Human Computer Interaction Terms Chapter 2

T- Prototype

In a "T" Prototype much of the design is realized at a shallow level (the horizontal part of the T), but a few parts are done in depth (the vertical part of the T). A "T" prototype combines the advantages of both horizontal and vertical, offering a good compromise for system evaluation.

MUTTS

MUTTS is the acronym fro Middleburg University Ticket Transaction Service, our running example for most of the process chapters

System Ecology

System Ecology is the context provided by the surrounding parts of the world with which it interacts

Think Aloud Technique

The think aloud technique is a qualitative data collection technique in which user participants verbally externalize their thoughts about their interaction experience, including their motives, rationale, and perceptions of UX problems. By this method, participants give the evaluator access to an understanding of their thinking about the task and the interaction design

Horizontal Prototype

A horizontal prototype is very broad in the features it incorporates, but offers less depth in its coverage of functionality

Task Interaction Model

A task interaction model is a step-by-step description, including task goals, intentions, triggers, and user actions

Task Structure Model

A task structure model is a hierarchical decomposition or tasks and sub-tasks showing what tasks are to be supported and the relationships among them

Vertical Prototype

A vertical prototype contains as much depth of functionality as possible in the current stage of the project, but only for a narrow breadth of features

Artifact Model

An Artifact Model is a representation of how tangible elements (physical or electronic) are used and structured in the business process flow of doing the work

Iterative Process

An iterative process is one in which all or part is repeated for the purpose of exploring, fixing, or refining a design or the work product of any other lifecycle activity. It is the "wash, rinse, and repeat" characteristics of HCI

Photoshop, Lightroom, and Aperture

Photoshop, Lightroom, and Aperture are high-functionality software applications for managing and processing large collections of images and photographs
