The dataset includes 9,448 question-and-answer pairs, each requiring a model to identify a specific moment in an ongoing video feed rather than scrub through a finished file. That distinction matters: most existing benchmarks hand a model the entire video upfront, which is nothing like how a wearable device actually works. S-EMBER forces models to operate causally, recalling only what has already streamed past.\n\nThe benchmark surfaces what the researchers call a localization paradox. Scaling up model size, resolution, or frame sampling rate improves semantic reasoning - the ability to describe or summarize events - but does nothing meaningful for temporal grounding, the ability to say \"that happened at 2:14 PM, not 2:22 PM.\" That gap is architectural, not a matter of throwing more compute at the problem. For anyone building wearable AI assistants that need to answer questions like \"where did I leave my keys this morning,\" this is the specific capability that remains broken.\n\nThe field has been racing to build always-on AI companions tied to smart glasses and similar hardware, with Meta, Google, and a handful of startups all placing bets. S-EMBER is a useful corrective: it sets a hardware-authentic baseline and makes clear that the retrieval problem is not close to solved.","[\"ai\",\"wearables\",\"benchmarks\",\"research\"]","2026-07-07T04:00:00.000Z","2026-07-07T07:39:19.923Z","2026-07-07T07:39:22.797Z","published",null,[],"ai",[24,26,27,28],"wearables","benchmarks","research",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.02689",0,{"sections":35},[36,40,45,50,55,60,65,70,75,79,84,88,93,98],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":18},"Dev Tools","dev-tools",59,{"name":80,"slug":81,"count":82,"latest_published_at":83},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":85,"slug":86,"count":82,"latest_published_at":87},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
