I don't have a link handy, but this is what Google did when digitizing books for Google Books back in the day. They had a hardware setup that I believe had foot pedals to snap the picture, but human hands are (were?) still the best page turning technology they could muster. There was also software to make the image of the page appear flat, rather than curved as most books appear when laying open.
- sogen 6y agoyeah! I just remembered there were some news articles about hands appearing in some of the scans

- rckoepke 6y agoInteresting. I had been led to believe that Google used a linear book scanner towards the end of the big Google Books library scanning project. It looks like this may have been an internal prototype that wasn't necessarily used for large-scale scanning opert https://www.youtube.com/watch?v=4JuoOaL11bw&feature=emb_title https://www.youtube.com/watch?v=4JuoOaL11bw&feature=emb_titl... https://hackaday.com/2012/11/16/google-books-team-open-sources-their-book-scanner/ https://hackaday.com/2012/11/16/google-books-team-open-sourc... https://code.google.com/archive/p/linear-book-scanner/ https://code.google.com/archive/p/linear-book-scanner/ https://linearbookscanner.org/ https://linearbookscanner.org/
