1. 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.

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.

More accurate in XY than
in Z.

Future: I will be working
on this project throughout
next year. I will continue
updating the platform. I
will test 3D scanning for
better frame models.
