You could try the following article:

"Touch-sensitive screens: the technologies and their application"
Int. Journal of Man-Machine Studies, Vol. 25, No. 3 (Sept 86),
pp. 249-269

This paper covers various techniques that use touch to enter
information into a computer. An attempt is made to evaluate and
rank them.

One aspect that is relevant in comparing touchscreens and mice,
is the "coarseness" of the input. A pointer can be positioned
fairly accurately with a mouse, but with a touchscreen different
choices, say, must be further apart.
