However, another powerful approach to keeping users engaged on the current page is to create a virtual page. One aspect of GUI learnability is the degree to which the icons in toolbars and ribbons are identifiable and memorable-but current "flat" and "subtle" designs that promote strong visual consistency could hinder learning by reducing visual distinctiveness within a set of icons. transmitter causes impulses in the auditory nerves.
