Over the course of the past decade the MRT (Mass Rapid Transit) stations in Taiwan have become open air art galleries: with more prominent and frequent display of various artistic creations in stations, including interactive artworks. However, unlike the audiences in more meticulously choreographed exhibition contexts, those in stations are usually involuntary. New criteria for the creation and evaluation of artworks in these context are necessary to enhance the connection between the audience and the artwork, and to elicit meaningful experience via interactivity. This research aims to uncover the critical factors that can turn an indifferent passenger into an explorative participant, subsequently leading them to obtain meaningful experiences through interaction with computer-based interactive artwork. This research focuses on artworks that are permanently installed in the stations, with three case studies conducted in MRT stations forming the backbone of the research. Field observation was the first step in each case study, conducted in order to understand the fundamentals of the interactivity between the passengers and the artworks. This was followed by in-depth interviews with the passengers and three professional interview groups. A critical Analytical Framework was formed throughout the course of the research, identifying five engaging characteristics: Incentive, Transfer, Accessibility, Play, and Challenge. These five characteristics were eventually reapplied to re-examine the case studies and the content of the interviews with the professionals. The findings of this research articulate how the Analytical Framework can be adopted in future research intended to create the conditions for more meaningful art-interactions. This Analytical Framework will assist artists, designers and researchers in their pre-planning and follow up evaluations of the degree of engagement generated by computer-based interactive artworks displayed in transport hubs. The interest that the outcomes of this research has attracted in the field suggests that the framework could be extended to the examination of various computer-based interactive artworks in similar public contexts. In this context, the framework would play a valuable role in uncovering a more dynamic paradigm used to illustrate how meaningful experiences can evolve in similar public spaces.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
