I happen to use OneNote a lot recently, mainly for storing my handwritten notes thanks to the pretty accurate OCR feature.
Then I realize, there's also a great usage of OCR in OneNote other than just saving notes, it's: building an electronic index for all of your physical book.
- Step 1: Install any document scanning app on your phone
- Step 2: Scan all the index pages and table of contents in all of your books
- Step 3: Send it to whatever software you're using that has OCR feature
- Step 4: Now you can search your books digitally
For me, I use Office Lens on my phone and OneNote for OCR. But it's okay to use Scannable/Evernote, and their OCR is well enough to recognize printed texts.
OK, but why?
Every time I tried to look up something, I have to search the index page and table of contents manually. Page by page, for every book on your bookshelf, such a PITA. Are you not believe me? Let's say you have five algorithms books, and you want to find out which book as a definition about
k-d tree. Can you feel the pain?
Here's how I look it up:
Just half a second and I know I should open
The Algorithm Design Manual book, and go to page 581 to read about
And the search result is limited to just my books, not the whole internet, that's the point of scanning instead of Googling.
I feel more confident to buy more books and throw them at my bookshelf now :P
