A “cogni-digital interface” is the part of a system that enables the interspheral exchange of information between the cognisphere and the digital info sphere.

The term “cogni-digital interface” was formed as part of the terminology of the “Digital Era Framework”. This reference framework defines four spheres according to the type of information manifestation, which can be used to classify interfaces: The infosphere, which consists of the analog infosphere and the digital infosphere, the cognisphere and the entisphere. If an interface allows the exchange of information between the cognisphere and the digital infosphere, the term “cogni-digital interface” can be used.

The term “cyber-cognitive interface” can serve as a synonym.
