Study Notes
Usability Overview
- Usability is a quality attribute that evaluates how easy user interfaces are to use, encompassing methods to enhance ease-of-use in design.
- Five key components define usability:
- Learnability: Ease of completing basic tasks upon first encounter with the design.
- Efficiency: Speed at which users perform tasks after learning the design.
- Memorability: Ability for users to regain proficiency after a period of non-use.
- Errors: Frequency and severity of errors made by users and recovery ease.
- Satisfaction: Overall pleasantness of the design experience.
User Interface Design Principles
- Flexibility and robustness are crucial design rules.
- Effective user interfaces accommodate both novice and expert users, validating diverse needs within design.
Utility, Usability, Likeability Distinction
- Utility: Refers to a product's ability to achieve specific goals or tasks.
- Usability: Related to the quality and efficiency measured by how well a product assists users in accomplishing their tasks.
- Likeability: Aesthetic appreciation that may not directly relate to usability or utility.
Key Usability Recommendations
- Include informative feedback that is meaningful, relevant, and clear throughout user interactions to enhance understanding of ongoing processes.
- Design dialogue sequences with a clear structure of beginning, middle, and end to prevent user uncertainty; outcomes of actions should be explicit.
- Focus on error prevention and handling by incorporating clear notifications and actionable hints to help users resolve issues quickly.
User Interface Features for Different User Types
- Advanced features beneficial for expert users include:
- Function keys
- Abbreviations
- Hidden commands
- Macro facilities
- Provide additional support for novice users, such as help menus to clarify functionalities.
