Comparing Computer Versus Human Data Collection Methods for Public Usability Evaluations of a Tactile-Audio Display   (peer-reviewed)

We present a public usability study that provides preliminary results on the effectiveness of a universally designed system that conveys music and other sounds into tactile sensations. The system was displayed at a public science museum as part of a larger multimedia exhibit aimed at presenting a youths’ perspective on global warming and the environment. We compare two approaches to gathering user feedback about the system in a study that we conducted to assess user responses to the inclusion of a tactile display within the larger audio-visual exhibit; in one version, a human researcher administered the study and in the other version a touch screen computer was used to obtain responses. Both approaches were used to explore the public’s basic understanding of the tactile display within the context of the larger exhibit.
