The USB vertical mouse might alleviate that pain you have from obsessive mouse clicking. I’m a little skeptical with products like this but after reading the description, there is definitely merit here.

The shape supports you hand in a fully upright handshake position which reduces pain and strain from forearm twisting which comes from a normal, horizontal mouse.

Introduced earlier this year, the USB vertical mouse is used at UC Berkeley, where it was developed, by nearly all the staff. It was found to be comfortable, easily adapted to, and promote a neutral wrist and forearm posture.

When I first saw the vertical mouse I thought it useless because when you went to click, the mouse would slide sideways. After a moment of thought (and reading) you understand the thumb provides the balance as it naturally opposes the finger position.

Albeit not a traditional looking mouse it does look very useful. If anyone at UC Berkeley is reading this, shoot me an email about it’s performance. I’ll update this post.

FYI - The vertical mouse is a Windows only device, but Evoluent does provide a link to a third party Mac solution for mouse drivers to run on the OSX.
