Study Notes
Design Process in HCI
- Design is a crucial aspect of Human-Computer Interaction (HCI) that involves understanding how people interact with technology and making things that affect how people work.
- Interaction design encompasses not only the artifact produced but also manuals, tutorials, and online help systems.
What is Design?
- A simple definition of design is achieving goals within constraints.
- Goals: What is the purpose of the design? Who is it for? Why do they want it?
- Constraints: What materials must be used? What standards must be adopted? What are the time and cost limitations?
Characteristics of Design
- Design is inherently creative and unpredictable.
- Design involves a process, not a state, and cannot be represented statically.
- The design process is non-hierarchical, neither strictly bottom-up nor strictly top-down.
- The process is radically transformational, involving the development of partial and interim solutions.
The Golden Rule of Design
- For HCI, the obvious materials are the human and the computer.
- Understand computers: limitations, capacities, tools, and platforms.
- Understand people: psychological, social aspects, and human error.
The Design Process
- The design process involves four main phases: Requirements, Analysis, Design, and Implementation and Deployment.
- Requirements: Establish what is needed by understanding what is currently happening.
- Analysis: Order the results of observation and interview to bring out key issues and communicate with later stages of design.
- Design: Move from what is wanted to how to do it, using rules, guidelines, and design principles.
- Implementation and Deployment: Create and deploy the design, involving writing code, making hardware, and writing documentation.
Design Process Phases
- Requirements Analysis: Find out what is currently happening, using techniques such as interviewing, videotaping, and observing people.
- Analysis: Use techniques such as task analysis, scenario-based design, and observation to bring out key issues.
- Design: Use rules, guidelines, and design principles to help with the design, considering constraints and trade-offs.
Organizational Design to Support Usability
- Usability engineers and user-interface architects must manage organizational change to support usability.
- Record design choices in some way, using notations and methods to record the existing situation and design decisions.
The Three Pillars of Design
- The three pillars of design can help user-interface architects turn good ideas into successful systems.
