This comment makes me think we’ve gone too far and I should shut off my phone.

#113I 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-...
Have used Tobii as well and they are very accurate with a bit of calibration.

#114Yes, the ALS/disability angle is noble. Viewed another way, the entire human race is afflicted by the disability of not having access to eye-tracking (and other) technologies. Paul Graham and co. are also invested in companies that are going to be highly enabled and boosted by the growth of eye-tracking and related technologies. I don't view his statement of motivation related to ALS as insincere, I just also notice that it's accessible, easily understandable, and also in line with other aspects of Paul's motivation (and that's a good thing).
I would also recommend Jean-Dominique Bauby's Le Scaphandre et le Papillon to anyone interested in this topic. Typing using eye movements was used in that book in a slow, inefficient manner. In the book's case, the question one should ask is, was his UI paced at the exact correct speed? I was and still am deeply emotionally moved by what the author was able to accomplish and convey. I am unsure if a faster keyboard would have made a meaningful and positive difference in that particular case, to the author's quality of life. I'll need to give that book another read with that question in mind.
Happily, I expect eye tracking to find fascinating, novel and unexpected applications. As others have stated, UI/UX design is an interesting part of this puzzle. For example, if you ask an LLM to output short branches of text and have a writer look at the words that he wants to convey. It's definitely blurring the line between reading and writing. Myself, finding writing to be a tactile exercise, I think that emotional state comes into play. That's what I'm interested in. Yes, can you literally read someone's eyes and tell what they are thinking?

#115Jason Becker is a great subject because if you can help him compose with his eyes the world can use his music he’s a genius.

#116EEG recording is an alternative that would outlast the potential disease-related degradation of eye movements. Manny Donchin gave a brown bag at UIUC about the possibilities of using this approach to support communication by ALS patients many years ago. It's clever: they use the P300 marker to index attention/intention. I do not recall whether he and his colleagues ever commercialized the tech. I believe that this pu…
I did a PhD in brain-computer interfaces, including EEG and implanted electrodes. BCI research to a big extent focuses on helping paralyzed individuals regain communication. Unfortunately, EEG (including P300) doesn’t provide sufficient signal-to-noise ratio to support good communication speeds outside of the lab with Faraday cages and days/weeks of de-noising including removing eye-movement artifacts in the recordin…
+1 from a fellow BCI PhD. EEG tech is not ready for this application yet.

Agreed, the eye tracking itself is really a mostly-solved problem (Tobii are indeed leaders in the area). It's how it's used that matters - and as mentioned above, it's likely that it's the usability/interface that needs work.

#118This seems like it would fit https://thinksmartbox.com/products/eye-gaze/ I once interviewed at this company. Unfortunately didn't get the job but very impressed nonetheless.
I was part of developing the Lumin-i variant of this (working for Smart Eye)! Working with the Smartbox team was a pleasure :).
The solution actually works pretty well, especially when calibrated to a single individual.

#119Solving eye-tracking keyboards is not so much a task for a company with eye-tracking expertise but for one with expertise in large language models.

Please elaborate.
