS, reliability DBMS reliability DBMS reliability DBMS reliability DBMS reliability

Some Good Advice Human-Computer Interaction User in control –Anticipatable outcomes –Explainable results –Browsable content –Informative feedback –Easy reversal Limit working memory load –Show query context Support for learning –Novice and expert alternatives –Scaffolding Interactive IR Support human reasoning –Show actual content –Depict uncertainty –Be fast Use familiar metaphors –Timelines, ranked lists, maps, … Some system initiative –Loosely guide the process –Expose structure of knowledge Co-design w/search strategies Credit: Ben Shneiderman

Four Simple Ideas Show the query in the selection interface –It provides context for the display Suggest options to the user –Query refinements, for example Explain what the system has done –Highlight query terms in the results, for example Complement what the system has done –Users add value by doing things the system can’t –Expose the information users need to judge utility
