Amazing how good eye tracking works on my phone (15 Pro).
Unfortunately, there seems to be no way to press buttons via blinking, only by "dwelling" on an item for a few seconds, which makes using my phone feel quite hectic and prone to to inadvertent inputs to me.
I think interfering with a biological necessity that is there to maintain eye health probably isn't a good candidate for HID input. I suspect the user would end up with very dry eyes, as they subconsciously/consciously refrained from blinking, even if it were only long blinks (which I do often if my eyes feel the need).
Now I could see a wink working! Left wink, right wink. And, with a wink, you don't lose tracking during the action (just half the signal).
I also have the Vision Pro and it’s not perfect for me. It definitely struggles with precision. Actually, now that you mention it, it felt very similar to my poor experience with the 16 pro.
It's really bad on my iPhone 13. Surprised they released it here. After one or two clicks it needs to recalibrate. There doesn't seem to be a way to not click on things either. No way to change apps. After the third recalibration, I selected "yes" to "would you like to disable eye tracking", and while eye tracking was disabled, I also lost access to swiping down on the control center or swiping up on the app switcher. Had to restart the phone to get things back to a usable place.
Just tried it on a 16 Pro Max and it’s insanely good. I really expected it to be a lot more random and buggy, but had no problem navigating the phone and “clicking” buttons etc.
This is basically the sort of “future tech” I imagined as a kid. We can now talk to computers and they talk back (ChatGPT, Apple Intelligence, etc) and flawless navigate our portable super computers just by looking at them.
It is amazing how well iOS supports these accessibility features but doesn't consider blocking video autoplay on websites, something that is incredibly distracting for people with ADHD.
Since when? Safari used to be the only ones who forced user interaction prior to autoplay. You sure you didn't manually activated a feature flag or have an extension installed?
Cursor tracks ok, but the implementation seems to replace a low-level pointing device. I.e., it's very precise and jittery - all attribution and no salience.
Also maybe like Siri it should be modal. E.g., dwell away to silence, and then dwell leading corner to say "Hey, listen..."
Holding the phone seemed to cause problems ("you're not holding it right"). Probably best with fixed positioning, e.g., attached to a screen (like a continuity camera, assuming you're lying down with a fixed head position.
Tracking needs a magnetic (gravity well?) behavior, where the pointer is drawn to UI features (and the user can retract by resisting). Salience weighting could make it quite useful.
It's possible that weighting could piggyback on existing accessibility metadata, or it might require a different application programming model.
Similarly, it would be interesting to combine it with voice input that prioritized things near where you are looking.
I'm willing to try, and eager to see how it gets integrated with other features.
I too tried this for a short while and was not impressed. However, I can’t help but wonder how ‘good’ I could get at using it if I invested more time in it. Would love to hear from someone who truly uses this tool regularly. Flying a plane is also quite cumbersome the first 15 minutes.
There are some downright neat things in the iOS accessibility options. Example: you can set it so that a triple tap on the rear of the phone turns the flashlight on/off. People think it’s witchcraft how fast I can pull the phone out and switch it on without looking down.
Either fidgeting or it just being too sensitive. I love weird right-brained UX but the problem is that I drum with my fingers all the time (the two aren't unrelated).=
I'm on Android and just wish I had a simple button (or switch) dedicated to the flashlight.
Back when I ran LineageOS it was easy to commandeer a physical button and repurpose it for this. It is still difficult to do so under stock OS? (Note I'm already using double tap of the power button to activate the camera)
Eg. It was frustrating how for the longest time Samsung wouldn't let you repurpose the Bixby button.
Thanks. Do you ever experience any 'false positives' i.e. flashlight turns on when you didn't intend? (A few other people in the comments mentioned that)
That way when a website blinds me at night because they didn't implement dark mode, I do a quick triple-tap and magic-presto, poor man's dark mode! And after I close it, another triple-tap to go back to normal.
I'm really just waiting for the OS and browser to do "fake dark mode" whenever it detects something with a white/light background. Seems like it's about time.
The physical switch on my old iPhone to toggle silent mode stopped working and sometimes it will toggle itself. I had to setup the triple tap to toggle silent mode because the alternative is like 20 clicks deep in settings.
On Android I get the flashlight by double pressing the "lock" button. It's my single most useful shortcut, my flashlight is on literally before my phone is out of my pocket.
I love how many neat and handy features are baked into the iOS accessibility settings. Apple should make more noise about these features. I recently discovered there’s a white noise generator baked in which meant I could get rid of the annoying white noise app I had been using to keep my napping baby asleep. Another recent discovery was the on screen anti-motion sickness things that move around with the accelerometer. I get terrible motion sickness and they make a massive difference.
They do mention them in their press releases, they’re featured during accessibility day and they’re occasionally in ads too. I’m not sure what more noise would be relevant for these features.
The "reduce white point" is a great hidden feature in Accessibility that dims your backlight even further for nighttime reading. You can even assign it to a triple-click or backtap (another great hidden feature).
I played around with this a bit. Doesn’t work amazing on my iPhone model (SE 3rd gen), but it’s pretty cool. I don’t think there’s an API to use it in apps yet, but I would love to make an eye controlled mobile game.
I know of at least 1! “Before your eyes” though i played it on a PC with a webcam, and I believe the mobile version is only available for Netflix subscribers, but I would strongly recommend it! It has a well told story with an very unique means of interaction
I am surprised this wasn't done much sooner, especially for "flagship" smartphones. When I was in university ~15 years ago, I met a grad student [0] who implemented impressive eye tracking software and even played WoW with it as a demo.
Fascinating reading the comments to see some people say it works flawlessly and others say it's terrible and jittery.
I'm wondering if it's lighting conditions? Bright light will allow the phone to read your eye position far more accurately than the noisy pixels in a dark room.
Or did Apple do a big upgrade to their front camera recently that accounts for the difference?
If we were to expand on face control scheme furthur, what face gestures would be used for clicking/tapping? click holding? What would be least exhausting to face muscles, what would look least ridiculous?
Double-blinking for tapping seems the most obvious. Closing your eyes for a second for tap-and-hold (and a second time to release, when necessary, e.g. for drag and drop).
I'm still of the opinion that smartphones should have page-up/page-down buttons, so that you can scroll easily with minimal finger movements while holding the phone one-handed.
I see lots of people walking and scrolling on their phone. Every once and a while they look up and continue. What will happen when you control it with your eyes and you look up, will it scroll?
It obviously can't work in all circumstances. Walking is one. Driving, whether you're controlling the phone via CarPlay or just have it mounted, is another. Using it in the dark, presumably the phone on its own doesn't light your face well enough. You can't use it with sunglasses on.
I would think this would use the attention detection stuff that’s part of Face ID and lights your face with infrared instead of just using the standard selfie camera.
When I set it up and placed it on table, I've got "bring your face into view" banner on the top of the screen.
Still, on my 13 Pro it doesn't seem to be following my eyes correctly half way thru the screen - I need to actually look a little bit up away from center of field to get pointer to select anything. I tried setting it up few times and same thing happens over and over. Scrolling seems to be done via the widget - similar to the Assistive Touch one. Unless there's some "eye gesture" I haven't figured out yet.
It's really interesting feature, surely helpful for people with mobility issues but for majority is rather a novelty you can show your friends. The feature I do use quite often is voice control which can be activated without training and it helps when you have busy or dirty hands and you don't want to touch the device
The Samsung Galaxy S4 (released eleven years ago) had some kind of eye-tracking feature that paused a video (maybe ads too) if you weren't looking at it.
Probably not. Typical eyegaze using IR has two main ways of working - bright eye or dark eye. This though wont care as much. Its based on a inference model..
How long until this is turned on silently across all devices and adtech folks, native mobile apps, and website operators are able to use your eye tracking data for A/B testing?
The selfie normalized surveillance. Social media normalized "transparency" (ie, posting every little dumb detail about yourself". Advertisements invading all aspects of life (tv, radio, streaming services, ads in your taskbar).
Apple has been pretty thorough about not allowing actual eye tracking data through to apps (just the resulting interactions), to the point that a lot of Vision devs have complained about it getting in the way of immersive UX design.
Eye tracking is very impressive technology, and foveated rendering is an excellent application, but eye control is poor UX. Yes, I'm saying the emperor has no clothes.
Imagine having a jittery cursor in the center of your vision at all times? If I had a mouse/trackpad working like that it would immediately be replaced but that's Apple's eye control. Imagine scrolling a page and every where you glance there's a spotlighted/popup control or ad? That's Apple eye control utilizing dwell and snap to item.
It's telling that the 'best window' apps/use cases for Vision Pro are video watching and Mac virtual display which has low reliance on eye control during usage. Trying to browse the web with Apple's eye control is a clear regression compared to touch/keyboard/mouse/trackpad only useful as an accessibility feature
> eye control is poor UX... a jittery cursor in the center of your vision
For a lot of folks with tremors or other mobility issues, their eyes may be much more stable than their fingers. It might be helpful to weigh the tradeoffs you're presenting with alternatives including a jittery inaccurate finger in the center of their vision, or even just not being able to use the UI at all.
> only useful as an accessibility feature
For the above reasons, that's exactly how they're marketing it

I did not suggest otherwise
> For the above reasons, that's exactly how they're marketing it
That's not how it's being received (see other HN users in this very topic) nor how Apple is marketing it for Vision Pro
If you don't need the feature, and don't like the feature, and you have to dig through accessibility settings to enable it, then it's a strong indication that the feature probably wasn't built for you
If you're curious about who this was built for, look up iPhone Switch Control [1] and you'll see how people with mobility issues otherwise use a touchscreen
Again, I understand the accessibility benefits of the feature and I'm not critiquing that. I responding to a hacker news audience mostly who want to hack this feature and I'm telling them not to bother
Vision Pro is different. It has a finger gesture to "tap".
The iPhone eye tracking mode relies on dwelling with your eyes, making it much slower than tapping, therefore not a good option for people without disabilities. Unsurprisingly, the setting to enable it is under Accessibility.
It’s not the quality of the the tracking I’m referring to. The eye tracking on Vision Pro is great for foveated rending for example. But as UI control it really doesn’t matter how good the tracking is; eye tracking is just a poor UX
You’re literally just arguing your personal opinion by continually restating your personal opinion. Some people love this UX. By definition that makes it an excellent UX for some people.
It’s not a poor UX, it’s just a poor UX for the type of user you are.

Nobody has responded to those but instead keep saying I'm attacking accessibility.
