  • Right, I have a 1600p laptop screen as well and the resolution downgrade was noticeable. What you say about the projection makes sense, unfortunately I haven’t seen any specs for the micro OLED displays they use, they only claim that the virtual screen has 1080p, which might be achievable if the displays DO in fact have a higher vertical resolution. It DOES appear that they’ve increased the size of the displays from 0.55" to 0.68" but there’s no information on the native resolution that I can find.

    If I saw these glasses in a store somewhere I’d probably try them out but they’d have to be VASTLY better than the ones I tried to convince me to buy them.


  • I tried a previous incarnation of these and was not impressed. The screen was too dark in bright rooms and the resolution and image sharpness was lacking. Also the response time was rather slow, which made them basically unusable for playing games or watching (which was primarily what I bought them for). Additionally, the virtual screen was not fixed in space but moved around when you moved your head, which gave me vertigo after prolonged use. I ended up returning them after a week.

    It appears as if these are at least the second, if not third generation (mine were simply called Air), and the spatial processing chip might help alleviate some of these issues, but I’m disappointed to see that the vertical resolution has not been increased. But at 32:9, it seems that these have twice the horizontal resolution, which would equal two 16:9 screens next to each other.

    I wonder if these might be worth giving another try, but I’m loathe to risk it as my Amazon account has been flagged for returning too many purchases before.













  • I’m sure there are many ways to improve on this solution, but they would all require significantly more effort (ElasticSearch isn’t exactly trivial to set up).

    This is really just a proof of concept, the most minimal viable implementation that gets you something similar in terms of functionality.

    For instance, Windows Recall stores OCR content tagged by app, this solution doesn’t. Also, as others have mentioned, a practical implementation should likely check if anything has changed at all and discard any screenshots that don’t have any new data.


  • It appears to be as simple as tesseract <infile> <outfile>. Possibly could even pipe (or tee) the screenshot straight into that and save both an image and a text file in a single command line.

    So something like this should do the trick:

    gnome-screenshot -f - | tee /Microsoft/yourPrivacy/$(date +%s).png | tesseract - /Microsoft/yourPrivacy/$(date +%s).txt
    

    Skip the database, just use grep to search that directory if you need to find anything. Voilà, homemade Recall.




  • In order to be certified for running Recall, machines currently must have an NPU (Neural Processing Unit, basically an AI coprocessor). I assume that is what makes it practical to do by offloading the required computation from the CPU.

    Apparently it IS possible to circumvent that requirement using a hack, which is what some of the researchers reporting on it have done, but I haven’t read any reports on how that affects CPU usage in practice.
