Smart homes' real value lies in how devices connect and work together, not just individual control. But current systems depend on smartphone apps, lack spatial context, and make automation setup feel like programming. We wanted to solve this disconnect by bringing device control into physical space using AR.
Three principles guided our design: intuitive linking without code, a spatially-aware interface where you interact with devices where they actually are, and reduced cognitive load so you just follow what you see.
We chose eye-gaze for pointing over raycasting since it covers a wider and faster range. Selection uses a grab gesture that doesn't overlap with casual hand movements. Disconnection requires a two-handed cut to prevent accidental deletion.
