- 2. Plan • User interface, as a means of human-computer interaction. Usability of Interfaces. • Types of interfaces: command line interface, text interface, graphical interface, natural-language user interface • Mental characteristics of the user. • Stages of user interface development. • Types of interface testing (user testing). • Prospects for the development of interfaces.
- 3. User interface, as a means of human- computer interaction Human–computer interaction (HCI) researches the design and use of computer technology, focused on the interfaces between people and computers.
- 4. USER INTERFACE The user interface (UI), in the industrial design field of human– computer interaction, is the space where interactions between humans and machines occur.
- 5. Usability
- 6. Usability of interface Usability is the degree to which a software can be used by specified consumers to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use. Usability of interface consists of Learnability Efficiency Memorability Errors Satisfaction
- 7. Types of interfaces • command line interface • text interface • graphical interface • natural-language user interface
- 8. Command-line interface A command-line interface is a means of interacting with a computer program where the user (or client) issues commands to the program in the form of successive lines of text (command lines).
- 9. Text-based user interface Text-based user interface (TUI) is a user interface where by all output is presented in the form of text.
- 10. GRAPHICAL USER INTERFACE The graphical user interface (GUI ) is a type of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, instead of text-based user interfaces, typed command labels or text navigation.

- 12. Natural-language user interface • Natural-language user interface (LUI or NLUI) is a type of computer human interface where linguistic phenomena such as verbs, phrases and clauses act as UI controls for creating, selecting and modifying data in software applications.
- 13. mental characteristics of the user A mental model is a person’s intuitive understanding of how something functions based on his or her past encounters, exposure to information, and sound judgment.

- 16. Mental Models and User Experience A mental model is a person’s intuitive understanding of how something functions based on his or her past encounters, exposure to information, and sound judgment.
- 17. How People Form Mental Models Observation Observation is a crucial method of getting answers concerning people’s responses to their general surroundings. As individuals, we are well equipped to pick up detailed data about our environs through our senses.
- 18. How People Form Mental Models Immersive Experience An immersive experience is one in which a user is totally caught up in a system. If the experience is a positive one, the user’s satisfaction may reach new heights. Immersive experiences stimulate our senses.
- 19. How Understanding Mental Models Influences User-Interface Design Don Norman discusses mental models in his article “Some Observations on Mental Models,” in which he also considers conceptual models and theoretical models. Norman says, “Conceptual models are devised as tools for the understanding or teaching of physical systems. Mental models are what people really have in their heads and what guides their use of things.”
- 20. How People Form Mental Models Culture People belonging to different cultures often have different mental models…. Culture plays a vital role in shaping human perceptions. Because people belonging to different cultures often have different mental models, the internationalization and localization of Web experiences that must address these cultural intricacies has always been challenging for designers.
- 21. Tips from free designers • Try to learn something about users • Come up with your own characters • Brainstorm • Use common design patterns • Remember that we are all human, and we are all United by the same psychological principles

- 30. What is Interface Testing? Interface Testing is the testing done on AUT which actually verifies whether the communication between two different software systems are done correctly.
- 31. Why to do Interface Testing Interface Testing is done • To ensure that end-users or customer should not encounter any problem when using a particular software product • To identify which application areas are usually accessed by end-users and to check its user-friendliness as well. • To verify security requirements while communication propagates between the systems • To check if solution is capable to handle network failures between application server and website
- 32. Types of Interface Testing Вставить описание для текущего This include testing each system individually. For example, billing system and inventory management system for retail store should be able to operate separately. This is considered when testing include date, month and day reversed A high-volume interface may require more Load Testing than a low-volume interface, depending on the interface engine and connectivity infrastructure Individual systems Edge cases -unexpected values Performance, load, and network testing It ensures that the interface engine handles your standard workflows as expected.
