Crikey. You wouldn't want to sneeze.
One annoying problem with some alternate computer inputs is that they can't filter out unintentional inputs. Voice recognition software sometimes misinterprets something as a command, and suddenly it's done
something and you don't always even know what. I have a PocketPC, which has a touch screen, and brushing a crumb off the screen can cause hell to break loose.
Video control of the cursor.... Imagine if you had to swat a mosquito or something. I can just imagine a mish-mash of inputs, followed by an (intelligent) Hal responding "is there an error with your brain?" [

It'd be curser controlling cursor....
Anyway, this isn't contributing much, excuse me [
