The primary
problem with standard website navigation is that there is a user disconnect
when transitioning from one page to the next. For example, in a typical
situation, when you click on a navigation element, you are immediately moved
from one place in virtual space to the next with no physical indicator
explaining this to you. Just BAM! there you are. Some Web designers are trying
to smooth the transition by offloading some of the perceptual work onto the
human motion perception system. This is done by focusing the user’s attention
on the transition, and relating it to normal motion, which helps the user to
understand the change from one place to the next, much in the same way that you
do when you walk from one room to the next. For example, the first screen cap below
begins with the first page that you arrive at on the (demo) site. If we click
on the “Portfolio” navigation element (1) you will run through a transition
that leads you to page two. In the second screen you can see that the Portfolio
page slides from the left side of the screen to the right side of the screen (2).
This allows the user to understand their transition by using a standard motion
that we are already adept at understanding, which in turn tells them they are
leaving one page and arriving at the next. In the third screen, after the
transition has completed, you are still being giving location information from
a depth queue (3) in the form of a drop shadow that runs from the top of the
page to the bottom about a quarter inch from the right side. This is an indication
that you are looking at a different page by hinting that one page is on top of the
other.
Another way
that designers can move you through space is with a numbering system, much like
what I’m using for this blog. For example, if we look at the first page of the
instruction manual for Denon’s AVR-1910 surround receiver (1), we can see that
they have created an ontological (hierarchical) system that guides us through
the various functions that we may be interested in reading more about. By doing
this, they have provided us with a logical structure through which we
understand that if we are interested in Part Names, we need to move through the
manual to the a designated place in the “space” of the manual. Now if we shift
our attention to the Part Names and Functions page (2) you can see that each little
thing on the face of the receiver has a corresponding number (2.2 & 2.3),
which is accompanied by a brief description. Also note that they show you where
you are in the manual (2.1). All of these system work naturally with our automatic
cognitive processing relying on the actions of saccades and fixations to help
our brain understand the boundaries of the manual’s space and how we move
through it. Additionally as we turn the pages, there is a smooth cognitive
transition that allows our brain to understand where we came from and how we
arrived at the new place in the manual’s space.
