Enhancing user experience through an HCI research tool. Case study: Cognitive urban planning platform (PUC)

Abstract:

There is no doubt that the way people interact with computers has changed dramatically over the last decade. Human-Computer Interaction (HCI) plays an intricate role in the communication forms in a digitized and globalized world. HCI's research tools, such as eye-tracker, allow analyzing user experience and measures where people are looking and how long it is influenced by cognitive processes beyond attention, such as perception, memory, language. This paper scientifically explains how eye tracker technologies can record what people register with their eyes and describes how user interface design can benefit the user experience to enhancing citizens interactions in urban informatics environments. Early outcomes have shown that the eye-tracker allows obtaining heat maps representing the areas of interest and fixations; this analysis enabled improving the Cognitive Urban Planning platform (PUC by its initials in Spanish), placing each AOI (area of interest) in the proper location, thanks to it, some recommendations have been obtained to improve the PUC user interface for connecting to citizens.
