To achieve effective communication in the process of human-machine interaction, polymodal user interfaces are used. The article classifies typical interface elements corresponding to various communication channels in order to identify the composition of elements for the implementation of a polymodal interface that provides the ability to display the user's professional activities. Taking into account the above classification, a model of the interface structure is proposed that reflects the logic of the user's work.

The article discusses the methodology for organizing the use of the user interface design module by the end user on their own. One of the main stages of the methodology is the user's description of his professional activity. To implement this stage, the functional structure of the module for generating a description of the activity by the user, a description of its components (submodules) and the composition of the main algorithms are given.
