This document summarizes a research paper on measuring perceptible affordances with eye tracking using an iGoogle case study. The paper had two supervisors and was authored by Jacques Chueke from London, UK in May 2011 for his Master's in Design. It discusses new modes of interaction using technologies like Microsoft Surface, Kinect, and eye tracking displays. It addresses the problem of hidden interactions where users do not know what actions they can take or the effects of their actions. The paper proposes studying these issues using eye tracking on iGoogle to understand how to design interfaces that make available interactions perceptible.

4. Problem Statement
• Traditional control modes of interaction (e.g. Mouse and
Keyboard) are being substituted by NUI (physical
interactions, e.g. touch, voice, gestures, eye gaze).
• Emerging Post-WIMP command vocabularies.
• Hybrid solutions of control modes (interactions) x visual
solutions (interfaces).
• The ‘hidden gestures’ issue.
• The ‘invisible’ control issue or ‘hidden interactions’.
