Chapter 1 What is Interaction Design? Interaction design means Designing interactive products to support the way people communicate and interact in their everyday working lives. Is Interaction Design beyond HCI? The main difference between ID and HCI is one of scope. ID has a much wider net in terms of theory, research, and practice of designing user experiences. HCI has a much narrower focus being concerned with the design, evaluation and implementation of interactive computing systems. The process of Interaction Design involves four basic activities 1. Identifying needs and establishing requirements for the user experience 2. Developing alternative designs that meet those requirements 3. Building interactive versions of the designs so that they can be communicated and assessed 4. Evaluating what is being built throughout the process and the user experience it offers Interaction Design and the User Experience 6 Usability Goals Effective to use (effectiveness) – how good is a product at doing what it is supposed to do Efficient to use (efficiency) – once a user has learned how to use a product, can they sustain a high level of productivity Safe to use (safety) – protecting a user from dangerous conditions and undesirable situations Having good utility (utility) – Does it allow the user to carry out all their tasks in the way they would want to do them Easy to learn (learnability) – Can the user work out how to use the product easily Easy to remember how to use (memorability) – How easy is it for the user to remember how to use the product Positive User Experience Goals Satisfying Enjoyable Engaging Pleasurable Exciting  Entertaining
