Computer hardware designers have built a lot of strange devices in the name of ergonomics. Witness: kneeling chairs, wave keyboards, and wrist rests that feel like they’re made of Jell-O. You can now add to that list the vertical mouse, a 90 degree spin on the conventional mouse that puts your hand in a handshake position as you push it around on a desk.
The creatively named Korean company Wow-Pen announced the Joy ergonomic mouse back in February, but the device just began shipping in the U.S. recently. Its makers claim that it reduces stress on the wrist by allowing your hand to sit the same way it does when it hangs limp by your side – vertically. As you might expect, they also claim it alleviates carpal tunnel strain and reduce fatigue.
