A pseudo-mouse driver for the guest OS would position the guest mouse pointer at the position of the host mouse pointer within the VNC window, instead of using relative mouse movements and pretending to be a real mouse to the guest OS.
Some pointing devices actually report absolute position as part of their packet stream. Some examples:
- Synaptics Touchpad - Various PS/2 touchscreen input drivers - Any USB HID-compliant device canThe first two require a "knocking" protocol to unlock the absolute positioning data. Only the third has built-in support in Windows.
