Title:
Discount Learnability Evaluation
Authors:

Abstract:
Learnability evaluation has traditionally required expensive and
time-consuming techniques. Practitioners have refrained from performing
extended learnability evaluation due to its prohibitive costs. We propose
a discount method for evaluation of an interactive system's learnability.
Our method is based on automated logging of user actions, detection of user
mental chunks, and observation of chunk size as it grows over time with
experience. We introduce a model for chunk detection, and present
experimental results validating the use of chunk size as an indicator of
learnability.
