Throughput (TP), also known as index of performance or bandwidth in Fitts’ law tasks, has been a fundamental metric in quantifying input system performance. The operational definition of TP is varied in the literature. In part thanks to the common interpretations of International Standard ISO 9241-9, the “Ergonomic requirements for office work with visual display terminals Part 9: Requirements for nonkeyboard input devices,” the measurements of throughput have increasingly converged onto the… CONTINUE READING
