Introduction
As a new medium, interactive TV (iTV) allows the user to access and navigate information in a different way. In order to clearly illustrate such an experience, the information architecture deliverables demonstrate a more cinematic approach to mapping out the user experience. For example, a “site map” is not an appropriate document – because it is not really a “site”. On the other hand, a “process flow” provides a similar function while not constraining the experience to a particular hierarchy.
The following documents were created in the spring of 2001 for a prototype of an interactive cable channel which would allow the user to access their cable account and change their services.
Process Flow
People have become accustomed to using the TV remote to change channels and select items from a factory preset menu in a basic linear experience. With iTV, the remote uses the same buttons to navigate through a potentially non-linear experience. The process flow document is a crucial tool for working out how this experience will flow.

Personae
This interactive television program will be used by an audience which ranges from those who have no experience with new technologies to the savvy techie. The identification of personae to represent this varied audience at the beginning of the project allows the rest of the design to be based upon the needs of the user.
The user personae for most iTV projects already have a mental model for how the television should work. Interactive television challenges the user to break that model. Some personae will have an easier time navigating the iTV experience than others, dependent upon their prior experience with technology and other personality factors.
Wireframes
The safe design area for an iTV screen is limited by the need to use large fonts in order to be legible on the television set.
The wireframes provide an initial structure for navigation and content on each screen. Generally, the less content on the screen, the better the screen looks on the television. The amount of content that you are able to fit within the safe area can often cause a re-evaluation of the process flow.
ZOË, 26 YEARS OLD
Zoë just signed up for the new digital cable services offered by her local cable company in Denver. She follows the new movie scene closely and is really excited about having access to multiple movie channels. Zoë lives alone and on and flips around while she is online. Zoë used to have to lookup TV listings all the time to find the name of a movie she came across, but that is no longer an issue with her new cable. Now the problem is weeding through the incredibly long list of options! Zoë considers herself an expert Internet user. She works as a paralegal and uses the Internet extensively to do research for the lawyers at her firm. At home she uses the Internet to comparison shop for any big purchase she might be considering (she went online to help her decide between cable and satellite). She has a tendency to multitask by being online and watching TV. Rather than looking up a show’s website or chatting with other “Survivor” fans, she likes to catch up on her email and look at those stupid little games her brother is always sending to her. Normally she wouldn’t even bother, except that he likes to call her up and quiz her on them. Zoë mainly uses her interactive cable system to order movies from pay-per-view and to check the weather and time before she leaves for work. The technician who installed her cable told her that they would be adding new services soon, so she keeps an eye out for new and interesting iTV services to come along.
Zoë’s Characteristics:
Zoë’s Goals: Find out if there are new services available. Subscribe to a new movie channel. Unsubscribe to a channel that she never watches. Pay her cable bill using her tv.
