  • Articulate Human Processor Model: A key model used to understand how people interact with computers.

HCI Introduction

  • HCI is a discipline concerned with the design, evaluation, and implementation of interactive computing systems for human use. (Card et al, 2009)
  • Key components include GUI (Graphical User Interface), web browsers, and IDEs (Integrated Development Environments)
  • A successful product must be useful (accomplish what's required), usable (do it easily and naturally), and used (make people want to use it)
  • Ubiquitous communication (high functionality systems, mass availability of computer graphics)
  • Mixed media (high-bandwidth interaction, large and thin displays, embedded computation, group interfaces)

Goals of HCI

  • Produce usable and safe systems
  • Understand factors that influence how people utilize technology
  • Develop tools and strategies to create suitable systems
  • Achieve efficient, effective, and secure interactions
  • Prioritize peoples' needs

Components of HCI

  • User: The person interacting with the system. Requirements of user must be a priority
  • Task: The action or series of actions a user takes in an interactive system
  • Interface: The point of contact and communication between a human user and computer system
  • Context: The environment in which the interaction occurs
