Touch typing refers to any systematic keyboarding where the eyes are not required. Many adults today are using the "hunt and peck" method, or a method they invented themselves. Because some of our children are keyboarding in a "hunt and peck" way from toddlerhood, I use the phrase Touch Typing to remind parent to do education here, and not allow the child always to "do their own thing." I love creativity and self-expression, but not when it leads to an artificially lower ceiling.
I've heard tales about alternativly arranged keyboards with wonderously fast and easy paths to 60 words/minute, eyes-free, and have not objection to these alternatives. I just never met a real live person who used them.
