Participants filled out three questionnaires. We refer to the BASELINE as the "Base" version of the tutorial user interface, and to STIVi as the "Extended" version.  

1. Background questionnaire. Completed after signing the consent form but before getting introduced to the task and the system.

2. Post-tutorial questionnaire. Completed after testing each system configuration. 
 
3. Evaluation questionnaire. Completed after testing both system configurations.
