As space is limited, we direct readers to other sources for detailed discussions on Fitts' law and the utility of throughput [3-5]. Additional work of note is Fitts and Radford's 1966 experiment, similar to ours, and with similar outcome.

WebJan 1, 2015 · The correct level of data aggregation for calculating Fitts’ throughput is a sequence of trials. The premise for this is twofold: 1. Throughput cannot be calculated on a single trial. 2. A sequence of trials is the smallest unit of action for which throughput can be attributed as a measure of performance.

Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human–computer interaction and ergonomics. The law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target.
