What are the different interaction styles in HCI?

The different interaction styles in HCI (Human-Computer Interaction) include:

1. Command Line Interface (CLI): Users interact with the computer system by typing commands in a specific syntax. It requires users to have knowledge of specific commands and their syntax.

2. Graphical User Interface (GUI): Users interact with the computer system through visual elements such as icons, menus, and buttons. It provides a more intuitive and user-friendly way of interacting with the system.

3. Menu-driven Interface: Users interact with the computer system by selecting options from a predefined menu. It simplifies the interaction process by presenting a limited set of choices.

4. Form-based Interface: Users interact with the computer system by filling out forms or entering data into predefined fields. It is commonly used for data entry tasks and online forms.

5. Natural Language Interface: Users interact with the computer system using natural language, such as spoken or written sentences. It aims to mimic human conversation and provide a more natural and conversational interaction experience.

6. Gesture-based Interface: Users interact with the computer system through gestures, such as swiping, tapping, or pinching on touchscreens or motion sensors. It is commonly used in mobile devices and virtual reality systems.

7. Tangible User Interface (TUI): Users interact with the computer system through physical objects or manipulatives. It combines physical and digital elements to provide a more tangible and interactive experience.

8. Voice User Interface (VUI): Users interact with the computer system using voice commands or speech recognition. It is commonly used in voice assistants and automated phone systems.

These interaction styles can vary in their complexity, ease of use, and suitability for different tasks and user preferences.
