Do you mean something along the lines of taking any mouse, getting some way of identifying whether movement is up/down/let/right, and encoding that signal into the PCE in the same format as a HuPad would ? That would be interesting, but I'm not sure how one would identify movement so easily (or set sensitivity).
I am not thinking of any mouse, but of a PCE mouse. I thought it might be possible connecting the pad electronics to the h/v IR sensors and click buttons...no? Like throwing away mouse electronics and replacing it with a pad circuit?
Since the two wheels inside a mouse are basically nothing else than temporary switches (signal/no signal) shouldn´t it be like tapping the direction button(s) very fast, depending on the movement speed of the mouse itself?
Not possible? Stupid idea? Too complicated?
