This assembly describes the interaction of material elements that combine to give the walker knowledge about where to go and where she is. How does information pervade each compositional layer?
Thinking “assembly” perhaps allows the non-audio elements more weight than thinking “supporting materials.” For example, if I want a printed map to be part of the knowledge assembly, perhaps that gives me a prod to give the map a role that goes beyond just dots on a path where I should stop or arrows where I should turn. Perhaps it also holds an epigraph, or a letter, or a set of annotations, or spaces for the walker to write.
“Assembly” as a way to organize a work — a materials question. “Knowledge Assembly” as the way each material holds the needed information for the thing to happen.
