REUMass Amherst 2015: A Summer Research Experience in Data Science The iShadow Platform: Reproducibility Connor Pope ECE Background: The iShadow project is about designing a wearable, real-time gaze-tracker [1]. [2]. Problem Statement: Redesigning the instrumentation so as to enable reproducibility. Impact: This allows other research groups to use the iShadow easily, and allows for rapid prototyping and testing. Prof. Ganesan and A. Mayberry College of Information and Computer Sciences University of Massachusetts Amherst University of Massachusetts Amherst Introduction Results Conclusions References The new platform is based on the ‘Romco-5A’ military frame. I used AutoCAD to design a 3D model of the frame and peripheral parts. I used a Formiga P110 3D printer to print multiple variations of each frame w/parts. I tested each variation and updated my models accordingly. Iterate until satisfied. I also dimension tested the 3D printer to test its resolution in the XY-Plane and Z-Plane. Discussion: The designed frames are extremely close to the dimensions of the R5A frames. Peripheral parts and their angles have been tested, and we gained valuable insight into what angles work.

I will test 3D scanning for better frame models. Approach The iShadow Eye Pictures from Testing Peripheral Parts Variations of Frame
