## Brief In the future, when everyone has AR glasses. Vendors and app developers will want to keep track of where you looked, at what time, and at what focal distance. If we’re placing things in a shared universe or in [[meatverse]] advertisers, meta-investors, and content creators will want to know how many eyeballs they’re getting and if the right people are seeing them. LookDB becomes part adexchange and part data broker for the metaverse and meatverse. ## History I came up with this idea half a page into [[SuperSight]] > Imagine this: you are strolling down Lafayette Street in New York on a gloomy December morning, wearing your new augmented glasses. Thanks to the tiny data projector and optical combiner in these stylish spectacles, virtual and real are nearly indistinguishable. A holographic digital layer blends and "sticks" to the world as you move your head. And this new way of seeing is tailored just for you. The person walking next to you has a different curated projection. The first thing you notice is how much richer and saturated with informa- tion the world has become. As you look up, the skyline includes translucent future buildings, some still in a sketch style to invite your feedback for the next zoning meeting, others rendered with detailed materials and flagged with their estimated completion date. Better not stare up at those high-rise residences too long or you'll start getting ads for their units, with their panoramic views, pro jected into your current apartment's windows. So you look down. A widened sidewalk and cycling lane are superimposed on the street to show a redesign coming in a few months, with a graph project- ing a drop in bike accidents. Following your system preferences, highly rated family-owned restaurants float huge, recommended dishes across your path. Here comes tortellini from the right; now a sushi boat from your left; and dead ahead, a steaming bowl of projected ramen--that's worth a quick stop. The second, more problematic thing you notice is that these augmentations aren't neutral. They appear optimized to stimulate your particular brain and are biased toward positivity (or was that a configuration preference, too?). Your Al "reality editor" infers that you don't want to see the trash cans it detects lining the street this morning, so it replaces them with virtual bushes and trees trans- planted from your childhood front yard. New York City never looked so good! (If only there were a search-and-replace for smells…) And because the glasses
