A paradox? Not really. Some really nice and proper English scientists have racked their brains to change the conventional touch pad designs. More details in the Newscientist report: Source

This ”mouspad” scansyour fingertips to identify what you are touching. The sensor cam queries  your fingernails and pumps clear images. It then picks up your touch as well as the force applied, heck, even on a 3D surface. This is accomplishedd by evaluating the blood pressure underneath the nails  caught in images.

The English assert how easily and cheaply this could be produce. Your very next Asus may just have one!
