Editing Touch-sensitive surface (section)

== Stylus sensing ==
Some touch-sensitive devices also allow precision input from a stylus. 

Some [[graphics tablet]]s are also able to sense touch, being combined [[touchpad]]s.

There are also [[touch screen]] devices that also allow styli. Some integrate a fully-fledged [[graphics tablet]]s having separate sensing of finger and stylus.
Others (such as Lenovo's "AnyPen") that don't discriminate between implements
are usually regular touch screens with a higher sensor resolution than the norm.

A related technology is the [[light pen]]. The classic type of light pen works only on a CRT display, as it senses when the electron beam passes over the point of contact.
