Abstract
We introduce ephemeral adaptation, a new adaptive GUI technique that improves performance by reducing visual search time while maintaining spatial
consistency. Ephemeral adaptive interfaces employ gradual onset to draw the user's attention to predicted items: adaptively predicted items appear
abruptly when the menu is opened, but non-predicted items fade in gradually. To demonstrate the benefit of ephemeral adaptation we conducted two
experiments with a total of 48 users to show: (1) that ephemeral adaptive menus are faster than static menus when accuracy is high, and are not
significantly slower when it is low and (2) that ephemeral adaptive menus are also faster than adaptive highlighting. While we focused on user-adaptive
GUIs, ephemeral adaptation should be applicable to a broad range of visually complex tasks.
