For as long as I can remember, I have carried the same picture of the future: you look at the people around you, and floating above their heads there are little icons. Status metadata, like in a video game. Single or taken. Open to talking or leave me alone. A tiny flag for the thing they are proud of this week. In my head you could always toggle it, show what you want, hide the rest, switch the whole layer off when you are not in the mood. I did not get this from one specific film. It just always seemed obvious that this is where things were going.
Then I started thinking seriously about how you would actually build it, and I hit the wall everyone hits. To see icons floating over someone’s head, something has to draw them between the world and your eyes. Smart glasses, in other words. And I already wear glasses, the corrective kind. I am not stacking a second pair on top just for this, and neither is anyone else. It is too expensive, too conspicuous, too soon. That is why this future keeps not arriving, even though the AR demos have existed for a decade.
So the honest version of the idea is to drop the floating icons, for now, and keep what they were actually for. The icons were never the point. The point was the information: a voluntary, visible-at-a-glance social status for the physical space around you. And that part does not need glasses at all.
Overhead is a small opt-in radio presence, in your phone or on a cheap clip-on tag, that broadcasts a status you chose to the people physically near you who also opted in. Not your identity, not your location history, just the little flag you decided to fly today. You check the layer on your phone, or your earbuds whisper it, or a wearable blinks softly when someone nearby matches something you care about. It is the video-game overlay, minus the part that requires strapping a screen to your face.
Market & Opportunities
The desire this taps is old and completely mainstream. You want to know something about the strangers around you before you commit to the terrifying act of talking to them. Dating is the obvious engine, the wish to know who here is single and actually open to being approached. But the same mechanic covers professional networking (conference badges are exactly this, made of paper), travelers looking for other travelers, gamers finding a fourth player in a café, or someone simply signaling “I speak French, ask me for directions.”
The technology finally matches the ambition. Every modern phone speaks Bluetooth Low Energy, the same short-range presence tech behind AirTag-style trackers, and newer phones add ultra-wideband, which knows direction and distance to within centimeters. Broadcasting a small anonymous token to a radius of a few dozen meters, and resolving it into “someone nearby is open to networking” is well inside what today’s hardware does on a coin-cell battery.
And there is a graveyard to learn from, which I consider an asset. Proximity social has been tried repeatedly (Highlight, Sonar, Color, Bump, Google Latitude, Nintendo’s StreetPass), and it keeps dying in the same three ways. It runs out of density (the app is worthless until the room has other users). It creeps people out (ambient location sharing without a clear reason). Or the hardware moment passes (StreetPass was beloved, and died with the console that carried it). This version of Overhead is designed against those three failure modes from day one, and the Next Steps below take them in order.
Key Features
- Statuses, not profiles. You broadcast at most a handful of small flags: relationship status, open-to-talk, a topic tag. No photo, no name, no bio. The mystery is the feature; Overhead starts conversations, it does not replace them.
- Opt-in at every layer. Broadcasting is off by default, per-flag, per-context. A “visible at this event only” mode makes conferences and festivals the natural on-ramp. Silence is always one tap away.
- Proximity without coordinates. The protocol answers “someone near you” and, on UWB phones, “roughly that way.” It never exposes a map pin, a distance readout precise enough to corner someone, or any trace of where you were an hour ago.
- Rotating anonymous tokens. Like modern contact-tracing protocols, your broadcast identifier changes constantly, so nobody can log your token today and recognize you tomorrow. Following a person via Overhead should be technically hard, not just forbidden.
- The phone is the display. A glanceable card list, an optional earbud whisper, an optional gentle blink on the tag when a match walks in. No glasses anywhere in the product.
- Blocklists that mean it. Block someone and your radio goes mutually invisible to theirs, permanently, at the protocol level.
Monetization
Overhead should be free and unlimited for the individual, because density is life or death and a paywall at the person level kills the network before it exists. The money is at the venue and event layer. Conferences, festivals, coworking spaces, and bars pay for an “Overhead zone,” custom event flags (“speaker,” “hiring,” “first-timer”), and aggregate, anonymous stats (how many attendees flew a networking flag tonight). Event badges are a boring, sizeable market, and this is a live badge.
The second line is the optional hardware tag itself, sold at a modest margin for people who want presence without draining their phone, kids-off-phones use cases, or venues handing them out at the door. A third, later possibility is premium personal filters (alert me only for this rare combination of flags), kept strictly on the receiving side: paying may get you better ears, never a louder voice.
Next Steps: How I’d Build It
Density first, because it kills every predecessor. Overhead should not launch as a general-purpose app into an empty world. It should launch as an event product, one conference at a time, where a thousand people in one building opt in together and the layer is instantly alive. The general city-wide version comes after the hundredth event, if it ever does.
Safety second, and it deserves plain words. A system that lets strangers see that a woman nearby is single is a stalking tool unless it is engineered not to be. That means the defaults above are non-negotiable (off by default, rotating tokens, no precise distance, protocol-level blocking), and it means red-teaming the design with the people most likely to be targeted, before launch and not after the first incident. If those protections make the product less viral, that is the correct trade and the article you are reading commits to it.
Then come the technical limits. iOS restricts background Bluetooth broadcasting, so the polished phone-only version fights the platform, which is why the cheap dedicated tag exists in the plan. And the deepest risk is not technical at all. The Google Glass lesson says the surrounding culture decides. A room where everyone knowingly opted in, at an event built for it, is the one place that lesson works in your favor. Start there.
Bonus: the dystopia I originally wanted
I owe you the ending of the original daydream. The floating icons are coming eventually, and the only question is the decade. Meta is already selling display glasses, contact-lens prototypes exist, and somewhere down the cyberpunk slope are ocular implants. The day one of those wins, a protocol like Overhead is the natural data layer for it, and my childhood picture finally renders, literally, above people’s heads.
On that day the safeguards stop being a feature and start being the whole product. In maximum-dystopia mode, the same layer shows everyone your relationship status whether you flew the flag or not, scraped from elsewhere and pinned over your head by someone else’s app. The line between the dream and the nightmare is a single word: consent, at the protocol level, from day one. If the future is going to draw things over our heads, I would rather the standard it inherits be one where every icon was put there by the person under it. That is worth building early, before the glasses decide for us.
Closing
Overhead is the social layer I always assumed the future would have, built with the hardware we hold today, and pointed at the version of that future I would actually want to live in.
If you build this, tell me. I will be at whatever event you demo it at, flying a flag that says so. And if you want help thinking through the safety model, ask. That is the part I care about most.
