The Input Field component allows you to create and edit variables. Variables are elements that can assume a certain value. A variable consists of a key and a value. The key is the ‘label’ of the variable, and is used to identify the variable. The value is the merit that is given to a variable. This value (or merit) can consist of a series of letters or numbers. Variables that are acquired through the Input Field component can be deployed for multiple purposes. This component is frequently used for textual personalization. In this case, the viewer will for example be asked to fill in his or her first name. This name will then be displayed (as a variable) on a later moment in the video
