Evaluation: Procedure
Mental models recorded using Teach-Back protocol
I “What is?” - semantic knowledgeI “How to?” - procedural knowledge
1. Performing list of predefined tasks while thinking aloud2. Exploration of system and checking of assumptions3. Elicitation of mental models and interview

Discussion
I “Simple way” of making connectionsI Connector object
• Part of system• “carry” content between devices
I Spotlight Navigation• Outside system• “Remote control”
I Intentional versus incidental interaction
