Study Notes

Design Production

In detailed design, visual designers produce visual "comps" which are pixel-perfect mockups of the graphical "skin" including objects, colors, sizes, shapes, fonts, spacing, and location, plus visual "assets" for user interface elements.
A visual comp is a detailed graphical representation of the user interface elements.

Visual Design and Visual Comps

An asset is a visual element along with its defining characteristics as expressed in style definitions such as cascading style sheets for a Website.
Visual designers ensure consistency with company branding, style guides, and best practices in visual design.

Wireframes

Wireframes represent designs for screen layout and navigational flow, and are a natural extension of sketching and ideation.
They are used for documenting, communicating, and prototyping interaction designs, and are a popular tool in industry practice.
Wireframes comprise lines and outlines (hence the name "wire frame") of boxes and other shapes to represent emerging interaction designs.

UX Goals

UX goals are high-level objectives for an interaction design, stated in terms of anticipated user experience.
They are driven by business goals and reflect real use of a product, identifying what is important to an organization, its customers, and its users.

UX Targets

UX targets are based on quantitative data, including both objective data (e.g. user performance) and subjective data (e.g. user opinion and satisfaction).

UX Measures

A UX measure is a general user experience characteristic to be measured with respect to usage of an interaction design.
The choice of UX measure implies which types of measuring instruments and UX metrics are appropriate.

Measuring Instruments

A measuring instrument is a description of the method for providing values for a particular UX measure.
It is how data are generated; it is the vehicle through which values are measured for the UX measure.

UX Metrics

A UX metric describes the kind of value to be obtained for a UX measure, stating what is being measured.
There can be more than one metric for a given measure, and UX metrics can be objective, performance-oriented, or subjective, based on a rating or score computed from questionnaire results.
Typical objective UX metrics include time to complete a task and number of errors made by the user.
