Interaction Design

The purpose of the interaction design phase (as distinct from the user interface design and construction/testing phases) is to produce a design framework that includes:

  • A definition of the target audience described by personas and their associated goals
  • Common scenarios or usage patterns associated with each persona
  • A conceptual model that defines:
    • All of the data objects with which users will interact
    • A task-based objects-actions analysis
    • A lexicon composed of all the labels for data-objects and task-based user actions

An important first step is to define our business requirements: what are we trying to achieve or accomplish by producing this tool? Requirements include:

  • Creation of a tool targeted at the average web developer who may know little about web accessibility
  • Use of the OAA rulesets and evaluation library
  • Page-level evaluation of accessibility with a focus on rules

Ultimately, the interaction design phase results in a design framework from which the user interface design can proceed.
