Projects
XR-COP
DEVCOM Army Research Labs
A virtual reality command and control application for the Army which supports distributed collaboration using 3D terrain maps. I've supported developing, evaluating, and conducting field test of the XR-COP with soldiers out in the field.

Eye-Gaze AR Information Mediation
DEVCOM Army Research Labs & UT Austin
A collaboration between ARL and UT Austin. We constructed an AR system and ran a study showing how eye-gaze in Augmented Reality (AR) can help reduce cognitive burden by hiding unnecessary information in a congested environment.

Fuse
Carnegie Mellon HCII
Based on my thesis work, Fuse allows users to manage, and compile their messy browser tabs in to a structured workspace. It's available now as Skeema, a chrome extension from my collaborators at CMU.
- React
- Web Extension
Meta
Carnegie Mellon HCII
A core part of my thesis work, Meta is a tool that allows users to extract and compare entities (in this case products) across websites. From a search, it would collate the most recommended products from a variety of sources into a single view. See more in my linked thesis.
