Despite the promise of voice recognition and the allure of HAL, the talking (and listening) computer from the film 2001: A Space Odyssey, the vast majority of us still peck at a keyboard and push around a mouse to get our computers to do what we want.

Voice recognition, except for those unable to use their hands, remains a slower, less productive input technology.

I recently went on another odyssey in search of the perfect input device, tired of the wear and tear on my body that my current setup was causing. I was periodically pinching nerves on the same side of my neck as the arm I used to reach for my ergonomic mouse. The pain would last only a day or two, but it was a warning.

Computer mice cause the most computer injuries, says Deborah Quilter, author of The Repetitive Strain Injury Recovery Book and the Web site RSIHelp.com (www.rsihelp.com). From having previously tested out different mice and trackballs, I concluded it wasn’t my mouse itself that was causing me problems but my repetitive reaching for it.

So I hunted around for keyboards with built-in pointing devices, which would let me keep my arms close to my body, and for other ways to heal myself. The good news is that I believe I’ve succeeded, even though I didn’t find the perfect solution. The bad news is that my solution may not work for you. Although we all share much of our physiology, we’re all different as well. On the other hand, perhaps one of the products I looked at that didn’t work for me will work for you.

Exploring Alternatives

At the high end, the DataHand Ergonomic Keyboard (www.datahand.com), starting at a pricey $995 and with a steep learning curve, keeps the motion of your wrists, arms, and shoulders to an absolute minimum. Consisting of two modules into which you place your fingertips, it’s a device to consider when less radical options haven’t worked.

The Kinesis Evolution Keyboard (www.kinesis-ergo.com) is a clever, versatile split keyboard onto which you place a touchpad on either the right or left modules or, optionally, one on each. Starting at $299, it comes with a built-in palm rest, which you may like, but I didn’t. It prevented me from using a wrist rest that I had custom built earlier to keep my forearms high and stop my hands from bending up at the wrists, a frequent cause of wrist injuries.

The Focus 7200 Trackball Keyboard, distributed by, among others, Fentek Industries (www.fentek-ind.com), is very affordable, starting at $45.95, and the trackball is at the front of the keyboard, where it should be. But the keys are too wobbly for my taste, and the location of the Power key–where the Page Up key is on many other keyboards–caused me several times to mistakenly power down my computer while working.

The unit I settled on was Unicomp’s Endurapro 104 (http://store.yahoo.com/pckeyboards/keyboards.html), a $99 device that’s almost perfect. It features the same kind of built-in pointing stick found on laptop computer keyboards and the same “tactile click” keys found on classic IBM keyboards. My only real gripe was the small Enter key, although it would be nice if the unit were programmable and came with a USB instead of a PS/2 connector.

Could I have found the perfect solution by getting a company to design a single keyboard to my exact specifications? No such luck. DS International (www.dsi-usa.com) of Glendale, AZ, requires a minimum order of 500 keyboards, with development costs typically $50,000 to $75,000 per project; manufacturing costs are additional.

Keeping Mouse Moves to a Minimum

Despite the ergonomic benefits of pointing devices built into keyboards, you can’t move around as quickly with them as you can with a separate mouse. So it’s good to remember that, whatever your hardware, reducing the use of your pointing device–mouse or otherwise–can help.

Consider keyboard shortcuts, for instance, even though they require you to memorize them. The most basic ones–like pressing the Control and S keys to save a file–enable you to avoid having to move the mouse pointer to the File menu and select Save.

Check out the sites below for advanced shortcuts built into popular programs:

Another possibility is using a macro program to create even more advanced shortcuts yourself, which you can do along with using keyboard shortcuts. By automating frequently used procedures, a macro program can save on both mousing and keyboarding. EZ Macros (www.ezmacros.com), at $29.95, is the best I’ve found.
