IRBs and Questionnaires

This week was dedicated to filling out IRB forms and working on the questionnaire that will be given after the experiment. This marks the beginning of the serious thinking about experiment design. I decided that every subject should perform the obstacle course three times: once with on-screen controls, once with tilt-based controls, and once with hand gestures.

The questionnaire aims to explain why subjects performed the way they did during the study. There is a short section about video game fluency, especially console games, to figure out which subjects are gamers and which are not. Most of the questions will be changed to 5-level Likert scale questions and the questionnaire will be put online via SurveyMonkey or Google Docs (link to come).

In terms of the system itself, I purchased an arm band for the experiments, and will hopefully try it out over the next week. My hope is that being able to attach the phone in some way to the subject will reduce the awkwardness of handling the controls, since the phone is very large/flat.

The hand gesture based controls are not complete, but it is more important to decide on which gestures will be used. Many of them will probably be pulled from the 1987 Army Visual Signals Field Manual.
