The process of interaction design

The process of interaction design

1. Fundamental activities

   • Understanding the requirements
   • Producing a design that satisfies those requirements
   • Evaluating the design

2. Involving Users

   • "Expectation management": making sure that the users´expectations are realistic
   • User-centered approach
     • 1.- Early focus on users and tasks
       • 2.- Empirical measurements
         • 3.- Iterative design
   • Early focus on users and tasks
     • 1.- Users´tasks and goals are the driving force behind the development
       • 2- Users´behavior and context of use are studied and the system is designed to support them
         • 3.- Users´characteristics are captured and designed for
           • 4.- Users re consulted throughout development from earliest phases to the latest and their input is taken into account
             • 5.- All design decisions are taken within the context of the users

3. Basic activities of interaction design

   • Establishing requirements
     • Know our target and needs
   • Designing alternatives
     • Suggesting ideas for meeting the requirements
   • Prototyping
     • Designing products
   • Evaluating
     • Measured

4. Lifecycle model for interaction design

   • Simplified version of reality
   • Who are the users?
   • What do we mean by needs?
   • How do you generate alternative designs?
   • How do you choose among alternatives?
   • How do you integrate interaction design activities with other lifecycle models?
