The ECH, or Emergency Convention Hologram, is an interactive “life sized” virtual assistant that responds to questions from users at live events.
Inspired by similar avatars seen in Star Trek, Mass Effect, and Harry Potter and built on the biological evolution model of change and complexity over time, the ECH is intended to be a charismatic, entertaining, and informative “person” there to help run a booth or panel room at conventions.
