Figure 10. Pop-up advertisement with ambiguous grouping
Note. The ‘Join Today!’ link groups by the principle of closure within the pushbutton in the center of the screen.
However, this link also groups by the principle of similarity with the underlined textual links that surround it.
From the pop-up advertisement example, it becomes clear that unwanted
information sorting can limit exposure time to user interfaces. What is not clear is how
the information in these interfaces is perceived and grouped within these time limits. The
pop-up advertisement example demonstrates a situation in which the user is viewing the
information within an interface for the first time. But what if users have prior experience
with the information on a display? In these cases, are concerns about time limitations
relevant?
Repetition of familiar tasks. When users observe an interface that they have seen
previously and are traveling back through it, they may not require as much time as those
who are using the interface for the first time. It is likely that experienced users travel
through familiar interfaces as quickly as their memory will allow them. Do these types of
users perceive the same elemental grouping as first time users?
