Ok, a couple things here. First off, what I would hope Windows 7 brings to the table is integrated libraries for multi-touch, which app developers can use. Multi-touch devices like the ones from JazzMutant have been out for years, and even Wacom tablets have the technical capability to simultaneously recognize multiple tools. The problem is there isn’t much app support for these features. Yes, I could go on about how incredibly annoying I find it that a technology can be around for years, but it is only once Apple starts using it that people notice it, and then act like Apple invented it, but that is for another time.

As far as what it could be used for other than pictures and maps, the main application is creative. One of the biggest limitations of all creative software at the moment is the limit to a single cursor focus. Whether it is sliders in a sound program, channels in a 3D program, or tracks in a video program, having only one cursor that can only interact with one control at a time is very limiting. Some of this is gotten around right now with tools like pressure and tilt sensitive tablets, or dial/slider boxes, or tools like the JazzMutant or Spaceball. However, it would be far more useful if you could just reach up to the screen and “grab” what you wanted. Even for simple painting and Photoshop work, the ability to use more than one brush at a time would be fantastic.

Problem is, all of the current technologies at present require specific support by each app, or an app plugin to make it work. Then you have to spend time mapping the functions you want to that particular axis, and so on. If there were a device-independent OS library that just handled it all, then I think you would see a boom in alternate input methods, especially in creative software. No matter what the iPhone does or doesn’t do, we have yet to hear a word about Apple creating any desktop multi-touch libraries to do anything other than accept two fingers as a double click, and some rumors of mapping finger gestures to menu commands. Those are, at least in my opinion trivial and gimmicky implementations of multi-touch, that exist more to say “look we did multi-touch first” than to add any meaningful contribution to usability. So, if Microsoft is the one who is finally going to ditch the single-cursor, single focus methodology, then I say hooray for Microsoft.

Marc, I’m not dismissing the technology, far from it. But a lot of folks say that uses for the technology will come along, I’m just asking what they might be.

One thing is for certain, I don’t want specialized features like this that requires special hardware to be integrated as yet another feature in the OS. I’d rather an OS that is lean and mean over a bloated one that tries to do everything for everyone.

“Not sarcastic and not bashing MS. I am still waiting for ANYONE to give me a usage for multi-touch on a normal-sized screen device (not handhelds) where the technology can play a significant role. I have not been given one yet by anyone. It always comes down to manipulating photos and maps, and that’s not something that I do much on anything other than a handheld because with a bigger screen I don’t need to.”

It might not play THE significant role you want it to be. But it will play an additional role next to the existing input methods. For some areas (games, digital editing, etc.) it will open new possibilities. Point, touch, manipulate without the use of an extension will make interaction with a machine feel more ‘natural’.

Please keep in mind this technology is still rather ‘new’. Applications still have to be written for it and that will not be only for manipulating maps and pictures. Try thinking where multitouch can be useful instead of saying “I don’t need it”. Your needs aren’t always our needs.

Besides, what’s a normal-sized screen anyway? The trend for desktop pc is that screens are getting bigger and bigger. Multitouch interaction is more useful on a big screen than on a small screen where 1-2 fingers are more than enough, otherwise you hand will block the view.

Other than the hardware catching up with the software issues in the mainstream, this is cool technology, and it doesn’t need to be limited to one vendor; like Apple. There have been a plethora of innovations that Microsoft has funded in their Research labs, that no-one knows ever existed. That Nike iPod thing? MS had technology similar to that two years before Nike/Apple introduced it. Apple is great at marketing, so they know WHEN to get the cool-factor technologies out the door.

Besides, hasn’t anyone ever seen/heard of Surface computing? If you actually have seen/played with one of these things, you’d see that MS had already created this software interface to a hardware technology. As a technology, it has plenty of applications where physical manipulation of information is more natural to people than using a mouse. I think my 78-year-old dad could handle moving a picture around with his fingers more readily than using a mouse; the mouse concept is foreign to him. How about using it for patients recovering from a stroke? How about using it for teaching kids?

So, all-in-all, it’s not about WHO invented it, it’s about putting technology to good use.

One of things I found hilarious in the leaked whitepaper on WM7 last year was the whole gesture thing. They were talking about “shaking the device” in all sorts of ways (I guess they had to differentiate from Apple somehow) and all I could imagine looking at the diagrams of someone with a phone shaking it back and forth was my $500 tilt crashing into the pavement like a wiimote because I was trying to shake a new photo onto the screen in my photo album.

WM is my OS of choice but it has issues and is ugly at it’s core. Even the HTC Touch Diamond, which does a good job of masking WM is still like putting lipstick on a pig. One of the biggest issues to me is not software, but hardware. Passive touch screens like WM devices use that are not flush simply cannot do a decent job of mimicking the Iphone.

some examples of multitouch doing something other then maps, JK

This first appeared in FingerWorks products, not Apple, as implied in the post. Apple bought fingerworks and shut them down. Fingerworks products were crossplatform, and when Apple bought them out, they took their technology and made it Apple only. After that, used Fingerworks products would sell for much more than their new cost on ebay, and my stuff was promptly stolen. To this day I wish I had one of their touchpads back in my possession. I used to use it in Opera, even before Opera started doing mouse gestures.

Maybe the future of multi-touch for desktop PC will be a screenpad near the keyboard with the copy of the main screen on…

I can think of plenty of things that i do everyday that it would help me with. Of course i work in the media field so i might be the exception. My dream of running sound live with just a touch screen has to this point been ok but will excel with a multi-touch device with support.

Like touch screens now with gesturing it will really ramp up your productivity when multi-touch gestures come along.

I have to ask why wouldn’t multi-touch sell Windows 7, it has sold the iPhone. I can’t think of any other reason why i would even be interested in the iPhone than multi-touch.

I know if Vista had multi-touch then i would actually have bought a Dell Latitude XT and be happy as can be right now. I’m waiting now for Windows 7 and even more multi-touch hardware to come along. I do however hope they don’t mess up 7 like they did Vista.

Of course OS and Hardware is only part of the equation. Having software that will support multi-touch will be imperative.

Also remember that the iPhone is limited to two finger touch and their are times when i can see using 8 or 10 points at a time. Can you imagine how quick it would be to organize files into folders using multiple fingers? How about mixing audio and pushing more than one fader at a time? Some see this as a toy, i see it as a tool.

Food for though.

@FlyingShawn: Microsoft would have been better off showing something more unique. Like James said, we’ve seen similar things before.

I agree, though, that the big story here is that Windows 7 itself will carry this capability–although no idea if this will be available in all versions or not.

I would add that multi-touch makes sense with large displays (whiteboards) too. Why limit an interactive classroom or conference whiteboard, for instance, to one touch point and one user?

Is multi-touch all that useful on a notebook? Will it convince people to buy a new Tablet PC with this capability? Maybe for a few of us. But I think James is correct that we’re going to have to see more compelling demos to capture the attention and imagination of most people. Maybe if they’d shown multi-touch Solataire rather than Microsoft Paint…:-)
