4. Concepts Definition

The following table shows the definitions for HCIDO concepts.

Concept Definition

Functional Prototype

A HCI Design Specitication that is a piece of code (i.e., a Software Item) intended to present basic functionality of an interactive system or of its components. It is developed for early evaluation purposes and cannot be considered the final implementation.

HCI Design Choice

A Software Design Choice that describes Mental HCI Design Choices. It is a physical representation of Mental HCI Design Choices, which can be used for communication and evaluation purposes (e.g., the fragment of a sketch showing the fields of a form arranged in two columns or a sentence written in a document describing the expected behavior after a form submission).

HCI Design Component

A User Interface Program that plays the role of Software Design Component and implements Mental HCI Design Components, having its own structure, appearance and behavior. It can be composed of other HCI Design Components.

HCI Design Object

A Software Design Object is an Interactive Software System that plays the role of Software Design Object and implements a Mental HCI Design Object.

HCI Design Proposition

HCI Design Specification

A Software Design Specification that describes Mental HCI Design Specifications, encoding one or more HCI Design Choices (e.g., a hand-drawn sketch or a text document).

HCI Designer

A Software Designer that uses his or her skills to directly contribute to the creation of a specification containing design choices about human-computer interaction aspects of the interactive software system being designed.

HCI Designer Mental Moment

Interactive HCI Design Component

A HCI Design Component that implements Mental User Input Resulting States and is expected to be triggered or not in certain conditions after actions performed by users of the interactive system

Loaded HCI Design Component

A Loaded User Interface Program that plays the role of Loaded Software Design Component (i.e., a copy of a programs that deals with user interface aspects loaded in the memory of an interactive computer system)

Mental HCI Design Choice

Mental Software Design Choices defining how the human-computer interaction should be implemented, including aspects related to the system’s appearance, the disposition of components in space and time and their expected behaviors in response to user actions.

Mental HCI Design Component

A Mental Software Design Component that can be perceived or triggered by users (e.g., a text label and a button) through the user interface.

Mental HCI Design Object

A Mental Software Design Object specified by a Mental HCI Design Specification that refers to an Interactive Software System being designed (i.e., what is expected to exist after the HCI design effort)

Mental HCI Design Specification

A Mental Software Design Specification consisting of a set of Mental HCI Design Choices. It represents the ideas that give form to a detailed description in the designer’s mind about HCI structural and behavioral aspects of the design object (i.e., it specifies the Mental HCI Design Object).

Mental User Input Resulting State

A Software Design Proposition describing situations, conditions or constraints related to actions that users can or cannot perform in a Mental HCI Design Component (e.g., a button that can only be clicked after filling all required fields in a form, a text input field that accepts only numbers)

Mental User Observable State

A Mental Computing Resulting State decscribing how a Mental HCI Design Component should be presented to users (e.g., presenting a collection of products as a list or in a 3x3 grid).

Mockup

A HCI Design Specification that is a higher fidelity Document depicting how the interactive system should be presented to users, similar to screenshots of the system’s future screens.

Presentational HCI Design Component

A HCI Design Component that implements Mental User Observable States and aims to present information that can be perceived through users’ senses

User Requirement

A Requirement that refers to User Goals (i.e., a Requirement concerned with users' needs or capabilities that should be addressed by the system, in order to allow users to achieve their goals in an effective, efficient, safe and satisfying manner).
src.: adapted from: (ISO 9241-220:2019)

User Requirement Artifact

Requirement Artifacts that describe User Requirements (e.g., user requirements written as user stories).

Wireframe

A HCI Design Specification that is a Document outlining the basic structure of the interactive system’s user interface (e.g., how elements are visually organized on the screen) in a low fidelity sketch, which does not address specific details such as colors and typography.
