LAIF: A Logging and Interaction Framework for Gaze- Based Interfaces in Virtual Entertainment Environments

Abstract

Eye tracking is a fascinating technology that is starting to be used for evaluation of and for interacting in virtual environments. Especially digital games can benefit from an integrated (i.e., evaluation and interaction) approach, harnessing eye tracking technology for analysis and interaction. Such benefits include faster development of innovative games which can be automatically evaluated in an iterative fashion. For this purpose, we present a framework that enables rapid game development and gameplay analysis within an experimental research environment. The framework presented here is extensible for different kinds of logging (e.g., psychophysiological and in-game behavioral data) and facilitates studies using eye-tracking technology in digital entertainment environments. An experimental study using gaze-only interaction in a digital game is also presented and highlights the framework’s capacity to create and evaluate novel entertainment interfaces.
