Touchscreens have been around since the 1960’s, possibly earlier. Many schemes have been used, everything from the current overlay technology all the way back to the old light and photocell matrix and everything in between. There are advantages to them all and many, many disadvantages. The current flurry of technology employing touchscreens was sparked by the innovative iPhone from Apple.
Steve Jobs despised the tried and true stylus. He famously said that we already have the best stylus: our fingers. Well, not so fast there, Mr. Jobs.
On large screen devices, like the full size iPad, my Asus Vivo Tab with Windows 8, and pretty much any device that is 8 inches or larger, your finger may work great. But, not so much on small screens.
I have found that it is not really the technology itself, but the user interface that is the real problem. Especially with the bloody on screen keyboard. If a hardware keyboard fan ever needed a reason to bring back an actual keyboard, one needs to look no further that the iPhone. (Hot on its heels: Windows Phone 8).
The iPhone’s onscreen keyboard is just awful. I constantly hit wrong keys. Now, some of it is my fault, most however, are not. When it isn’t being responsive, it’s just too damn small. Which is really surprising since the best on screen keyboard I’ve ever used in a small form factor is that on the Zune HD. Both Apple and Microsoft should take a look at that one. Funny, Microsoft designed it and promptly forgot it when doing the Windows Phone 8 OS.
Aside from too small or unresponsive, the predictive text is also a problem as is spell check/autocorrect. Now, these should be very useful features and, indeed, can be. BUT…when they screw up, they REALLY screw up. Yes, you can disable them, but, why should you have to? They should just work and they should give you an easy way to maintain and add to the database. If they do, then there’s no easy way to find it.
At any rate, why can’t these companies come up with decent on screen keyboards? Ones that work. Ones that are not hard to use and that just work. You should not have to think about HOW to type while typing.
User Interfaces are another source of frustration. For example, the antiquated Windows desktop is very difficult to use simply because its widgets are just too small for your fingers and designed to work with a mouse and not your finger. On iOS, they did a much better job with the UI, however, the multifinger gestures do not always work the same. And, sometimes you swipe down, sometimes you swipe left to right to do the same thing. iPhones present a real challenge due to the screens size. I find it difficult to play some games on this device because of the size of the screen. Other apps, like the music player app, can be difficult to use, especially if you have larger fingers. I find myself constantly selecting the wrong thing simply because the icons are too small.
In this new world of touch, designers need to take a step back and actually use the stuff they put out, before they put it out.I suspect a number of things would be caught and corrected prior to release. I’m sure such products would dominate.
