Flash for Touch Screens.
Any major differences that I need to know about?
I'm guessing that wherever you release your finger on the screen represents a mouse click (?) - but what about dragging your finger accross the screen?
I need to know for sure...
Anyone got any knowledge?
Cheers
Jason
*edit* On thinking about it more - touch = mouse down, release = mouse up.
I can do dragging between on mouse down and on mouse up. Does this seem about right?

Yes we can
for flash (or any other app on the touchscreen device for that matter) moving the finger around on the device represents moving the mouse pointer,pressing represents left mouse button press. So far only apple has touchscreen technology advanced enough that they will soon release a device (the iphone) which can actually detect multiple touch inputs,all others handle it like mouse cursor on a desktop os,so there´s only one mouse pointer.
On a sidenote if you don´t have direct control over the sensitivity setting of the touchscreen device it can still be tricky,because with an over sensitive setting on the device it detects mouse move as mouse press too easily.
You can get around that in two ways then:
-work with double click instead of click (so detect timespan passed between two clicks)
-check how long it was pressed (detect timespan between moudeown/presss and mouseup)

that´s not soley true,- philips and many other companies have been researching on this field way longer as apple does
http://gizmodo.com/gadgets/gadgets/p...ept-199198.php
they (philips) were actually the first introducing multiple idnetifiers (like fingertips, or special objects), see:
http://www.pocket-lint.co.uk/news/ne...225/view.phtml
but if we are not only talking about using the fingers:
dot underestimate the industry leaders in light- pen technology: Wacom
http://www.wacom.com/lcdtablets/index_21UX.cfm
also (this time :P) worth mentioning microsoft who pushed the tablet- pc´s idea and their windows tablet edition.
slightly off- topic:
some timed ago logitec sold a computer mouse that had build in force feedback or better labeled as vibration functionality. Now the interesting part is that they added support for flash via JS in it- they way you could create games that let your mouse vibrate differently.
slightly off- topic2:
it´s also possible reading the scroll wheel data of the mouse in flash- some of the wacom tablets with expensive equipment do support some kind of air- brush pistol wich has unique features including the scroll wheel and some kind of distance control- maybe one could get that data (distance control) into flash.

yeah,sure i know there are lots of companies doing research and also creating actual devices in the touchscreen sector, i didn´t know any of em is advanced as apple regarding the point they actually sell a device which allows multiple inputs in mass market range soon.
I´ve seen many trade fair etc demos of multiple input devces but yeah,nothing like "next month in a store near you" for end users
i love the cintiq (and generally wacom stuff), think i´ll get one,too
I was interested in tablet pcs for years, since i started to do the first apps for em and then ms made that big move with the tablet pc specs "standardisation" to some extend and bringing out an own windows version for it some years ago, but yeah,i was always thinking they were still way overpriced, somehow they also hardly dropped much in price all those years, ones which are comparable with standard notebook cpu/ram/graphic card specs are damn pricey.
regarding your note on logitech/force feedback and using mouse wheel: yeah,that´s nice,i love such things,the problem on pc is that besides a keyboard and a 1 button mouse you can´t take any input device as granted to be available on user side (unless you of course only make your content for that one setup anyway ) which is very sad, i´d love to use such input peripherals but yup,its too much effort imho regarding most users won´t have it.
Regarding mousewheel i´d use it in a flash game if it makes sense and the game would otherwise require too many keys but again,one can´t expect all users to have a mousewheel so one has to code alternative key options for those who haven´t (heli3 is a good example for that).

we have a cintiq here at the university,- some students use it even for 3d- applications to paint,- draw poly´s and splines. Maya, zBrush, Mudbox, 3dsmax are just a few that support wacom tablets.
I myself have an Intius² A5 and it really is worth the money if you know what to use it for
almost the only user group without a scroll wheel are the macusers- even with the mighty mouse it might be something different and not be recognized as a scroll- wheel (rather a track- ball). But I like the idea of featuring a custom key to a game/ engine that can be defined by oneself- in case you dont fullfill the hardware specs.

my problem with other drawing tablets is a personal one:
With drawing i have two issues:
1.: I can´t draw freehand nicely with the mouse at all, i grew up with drawing tons on paper with pens etc and although i use the mouse daily of course, when it comes to drawing freehand it feels like a piece of soap in the hand to me,i can´t draw at all as good as with an actual pen and it also takes way longer.
So yeah,for that problem all drawing tablets would help.
but then comes problem 2 :
2.: I have to look where i draw, it feels highly unnatural to me to draw somewhere else than where i´m looking. Sure,drawing with a pen using drawing tablet is way better than using a mouse,but somehow i never got the same natural feel for it and again it takes longer for me than if i could look where i draw.
So yeah,for those reasons i´d prefer getting something like a tablet pc or cintiq, up to now the price was always the main thing holding me back.
The second thing holding me back is that yup,my work is at least 80% coding and at most 20% art creation right now (normally less),i´d like to get into doing more art but yup,as it is that won´t change anytime that soon
Regarding the mouse wheel: Its sad, but i still see readymade pcs sold here which have a mouse which only features 2 mouse buttons and nothing else :I

something I was searching before but couldn´t find before:

a multi- touch technology, pretty amazing!!!
nnatural to me to draw somewhere else than where i´m looking
that´s why you train your brain with some little practices.- sure it might be better drawing actually on the spot where your pen is but it is not so bad- personally I think I gain 80% of the precision & control compared to the real pen & paper. But if you are working for a longer time really intense you wont notice a thing,- it just feels natural then.
mouse wheel: I hardly see any mice in shops without it,- in the university, friends of mine everywhere mouse wheels- i´d carefully say imo. 95% with mouse wheel.

Not really needed,but pretty slick

yeah,nice man, sadly not the case for me
i had a drawing tablet and well,didn´t ever get used to drawing on it while looking at the pc screen.

yeah,well,depends what audience you´re targetting with your content. If its
(hardcore) gamers,so people who play a lot on their pc you can normally expect a better machine/peripheral setup than well,office users for example who may also have gotten the cheapest readymade pc or just use a ten year old one. Anyway, always good to offer alternative control options where it makes sense

, sadly not the case for me
to be honest it took about a year to actually use the tablet propper and frequwntly just because of the same reason- it just felt odd and I expected something different. but believe with practice comes skill & then you´ll love it

Style Through Simplicity
I think I'm right in saying that the top of the range wacom has a built in screen that displays exactly what you see on your monitor, so you can draw while looking at the tablet. Only problem is that it costs a fortune. Perhaps they will start introducing it on cheaper models over time.

Oh right, ok . Yea I would love to have one of them, but there is no way I would spend so much on something I wouldn’t use enough to make it worth wile. I'm like you Tom in that I mainly code, but do like to draw a bit too, so despite really wanting one, I can't justify getting one.

I think the LG Prada phone has touch screen with flash interface.
