# Principles of Practice Design ## Exploration Activity 9.2 **Speed-Accuracy Tradeoff and Fitts' Law** This activity explores the relationship between speed and accuracy in motor skills, using Fitts' Law as a framework. **Fitts' Law:** * Mathematically describes the relationship between speed and accuracy when performing aiming tasks. * Formula: MT = a + b\[log₂(2A/W)] * MT = Movement Time * a = Constant * b = Constant * A = Distance to be moved * W = Width of the target **Application and Experiment:** * The activity involves experiments that explore the influence of speed-accuracy tradeoffs in a specific setting. * A demonstration is provided at [http://fww.few.vu.nl/hci/interactive/fitts/](http://fww.few.vu.nl/hci/interactive/fitts/) to allow for practical experience. **Goals:** * Explain how Fitts' Law influences computer functions. * Propose redesign strategies for maximizing desktop efficiency. **Note** The provided text explains motor skill learning, practice design, and an activity to investigate the influence of speed-accuracy tradeoffs using Fitts' Law. It also suggests the use of virtual experiments via a website link.
