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.
