Human-Computer Interaction (HCI) Cheatsheet
Overview
Human-computer interaction (HCI) is the study of how people interact with technology. HCI is an interdisciplinary field that includes aspects of computer science, psychology, design, and engineering. Here are some fundamental concepts in HCI:
- User-centered design: User-centered design is an approach to design that focuses on the needs and preferences of the user. User-centered design can be used to create technology that is intuitive and easy to use.
- Usability: Usability refers to the ease with which a user can interact with technology. Usability can be evaluated using metrics such as efficiency, effectiveness, and satisfaction.
- Accessibility: Accessibility refers to the design of technology that can be used by people with disabilities. Accessibility can be achieved through the use of assistive technologies and inclusive design practices.
Design Principles
Design principles are guidelines that can be used to create technology that is user-friendly and effective. Here are some fundamental design principles in HCI:
- Consistency: Consistency refers to the use of consistent design elements throughout a system. Consistency can be used to make technology more intuitive and easy to use.
- Feedback: Feedback refers to the provision of information to the user about the state of the system. Feedback can be used to improve the usability of technology.
- Simplicity: Simplicity refers to the use of simple and clear design elements. Simplicity can be used to make technology more accessible and easy to use.
Evaluation Methods
Evaluation methods are used to assess the usability and effectiveness of technology. Here are some fundamental evaluation methods in HCI:
- User testing: User testing involves observing users as they interact with technology. User testing can be used to identify usability issues and areas for improvement.
- Heuristic evaluation: Heuristic evaluation involves evaluating technology based on a set of design principles. Heuristic evaluation can be used to identify design issues and areas for improvement.
- A/B testing: A/B testing involves testing two versions of a system with different design elements. A/B testing can be used to determine which design elements are more effective.
Emerging Technologies
HCI is constantly evolving as new technologies emerge. Here are some emerging technologies in HCI:
- Virtual reality (VR): VR is a technology that immerses the user in a simulated environment. VR can be used for tasks such as training and education.
- Augmented reality (AR): AR is a technology that overlays digital information onto the user’s view of the real world. AR can be used for tasks such as navigation and product visualization.
- Natural user interfaces (NUI): NUI involves the use of natural gestures and speech to interact with technology. NUI can be used to create more intuitive and natural interactions with technology.
