Adds eye tracking calibration using linear affine transform
- Adds 3 corner calibration (top left of screen, top right, bottom left)
- Adds logging for calibration
- Creates affine transform to shift the tracked coordinates to a more accurate place.
How to use (potential readme.md):
- Look at top left of screen
- Press "TL" under calibrate
- Repeat with top right, bottom left
- Press "Translate"
Nice approach! However I am not able to move the cursor to the bottom right corner after calibrating. It just gets stuck in the middle.
I'll take a look at it again, assuming top left corner is set correctly the affine transform should be correct. It works on my phone, and if the cursor is moving in other parts of the screen then it's difficult to see why the bottom right is not working.
Maybe it's because I'm using it on the iPad Pro. I changed the screen size constants so far, but maybe something is wrong with that. Or it doesn't scale so easy on bigger screens like expected. :(
That’s probably why. It works fine here but I will want to test it on the iPad Pro and create a separate PR for that.
I find the results to be similar, only that Hawkeye has a larger smoothing. Calibration should be much easier if dots are presented on the screen for sure.
@RolandColored want to understand why the matrix multiplication happened in such order? Any docs I can read to understand this in depth.
Hi,
I love the improvement requested and implemented by Schemetrical but the precission is not so good as I want. Do you have done any more improvements? I'm really interested. Thanks in advance!
