Drag and drop is a user interface technique that involves holding down the primary mouse button and directing the mouse to a destination. It is an industry standard among operating systems and is used in various software applications, including email clients and games. Touch-screen devices also use this method for their user interface techniques. However, there are limitations, such as the need for both the original location and destination to be open during file transfers.
Drag and drop is one of many user interface techniques designed to move objects around a computer. The action of “dragging” involves holding down the primary mouse button (left click by default) and then directing the mouse to a destination. “Releasing,” on the other hand, involves releasing the primary mouse button on the target target. This technique allows for multiple applications in computer use, including repositioning and arranging files. Some programs use the drag-and-drop method to simplify some commands, such as entering data.
The technique replicates a natural human motion for moving objects. By treating the mouse pointer as a “hand”, users can grab, move and place various virtual objects. This intuitive design is an industry standard among operating systems, usually helping to make computer use more accessible to the average person.
Software programmers add drag and drop functionality to their applications for ease of use. For example, several email clients allow you to drag and drop file attachments into an outgoing message. This saves the user the time and effort usually reserved for locating and attaching the file via a separate dialog. The drag and drop technique is also used for various games, office programs and other software in which virtual objects are moved. With the development of HyperText Markup Language version 5 (HTML5), websites can include drag-and-drop functionality within their code, allowing for more user-friendly interfaces.
Many touch-screen devices use the method as a basis for their user interface techniques. Instead of tapping the screen multiple times to navigate the device, users can simply keep their fingers on the screen and “drag” to the desired destination. The “drop” stops the movement. Due to the small screen size on handheld devices, you may need to drag and drop multiple times before you get the desired result. This allows for faster use of the device and reduces screen wear.
However, there are some limitations to the drag and drop method. In transferring files, both the original location and the destination destination must be opened during the procedure. While this is often a minor issue, it is still possible for the destination to overlap the original location, making the new desired location inaccessible. The remedy for this problem is drag-and-drop itself; the destination simply needs to be dragged and dropped to an area of the screen away from the file’s original location. Other problems arise when designers tamper with the convention, as is the case with computer trackpads; instead of buttons, users often have to double-tap the pad before using drag-and-drop.
