Study Notes
Human-Interface Objects (HIOs)
- HIOs are objects on a screen that users can manipulate, such as documents, buttons, menus, folders, and icons.
- HIOs are commonly used in most applications, including the Microsoft Office Suite.
- A characteristic of HIOs is affordance, which means that their appearance suggests their function.
- For example, a control that looks like a steering wheel suggests that it is used for turning.
Visibility and Feedback
- Visibility means that a control is visible, and users know it is available.
- Feedback is a visual or audio response by the system in response to user action.
- Feedback provides users with a sense of confirmation and indicates that the system is responsive and functioning correctly.
- Lack of feedback leaves users wondering if a command or input was recognized or if the system is malfunctioning.
Consistency
- Consistency is essential in various aspects of the user interface and the application.
- Users expect consistency across different screens of an application and across applications.
- Consistency significantly affects the effectiveness of the user experience.
Readability and Navigation
- Readability and navigation are crucial, but can be challenging to support, especially on small mobile devices.
- Large desktop screens usually have good readability, but small mobile devices often have readability problems.
- Large desktop screens have space for navigation clues, while small mobile devices may require hidden or partially hidden navigation tools.
