Experiment Design

This week, I hope to write my own usability study, similar to the study in "Interactions and Training with Unmanned Systems and the Nintendo Wiimote". Here are some of the basic ideas/changes I would implement:

-The obstacle course would involve tasks like moving blocks from place to place, and steering around specially marked areas.
-The participants would still receive training, and then perform the obstacle course 3 times per control scheme.
-Participants would navigate the robot through the obstacle course using 2 (rather than 3) control schemes: iPhone and "controller" (some sort of standard controls for the specific type of robot being driven).
-The questionnaire would include the following questions (5-level Likert scale):

1. Instructions on how to perform gestures were clear

2. Gestures were easy to learn

3. Gestures were easy to remember/recall

4. Gestures were easy to perform

5. The Gestures performed did not cause my hands, arms, shoulders and/or wrists to become fatigued

6. The iPhone was easy to hold and use

7. The system recognized the gestures accurately

8. Controlling the vehicle through gestures was easy

9. Controlling the vehicle through the iPhone was easy

10. Controlling the vehicle through the "controller" was easy

The study will be very similar to the one from the paper. Eventually, there will be more detailed outlines of the study's procedures. Stay tuned, and as always, any suggestions are welcome!
