    Development and Usability Evaluation of an E-learning Application Using Eye-tracking
    (2012-07-16) Deotale, Punit Ashok
    The primary goal of this research is to use eye-tracking in the development and usability evaluation of an e-learning tool called "Problem Solving Environment for Continuous Process Design" (PSE). The PSE is meant to aid engineering students in learning the design processes of automated manufacturing systems. PSE is a user-interactive Flash application which gives the user an opportunity to virtually design an automated industrial process by manipulating the parameters associated with it. PSE is evaluated using eye-tracking experiments in which users' eye movements are tracked using camera and sensors to determine users' gaze direction and fixations. The data collected from the experiment is used to determine if use of visual cues improved the usability of the PSE. Results show that use of visual cues for gaze direction improved the usability of the PSE application, based on faster task completion times and improved navigability.

    When pigs fly: a study of computer generated paper folding
    (2009-05-15) Nitsch, Elizabeth Jeanette
    The purpose of this thesis is to develop a system for folding an origami model using computer generated, or virtual, paper. This research is detailed according to both the creative and technical aspects of that process, with particular attention given to formulating a solution for animating the paper in a way that is physically realistic. The project is executed in Autodesk Maya, a 3D computer graphics program, and rendered with mental ray, a production quality rendering software. The final results are illustrated via excerpts from When Pigs Fly?, an original 3D short which uses the developed methodology to give life to an origami-based narrative. The techniques employed in this thesis can provide a valuable framework for other artists embarking on similar productions and supply a foundation for more advanced problems related to folding and computer graphics.
