Sweep — spatial AR without a headset

The problem

Every spatial-computing pitch of the last decade has converged on the same object: a headset, worn by one person, alone in their own field of view. That is the right shape for a solitary task and the wrong shape for almost everything a home actually needs — a recipe hovering over a counter while two people cook, a bill split visible to everyone at the table, a bedtime story projected on a wall for a kid who is not going to wear a $3,500 device. There is no product between a static smart display bolted to one spot and a headset that isolates whoever puts it on. The gap is a shared room, not a shared screen.

Why now

Pico-projector modules crossed the brightness-per-watt threshold where a battery- or mains-powered puck can throw a legible image across a real room rather than a dim rectangle on a dark wall. Depth sensing that used to require a stereo camera rig now ships in commodity phone components cheaply enough to put two or three inside a $200 unit, which is what makes a projector that tracks a room — instead of just splashing light at a fixed screen — newly buildable rather than a research demo. At the same time, screen-time fatigue has made "ambient and glanceable" a selling point rather than a compromise; people want the information, not another rectangle demanding attention.

What it is

Sweep is a single puck-shaped unit, about 100mm across, that sits on a shelf, counter or table and throws a spherical field of light around itself. Inside that field, recognized surfaces get an overlay: a countertop gets recipe steps, a table gets a bill split, a shelf gets due-date tags on borrowed books. Move the unit and the field moves with it — there is no fixed screen to walk toward. This demo is an honest 2D stand-in: a floor plan with a draggable circle standing in for the beam, because a flat page cannot demonstrate real depth-tracking or an actual lens throw. The pitch, not the demo, carries the sensing claim.

Who it's for

Households that already share a kitchen and a living room and want the overlay visible to whoever is in the room, not routed through one person's eyes: families with young kids, housemates who split chores and bills, couples who cook together. It is explicitly not for anyone whose real need is a private, personal overlay — someone doing solo focused work, or wanting information only they can see, is better served by a headset or a phone, and should not buy this instead of one. Sweep only makes sense where "everyone in the room sees it" is the feature, not a limitation.

How it makes money

Hardware margin on the unit itself, sold outright rather than subsidized, because a subsidized-hardware-plus-subscription model only works once there is a library of third-party overlays worth paying monthly for, and there isn't yet. We are deliberately not launching a subscription: the honest answer is that the first version ships with a fixed set of first-party overlays (recipes, bills, reading queue, games), and a developer-facing overlay marketplace is a second-stage bet we make only if usage shows people actually want more than the built-in set.

Go to market

Launch direct-to-consumer through a preorder campaign aimed at the ambient- computing and smart-home early-adopter crowd already active around home automation and screen-time-reduction communities, where "AR without a headset" is a specific enough claim to cut through. Ship review units to home-tech reviewers who cover projectors and smart displays, since Sweep sits in a category neither list currently has a name for, which is itself the hook. Retail placement follows only after preorder volume proves the shared- room framing lands with people who are not already spatial-computing enthusiasts.
