MS Research had a neat demo on this very topic some time ago.
Edit: never mind, it seems they use their own hardware. In that case, it would be interesting to know if iOS allows fast raw access to the external periphery.
My use case is simple, I just want a digital copy of my notes -- I don't need any OCR or anything fancy like that, and I'm not convinced that a LiveScribe is the way to go.
I had high hopes for the NoteSlate, but that product has turned out to be vapor ware.
The laggy footage starting at 0:28 looks like real-time to me. You can see the crosshair falling behind at 0:35 too, and that's clearly normal speed unless the guy can do handwriting in slow-motion. And I can't think of any way a high framerate would affect the perception of lag when played in realtime.
Come to think of it, I'd rather use an android with a custom ROM that turned it into dedicated writing/drawing device.
Edit: watching this video also made me think of how much better math textbooks could be on dedicated writing tablets.
I'm going back to school to finish up a math degree, so I've recently been reading a lot of math textbooks. An interactive version on a dedicated tablet would be amazing.
Think about it--animated examples, working out problems right there on the page, writing a function and then tapping it to automatically graph it.
My Wacom penabled tablet/laptop convertible PC was invaluable at taking calculus and economics notes in Word 2007 - You can type all the text, then pick up the stylus and draw formulas, graphs, and symbols where you want.
It was such a powerful use-case for me that I don't understand why nobody has copied it yet.
Admittedly, graphs and illustrations were an issue. In fact, I basically didn't bother with either. But just for text and math notation, LaTeX was awesome.
Who knew, the world is indeed bigger than the US of A. I'm guessing you knew that before you posted such nasty stuff when you clicked on Nav's Linkedin page and saw that his degree was from Manukau Institue of Technology MIT NZ.
Costic & Willfully Dumb in one post - Jetman, please fly far, far away.
Nav earn't his degree, is working a full time job + doing about 35 hours a week on Collusion. We're busting our asses to build some very cool tech, and do care about our rep.
Frankly we're kind of stunned at the generally negative attitude on Y Combinator hacker news. We're in the same boat (startup), starved for our art for the last year, we built it, and were going to market. Give us a break. More so - give us your support.
In my experience, two things matter with styluses on the iPad - precision and responsiveness.
With a view to replacing all the scraps of notes and sketches I have lying around, I bought a stylus recommended by an Industrial Designer friend and gave it a crack on my iPad: http://adonit.net/product/jot-pro/ ($45 including shipping to Australia)
I've used that stylus in some sketching app I can't remember and Penultimate (which has some palm avoidance settings that are somewhat but not completely effective). The stylus itself is well made and the little tip piece works well enough. For rough wireframe sketches and largeish notes, it all works fairly well.
But if you want to annotate your drawings by hand, I think you may find it frustrating. Writing text is pretty weak. My stylus sits largely unused and I'm sketching on paper as much as ever.
In stylus demos, ignore any moments where they circle part of a map, or underline something, or sign their name. Looks lovely, but none of that is especially hard with a cheap stylus and a sketching app, nor will most people be doing a whole lot of it.
Pay special attention to the moments where they try to write in any small detail and watch for the thinness, quality of the lettering and responsiveness to the pen. Did you see the collaborative drawing of the Sydney Opera House? For almost everyone, that's what the drawings will probably look like - a bit of a rough mess.
The collaborative features might appeal to others, but at no point in my work/home life am I usually sharing a drawing space with a colleague. I'm rarely excited at the idea of someone messing with my garden layout drawings or idea wireframes! If I'm dealing with wireframes for a client project, it's usually not on an iPad.
You are making some very good points, sounds like you are particularly familiar with the issues at hand. RE the operahouse stuff - the student that did that were going for a 'ken done' look - very scribbly:) I'd say the pen performance when dealing with small detail is very decent - not Wacom Pro decent but not far off. Might org a video to show the performance. By the way we're drawing up a list of internal testers, can I interest you in trying out Collusion and telling us what you think?
Cheers,

From what I can tell, lag is an issue for all the tablets right now?

The software was ok, but the biggest problem is still that typical stylus lag on iOS. Not much you can do about that due to iOS restrictions. It's early days for Collusion so i'm sure they'll come up with something.
BTW the inking weight system has nothing to do with the inking state of the pen (which incidentally is Binary), (so the fact you couldn't tell i guess is a complement to Sumo) the transmission of which is IR not ultrasonic. Last thing, there is indeed plenty of latitude to address several aspects of laginess in iOS that arn't restricted, you just have to look for them, and be prepared to invest a lot of time. We know because we're doing it right now, and your right - it is early days, and thanks for the thumbs up - we are indeed coming up with something:)
"nobody's nailed how to make the iPad a compelling every day productivity tool"
Really? Also, $139 seems like a bit high, but I could be wrong.
As for the price - yes indeed it is expensive - this is new and quite complex tech (sporting the worlds fastest cloud collaboration system - as you could imagine is somewhat different to slapping it up on EC2. It should be expensive, as we're not building it on the cheap:) Given it adresses a gaping hole in the market for a lot of people who want to use the iPad as a primary productivity tool, I'd argue it is excellent value:)*takes off marketing hat.. Hope to win you over in the coming months. Keep an eye on us.
Cheers,
Rob, CEO Collusion.
As for the app without the pen, that would certainly work. In fact the $139 level includes 2 promo codes for a touch-only preview version of the app (only usable until the public launch).
RE: The Pen Hardware. A few details (beats guessing eh?), we're working in partnership with Byzero of Korea with respect to the pen and receiver, and we are getting excellent results optimising hardware and software.
RE: Real world lag 'issues'as apposed to 1/2 speed video issues: We've publicly tested Collusion with about 100 people with a VERY early POC release - the same software as used in the video (which is now 3+ months old) very few commented on lag as being an issue - and that was with no serious attempt at lag optimisation on our software. As you can see some of these kind folk have come to our defence on this forum (thanks fellas). We are extremely anal about squeezing every last drop of performance out of our software and iOS for release to make using a pen on the iPad as good as it can be. We're confident that we're getting it right, and look forward to our next open invitation test catchup to show people first hand how Collusion is evolving, and yes we'll shove a video camera in there, and post links here:)
To those who have a problem with our name, we have dedicated a special FAQ just for you. See http://collusionapp.com/faq/#a1
Guys (that is an Australianism that includes all the female posters here too) - we recon we have the pen thing in hand - was that a pun (assume for a second it is)... there is a LOT of brainpower here (hacker news), please turn your attention to other things we are working on... please - its seriously cool stuff - if you think Collusion is just a note taking squiggly drawing app - look a little deeper.
I'll say this the pen is simply and enabling technology, a gateway to far far more interesting stuff. We know people fixate on the pen, and thats fine, but we think people once they have it, will stick will Collusion for what it does.
Final note, pen input on tablet is as important as a keyboard or mouse to a PC: Really important till the point where it 'just works' then hardly noticed thereafter. We've hardly noticed the pen for a while now;) You dont use your computer for the keyboard, and we've not built Collusion for the pen.
There are some big ideas in Collusion - we've updated our Kistarter page text to hint at them a bit more strongly. Please have a read.
