I'm very interested in eye-tracking and see a lot of potential in this tech.

For inspiration, check out the Vocal Eyes Becker Communication System: https://jasonbecker.com/archive/eye_communication.html

A system invented for ALS patient Jason Becker by his dad: https://www.youtube.com/watch?v=wGFDWTC8B8g

Also already mentioned in here, EyeWriter ( https://en.wikipedia.org/wiki/EyeWriter ) and Dasher ( https://en.wikipedia.org/wiki/Dasher_(software) ) are two interesting projects to look into.

So, guy who has deployed eye-scanning machines all over Africa and has found that many of them have been hacked and are giving incorrect responses suddenly has a friend with ALS and is willing to fund better quality eye tracking? Either: - Part of the whole world-coin thing was privately trying to get the data to help his friend - He doesn't want to say "looking to develop eye tracking tech for my world-coin scam", s…

I believe you may be mixing up Paul Graham and Sam Altman. Easy to do because they both ran YC at different times, but WorldCoin is from Sam Altman and this tweet is from PG.

Indeed, I got confused!

Although I still wonder, since the two run YC together.

Thank you for correcting me.

Edit: Check out Dasher for a much better interface to enter text with a cursor, compared to a virtual keyboard. https://dasher.acecentre.net/ , source at https://github.com/dasher-project/dasher --- I remember seeing a program years ago, which used the mouse cursor in a really neat way to enter text. Seems like it would be far better than clicking on keys of a virtual keyboard, but I can't remember the name of this p…

That sounds like Dasher ( https://dasher.acecentre.net/about/ ), invented by the late David MacKay.

Nice. Random thought:

Geometrically 50% of the movement does nothing (going left is a null action). In terms of distance moved by the pointer it would be more efficient to arrange the options as a circle around the pointer, with maybe the bottom 10% of the circle used for the null action

A possible benefit is 90% of the screen could then be used to display a larger set of options, which could let the user bisect their choices more quickly

There is a Turkish ALS patient, he has a youtube channel, he is creating youtube videos, podcasts, streams on twitch thanks to eye tracker.

He is using tobii eye tracker. There is a video he made about the eye tracker. It's in Turkish but you can see how he uses it.

Here is a article about him in English: https://www.dexerto.com/entertainment/twitch-streamer-with-a...

I worked on eye tracking hardware for Microsoft HoloLens. Several AR headsets offer decent eye tracking, including Hololens 2 and Magic Leap's ML2. I think Tobii's eye tracking glasses are probably better as a stand-alone solution though: https://www.tobii.com/products/eye-trackers/wearables/tobii-...

How much do Tobii glasses cost?

I don’t know about the Tobii glasses, but I have a Tobii head/eye tracker that attaches to my monitor, and it works incredibly well and was only $200 or so. I’d be surprised if this isn’t an essentially solved problem at this point.

Sam Altman hasn't been affiliated with YC for a while now.

My three partners and I have be developing and selling multi-camera arrays specifically for eye tracking as well as measuring other physiological features for several years now. Our main customers are a couple university research groups, a human factors group in Lockheed, and just recently the US Air Force. In fact we just returned from a trip to Wright-Patterson installing an array in a hypobaric chamber to perform…

How expensive is your system? Do you have software that converts internal tracking info into pixel coordinates? Multiple screens?

Luxury car prices per array due to development, customization and the type of clientele. We have a mech engineer onsite to adapt the camera arrays to the environment, such as a cockpit or centrifuge, while taking into account the field of views and mounts. Yes it can handle multiple screens and curves like domes, the fun part is working out the geometry to convert gaze vectors into pixel coordinates. Pixel accuracy is a function of the number of camera (6 to 12), distance to the array, and geometry of the subject and array but we can typically discern which button / control / digit a pilot observed.

Of course cost can be substantially decreased if everything was standardized and the mech engineering was done once. BOMs (excluding the high-end desktop computer) is about $2000-$3000. My dream would be to reduce that cost by moving the computer vision to compute modules per pairs of cameras reducing the BOM to < $1000 and avoiding the desktop.

This thread is about eye tracking. You went from talking about the congo for some reason to now shifting to "lithium takes a lot of water". But I won't buy a SUV that weighs 2 tons to sit alone in it most of the time and have it parked 95% of the time in a garage. What are you even talking about? This whole thread is about eye tracking. We should strive to be sober, to buy repairable goods whenever possible, to educa…

It's all related. High tech has a lot of negative impacts which are rarely if ever evaluated and more importantly compensated. The reason is they bring in money. The entire supply chain and lifecycle of a product should be evaluated to understand if it is a net positive or a net negative. Not only the finished product: "wow eye tracking how cool let's deploy everywhere regardless of how the materials for that tech ar…

To be clear, in your mind when someone talks about wanting to fund certain types of software, it is someone's duty to talk about lithium batteries using lots of water?

Naive question from someone not in the field but is there any solution out there that does not use IR + dark pupil segmentation?

Seems like all the solutions out there are some flavour or variation of this.
