The MHEG-5 mix-in class Interactible groups some functionality associated with user interface-related objects (Slider, HyperText, EntryField, Buttons).

These objects can all be highlighted (by setting their HighlightStatus to True).

They also have the attribute InteractionStatus, which, when set to true, allows the object to interact directly with the user, thus bypassing the normal processing of UserInput events by the MHEG-5 engine.

Exactly how an Interactible reacts when its InteractionStatus is true is implementation-specific.

As an example, the way that a user enters characters in an EntryField can be implemented in different ways in different MHEG-5 engines.

At most one Interactible at a time can have its InteractionStatus set to True. Interactibles
