Q: What did Fitts' Law study?
Speed vs. accuracy in target tapping tasks.
What did Fitts' Law find?
A: As speed increases, accuracy decreases.
What is the Index of Difficulty (ID)?
A: A measure of task difficulty based on distance and target size.
What is the formula for ID?
A: ID = log₂(2D / W)
What does D represent in Fitts' Law?
A: Distance to the target.
What does W represent in Fitts' Law?
A: Width of the target.
Why does the speed-accuracy trade-off occur?
A: Due to limits in information processing and control.
What is impulse timing?
A: The idea that longer movements allow more time for corrections.
What is intermittent feedback?
A: Feedback used at specific moments rather than continuously.
What is a spatial trade-off?
A: Accuracy decreases as movement distance or precision demands increase.
What is a temporal trade-off?
A: Accuracy decreases as movement speed increases.
