Experimental Design for Human-Robot Interaction with Assistive Technology

چکیده
Experimental design for human subject research must consider many factors. Who is the end-user? Is this population accessible for user testing? How many conditions will be tested? How many participants are needed? What types of data can be collected? How should the data be analyzed? This paper surveys experiments conducted in human-robot interaction (HRI), assistive technology (AT), and humanrobot interaction with assisitve technology (HRI-AT). To illustrate complexities in experimental design in HRI-AT, we present a case study of our two experiments – a preliminary user trial with able-bodied subjects, and a recreation of the first experiment modified for cognitively impaired wheelchair users. Also, we discuss important points learned while conducting an evaluation with cognitively impaired wheelchair patients.
