The performance of interfaces is affected by human factors, which vary from one person
to another, and by the inherent characteristics of the various devices involved. A set of
techniques has been studied in order to improve the efficiency and efficacy of input
interface devices. These techniques are based on the modification of the motor scaling
factor, a transformation similar to the known Control-Display ratio (CD ratio).
Operation time, the accuracy of the task and user workload are the indicators used in
this work. By means of models based on the various human motor behaviors, the
improvement of such indicators has been demonstrated. Using some common input
interface devices, a number of experiments have been carried out to evaluate the
presented methodology. The results show that the overall performance of input
interfaces is significantly improved by applying such methodology.
