I just submitted v1.1 to the App Store that supports puzzles on a vertical plane so once that lands you can load up https://websudoku.com on your computer monitor to try it out! Sneak peek of that update: https://twit

Sorry about that! That was happening when the phone traveled to the other side of the scene's origin from where it started. The angle calculation got confused. I just got that fixed and submitted to Apple in v1.1 this morning. Should b

Love these ideas! I have a long list of ARKit apps I want to build.. if only there were more months in a year. I think my favorite is a Mario Kart style "ghost mode" for running. Where you could tell it what pace you wanted to go

I think that bit would be easy; but I'd probably cheat. You don't need to understand the context of the clues. You just need a big enough wordlist to brute force with. Start with the longest words since they will have the least op

Originally that was the goal. Unfortunately it wouldn't align exactly perfect (either the size was slightly off due to whether the rectangle detection snagged the inside or outside of the borders or the depth was slightly off so there

A crossword solver was what I originally set out to build. iOS11's Vision APIs for rectangle detection weren't good enough to even have a shot at it though. With better rectangle detection I think it'd be pretty doable!

Tried those first but no, they didn't work great with the data I was able to extract; those datasets are only handwritten digits which apparently weren't close enough to the computer printed ones. I think the artifacts from the sq

The parameters are not very well documented. (Or at least it wasn't when I was coding that part). But yeah I did get those set finally. Whatever I do though I can't get it to recognize any rectangles here: http://www.te

Nice! Yeah, I am using Vision's rectangle detection.. but it's really touchy. I've got a lot of heuristics in there to throw out bad results and smooth things out. It doesn't do well if there's something near the pu

Thanks for giving it a shot! Sorry it's not working for you. I'm working on a hack to get non-horizontal puzzles working right now. Unfortunately ARKit can only detect horizontal planes at this point so I'm trying to find a w

I've played with AWS Rekognition a little bit. It's definitely WAY faster to do it on-device. Plus it works even in Airplane mode. I'm running the iOS11 Vision stuff, my own text recognition CoreML neural network (81 times pe

All good; validates that I'm at least on the right track! Had to pare back my ambitions quite a bit to get _something_ finished before the iOS11 launch. I didn't expect the reception to be so enthusiastic for v1 tbh; but I guess I

Actually the solving of the puzzle itself is just done with a simple recursive algorithm. I trained a neural network to do the computer vision part to interpret the puzzles. And there are a bunch of pre-trained networks built into iOS11

It's mostly glue (but some of it is special glue). Oddly enough, digit recognition was one of the harder parts. iOS11's Vision API has character recognition but it only gives you a bounding box, it doesn't do the OCR! So fo

Hi, thanks for submitting. I'm the developer of the app! Happy to answer any questions (I was going to write up a medium post about the technical side of building the app but haven't gotten a chance yet)

Interested in hearing the opinion of any experts in differential privacy. Is it possible that a poor implementation could be worse than not using Differential Privacy at all? (My intuition would be "no".) How big of a tradeoff is
