Great User experience (UX) is Usability + Graphic design + Accessibility

Accessibility is the concept of whether a product or service can be used by everyone—however they encounter it

Usability is concerned with whether designs are effective, efficient and satisfying to use.

UX at the boundary between supply and demand

Modular vs integrated boundaries and UX

Domain specific vs. domain independent UX

Domain specific UX

Domain specific UX is different because there’s a new cost to acquire it for each customer, product, or use case. If an interaction designer wants to increase their domain specific knowledge, they have to stop designing interfaces and go research for a while. Then they have to analyze what they learned and synthesize it into conclusions that are general enough to create requirements and design against. Looking at the firm as a whole, domain specific UX belongs to the demand side. It’s about understanding what to produce and sell.

Domain independent UX

interface boundary
- The Design of Everyday Things or Tufte’s The Visual Display of Quantitative Information
back-end boundary
- domain-driven-design
- martin-fowler's refactoring

Domain independent UX should absolutely pervade the organization. It belongs to the general skill and knowledge of each supplier at their link in the chain. It’s part of learning to be a good designer, programmer, marketer, salesperson etc. Looking at the firm as a whole, domain independent UX belongs to the supply side.

    - color-bind people can see contrast but not hue differences.
      - use color-blind simulators
  - use of color

  - if you’re using color differences to convey information you need an extra cue
    - but if you’re using lightness and darkness to convey information, you don’t need an extra cue, as long as the contrast difference is high enough.
    - forms require colors to be assigned with meaning (red, green). But color is not enough because of blind people. Therefor an extra cue is required
      - same with status indicators
    - color contrast is not the only cue at play. Indicatint visual depth by play of background-color nad text color.
