DVDs are designed for random access and built-in interactivity.
Figuring out how to use these navigational opportunities
most effectively for a given DVD title is, in large part,
what makes the DVD production process different from that
of linear video format and interactive CD-ROM.
Another
crucial distinction between these two formats is ability
to support detailed graphical elements of computer graphics
vs. video graphics, because interlaced video can create
all kinds havoc on text and graphic elements. The real problem
comes when the client wants to put equal emphasis on both
set-tops and computers.
Good
information architecture is important for any interactive
project. The goal is a user experience that lets them get
anywhere within the content with the least number of clicks
– especially when navigating with a remote. Remote-versus-mouse
has a ripple effect on the function, graphic design, and
programming of the menus. The design and functionality of
menu structure is extremely important when creating a DVD.
For our customers, this functionality is generally what
makes the difference between using DVD and using videotape.
Here are a few design considerations when planning your
own DVD menus structure:
Make
important states explicit: Provide more feedback so the
user knows what has been selected and what is happening.
Make it easy to back out -- return to the previous spot
-- if the new page is not what was wanted.
Speed
up the transitions: Rapid response improves the user experience.
Unnecessary animations detract from the experience after
the first showing. With the careful use of motion, any effect
that you can create in video can be used as a transitional
element."
Develop
interactive standards for selection and cursor movements,
perhaps for other parts of the experience.
Have
the user test the result: Ask average viewers to do simple
things, such as find a scene of interest. Ask them to change
DVD settings, etc.
Consider
accessibility: the principles discussed in the NN Group's
recent guidelines for making websites and intranets easier
to use for users with disabilities also apply to DVDs.
