A Virtual Protocol Model for Computer-Human Interaction

Resumé

A model of computer-human interaction is presented, viewing the interaction as a hierarchy of virtual protocol dialogues.

Each virtual protocol realizes the dialogue on the level above itself and is in turn supported by a lower level protocol.

This model is inspired by the OSI-model for computer networks from the International Standards Organization.

The virtual dialogue approach enables the separation of the technical features of new devices (e.g. a mouse or a graphical display) from the conceptual features (e.g. menus or windows).

Also, it is possible to analyze error messages and other feedback as part of the different protocols.
