What essential feature differentiates a HyperDoc from a standard document?

A HyperDoc is defined primarily by its ability to integrate linked resources within a single document, transforming it into an interactive learning experience. This essential feature allows educators to compile various multimedia elements such as videos, websites, and interactive tools that students can use as they engage with the content. The links within a HyperDoc facilitate a more connected and explorative approach to learning, enabling students to access additional information and resources seamlessly.

While visual aesthetics, printed materials, and offline accessibility can enhance the user experience, they are not fundamental to the definition of a HyperDoc. Visual aesthetics may make a document more appealing, but a standard document can also be visually appealing without being a HyperDoc. Printed materials do not leverage the interactive nature of a HyperDoc, which is reliant on digital connectivity, and offline accessibility pertains to how a document can be used without an internet connection, but it does not define the HyperDoc's primary function of linking resources. Thus, the integration of linked resources is what distinctly characterizes a HyperDoc and sets it apart from standard documents.
