Study Notes
Human-Computer Interaction (HCI)
- HCI is a discipline concerned with the design, evaluation, and implementation of interactive computing systems for human use.
- It involves the study of the major phenomena surrounding them.
- HCI is important because it helps to create usable systems that are easy to interact with.
Factors Influencing HCI
Computer
- Different devices such as smartphones, desktops, and kiosks
- Capabilities and limitations of computing devices including processing power.
- Operating systems play a vital role in the design and functionality of user interfaces.
- Rapidly changing interface technology requires ongoing adaptation.
Human
- Different users bring a wide range of abilities, skills, and experiences.
- Users have different conceptions and mental models of how technology should function.
- Learning styles, knowledge retention, and skill levels vary among users.
- Social aspects, like cultural and national differences, influence user interface design.
- The digital divide refers to the gap in access to technology and related skills, which is another crucial factor in HCI.
User Interface (UI)
- The UI is the part of an application that allows users to interact with computers and the interface to communicate results back to the user.
- HCI encompasses the design, implementation, and evaluation of UIs.
Different Perspectives of HCI
- Task: How users complete tasks and interact with systems.
- Design: The process of creating and improving the user interface.
- Technology: The hardware and software used by the system.
- Human: The users’ mental models, cognitive abilities, and overall experience.
Good Design
- User-Centered Design (UCD) is a process and outcome of designing with the user's needs in mind.
Specific User Interface Design Principles
- If elements are replicated across multiple screens, they should be placed in consistent positions for improved user experience.
- Using all uppercase letters is difficult to read and can be perceived as shouting.
Cost of Bad Design
- Poor interface design can lead to frustration and wasted time, and can even have serious consequences in critical applications.
- Frustration can be experienced when users encounter cryptic icons, unnecessarily deep menus, or an excessive amount of pop-up dialog boxes.
