Not necessary in the simplest of implementations...

The big display would mirror the tablet display. The tablet would
show a tiny pointer. How small doesn't matter because you won't be
looking at the tablet. The pointer location would correspond to
the current pointer location as shown by "developer options" on
anAndroid. That pointer would be driven by touch. That should be
easy enough, the only difference is that a relative pointer
position would be used instead of current finger point position.

Apparently 99% of the programming for this stuff is already done
on Android tablets. Probably also on iPads or whatever. It would
just need a GUI switch and to make a few tiny adjustments when
connected to a monitor.

Being able to toggle to a virtual keyboard (without showing it on
the monitor) wouldn't be anything special, either.

In our last episode...

Use tablet as touchpad when connected to big monitor/TV?

Instead of having to keep one's eyes on the tablet while clumsily
tapping around, why not turn the tablet into a touchpad when
mirroring the display of the tablet on a large screen? With that
setup, the tablet display wouldn't actually be mirrored, the big
display would look like a desktop computer display with a pointer
floating around on it. Also, the virtual touchpad on the tablet
could be resizable so that you could simultaneously show a virtual
keyboard (neither of which would show on the big display). Or
there could be a spot on the tablet display tapped to switch
between virtual keyboard and touchpad. Again, neither showing up
on the big display.

I guess the current workaround is to plug pointing devices into
the touchpad. But why not an elegant software solution instead.
