Previously, did you know what UI or User Interface is? The user interface is the point of contact between humans and computers and communicates within a device, including display screens, keyboards, mice, and desktop displays. User interfaces allow users to effectively control the computers or devices they interact with.<\/p>\n\n\n\n
Types of interaction with the user in the UI:<\/p>\n\n\n\n
Direct manipulation

Deficiency :
\u2013 This type of interface is complex and requires many facilities on the computer system, suitable for visual representation of an operation or object.<\/p>\n\n\n\n
Menu Selection
