the general support was added already in 2015 (see release notes [0]) for one specific touch device used with one notebook back then.

Since then, however, the topic was not relevant anymore nor integrated with Sculpt. It boils down to write or port the touch device driver for the desired/specific notebook, calibrate/sync the resolution of the touch device to the currently used screen resolution in Sculpt and potentially additional UI work.
