Pictorial menu for a digital camera. A user chooses an option from a menu by using an input device. Some input methods require linear navigation: the user must move a cursor or otherwise pass from one menu item to another until reaching the selection. On a computer terminal, a reverse video bar may serve as the cursor.
When a user clicks on a menu option the pull-down menu will appear. [3] [4] A menu has a visible title within the menu bar. Its contents are only revealed when the user selects it with a pointer. The user is then able to select the items within the pull-down menu. When the user clicks elsewhere the content of the menu will disappear. [5]
Text selection is associated with the cut, copy and paste operations and done with a cursor, caret navigation or touch.; Image editing applications can feature specialized graphical tools for the selection and modification of areas and shapes or to interact with colours, such as the magic wand selection tool, the lasso selection tool, the marquee selection (bounding box), or the color picker.
The pointer is an onscreen symbol that represents movement of a physical device that the user controls to select icons, data elements, etc. This style of system improves human–computer interaction (HCI) by emulating real-world interactions and providing greater ease of use for non-technical people. Because programs contained by a WIMP ...
Hyper-converged infrastructure (HCI) is a software-defined IT infrastructure that virtualizes all of the elements of conventional "hardware-defined" systems. HCI includes, at a minimum, virtualized computing (a hypervisor ), software-defined storage , and virtualized networking ( software-defined networking ).
Consider for example the process of deleting a file using a contextual menu. This assumes the existence of a mouse (input device), a screen (output device), and a piece of code that paints a menu and updates its selection (user feedback) and sends a command to the file system when the user clicks on the "delete" item (interpretation).
Human–Computer Interaction (HCI) – the intersection of computer science and behavioral sciences — this field involves the study, planning, and design of the interaction between people (users) and computers. Attention to human-machine interaction is important, because poorly designed human-machine interfaces can lead to many unexpected ...
In computer science, human–computer interaction, and interaction design, direct manipulation is an approach to interfaces which involves continuous representation of objects of interest together with rapid, reversible, and incremental actions and feedback. [1]
