From an EU perspective, that page is quite wrong, especially with assertions like

The Force supposedly cannot be detected by any device that has yet been built anywhere in the Galaxy. Furthermore, the only people who can detect the Force are those few "gifted" individuals who are "sensitive" to it.

(EU introduced Force-detecting devices left over from the Jedi purges.)

or

If the Jedi ability to "see" the Remote with their eyes covered and only the Force to guide them is so central to the Jedi's repertoire, then why do Jedi engaged in combat against opponents with real blasters always deflect the bolts with their eyes open?

(I think Lucas himself wrote in a blind Jedi or two.)
