Interaction Design Process

Interaction Design Process Why talk about process? • You need to gain some understanding of what is required for you to develop a user- centered educational product. What are the activities involved in the interaction design process? • Identify needs and established requirements of the product—If you are inventing a new product you may have to make your best guess to the answers to the following question. o Who are the target users? o Who are the stakeholders? o What kind of support is the product going to provide? • Develop alternative designs of the product o What conceptual design would meet the users’ needs? o What physical design would meet the users’ needs? • Build interactive versions of the designs o How do users react to the interactive product (can be paper-based prototype)? • Evaluate the design o How usable is the product? o How acceptable is the product? o What criteria are used to measure usability and acceptability of the product in terms of effectiveness, efficiency, safety, utility, learnability, and memorability? o Does the final product fit the purpose of the initial design? *You may want to design and develop what you think is cool or neat, but you have to make sure that you design and develop what the users would want and need. Why develop lifecycle models? • In order to finish with an end product of the interaction design process, you need to understand what are the activities involved in the process itself. • Communicating, negotiating, and developing lifecycle models of your interaction design process will decrease misunderstandings within your team. • Lifecycle models can be simple or very sophisticated; you need to develop a model that your team comes to a consensus.
