The Age of Touch Computing
DigitalDame2 writes "In 2009, touch computing will go mainstream. More and more devices will be legitimately touch-enabled with gesture controls for browsing through photos, tossing objects around the screen, flicking to turn the page of a book, and even playing video games and watching movies. In fact, Gartner analyst Steve Prentice told the BBC recently that the mouse will be dead in three to five years. PCMag has a full look at touch computing — the past, the present, and the future — including an interview with Sabrina Boler, touch UI designer."
Also why would I want to be waving my arms at my CRT or LCD screen?
Just earlier today I was thinking about this. I believe that one possible sollution to the "gorilla arm" syndrome is to put the monitor in the place of the keyboard, and move the keyboard a bit down.
The second issue to address (all this IMHO) is the visual feedback. I believe that in order to make touch-based interaction feel more natural, the applications will have to present the information in a more familiar way.
In general, I believe that touch computing can be real and can have advantages as well, however, I also believe that using touch computing does not directly means keyboardless computing as they serve a different purpose.

Touch computing fails in every way possible.
I like my monitor perfectly clean. Using displays all covered in finger grease drives me nuts.
Your hands conceal parts of the screen while you're using it.
You can move a mouse over a greater distance much more quickly than your entire hand. It's also much easier to get to a specific pixel / small area with a mouse than with your fat fingertip.
People keep lauding the Minority Report UI like it's a good idea. Do you really want to have to hold your arms up like that and move them around all day?
Positioning the screen ergonomically for use as in input device puts it in a position where you're hanging your head looking down all day. The minority report problem obviously applies if you position your screen at the optimal viewing position.
Others have already mentioned it, but lack of tactile feedback is a big one. This is particularly important for programs whose UIs aren't that great. You hit the touchscreen button - the button didn't move and there was no sound. You can only guess that your button "press" didn't register because nothing happened... but you don't really know. I see this on ATMs all the time.
How is wasting half of your screen real estate on a keyboard a good idea? Oh, you can bring it up dynamically? Oh great, well then I guess you don't get to use keyboard shortcuts. That sucks.
You are using English. Please learn the difference between loose and lose; they're, there, and their; your and you're.
Try the touch pad on the new MacBook and MacBook Pro. It works amazingly well - and one of the reasons is that you don't "tap" to click, you click to click. As in, physically press down on it, and feel and hear a click. You can enable "tap" to click but it's off by default, and given the number of misclicks I've made on other touch pads, I rather like it being off.
Several things make this touch pad just work compared to other touch pads I've used:
So you get tactile feedback when clicking, you get a large work area, and you get all those wonderful multi-finger gestures. It works amazingly well, to the point I was trying to use the gestures on my Windows laptop after less than a day of using the MacBook.
Of course, this isn't quite the same as the "touch computing" they're talking about where you touch the screen. And the touch pad is nowhere near as accurate as a mouse (although it's good enough for day-to-day use).
But it does show to me that touch-based gestures do have a future - I just don't think I'll be touching the screen on a full-sized computer any time soon.
You are in a maze of twisty little relative jumps, all alike.
You've touched on my thoughts regarding touch screens. I have a tablet, iPhone, Storm, treo due to work. Also have a ATM card so more touch screen use there. Also have a few "real" laptops, blackberry curve, keyboards, etc.
What I've found is a touch screen is good for simple data input. Call it one-dimensional. Pick from this menu of choices. Manipulate this single object. Basically something you can do with one hand...usually 1-2 fingers. For this, it's quick.
Once you get more complex, call it two-dimensional, things slow to a crawl on a touch screen. Typing is either slow or error prone. Multi-hand manipulation? Well sure, but your eyes can't pick out enough detail over the area of two hands to be of much use. This is where a keyboard and/or mouse become much more efficient. They're faster and I equate faster with better.
So touch computing will grow somewhat. it will comtinue to be refined and useful for one-dimensional data input. Simple selection/manipulation. Good luck getting me to lift my hands off the keyboard to the screen just to do something i would with a mouse. Heck, i use keyboard shortcuts so I don't have to move my hand off to the mouse when possible. The time saved might be 1-3 seconds...but i do it a thousand times a day.
