A user can input spatial (i.e., continuous and multi-dimensional) data to a computer using a pointing device as an input interface. By moving a hand-held mouse or other similar device around the surface of the physical desktop and activating switches on the mouse, CAD systems and graphical user interfaces (GUI) enable the user to manage and send data to the computer using physical movements. The pointer (or cursor) and other visual modifications follow the motions of the pointing device on the screen. Drag and drop and point and click are frequent gestures.
What are point-and-draw devices?
Initially, text mode was the primary form of contact with computers. Users and computer designers soon discovered, however, that text-mode interaction is laborious, slow, and restricted in its application. Consequently, the concept of a new sort of user interface, known as a graphical user interface, was developed by computer designers (GUI). A GUI offers a screen with menus or graphic icons (little images on the screen), allowing a user to quickly select one to command a computer. GUI needs an input device that allows users to quickly point at and choose a graphic icon or menu item from a variety of possibilities shown on the screen in order to be used effectively. The keyboard gave rise to a variety of input devices, including the mouse, track ball, joystick, light pen, and touch screen, despite being useful, inconvenient, and inadequate for this need. Many of these tools, like the mouse and light pen, were later discovered by designers to be useful for efficiently drawing graphic components like lines, curves, and freehand shapes on the screen. These devices’ creators and users started referring to them as “point-and-draw” devices as a result of their new feature. They have improved the usability of computers and established them as useful tools for a variety of users, including kids, illiterate residents, and graphic designers. The following is a description of a few popular point-and-draw tools.
