Ask Slashdot: Where Is the Universal Gesture Navigation Set? 177

dstates writes "As a mostly happy new iPad owner, I love having lots of apps, but I have got to ask, where is the universal set of gestures for navigation? Pinch and open mostly mean zoom out and in, but sometimes you tap to open, sometimes double tap. Sometimes right swipe is back, sometimes there is a back button, sometimes you just have to go to home and navigate back down. Reminds me of the early days of GUIs when every application had its own menu set with different top-level menus and different placement of various functions. Made life chaos for users. We have been there, done that, and gestures are much worse. At least with a menu, you had a printed tag you could read. Gestures are all magic handshakes until you know them. Seems like the tablet community should not have to learn the value of consistency all over again." What gestures would you like to see made standard in touch-based interfaces?

    Navigation on a tablet (or smartphone) OS across all the major ecosystems is leaps and bounds better than it is on the PC. Take the common action of opening a Control Panel for an application, for example. For many Windows applications, you'll find it underneath a "Tools" context menu. However, some applications that use alternative GUI toolkits (Qt, Gtk, etc.) will put it in the "Edit" context menu to stay consistent with Linux/OS X tradition. Then there are the applications that put it in weird places like "File" or something. An even better example is Firefox; one presses Backspace in Windows to go to the last page visited. The same action in Linux is ALT+left arrow. I think it's different in OS X too.
    • by Bogtha ( 906264 )

      No, OS X is almost entirely standardised in this respect. To get to application preferences, you go to the application menu or hit cmd-comma. Pretty much the only applications where this doesn't work are full-screen games and apps mainly targeted at other OSs ported by people who don't care about platform conventions.

    • It's a menu, not a context menu. Also, Windows is the only oddball because there's never been a consistent place, although Tools seems to have become the standard until the Ribbon-style interfaces moved it to the nameless orb, now replaced by a menu button vaguely reminiscent of File. Also, I don't think the information about some of the toolkits is correct. Qt is capable of moving the preferences/options menu item on a platform-specific basis so it's always "right."

    The standard UIControl set that Apple provides for developers has standard behavior already built in. There are a few gestures that may be optionally enabled, but most are on by default.

    I'd love American Sign Language to become the universal hand gesture library for interacting with computers. People who are deaf already fluent in ASL would become much more productive than they might be now. Many more people who aren't already communicating with people who are deaf would learn ASL and become fluent in communicating with people who are deaf.

    There's already quite a lot of infrastructure for ASL right now, both in communicating with it and in learning it. There's a whole literature, a whole culture, a whole lingo with consumable artifacts.

    What would be really cool would be software translating between ASL gestures, English and Chinese. Everyone should get into the whole handwaving party.

    • Unfortunately sign language has a long way to go before it even reaches universality. Gestures defined by companies and product makers will win in that race to evolve. The reason is this, sign language is not even universal in it's own country. There's a misunderstanding by many (including myself originally) that sign language was merely English with hand waving. Really, it's not.

With video based input, it could be a good dictation system. It would actually be superior to even good voice recognition in many environments. Places like cubicles. Libraries, or any

        >> Actually, I didn't realize until reading your post that you could click on the corrected word to dismiss autocorrect - I though you had to click the X, which often leads to clicking the area to the _right_ of the autocorrect on very small screens (like my phone) which inserts the *insert expletive here* corrected word anyway.

      On the default Android keyboard space accepts the first suggestion. Above the keyboard is shown what you typed and then suggestions in order of likeliness so if you want what you typed you just touch it, otherwise pick a suggestion or use space. If you long press what you typed it is added to the user dictionary, which is very handy.

      The only thing I would change would be to make access to the cursor keys quicker, although the new selection thingy is much easier to position by finger now anyway.

    They have gone down the drain when idiots who are not aware that a "page down" key exists on your keyboard were allowed to make flash controls displaying long texts in the web.

    Honestly i curse always when i am presented with a really nice looking UI in the web which behaves exactly like the programer always believed an interface should behave and forgets to implement half of the expected semantics. Things i hate:

    a) ESC does not finish dialogs

    b) Return does not OK inputs

    c) Tab does not jump between input fields

    d) Links dont do anything

    e) Deactivated options are not marked (of marked in a way you only understand after trial-and-error)

    In that sense, the inconsistency we have with touchscreens only fits in.

      There is no "page down" (or PgUp) key on Apple notebook computers (They may exist on the desktop versions, I don't know). Also no Backspace... which is really no Delete since the Delete key acts like a backspace and doesn't do the normal things a Delete key does (like delete stuff).

      I think the point is that there are no "standards" or that there are lots of standards and everybody makes up their own and doesn't really feel obligated to follow them consistently.

Touch interfaces work well when they feel like physical interactions, but shoehorning “gestures” into them is completely missing the point. You can't build fluid physical interaction with rigid commands that happen to involve fingers instead of letters. Sure, use gestures under the hood if you have to, but don't force your end user to think about it.
