> "Filter for skin colors and binary threshold"

Which skin colours? The image below that has a lot of colours that I'd associate with darker skin colours, and they're not included in the triggering zone. I'd be interested to see some data on hoe well it works with someone who has dark skin

And here we are, and the Pencil STILL doesn't work on the defectively oversized trackpads on Apple laptops. So... we're talking about more than one blunder here.

> And here we are, and the Pencil STILL doesn't work on the defectively oversized trackpads on Apple laptops. Many (including me) argue that Apple sells the best trackpads ever made, the size being a key attribute.

That and the excellent palm rejection. Probably why other manufactures didn't make track pads as large

People use their laptops under various lighting conditions. I can imagine it would be difficult (or likely impossible) to bring this PoC to a solid production level technology. It looks like a fun project though.

This project brings back memories. I worked somewhere over 20 years ago where we were working on something just like this (touch displays using cameras). The biggest challenge was definitely the lighting conditions as you mentioned. We tried to rely on natural light but it was too unreliable. Darker skin tones were harder to pick up, and then you had issues with random reflections, light and shadow being cast on the screen, etc., which would make the system detect spurious fingers and touches.

We also had algorithms to detect finger shape to detect location of the pointer and when you were touching the screen. I saw way too many videos of fingers touching screens back then, so it's funny to see similar video clips here.

"We've done tons of user testing on this, and it turns out it doesn't work. Touch surfaces don't want to be vertical. It gives great demo but after a short period of time, you start to fatigue and after an extended period of time, your arm wants to fall off. it doesn't work, it's ergonomically terrible." -Steve Jobs, 2010 https://www.businessinsider.com/steve-jobs-touch-screen-mac-...

Yea but now they're selling $400+ Magic Keyboards for iPads which then function exactly in this vertical way. No difference. I've typed this on one.

Nobody forces you to use touchscreen exclusively?

If that's the case then the interface will remain a compromise that has to work for both point and touch, and ends up being suboptimal for both. Touch input necessitates bigger hit targets, lots of additional negative space around important buttons rather than groups, and a much lower information density on anything that has a click/touch handler like a list in order to avoid accidental presses. Apps need to be writt…

The line of thinking here applies to accessibility features as well. Luckily, it is uncool to say those things against the accessibility features, and there are even many good preemptive positive arguments, such as “a good design with accessibility in mind benefits everyone”. And those same arguments do apply for touch-enabled design as well; a good design with touch input in mind can benefit all.

I wouldn't want a touchscreen MBP even if it was free, anyone else feel similar? I don't get the draw - we already optimize for keyboard commands to avoid living our fingers over to a touchpad. Why would I want to start clicking on my screen? If you're using your computer for tasks (rather than entertainment) and you're not a visual designer, I don't get why Apple are apparently going to be putting them into the new…

While I'm the same and totally agree with you, the few times I've been using touchscreen I find the habit sticks so hard that for days I keep touching my macbook screen, so there is definitely some subconscious desire for this (or I would have defaulted to using the trackpad even if my brain thought touch was available)

It is indeed addictively intuitive. Once these people get to use it for a week, they won’t ever be able to look back.

I wonder what people will say when Apple releases the touch screen MacBook later this year then.

They'll say it sucks ass, and they'll be right. Touchscreen computers have failed for a reason. Then again... so did "transparent" UI, which Apple just exhumed.

> They'll say it sucks ass, and they'll be right.

And yet my wife will disagree hard with you, as all her fingerprints on my laptop screen will attest to. She always defaults to trying to swipe the screen instead of going to the mouse.

> Touchscreen computers have failed for a reason.

The only people who think touch screens have failed are people who actually use computers, and we are a tiny minority of the population these days. The majority of people live on touchscreen devices already.

Well, when I am doing rather thinking work, so not type in commands as fast as possible - I very much do like my laptop to have a touchscreen. It is way more ergonomic and comfortable, but yes, slower. But when the real work happens in my head, I like to be rather comfortable.

(Also I can immediately test touch features of the apps I develope)
