Benefits of touch typing on task performance: I assume that when
comparing skilled individuals, two handed touch typing on a
traditional keyboard is faster, more reliable, and more
automatic, than the other methods of text input that you mention

check out Yechiam et al (2003). Discussing the benefits of touch
typing over visual typing, they state: One main distinction of
the touch-typing strategy appears to be the
