The Zone Fan
Why sweep the whole room when two people are sitting in two spots?
🌀 Room view — drag your seats, watch the sweep
Seat (cooling zone) —
click empty floor to add, drag to move, up to 2.
Fan at the bottom —
it only swings between the angles of your seats.
Full-sweep fans cool the curtains and the hallway; a zone fan spends every swing on the people. Real units would auto-learn seat positions from motion sensors.
Why people love it
A conventional oscillating fan is a generous but gullible machine: it sweeps 90 degrees on a schedule, diligently cooling the sofa arm, the bookshelf, and the door on its way to the one person who matters. This idea makes the fan learn the room — it only oscillates between the two angles where people actually sit, spending every second of the sweep on them.
People love it for three reasons. First, it's instantly more useful: you feel the air far more of the time, because the fan isn't binging on empty corners. Second, it's quieter — fewer wasted rotations means the motor isn't swinging through pointless territory, and the air stays steady instead of gusting. Third, it's smart without being creepy: passive infrared or simple motion sensing spots the chairs people use, no cameras needed.
Set up the demo above like your own room: click two seats anywhere on the floor, crank the fan on, and you'll see the sweep hug exactly the zone between them. Add the margin slider to taste — that's the whole product.
