mid-fidelity prototype

a prototype that provides the look and feel of the intended design but only rudimentary functionality

wizard of oz prototype

a prototype that relies on a hidden observer to change the interface in response to interactions

scripted prototype

a prototype that relies on users following a scripted sequence of interactions

animated prototype

a prototype that visualizes predetermined interactions

horizontal prototype

a prototype very broad in features, but offers less depth in its coverage of functionality

objective

data tha tis directly and indiscriminately observed

subjective

data that represents an opinion, judgment, or other personally based feedback

prototypes

early examples built to model, evaluate, and iterate on the interaction design of a product

verticle prototype

a prototype that contains as much depth of functionality as possible for one feature

low-fidelity prototype

a prototype that provides impressions of the intended design

design guideline

a general rule that should be followed in most designs

fully programmed prototype

a prototype implemented with all interactive features and back-end functionality

high-fidelity prototype

a prototype that closely resembles the final product

ux lifecycle

a framework consiting of a series of stages and corresponding activities that characterize the full evolution of an interaction design, system, or product

user experience

a user's behaviors, perceptions, and emotions when using a product

design thinking

an approach to creating a product to evoke a particular user experience

analytical evaluation

an evaluation based on analyzing the inherent attributes of the design rather than observing the design in use

empirical evaluation

an evaluation based on data collected while observing real user participants using the design

rapid evaluation

an evaluation method that is fast and less expensive, but at the cost of being less effective

rigorous evaluation

an evaluation method that maximizes effectiveness and minimizes the risk of errors, regardless of speed or cost

formative evaluation

an evaluation that helps to form the design

summative evaluation

an evaluation that helps to sum up the design

informal evaluation

an evaluation with ad hoc testing, no experimental controls, and a small number of participants

formal evaluation

an evaluation with controlled hypothesis testing, independent variables, and dependent variables

system concept

an initial vision or mandate for the system or product

interactivity

how are interactions realized

breadth

how may features are implemented

depth

how much functionality is implemented

qualitative

non-numeric data describing the user experience

quantitative

numeric data regarding the user experience

ux analysis

the analysis of the users' current work flow and activities to understand the users' work domain, needs, and desires

conceptual design

the communication of a mental model of a design vision through a theme, notion, or metaphor

ux design

the creation of the conceptual design, interaction behavior, and look-and-feel of the product

human-computer interaction

the design, development, and study of interactions between users and computers

contextual inquiry

the gathering of detailed data on the work practices of users

ux evaluation

the identification of bad design choices and usability problems through evaluation methods

contextual analysis

the identification, sorting, organization, interpretation, consolidation, and communication of contextual inquiry data

user interface

the physical and virtutual aspects of a system that the user manipulates and perceives during interaction

model construction

the process of creating models of the users, processes, and environment based on the extracted requirements

requirements extraction

the process of identifying needs and requirements from the contextual analysis

ux implementation

the realization of the conceived interaction design

design production

the refinement of a design through multiple iterations, each more refined than the previous

fidelity

to what degree is the intended design realized
