Human Computer Interactions: Introduction to HCI
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
