PVI adding "touch" to eink

[athlonkmf]

Standard touchscreen functionality for new eink stuff

Leading global ePaper display vendor PVI will announce new product Touch EPD in the 2008 Society of Information Display Exhibition in Los Angeles. “Touch Reader combines innovative touch panel technology and PVI’s existing e-paper product.” says PVI Chairman and CEO Scott Liu, “By humanizing e-paper’s user interface, we expect this new product to spur demands for e-books and solidify PVI’s leadership position in the global ePaper market.”
PVI is now the leading vendor for all the available e-book products in the world. Until now none of the major e-book reader products targeting on consumer electronics marker has combined the touch technology with e-paper. One of the strengths of ePaper is that, as a reflective display, reading it does not strain the eye the way reading a traditional computer screen would. However, because e-paper emits minimal backlighting, when combined with traditional resistive touch panels (which has the light throughput of only 80 – 85%), the book becomes too dark to read. Combining capacitive touch panels is also not ideal either, as the cost is too high and stylus handwriting recognition does not work.

Does anyone know that this means:

Wacom-type touch screens, such as are used on the iLiad and on Tablet PCs, can certainly be used for handwriting recognition. Is this not what's meant by "capacitive touch panels"?

By "don't work", I assume they mean "don't work well". I've owned a couple of Tablet PCs. Handwriting recognition is something that has to work perfectly, or it isn't worth it. At first you think it does, you start to use it, and then things start to go "Point Blimfark", to borrow a phrase recently exposed here.

A few words are misinterpreted. Ah, no problem, I'll just "train" it a bit more. Then a bit more, then a bit more, before you realize you're in a Cassini fractal of irreducible error, and that you've spent so much time on this that you are thoroughly behind the curve on all those supposed productivity gains, and that you can type faster, anyway.

Then there is the "lag" factor, which you can only accommodate by retraining your brain to accept a temporal delay in the action/reaction feedback loop.

They "don't work".

It can never "work perfectly", I don't think - or at least not if your handwriting is as bad as mine. I can't read my own handwriting a week after I've written something, so I wouldn't expect a machine to be able to .

Seriously, I think that "perfection" is a rather unrealistic goal.

Oh, I don't know. I've got a tablet with Vista at work, now. Although, almost everybody is complaining about this OS - the included handwriting recognition is superb. Without any training, it recognized my terrible "spider crawlings" almost perfectly. Since I don't usually use handwriting, that "almost" didn't bother me. But, I was really surprised at the quality of recognition - it gave really a VERY low percentage of errors and you have no idea how terrible my handwriting looks (even to me - or should that be "to myself"?).
Usual disclaimers apply - not associated with MS just the usual unhappy customer ;-)

Cheers,

See what you think in a month. Note - I'm not vested in my position. I'd love to hear that it works nowadays.

I use hardwriting recognition a lot on my iPaq. It's not perfect, but it's pretty good.

I think they mean that a plastic stylus will not work with a capacitive touch panel rather than handwriting recognition itself (the assumption being that you will want to write with a plastic stylus so as not to scratch the display). The plastic stylus will work with the resistive touch panel but the light transmission is too low to use on a reflective display. If it is only 80% transmissive and the light has to pass through it twice then one third of the light is lost.

This is presumably what Astak will be using in its touch screen versions.

They are going to demonstrate the touch panel at SID International Symposium today and tomorrow. Anyone going to be there?

The zTouch 3.0 demo unit -- as well as a 15" point-of-sale device -- will be on display at the SID International Symposium, Seminar and Exhibition from May 20-22 at the Los Angeles Convention Center. F-Origin and PVI will be exhibiting the zTouch 3.0 demo unit at booth number 627 on the showroom floor. In addition, Scott Liu will be speaking at the Exhibitor Forum to explain the details and benefits of the F-Origin solution for PVI's ePaper displays. The forum, titled "A Human Interface for eReader -- PVI's Innovation in Making eReader more User Friendly," will take place in West Exhibit Hall B at 12:00 PM on May 20th.

Yes, I saw it in person. The touch screen is awesome!

In what way does it differ from the iLiad's touch screen?
