Windows 7 Touchscreen Details Emerging 152

Posted by Soulskill
from the fingerprints-on-the-windows dept.
nandemoari writes "Microsoft has revealed more about Windows 7 and its support for touch screen technology. The system sounds impressive, however, reports suggest it appears to have a high error rate. In an early version of the system, Microsoft found some problems. For example, both the zoom and rotate functions worked less than 75% of the time, often because the computer confused the two. To rectify this, engineers redesigned the system so that it only looks out for gestures specifically relevant to the program being used. This made a significant improvement: the zoom gesture was now recognized 90% of the time. The problem is that even a 90% success rate may be too low. If you can imagine how frustrating it would be if one in ten keystrokes or mouse movements didn't do what you intended, you can see why touch screen technology will need to be even more reliable if it's to truly improve the user experience. PC Authority has a related story about statements from HP, who don't expect such technology to replace keyboards and mice any time soon."

      The Microsoft Surface [what-is-what.com] was never billed as a touchscreen. It was meant as a language-less user interface. In that regard it works rather well: even primate peoples who have been shown the device could operate it, moving files, opening photos, and such. It is not a general purpose computer in any sense.

      Microsoft is trying to implement touch technology across an entire operating system and all its userland components.

      Apple has implemented touch technology on a specialized device with specialized hardware made specifically by Apple that, while quite impressive in what functions it can perform, is not even close to the broad range of tasks a fully fledged desktop/laptop computer and associated operating system performs.

      Which do you think might be slightly more difficult to implement?
      • Apple has done it on their MacBooks, too, since the newer unibody ones have a trackpad that does 1-4 finger gestures. I'm also not entirely sure wth "the broad range of tasks a fully fledged desktop/laptop computer and associated operating system performs" is supposed to mean. We're talking about an input device, and being able to recognize a number of gestures associated with that device. If you're trying to transform it into an "operating system-wide touch technology" you're already doing it wrong!

    I'm not convinced that the touch screens can replace a keyboard and mouse on a desktop, or even a laptop, for some time. Text is the big issue, and I can't see myself being able to achieve the same typing speed on a touch screen until there's some really good haptic feedback in place. While handwriting technology could come on leaps and bounds (and has done so), I already type faster than I can write, so this wouldn't be helpful to me. For the mouse there is definitely places where touch would work better, particularly for new users, but the precision of a mouse is better for certain applications (notably gaming) compared to stubby fingers and having them block your view of the screen. Even if Microsoft can get touch working nicely in Windows 7, it's still going to be quite some time until I'll be getting rid of my keyboard and mouse.

      It doesn't have to replace the keyboard and mouse, in most cases it just has to add to it, the mouse didn't replace the keyboard.

      There are some things that would be quicker with touch, some with mouse, some with keyboard, for instance touch, would probably be better at the (Reply To This) than having to grab the mouse, align it, click, the keyboard is better for this and the mouse is better for selecting/editing text.

      Plus, because of the difference with accuracies, things like Virtual 3D spaces, you could use touch as a main anchor to hold/move an object, the mouse to operate on the object, simultaneously.

      Or in 2D spaces, like Photoshop, you could use the mouse for painting/drawing, but touch to control rate of flow, or pressure, in a far more natural/instinctual way.

      Also, touch would be better for public access stuff, because keyboard and mouse are the same, no edges, breakable/grabbable/tied down inputs (ie: pens on chains) etc, and potentially they can be self-cleaning too...

    There is a distinction between gesture recognition and direct manipulation. With direct manipulation there is no recognition (using fancy algorithms like used in speech recognition). Succesfull multitouch applications use direct manipulation.

  • Fingerprinting is always a problem when you use touch screens.

    Especially after a snack or a meal.

    Aside from that - users also have different movement patterns, which causes every user to be recognized and to let the device learn the behavior of the user.

    And don't forget that gestures have different meanings in different cultures.

  • Screen are for our eyes. And we use hands to input. Screens are setup vertically because that good for our eyes. Keyboard are placed on our table because that how our hands are grown. Moving the screen to the table or move my hand to interact a vertical panel is no good!

    Gesture are actually good if it could be done on the keyboard. I owned a Touchstream LP keyboard (which is the exact multitouch technology that Apple acquired, google for its image), I enjoy doing gestures on it. However, the lack of touch f

    Sitting here at my desktop, monitor out of arms reach, I can't help but think that Touch is a useless feature. I'm not going to be swayed to Touch as a feature until I can make use of it. Perhaps if I was a notebook user I'd reconsider my enthusiasm. But that said, I think there's a way that they can attract desktop users...

    Some company needs to completely replace the 10-key pad on a desktop keyboard with a touch screen. It should be the same size as the 10-key pad or larger, and feature a 10-key on/off switch. In the 'on' mode, you would use it as a normal 10-key. In the 'off' mode, it would give the user a touch device which could manipulate the images on the monitor. The user might see a selection box on-screen targeting the area of the pad that is available. Touch gestures would allow manipulation of the desktop. Of course a mouse would still be used for most point and click interactions. It probably should use OLED for high angle visibility and should have soft ridges for tactile feedback when you enable 10-key.

  • I've never used such a device but I can see where a computer may become confused. When we touch the screen and move our fingers, we would more than likely change the distance between our fingers unintentionally when rotating in a circle. Maybe the solution is simple.

    When the computer detects that 2 fingers are on the screen, maybe simply displaying a circular template with which the user could follow when rotating, and downing the sensitivity would work. You could just create some kind of shadowing overlay

      I have a simple solution: stop trying to separate them into two discrete commands and just do both. Why is this even an issue?

      If you're trying to do precise manipulations, then don't use your fingers. Fingers are clumsy; that's why we invented tools, even if it's a virtual tool. You wouldn't want your doctor performing surgery using just his fingers to rip you open. Even with a mouse, if you want to drag out a circle, you use the circle tool and hold down a key to tell the software to constrain the result t

  • It may be all the rage, but I almost never use zoom and/or rotate. Normally I take some time to setup my application right, and after that I use it only if a document (e.g. a webpage) misbehaves. Once the character size is correct, I use the scroll bars. Now, the auto-rotate of camera's, PDA's, photo frames etc., that's something I find truly useful. I wish I had it for my LCD screen.

    Am I the only one that thinks that rotate and zoom are both rather pointless things to optimize? I've got a MS 4000 keyboard

    But Microsoft can fix this easily.

    When you touch the screen and it's not clear what you want, an animated character can pop up and say "Hi! It looks like you're trying to rotate the screen image!" and coach you on how to bend your fingers into the right position to meet the software's expectations.

    To prevent errors, when you're done, a dialog box can pop up saying "Do you really want to rotate the screen image? Allow/deny." Then there will be no errors... or any errors that do occur can be blamed on the user.

    And, of course, there can be a Screen Rotation Wizard to give you a simple six-screen walkthrough, and context-sensitive Help available simply by tapping your ring finger in the northeast quadrant of the screen while you're making your gesture.

    The Microsoft Way is that the computer should control the user, not the other way around. Once the touchscreen programmers absorb this fundamental principal, all their problems can be easily solved.

      Lay your touch screen flat. If it's uncomfortable to have your head looking down all the time, have the contents of the touch display be mirrored to a vertical screen.

  • Seem to be accepted fine with a 90% success rate. I've always noticed that whenever most people that don't use one every day pick up an iTouch/iPhone, for example, the error rate in typing and gestures can be even higher than 10% yet this does not deter people because the basic functionality like scrolling and "clicking" work fine. In my experience, people are willing to chalk up errors in slightly more involved gestures to "getting used" to the particular touchscreen's properties. I know several people run

    I can't believe someone else has not thought of that before [slashdot.org]! Anyone can clearly see why Microsoft is famous for their innovations! (i.e. as long as they don't follow the link and read it)
  • Imagine what the screen will look like with all that orange Cheetos stuff smeared all over it.

    Lame!

    And I won't get into what peanut butter and jelly will look like.

  • This industry has such a short memory. Some of you may remember the HP computer, the one with the butterfly on the screen? And the smiling actors touching the screen? HP blew about $85 million dollars advertising that computer and technology.

    It turned out people did not like touching their screens, for many reasons:

    (1) If the room temp is above 75F or your nervous about getting this paper done on time, you'll leave a smudge every time you touch the anti-reflective coating.

    (2) A finger is not a very

  • All this pinging back and forth over gesture-based interfaces vs. keyboards and mice... is wasted on me. I just want a nice wireless subvocal interface between me and my devices. When I use it I can speak aloud and the device won't take action because it knows I am, well, vocal. I guess the only danger of subvocal would be found in meetings at work where I find myself muttering profanities under my breath after the idiotic comments people make ;p

    As far as the actual subvocal transfer to my device... I a

  • Those looking forward to "gorilla arm" computing can rejoice. Unless multitouch gestures are supported on the trackpads of laptop mice, touchscreens on desktops is just a curiosity for kiosks and schoolkids.
  • This isn't new. I've been giving Microsoft products hand gestures for years.
