Study Notes
Human Computer Interaction (HCI) - CSBP 316
- HCI is the study, design, construction, and implementation of human-centric interactive computer systems
- During its early years, HCI was known as man-machine studies.
- Computer-Human Interaction (CHI) is another term for HCI
- HCI is concerned with the communication between human users and computers.
What is HCI
- HCI is the communication between a human user and a software application or hardware device.
- The hardware device provides services via a computer program
- HCI is not just about computers, but includes many real-world examples like VCR's, wristwatches, phones, copiers, cars, plane cockpits, and air traffic control
Why HCI
- Systems fail due to inadequate requirements, lack of user participation, lack of resources, unrealistic expectations, changing specifications, and lack of planning. These failures represent 13%, 12%, 11%, 10%, 9%, and 8% respectively of the causes of system failure.
- Usable products are easy to learn, effective to use, enjoyable, and allow users to complete tasks safely, effectively, efficiently, and enjoyably
- A business perspective argues that employing people more productively and effectively is crucial, as people costs now outweigh hardware and software costs. Users expect easy-to-use systems. Poorly designed systems are generally not accepted.
- Human limitations and costly errors are key concerns in HCI
- Errors in critical systems can result in loss of time, money, lives, and morale.
User Experience (UX)
- UX refers to how a product behaves and is used in the real world.
- It's impossible to design user experience. Only a design for a user experience can be created.
- A meaningful UX creates joy, excitement, pleasure, and fun for users.
- A UX study investigates users and their needs within their context, focusing on the user at every stage of the design process.
- A positive user experience (UX) is one that is easy, not complicated
Usability
- Usability is the degree to which a software/application can be used by specified users to achieve quantified objectives with effectiveness, efficiency, and satisfaction.
- Important factors for a usable software system include:
- Ease of learning
- High speed of user task performance
- Low user error rate
- Subjective user satisfaction
- User retention over time
- Six key goals for usability include:
- Effectiveness
- Efficiency
- Safety
- Utility
- Learnability
- Memorability
Improving Interfaces
- Improve interfaces by educating software professionals on User-Centered Design (UCD)
- Incorporate UI (User Interface) design methods and techniques into standard software development methodologies.
