iLiad -> Wacom -> requires pen -> not pressure-sensitive.

Thanks, much appreciated. I am not sure if I am correct, but this appears to be an E Ink panel with Wacom technology. Not the same as what PVI has announced.

If the responsiveness works out, this would open an ebook device for a lot of non-ebook stuff. For enhancing the actual reading experience, not so much for me.

Handwriting recognition can work quite well --- Evernote's RitePen is amazingly good w/ a nice interface.

It is pressure sensitive. The iLiad doesn't currently DO anything with the pressure information, but it is there.

I must admit that, for something like a bookreader, I prefer a "button driven" interface to one that involves touching the screen. I have an absolutely phobia about fingerprints on the screen - if I see a screen that's not absolutely spotless I have a compulsive urge to clean it! I'd hate to use a UI which involved pressing on the screen - I'd have to use a stylus and that would be a nuicance as far as I'm concerned. I far prefer hardware buttons.

I admit I am not 100% certain here, but I do believe that technically, the iLiad screen is not pressure sensitive. What it would require to process pressure information is a pressure sensitive stylus, which is different what PVI proposes here.

NatCh · 05-21-2008, 01:06 PM

But the hardware can support it, right? If so then it's just a software support issue. Okay, a big issue.

TadW · 05-21-2008, 01:12 PM

Well, depends on how you view it. The iLiad relies on the pressure information given by a special pen; it wouldn't work with any other object. The PVI solution discussed here doesn't need any "auxiliary" input device -- in this way the screen is fully pressure-sensitive-enabled.

NatCh · 05-21-2008, 01:21 PM

Okay, if you want to split that hair, I can go follow the logic.

It is not really splitting a hair. It is a pressure sensitive screen vs. a pressure sensitive stylus. Very different technologies to achieve similar results.

How much do we need to cram into a reading device? If the idea is to make a tablet computer out of an ereader, then a touch screen is a boon, but I am with Harry when it comes to readers: I want a clean screen and hardware buttons. I don't think there is enough margin room for me to scribble notes, so I would be better off making notes via a keyboard, as I do now on the Kindle. And writing on a screen is quite different from writing on paper: because of the smoothness the writing instrument slides a lot, something I don't like.

I love taking notes on the iLiad, and wish desperately that it had handwriting recognition as good as my Newton Messagepad 2000 had all those years ago (mostly for indexing purposes, so I could find what I've written). As far as I can tell, it's a software issue on the iLiad. I don't know of any Linux-based handwriting recognition packages at this point, free OR for sale. Switching to a "pressure-sensitive screen" instead of a "pressure-sensitive stylus" would not change that.

Capacitive touch panels are coated on top of the display, so it makes the e-paper display less attractive, it dims its contrast ratio. Also, capacitive touch panels cannot do pen input.

My understanding is that the stylus supplied with the iLiad is not pressure sensitive. However, one can use an alternate Wacom stylus on the iLiad which DOES provide pressue information, and that information is then available to software. ie the iLiad "supports" pressure information.

TadW · 05-22-2008, 05:36 AM

Harry, I hate splitting that hair (hi Nat

)), but your original question was not whether the iLiad could support pressure information (IF you had the right stylus and IF the software supported it), but how the iLiad screen differed from the PVI screen. Clearly, there is a difference, in that the iLiad would require auxiliary devices to receive this information (by itself, it knows nothing about pressure), whereas the PVI screen has the technology built-in.
