Goniometer for omnidirectional biophysical interface

Capturing dynamic images of the eye are not only a critical component to understanding the health of the visual system but also reveal critical biomarkers for the overall well being of the entire body.  This prototype enables the acquisition of a multi-view capture, an adaptive bionic interface for a computational approach in non-invasive rapid screening.
