       Show HN: Eyesite - Experimental website combining computer vision
       and web design
        
       I wanted Apple Vision Pros, but I don't have $3,500 in my back
       pocket. So I made Apple Vision Pros at home.  This was just a fun
       little project I made. Currently, the website doesn't work on
       screens less than 1200x728 (Sorry mobile users!) It also might
       struggle on lower end devices.  For best results, have a webcam
       pointing right at you. I tested my website with a MacBook camera.
       Any comments, questions, or suggestions are greatly appreciated!

           | Just to play devil's advocate here... I'm about as extreme a

           | I don't consider tracking on digital billboards to be
           | inherently evil. It _could_ be used for evil (like - an
           | authoritarian government tracking who looks at a billboard
           | for an opposition political leader, for instance). But it
           | could just be innocent data gathering. If you ran a plumbing
           | business and paid $10k for a billboard, wouldn 't you want to
           | know if it was worth it or not? It's not as if decades of
           | focus groups and hand-wavey feelings about what is or isn't
           | effective advertising didn't already steer us into a society
           | entirely dominated by big loud ads everywhere.
           | 
           | People who make products and sell services need to advertise.
           | They in turn pay taxes. The many layers of parasitism in the
           | advertising world historically relied on conning these people
           | and taking their money in exchange for an unprovable
           | proposition, namely that if you run this ad we tell you to
           | run, right here, your sales will go up - but we'll never be
           | able to actually tell you for sure by how much, or whether it
           | was a good deal for you. From that perspective, more and
           | better viewership data helps undermine the advertising
           | bullshit machine and close the gap between people who run
           | businesses and the people they're trying to sell their
           | services to.

       | Ha! The timing is impeccable. This is a great demo. I've been

       | Nice to see people getting interested in eye gaze. There are two
       | things that you might like to look at that can help the UX.
       | 
       | 1 - Calibration. Looking at static dots is BORING. The best idea
       | I've seen is Tobii's gaming calibration where you look at dots to
       | make them wobble and pop. This makes the whole process feel like
       | a game, even when you've done it a hundred times before. I would
       | love to see more ideas in this space to give a much more natural-
       | feeling calibration process - even better if you can improve the
       | calibration over time with a feedback loop, when users interact
       | with an element.
       | 
       | 2 - Gaze feedback. You are absolutely right that seeing a small,
       | inaccurate and jumpy dot does more harm than good. Again, Tobii
       | have led the way with their 'ghost overlay' for streamers.
       | 
       | For an example, see the following video. After calibration the
       | ghost overlay is used to give approximate feedback. This is
       | enough that some naive users are able to make small adjustments
       | to a constant calibration error, or at least give feedback that
       | the gaze is wrong, not that the UI is not responding.

         | 
         | 1 - I experimented with some calibration involving staring at a
         | point, but I found it troublesome as blinking would make lead
         | to some inaccurate calibration data (webgazer doesn't have
         | blink detection). It was also a little more fatiguing since the
         | user would have to really focus on staring the entire time. I
         | found that it was less mentally fatiguing if the user could
         | control their own calibration give themselves room to blink or
         | just rest their eyes for a second.
         | 
         | 2 - Ghost overlays is a really good idea. I'll see what I can
         | do to implement that feature.
         | 
         | I really appreciate you taking your time to write this!

         | I have been experimenting with using 5 phases of movements with
         | each phase covering different areas of the screen while being
         | actively moving. The last phase makes the dot move in a
         | Lissajous-like motion which is more fluid like you are
         | suggesting.
         | 
         | The challenge is recording and syncing the motion at a higher
         | frequency and being able to save without much drift and the
         | performance of these landmark/gaze models is often slow.
         | 
         | One more option to speed it up is not to do the eye tracking at
         | record time, just record a crop video of the face and the
         | screen first at 60Hz and then run the model on each frame and
         | update the metadata of the dataset.

         | Thanks for your interest! An eye tracking game is an

         | of overhead used for eye tracking that an entire game on top of
         | that would be too laggy to be playable. Also, the eye tracking
         | software right now doesn't seem precise enough for things like
         | aiming. I could totally see a pure standalone game that
         | utilizes eye tracking.
