Keyboard and Video interfacing

I was thinking about trying to do a project that involves a PC keyboard(and
maybe mouse) and possibly a PC video monitor.

Can someone point me in the right direction to get started? I'd like
basicaly to "sense" or "transform" information between the data paths of the
pc and these devices... the keyboard one is sorta like a data logger type of
thing but actually is something else.

I'm sure the PS/2 port for the keyboard/mouse is very easy to handle but
what I'm woried about is for USB keyboards... not sure if the protocol is
standardized... if so then it should be pretty easy to interface using a PIC
that supports USB?

What kinda signals come out from the graphics card to the video monitor? I
assume there are both analog and digital outputs since I've seen newer
graphics cards with D/V out. Would it be relatively easy to "sample" the
video output of a graphics card and transform it then sent it along its way
to the monitor?


(I'm more interested in doing this in hardware than software)

Thanks for any info,
Jon
