Hand to mouth
The keyboard has had a stranglehold on how people communicate with computers. Now a host of new technologies -- especially voice-recognition software -- are challenging its painful dominance.

Ottawa -- When the venerable Captain Jean-Luc Picard commands "Computer, get me Sickbay" and the machine follows the order, fans of Star Trek: The Next Generation are supposed to be getting a glimpse into the 24th century.
The forecast, however, is probably off by about four centuries. Experts say this science-fiction-level technology, which allows computers to understand and obey spoken commands, is likely just a few years off. In fact, technology already exists that allows us to tell our homes -- or at least a voice-recognition software package embedded into the personal computers in our homes -- to perform straightforward tasks such as changing the thermostat, turning on an appliance.
Voice-recognition software is just one of the many technologies that are promising to break the keyboard's stranglehold on how people interact with computers. It's a welcome prospect for many, since the keyboard is considered to be one of the worst-designed products in modern history, a monstrosity that's been able to resist a radical makeover only because there's been no viable alternative to date.
That doesn't even touch on the arrangement of the keys, a 19th-century relic that can be traced back to the typewriter's origins when frequently used keys had to be separated so the type bars wouldn't jam.
"It's a necessary evil," says Steve Kleynhans, a vice-president of Meta Group Inc., a Stamford, Conn.-based technology research group. "No end user could just sit down at a keyboard and start using it -- you have to learn how to type."
Or at least you did. Today, a range of alternatives to the keyboard -- particularly voice-recognition software -- is gaining strength and poised to make a dent in the keyboard's crown.
While some industry officials say the keyboard will always be one of the most common avenues for getting data into a computer, others are predicting its demise. "I think in 10 years everything [with voice-recognition software and other competing technologies] will be smooth enough, you won't need a keyboard," said Glenn Rogers, a vice-president of marketing at IBM Canada Ltd. -- and the executive in charge of promoting the company's voice-recognition software.
Other alternatives to the keyboard include touch programming, handwriting recognition, gesture recognition, electronic scanning devices, eyeball tracking, and -- newest and most direct of all -- tiny brain implants designed to allow those with severe physical disabilities to communicate with computers.
All have made drastic technological gains in recent years and are expected to get better and cheaper.
""This is the next big step. We're on the verge of a whole new set of interfaces, which are natural interfaces," says Mr. Kleynhans.
For two-fingered typists, that's great news. But it will also mean a major leap in our abilities to get computers to do what we want, similar in magnitude to when computing graduated from punch cards to real-time interaction, Mr. Kleynhans says. "The real big advances have come when we've fundamentally changed the way humans interact with computers." Don DePalma, a technology analyst with Forrester Research Inc. in Chicago, says the new interfaces will "be anything that takes advantage of senses we already have without having to learn a new skill."
"The bottom line in all of this is there's far more people who talk, touch and point than who actually type."
While still in their infancy, these technologies have already made their way out of the lab and are poised to play increasing roles in our lives. Touch screens have been around for at least a few years and are already in use in bank machines and at beer stores, for example.
Handwriting recognition has been around for years but is starting to fulfill its potential with the growing popularity of the electronic note pad, which offers a tiny writing screen and a special pen-like instrument to communicate with the computer.
These popular handheld products offer many of the same services as a PC, with applications such as Internet access, E-mail and word processing.
Gesture recognition, however, may hold only minimal potential. Experts say its use will likely be limited to tasks such as automatically activating the PC's screen saver when you walk away from the machine or turning down the stereo when you move to answer the phone. Scanning devices are already in widespread use in the retail sector but are seen to have limited use in the home.
Although unlikely to ever offer the same speed or market penetration as some of their rival technologies, eye-controlled software and brain implants offer potential breakthroughs for anybody whose ability to communicate is limited by illness or injury. Eye-controlled software, still in limited use, moves the cursor around the screen by sending a low-level laser from the machine to the user's eyeball to track the eye's focal point.
International Business Machines Corp., which is working on the technology in its "Project Blue Eyes," says it's accurate within about 1.1 centimetres on the screen. Manual manipulation is needed to do the rest.
Brain implants, first tried six months ago by researchers at Emory University in Georgia, allow the user to communicate by moving a cursor through signals transmitted from an antenna-like coil placed on the head.
"New interfaces for computers is going to be a huge growth market," Mr. Kleynhans says. "This is just the tip of the iceberg."
Many, particularly those who don't type, will not lament the keyboard's demise. Using a mix of technology from as far back as 1714 and as new as a few months ago, it's a device that relies on cryptic terminology (ALT, CTRL, ESC) and keystroke combinations that lack any intuitive basis.
There's no shortage of contenders to replace or augment the much-maligned keyboard. Of the seven leading challengers, voice-recognition software seems to have made the greatest gains and may also offer the most potential for widespread use. Some industry experts are already predicting its dominance.
"Speech recognition will eventually replace the keyboard," said Pierre Boisseau, manager of marketing and communications for Northern Telecom Ltd., a leader in the field. "It's so easy. It's more interactive, more natural, more user-friendly. It's the easiest way to communicate."
Mr. Boisseau said technology has outraced consumers' demand for it over the last 10 years and must now, in many cases, wait for buyers to catch up. "Ten years ago, R & D [research and development] was all about how fast you can get a technology, but now it's not so fast," he says. "We could come up with the ultimate speech recognition product but if the market isn't ready for it, it's of no use."
In the short term, Mr. Boisseau says, voice-recognition software will merely enhance the PC, as the mouse has done since its inception. However, it will become a staple. "People found a computer a lot easier to use with a mouse. So they used it."
Forrester's Mr. DePalma cautions that the technology, while ahead of its expected schedule, is not ready to knock off the keyboard. "What these guys are doing is taking advantage of the rapid improvement of the processing power that we wouldn't have thought possible even two or three years ago."
Some consumers are less restrained. "I'm sure the keyboard is eventually going to disappear," says Ottawa resident Tim Sullivan, who recently added a microphone and Dragon Systems Inc.'s NaturallySpeaking voice-recognition software to his PC arsenal. "It's great for someone who can't type -- I'm a two-finger guy."
Mr. Sullivan, 42, who also sells computer equipment, says he's amazed how fast -- 160 words a minute -- and accurately the software works. "Nothing will ever be perfect with voice recognition," says the technophile. "[But] I think it's come a long way in a couple of years."
But there are numerous critics of the current generation of voice-recognition software, who say it is neither accurate nor fast enough to replace a keyboard and that it still forces to alter their speech patterns to accomodate the computer.
Manufacturers say much of today's market for voice recognition software is comprised of lawyers, doctors and other professionals who need to document their work using only a single, steady voice.
"I'd be lost without this thing," says Frank Roth, a Toronto lawyer who's been through at least six different IBM upgrades since buying his first voice-recognition system about three years ago. Mr. Roth, an independent corporate lawyer, says the technology saves him vast amounts of time and money. "It's made an enormous difference to how I can respond to my clients."
Mr. Roth, an IBM loyalist, says he's noticed a vast difference in the quality -- and price -- of the systems he's bought over the years. With his first voice-recognition system, which cost about $1,400, he had to pause between words. With the latest ones, which start as low $69, he doesn't.
"The only downside is it's outdated about 10 minutes after I get it out of the box."
IBM Canada's Mr. Rogers says the technology has "come a huge, huge way. We all kind of have a concept of Star Trek, but it's here today."
IBM, one of the long-time leaders in the field, and Dragon, which has a licencing arrangement with Ottawa-based Corel Corp., are two of the three key players in voice recognition. The other is Lernout & Hauspie Speech Products N.V., whose Brussels-based language services division makes VoiceXpress.
The technology has made rapid progress over the last 20 years and is still evolving.
Meta Group's Mr. Kleynhans says there are four distinct levels of speech recognition software, though only two are widely available. The first involves close-ended queries from the computer, which the user answers verbally.
The second is dictation, or simply making text out of a single user's structured speech.
Mr. Kleynhans says the advancements mean bundled software packages that can help with domestic tasks such as opening a garage door or setting a home security system will likely be on the market within about 18 months. "It's probably possible right now. It's a question of how much money and energy you want to put into it."
Results at the third level, transcription, or turning less-structured speech into text, are still spotty. The fourth level, "natural language processing," the computer's ability to understand and process normal conversation, is even further away.
Beyond that, there is the truly Star Trek scenario of artificial intelligence -- where computers can think and sort through problems like humans.
The prospect of computers that think like humans is at least a generation away, says Mr. Kleynhaus. "It's not going to be in your lifetime or mine."
He says the development of more sophisticated ways of communicating with computers, however, is an important step in transforming the machines from idiot-savant tools to assistants that don't need detailed instructions. "A computer today basically acts like a moron."
A BRIEF HISTORY OF THE KEYBOARD
1714 -- First recorded patent for a typewriter taken out in England by Henry Mill.
1829 -- First practical writing machine patented in the United States by William Austin Burt.
1833 -- Improved machine produced in France. Like other early models, machine is designed chiefly for the blind.
1873 -- The first practical typewriter is invented by Christopher Latham Sholes and his associates and is marketed by the Remington Arms company. As the type bars tend to jam frequently, Mr. Sholes rearranges the keyboard so the most common letters are spread fairly far apart, creating the modern "QWERTY" keyboard, named for the letters along the on the top row, on the left. As all typists at this time use the "hunt-and-peck" method, the new keyboard slows them down enough to prevent jamming.
1874 -- Remington typewriter hits the market. It offers only capital letters for the first four years.
1878 -- Mrs. L.V. Longley, head of a Cincinnati school for stenographers, starts promoting ten-finger typing as a substitute for the two-finger method. Frank E. McGurrin, a federal court clerk in Salt Lake City, teaches himself to touch-type without looking at the keys. After winning a typing contest billed as a battle between the world's two fastest typists, the method begins to catch on.
1924 -- IBM produces the Electromatic typewriter. Electric typewriters come into wider use over the next decade, offering greater speed and less effort than manual machines.
1961 -- IBM produces the Selectric, which replaces type bars with a metal globe that moves across the surface of a stationary paper holder. It replaces the moving carriage of the traditional typewriter and allows for a variety of typefaces and special symbols. This, in turn, opens the market to scientific writing and various languages.
1970s -- IBM begins voice-recognition research.
1977-1981 -- Personal computers, such as the Apple II and the Commodore PET, hit the market but continue to integrate the keyboard into the computer case. Commodore PCs offer small, flat keys that are cramped together, similar to those on a calculator.
1986 -- The Macintosh Plus offers visual changes, including a numerical keypad and cursor keys.
1998 -- Cost of voice-recognition software falls to as low as $69. Other competitors to the keyboard include: Touch programming, handwriting recognition, gesture recognition, electronic scanning devices, eyeball tracking and brain implants.
