Free Style USB Optical Mouse Strapped to Your Finger
I’m a little skeptical about the USB optical finger mouse. The potential is there, but I see some issues with the strap working loose and thus becoming more of a nuisances then asset. None the less, the optical finger mouse is worth a closer look.
So the USB finger mouse straps to your index finger via Velcro, then use your thumb to push two levers up or down for scrolling. There is a rotary navigation dial as well, and I’m guess you depress the dial for clicking?
