Navigation pattern icons may be added to the topic objects to show the manner in which a user may move
between the different dialogue acts within a topic. These navigation patterns include “All
All,” in which
each dialogue act is accessible from any single dialogue act, “Index,” in which all dialogue acts are accessible
from only one index dialogue act, “Guided Tour,” in which the user must navigate through the dialogue acts
in order, and “Guided Tour with Index,” in which the user may navigate the dialogue acts in order or jump to
a specific dialogue act using an index listing.
SINGLE TOPIC WITH DIALOGUE ACTS
A single topic is something that can be the subject of conversation between the user and the interactive
application. “Mission: Impossible III,” “Tom Cruise,” and “Paramount Pictures” are examples of single topics,
i.e., possible subjects of a dialogue between the user and the application. Dialogue acts are the informational
units that describe the topic. For instance, “Birthday,” “Filmography,” and “Biography” may be dialogue acts
within the topic “Tom Cruise.”
MULTIPLE TOPIC WITH DIALOGUE ACTS
Multiple topics represent an entire category of possible subjects of conversation. “Movie,” “Actor,” and
“Company” are kinds of topics. “Tom Cruise” is an example of “Actor.” Dialogue acts within multiple topics
describe the content of each instance of the multiple topic. “Release Date,” “Box Office Sales,” and
“Synopsis” are dialogue acts that might describe the multiple topic “Movie.”
SINGLE GROUP OF TOPICS
A group of topics is a subset of instances of a multiple topic and serves as a means of accessing those
instances “from scratch.” For example, a group of topics for the multiple topic “Movie” could be “Top
Grossing Movies of All Time.” From this list, users could access “Avatar” or “Titanic,” instances of the multiple
MULTIPLE GROUP OF TOPICS
A multiple group of topics represents a type of subset of instances of a multiple topic for which there is more
than one instance. Multiple groups of topics are typically preceded by a single group of topics that provides
access to the multiple groups of topics. For the multiple topic “Movie,” “Genre” is a multiple group of topics.
A group of topics exists for the genres “Drama,” “Comedy,” “Action,” and so on, and together, those groups of
topics may be thought of as the multiple group of topics “Genre” preceded by the single group of topics
“Genres,” that is the list of all movie genres.
SEMANTIC RELATIONSHIP WITH TRANSITION
The ability to transition between an instance of one topic and an instance of another is shown with the
semantic relationship with transition. From “Mission: Impossible III,” an instance of the topic “Movie,” one
may transition to “Tom Cruise,” an instance of the topic “Actor.” The transition act should also describe the
transition and indicate the cardinality of the relevant topics. For instance, when moving from an instance of
the topic “Movie” to an instance of the topic “Actor,” the transition might be “Has Cast” and the cardinality
might be 1:N because a single movie may have multiple cast members.
HETEROGENEOUS GROUP OF TOPICS
The heterogeneous group of topics is not unlike the traditional group of topics in that it gives users “from
scratch” access to topics. What makes the heterogeneous group of topics unique is that a single list may
provide access to instances of several different topics. The heterogeneous group of topics is often used to
strategically highlight certain areas of a website. A heterogeneous group of topics for a movie website might
be called “New Content” and include access to instances of the topics “Movie” and “Actor.”
that are accessible from every topic. These single topics are known as Landmark Content.
Sometimes, several multiple groups of topics may be listed in just one single group of topics. The single group
of topics “Now Playing” may give way to several more single or multiple groups of topics including “By
Theatre” or “By Genre.”

ISOMETRIC INTERACTIVE DIALOGUE MODEL
The Isometric Interactive Dialogue Model (IIDM) is a robust conceptual modeling framework for information
rich interactive appli
cations. Based on the Interactive
Dialogue Model developed by Davide Bolchini and Paolo Paolini and the isometric visualizations of web architecture pioneered
Paul Kahn, IIDM was designed to
provide designers and stakeholders with an engaging, flexible representation of the user experience using the objects below.
WAY SEMANTIC RELATIONSHIP WITH TRANSITION FOR COMPLICATED DE
The application or site root is represented by the “Home” card. This card represents the starting point of the
system dialogue and should provide access (this access represented by the dotted lines and arrows) to
each single topic and all single and multiple groups of topics.
After arranging the necessary elements on the isometric grid, resize the application carpet and place it
beneath the other isometric objects to visually group and unify your application or website.
