Use of Large Sample Sizes and Multiple Evaluation Methods in Human-Robot Interaction Experimentation.

摘要

This paper presents details on planning and designing human studies for Human-Robot Interaction. There is a discussion of the importance of using large sample sizes to better represent the populations being investi-gated in order to have a better chance of obtaining sta-tistically significant results for small to medium effects. Coverage of the four primary methods of evaluation are presented: (1) self-assessments, (2) behavioral observa-tions, (3) psychophysiological measures, and (4) task performance metrics. The paper discusses the impor-tance of using multiple methods of evaluation in order to have reliable and accurate results and to obtain con-vergent validity. Recommendations for planning and designing a large-scale, complex human study are de-tailed as well as lessons learned from a recent study that was conducted using 128 participants, four methods of evaluation, and a high fidelity, simulated disaster site.
