  Usability engineering and usability testing are concepts that continue to
evolve. Interesting research studies and new ideas come up every now and then.
This paper tests the hypothesis of using an EDA based physiological
measurements as a usability testing tool by considering three measures which
are observers opinions, self reported data and EDA based physiological sensor
data. These data were analyzed comparatively and statistically. It concludes by
discussing the findings that has been obtained from those subjective and
objective measures, which partially supports the hypothesis.
