Human-Computer Interaction (HCI)
- Definition: The study of how people interact with computers.
- Fields of study influencing HCI: Computer science, behavioral sciences, design, and other fields.
- User interface (UI): The part of a computer system that allows people to interact with the computer, including both software and hardware (e.g., peripherals).
- Interaction perspective: HCI study involves human and machine interaction.
Importance of HCI
- Goal: Enhance the usability and responsiveness of computers to user needs.
Specific Areas of HCI
- Design methodologies and processes for interfaces.
- Methods for developing, evaluating, and comparing interfaces.
- Development of new interfaces and interaction techniques.
Design Principles
- Principles for User Interface design:
- Focus on users and tasks.
- Empirical measurement (e.g., establishing quantifiable usability specifications like number of users, time to complete a task, and number of errors).
- Iterative design.
Design Methodologies
- User-centered design (UCD): Focus on users in all stages of design.
- Principle of User Interface design (UI): Considerations during UI design (tolerance, simplicity, visibility, affordance, consistency, structure, and feedback).
Display Designs
- Support perception of relevant system variables and further processing of information.
- Defining purposes: Navigation, control, decision-making, learning, or entertainment.
- User processing capacity: Ability to process generated displays.
Thirteen Principles of Display Design
- Perceptual principles (e.g., making displays legible, avoiding absolute judgment limits).
- Mental model principles (e.g., pictorial realism, representing movement in a way a user would imagine moving in the real world.)
- Principles based on attention (e.g., minimizing information access cost, allowing users to focus on important information).
- Memory principles (e.g. replacing memory with visual information to reduce cognitive load).
Future Developments in HCI
- Ubiquitous communication (data and computational services available from many locations).
- Systems with high functionality.
- Mass availability of interactive graphics.
- Mixed media (handling images, voice, sound, video, and text).
- High-bandwidth interaction. Development of new input devices and interfaces.
- Thin, Large, and lightweight displays.
- Embedded computation (devices such as cooking appliances and lighting being connected to computers).
- Augmented reality (layering relevant information into a user's view of the world).
- Group interfaces.
- User Tailorability (Users can personalize and develop unique applications for their own use).
- Information Utilities(grow).
Human-Computer Interfaces
- Interaction point: the point where humans interact with computers.
- Flow of interactive information (input and output).
- Task environment: Conditions and goals of the user.
- Machine environment: Conditions of the computer and its location. Overlapping and non-overlapping areas of interactions
- Input flow: User initiating a task that requires use of the computer.
- Output: Information flow from the machine.
- Feedback: Confirmation and evaluation loop through the interface.
