Supporting Transitions to Expertise in Hidden Toolbars
summary
Four hidden-toolbar designs (ButtonOpen, Timeout, DoubleTap, Swipe) are implemented and tested with 24 participants performing 12 blocks of 10 selections; DoubleTap and Swipe provide spatial-memory shortcuts that cut selection time by about 700ms faster compared with visual-only designs, users adopt shortcuts to roughly 90% usage by the final block, errors rise from under 1% to about 5% for shortcut methods, and corners yield ~200ms faster selections while Swipe is preferred by 18 of 24 users.
