Why Did Touch Take 4 Decades to Catch On?
theodp writes "You probably saw media coverage of Bill Gates showing off touch-screen technology to his CEO play group last week. With the introduction of the iPhone and iPod Touch, touch (and multi-touch) technology — which folks like Ray Ozzie enjoyed as undergrads way back in the early '70s — has finally gone mainstream. The only question is: Why did it take four decades for its overnight success? Some suggest the expiration of significant patents filed during '70s and '80s may have had something to do with it — anything else?"
I think that the same reason why touchscreen technology never caught on until recently is the same reason why motion controllers like the Wiimote never caught on until the Wii, because the previous of both concepts where crap and didn't offer anything over a mouse, keyboard and joystick. Actually, what it really comes down to is that if a form of control doesn't give anything over the defacto form, then its pointless. How many stupid microphones and control devices have been released in the past 30 years that were no better than just pressing the button on a joystick. If it doesn't really understand that I'm saying "Fire!" instead of just blowing into it, then its pointless. It also has a lot to do with the interface being standard to the system. When its an addon, it just doesn't get as much attention.
This is for the same reason that command pipes/stdin/stdout will always be more useful in unix-like OSes than they will in Windows. Because they essentially come with the system and 90% of the programs are setup to use them. Same as why REXX was so much more successful on the Amiga than it will be on any other OS. If the Wiimote had been an option item, then the software wouldn't have been there and the Wii would have probably been a flop.
Touchscreens are visual interfaces, keyboards/-pads are haptic interfaces. For most devices, keys make more sense because they're always in the same place and the touch feedback makes it possible to use them without looking. I do not want a touchscreen remote control, for example. Touchscreens only make sense for complicated or multi-function devices and those haven't been portable very long.
Most technologies take a while to become mainstream. NAND flash was invented in 1988 and took almost 20 years to become mainstream. Linux was started in 1991?? and is almost mainstream.
Engineering is the art of compromise.

touch is junk and nothing out there that people buy uses it. MULTI-TOUCH caught on. multi touch was invented by two professors at the university of delaware, who founded a company that made the greatest keyboard of all time, the touchstream lp. jobs saw the inherent promise of multi-touch and bought the company and all its ip, in the process making everyone sign nondisclosure agreements and burying the company. the price of the greatest keyboard ever made, no longer available due to job's actions, has rocketed to over $1000 on ebay and keeps going up.
a lot of you are reading this and thinking of non multi touch products that are getting some sales; however they use the fundamental tech that makes multi touch work. multi touch was about figuring out the shape and pressure of the fingers being applied, in addition to distinguishing multiple fingers. this eliminates the "palm brush" problem that plagued early touch pads.

it took a long time for people to figure out what happened; in the end one of the delaware professors listed his profession as 'apple engineer' on a public political contribution and the mystery of the jobs touchstream "nuclear option" was solved.
the reason it's caught on "just now" is that it's actually brand new technology. hopefully someone someday will undo that damage that apple has done to the multitouch industry by buring it under NDA's and patents. in the meantime, they have usurped microsoft for title of tech company most damaging to progress. let's see how long they can hold the crown.
Seriously, touch-screen CRTs were an extraordinary pain in the ass. Aside from the gee-whiz factor, they were useless as input devices.
There's no failure quite as dissatisfying as a complete and total solution to the wrong problem.
Your question cannot be answered because it depends on incorrect assumptions.
Touch didn't "just catch on." It's been around forever and has been evolving steadily and is being used in more and more places. You're postulating that because the iPhone uses touch and Bill Gates did a demo that now, May 2008, it has "arrived"? Touch isn't just now "catching on," it's simply becoming more and more common as technology improves. The regular iPod has had a touch-sensitive wheel ever since the 2nd generation. Laptops have had trackpads for ages. PDAs have had touch-sensitive screens since, well, as long as they've been around. I've seen touchscreen kiosks and ordering screens (Arby's used to have them) The only thing I can say is that as touch technology improves in the same way that all technology improves--becoming cheaper and smaller, in addition to better--it's being offered in more devices where small and cheap matters--i.e., portables.
I had a touchscreen 17" CRT at home almost ten years ago, and while it was really neat--there's something really satisfying about actually pressing a link with your finger to 'click' on it--it was a pain (literally) to use for any extended amount of time. Touch works best when your arms can be at rest, which means your hands won't move much, which means a small device. Now, who wants to poke on a tiny screen on their desk, when they could instead use a mouse and keyboard to manipulate objects on a 20" screen? No one. So, where does that leave us? Where is touch useful? Ding ding ding! In tiny devices that are already in your hand. Or, to put it another way, it's not so much that touch is just now "catching on," it's that we're finally finding things that it's really good for. Like I said, a touchscreen is not a good replacement for a regular old mouse.
Multitouch is a nice new addition to touch technology, but you know what? I hardly ever use it on my iPhone. I rarely zoom in or out. I click and drag a lot, and double-tap to zoom in and out, but this is nothing that couldn't have been done on a mid-90s Palm.
Dear Slashdot: next time you want to mess with the site, add a rich-text editor for comments.
A finger is a rather clumsy interface device compared to the pinpoint precision offered by a mouse. And when the OS and all of the software on that platform is designed for a keyboard and a mouse, then change becomes hard.
Read Apple's user interface guidelines for developing applications and web applications for the iPhone. Touch screen interfaces truly require (to overuse the phrase once again) a new interface paradigm.
Multitouch trackpads, on the other hand, simply overlay gestures on top of existing mechanisms. A two-finger tap is a "right click". A two-finger scrolling gesture translates easily into "scroll wheel" input. All events which existing systems and software understand.
A "pinch", however, is a new type of input that has no translation. As such, software has to be reprogramed to understand that type of event, and then perform the appropriate behavior.
Any sect, cult, or religion will legislate its creed into law if it acquires the political power to do so.
