Touch touch touch…
To be honest I don’t get it.
I touch my computer every day already. I use a mouse and a keyboard to do it, but to be honest I see very little sense in using my finger to manipulate objects on my computer. My finger tip is large, and my monitors (all 4 of them) are at a 90 degree angle to my desk. Why would I want to use my hand to reach out (and up) to manipulate objects on my computer screen when I can use the mouse to do it?
Now other devices like game tables, interactive kiosks, digital book readers, Maybe PDAs and stuff, that’s fine, but I have yet to see value in a touch screen PC that is not at very least stylus oriented. And on that subject, what is the hot thing about handwriting recognition. I specifically use a computer (and previously a typewriter) because my handwriting sucks :) Why on earth would I want to write on my PC screen? Sign a digital document? Sure, but now get someone to trust that ‘I’ signed it and we will be all set. That technology is still not proven yet and most people don’t really trust it. Using a finger print is a better option, and far more trusted, but still not entirely mainstream yet.
Yes, the touch demos that I have seen show fancy things like dragging and throwing photos around a table top, or playing games, or ordering off of a virtual menu, and those are all good examples of the use of touch technology, but at a very narrow focus and scope. The demos about interactive touch counters in the stores that allow you to compare multiple products side by side are cool too but also relay not JUST on touch but also on RFID technology that is not really related to touch. You could do one without the other. Games like chess, checkers, solitaire (every computer HAS to come with a copy of that right?) are fine for touch, but would you really want to play WOW or DOOM using touch?
I have YET to see one ultra compelling demonstration of using touch in an office environment that wows me more than a mouse does. Can you imagine trying to do photo-retouching using your finger? Editing code or creating an application form in Visual Studio using your hands? How about highlighting text and dragging it around or changing fonts using your hands? Now picture doing all that on a 17 or even a 21 inch screen.
I am not saying that touch does not have it use, it does, but on a somewhat narrow scope I think. I think you will see (my prediction) that touch WILL finally take hold at some point, but more along the lines of interface technology that we are already familiar with today. Give me a keyboard that I can reconfigure on the fly based upon the application that is active on my screen, and do it that way. Give my a touch pad to replace my mouse, or maybe two touch pads (one on each side of my virtual keyboard) so I can do multi-touch stuff. Maybe I will reach out to my screen a bit and do larger granularity things like flip pages on a large document, or open an application by tapping on an icon, but touch is not the generic answer to one problem.
It looks cool in movies, and sounds cool in high level technical talk, but in reality, where I live, I need what works, and I just don’t see touch being a PC related thing with a ton of impact like most do.
FORCE me into a touch only interface and loose me as a customer. I WOULD use a stylus more instead of a mouse on a laptop, but don’t make me write what I can type MUCH faster or you loose me as a customer.
My prediction is that the next big wave will be multi-modal interfaces. Provide me the ability to use touch where it makes sense, and then at the same time allow me to use a mouse or stylus or keyboard where it makes sense, at the same time and at MY whim. I want to scroll down in an online book a few pages by using my hand to grab and flip a PDF down a few pages then as they scroll by use my right hand with my mouse to grab the page as I see it, stop it, and then select a few words on the screen so I can reach up and press the bold button with my left hand on the screen? That’s great.
And before all you naysayer out there bring up all the cool ‘things’ from movies like Minority Report, keep in mind that was a ‘gesture based interface’ NOT touch based, and I think that is closer to being far more useful than pure touch, but a subject for another blog entry.
