Question Improvement

[bboudaoud-nv]

The current per-session question system in FPSci is functional, but leaves much to be desired in clarity of configuration and flexibility. There are a number of things we could improve around this functionality including:

• Allowing questions to be presented on a per-trial basis in addition to per-session
• Improve configuration
  • The difference between MultipleChoice and Rating questions is unintuitive (multirow vs single row button layout)
    • When using MultipleChoice the number of buttons per row is fixed, this could be made programmable
  • The randomOrder parameter defaults to true for all types of questions (unintuitive especially for Rating)
  • We could support a drop-down style question in the future

Suggested immediate changes include:

• Make randomOrder default to false when the question type is "Rating"
• Add a buttonsPerRow that defaults to 3 for MultipleChoice and the length of the options array for Rating
• Consider uniting MultipleChoice and Rating questions given the availability of buttonsPerRow option above (this parameter would always default to the length of the options array)

Longer term changes include:

• Add support for per-trial questions (and logging these results affiliated with the trial)
• Add support for drop-down questions
• Add support for multi-line entries in the options array (likely using a \n character)
