HCI Exam Prep January 2024

Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them.

Human: Single User, multiple local users or multiple remote users. Computer: Machine running program, often distributed, many different form factors and capabilities. Interaction: User provides input ⇔ Machine communicates results.

Human Computer Interaction focuses on enhancing human capabilities using computational tools because computer factors have improved over time, while human factors have remained constant over time.
