Re: ReMarkable 2.0 – A digital notebook that feels like paper

I recently bought the ReMarkable 1 (wasn't willing to wait for preorder on the 2, and the differences don't look that significant). I kinda love it: I'm a professor, and 99% of my use is in reading article PDFs---it's a vastly better experience than reading on an eyestrain-inducing glossy screens or printing off. One major annoyance, though, is that it's clunky to switch between documents---I like to take notes in a…

For a better PDF experience, you might want to try 'koreader'. The native PDF support on my Kobo Forma was so bad I was ready to return it, before finding this. It's an open source PDF/epub reader that you can install on Remarkable and other eInk readers. It's just an app - it doesn't replace or degrade any existing functionality.

Is this written by a lobbyist?

Blue light causes cataracts if nothing else. It also affects sleep cycles which can cause fatigue and all sorts of strain on the eye and body.

But “ Does this blue-light pose any hazard to our eyes?

Nope, not to my knowledge”

Animations are not perfectly smooth causing strain on scrolling (I can see the unevenness even on my 11 pro with every scroll). Colors are constructed - ever look at a phone on acid? This also can cause subconscious strain.

The article also fails to recognize that most eink displayed are in fact illuminated.

The bottom line is reading on eink is relaxing in ways a tablet is not.

Remarkable haven't yet delivered the 2.0 device. Let's first see when it appears on the market. I has been delayed twice so far. So far it's in "pre-order" mode.

They have had two delays so far, and both of them were announced literally days before the "expected" shipping deadline. They are checking many checkboxes on my "likely vaporware" checklist.

The only thing they have in their favor is that they shipped v1 succesfully.

But no mention and video evidence of the pen input lag and precision, which is what's supposed to set this apart from other eink display solutions. The 1 has some lag, just enough to still be a nuisance: did the 2 fix that?

I have the 2 right here and it's better than the first. There's still a perceptible lag (that is, it isn't imperceptible) but it's better than anything else out there including other eink devices (I also have a Boox here that I compared it to, and the Sony DPT before it).

Just to confirm, when you say, "better than anything else out there," that includes the latest generation of iPad Pro with Apple Pencil 2, correct?

Earlier quoted context omitted.

You would definitely notice a 21ms lag while writing. Ideally you want to get below 10ms, but for physical-object-like responsiveness 1ms is the standard. See this old video from Microsoft research which demonstrates https://www.youtube.com/watch?v=vOvQCPLkPt4

I just watched the video and maybe I missed it but doesn't that mean that in order to have 1ms latency you'd have to have a screen refresh rate of 1000 frames per second? That seems like it would cause serious cost increases for displays, controllers, and graphics cards.

If it helps, you just have to refresh the (very small number of) pixels under pressure, and only at such a high right for a brief moment while they are being pressed.

I wonder if you could have a separate layer which physically (chemically) responded to the pressure to make it look like the screen was drawing your line, but which only lasted for about 50ms after the pressure is removed.

This chemical layer would be visible for just enough time for the real eInk pixels to actually refresh underneath the "pressure mask".

I have been very happy with my ReMarkable 1, and have ordered the ReMarkable 2.0. Hacker News might be interested in the active development community around the device: https://github.com/reHackable/awesome-reMarkable The device is open. It's just an embedded linux device. You can ssh into it, and run arbitrary code. The SDK is based on Qt. You can also connect a keyboard to it over a USB-on-the-go port. I have been…

Do you use the text OCR feature? Is that component opensource?

It seems not, unless the server code is hiding somewhere publically.
