INTERFACE: Hack the Space Between is a two-day hackathon and networking event hosted by Field Lab during SF Tech Week 2026. Participants are invited to experiment with new ways to interact with technology, building experiences that respond to speech, movement, touch, vision, or brain signals, then demonstrating what they create. The event is scheduled for October 10–11 at Founders Inc., C300, Fort Mason, San Francisco. Check-in begins Saturday morning before the opening session. The event listing describes INTERFACE as part of SF Tech Week’s Hackathons and Demos programming, bringing builders together to explore and showcase novel human-computer interactions.
