For some computer users working on a PC all day is a literal pain because of all the repetitive stress from typing and using a mouse. There are many different types of ergonomic computer peripherals on the market and some work well. A new ergonomic mouse is being announced that was developed by two major medical universities in Holland.

The mouse has the rather odd name — HandshoeMouse. You might expect it to be shaped like either a hand or a shoe thanks to the litany of strange peripherals on the market. The HandshoeMouse has extensive medical studies to back up its strange design.

Using a mouse and keyboard for hours everyday can have some bad effects on the wrist and fingers. When bloggers begin their careers, they start out with beautiful model quality hands, but after awhile they look down and realize that they’re typing with withered witch hands. Okay, not really, but it takes it’s toll. Repetitive stress injuries can cause a lot of pain, which is why you want an ergonomic mouse. And Humanscale has an odd one.

They’ve announced the adjustable ergonomic mouse called the Switch, which can be used for right or left handed users. The Switch has a 45-degree angle on the bottom to help minimize wrist stress and to help it look somewhat like on a boat. Also has a navigation dish that helps prevent injury from constant scrolling. If you’ve ever seen an injury from constant scrolling then you know it can be a gruesome scene, often followed by shouts of “Blogger Down!” and cries for help. No word on price yet.

Kinesis has dropped a pair of new accessories that will make their Freestyle keyboards more ergonomic. You be the judge. The Freestyle V3 accessory clips beneath the base of the keyboard and gives you three different slope settings, while the Freestyle Ascent Multi-tent will let you set each half in ten degree increments all the way up to 90 degrees. It will lock them in at the desired distance apart from one another and could probably let you use your keyboard as bookends if you wanted. The V3 costs $25 and the Ascent comes in at a whopping $200. Great way to play with your keyboard and type sideways.

We’ve seen our share of concept mice here at the Brick, but this one tends to hold your eye and make you pause. It looks somewhat sexy, yet unfinished. It’s almost prententious. The City mouse is designed by d-Vision and has a shape that’s supposedly much more in harmony with how we use our hands.

The design means more precise movement and fewer repetitive stress injuries. As far as anyone can tell, you don’t slide this thing around on your desk. You tilt it, rocking the curved bottom to move your arrow. It’s nice. I like it. I would rock it’s curved bottom, for sure.

Computer ergonomics is a science that keeps getting better and the Switch Mouse concept another attempt to move it forward. The Switch Mouse sits snug in your palm, which lets your shoulder muscles do all the work, taking some strain from your hand muscles.

It also features an integrated pad to keep the heel of your palm comfortably in place while you are not using the mouse. A circular joypad is used for scrolling. So tapping your finger will allow you to scroll up and down and side to side. It can also be adjusted for length which gives you the perfect fit. It’s an interesting idea and may well prove useful.

Here’s a mug designed with a thin contour at the top that’s slightly curved to conform to your lips. I can only speak for myself, but I’ve been consuming liquid beverages all my life and I haven’t found a need to buy myself a special cup due to unwanted spillage or slobbering all over myself.

But if you’re someone who can’t manage to drink your morning coffee without spilling it all over yourself, maybe this would help. A sippy cup is probably far more traditional, however. I would suggest that if you’re an adult and find yourself needing a special cup, then you probably need a special hemet as well.

The name “Wow-Pen Joy” doesn’t exactly inspire much confidence in this new fangled mouse. My first impression is that it looks an awful lot like you are giving your desk an ultrasound. I’d be curious to know if it finds anything. Hope they used enough lube. This device is set to be released in North American and Sweden sometime next month, by a Korean company called WOW Technology.

I can almost be sold on the fact that the shape of this thing could provide for a more natural way of using a mouse, but then I figure that over time it would probably just cripple NEW areas of your wrist. For $30, it won’t break the bank for you to find out.

WOW TECH has a newer version of their ergonomically designed Wow-Pen mouse coming to the U.S. later this month called the Wow-Pen Traveler. The Traveler, like the “eco”, has a unique design that lets you hold it more comfortably like a pen to put less strain on your wrist and arm according the company. But this mouse also packs a few more nice features into is odd-looking design.

Sighted at the IFA trade show currently taking place in Berlin is this funky red ergonomic keyboard. Sure, we’ve all seen/used keyboards in the past that have promised to save wear and tear on our fingers but this nifty little circular keyboard was designed in mind for the serious gamer.

Toshiba made it and owns the patent on it. There are 55 keys circled around the pad; notice how this keyboard is a QWERGT design and the O, B and K keys are separate buttons? Toshiba says that their keyboard has extra large control buttons to make playing games easier for your digits.

Microsoft released news of a new keyboard and mouse combination targeting those that are at the computer for extended periods of time and could benefit from a more ergonomic design. The Natural Ergonomic Desktop 7000 bundles the Natural Ergonomic Keyboard 4000 with the Wireless Mouse 6000 together for a $150 package that should hit shelves in July.

Both components of the ergonomic desktop connect through 2.4 GHz RF-wireless connections with a USB receiver. The keyboard keys has a winged design which according to Microsoft will give your hands a more natural …
