Abstract
Fractional expression D/W in Fitts' law can be understood theoretically in two mutually exclusive ways. In D/W one can view either a single theoretical entity represented by the quotient of the division of D by W (assumed to have been done), or two theoretical entities represented by D and W, the operands of the doable (but undone) division. The paper discusses the theoretical and empirical consequences of the usual failure to distinguish these two understandings in Fitts' law research.
