Controls in the context of GUI (Graphical User Interface):
Controls refer to interactive elements such as buttons, checkboxes, text fields, sliders, and menus used in GUIs to enable user interaction with software applications. These controls provide a visual representation of available actions and options, allowing users to manipulate and navigate the interface easily. Effective design of controls is essential for enhancing user experience, ensuring usability, and minimizing cognitive load. By employing principles such as consistency, affordance, feedback, and responsiveness, designers can create intuitive and user-friendly GUIs that facilitate efficient interaction and task completion.

Voice User Interfaces (VUI):
Voice User Interfaces allow users to interact with computer systems using spoken commands or natural language input. VUIs leverage speech recognition technology to interpret and process user speech, enabling hands-free and eyes-free interaction. These interfaces are increasingly popular in applications like virtual assistants, smart home devices, and automotive systems, offering convenience, accessibility, and a more natural interaction paradigm compared to traditional graphical interfaces.

Hypermedia:
Hypermedia refers to digital content that includes hyperlinks, allowing users to navigate between different pieces of information or media elements non-linearly. Examples of hypermedia include hypertext documents, multimedia presentations, and interactive websites. Hypermedia systems facilitate flexible and dynamic navigation, enabling users to explore content in a non-linear and interactive manner. This enhances user engagement, information retrieval, and comprehension by providing contextual links and multimedia content that enriches the user experience.
