Usability of a device having a user interface that contains a plurality of user-selectable elements presented in a spatial arrangement that varies over time is improved by storing the spatial arrangement at an initial given time in a memory and, upon receiving user input at a later time, applying the user input denoting a selection within the spatial arrangement as at the initial given time stored in the memory, in order to achieve the automatic selection of the element that existed at the selected location within the arrangement at a period of time before the selection was made, rather than the selection of the element that exists within the arrangement at the actual time of the selection being made.
