Study Notes
Human-Computer Interaction (HCI) Challenge
- HCI involves understanding users, their tasks, and their surrounding environment
- Involves gathering and analyzing user interface (GUI) requirements
- Includes designing, prototyping, and evaluating systems
The Goals of HCI
- Focus on developing or improving system safety, utility, effectiveness, efficiency, and usability
- Systems include computers
- Goal is to improve interactions with systems using computers
Usability
- A usable system is easy to learn, easy to use, efficient, effective, safe, and enjoyable to use
Bad User Interfaces
- Can be annoying, embarrassing, frustrating, or even deadly
- Increase mistakes in data entry and system operations
- Can make system functions inaccessible
- Can lead to system failure due to user rejection
Importance of HCI in the Context of the World Wide Web (WWW)
- Good user interfaces are not easy to create because of basic misconceptions
- Common misconceptions are that if developers or non-technical staff can use a system, everyone can
- People mistakenly believe that good user interfaces are based on common sense
- Another common misconception is that a usable system is achieved simply by following style guidelines
