One of my most endearing memories of my mother is how she used to slap me on the shoulder (for my own good, of course) and implore me to "sit up straight!"

One of my most endearing memories of my mother is how she used to slap me on the shoulder (for my own good, of course) and implore me to "sit up straight!"

Alan Harper, the mooching brother on Two And A Half Men, uttered his own version of this same warning when he gave voice to the title of the fifth episode: "Last Thing You Want Is To Wind Up With A Hump."

But what's a fella to do when he spends the bulk of his day huddled over a computer monitor answering e-mail, writing Gadget Spot columns and generally doing whatever earns that next paycheck?

The USB Vision and Posture Reminder ($27 at gizgeek.com) is designed to warn you off the tendency that could lead to that hump. This ultrasonic sensor gadget sits atop your computer monitor and counsels you on the proper sitting position at the keyboard.

Blue lights emitted from this gadget indicate your head is anywhere from about one to two feet from the screen. Slouch closer than that healthy distance and red lights will flash. Maintain that improper position for 15 seconds and you'll hear a chime.

But if it's the dreaded carpal tunnel syndrome, or repetitive stress pain, that has you more concerned than the prospect of developing a hump, you might try the Foot Mouse, aka the Slipper Mouse ($200 from bilila.com).

Now before you start chuckling at the thought of computing with your feet, can you imagine driving a car using only your hands? Your feet have already been proven to be dexterous and efficient for navigation. All of a sudden, using those same feet to mouse around or left- or right-click doesn't seem so silly anymore.

The Foot Mouse can mimic every move of a regular computer mouse, and can add up to 10 additional pre-programmed shortcuts to its repertoire.

While this particular contraption has a look more reminiscent of pedals for a drum kit or a video game, the manufacturer makes a point on its website that's hard to dispute: "By the way, a mouse is supposed to run on thefloor, not on a desk."

So, as Mom the Gadget Gal might have said: "Sit up straight and try not to scuff the floor as you Twitter your friends!"
