Help For Those With Shaky Hands
maotx writes "IBM has developed an adjustible mouse adapter that compensates for the shakes of patients with hand tumors and other causes of uncontrollable shaking. According to the International Essential Tremor Foundation, in the US alone nearly 10 million people are affected by essential tremor, the most common form of hand tremors. This adapter will plug in between the mouse and computer and is compatible with existing mice. No word on which port is supported (ps/2, usb, etc). More info here, here, and here. It is expected that IBM will sell the adapter for under $100 USD."
Another semi-obvious possible use would be to utilize similar technology to make operating a mouse on a train (or other bumpy ride) less error-prone.
