The tight interdependencies of information, technology, and speech become most apparent in moments of breakdown and failure. Meetings without properly formatted slides cannot take place. Computer failures prevent speakers from talking about what they want to talk about. Students refuse to recognize the legitimacy of lecture content unaccompanied by slides. Even within functioning presentations, subtle cues signal that visuals and speech are bound into a common rhetorical object. Sociologist Hubert Knoblauch has focused on gestural coordinating of verbal content with on-screen images. Whether by hand, mouse, or pointer, the indexical move signifies that pictures do not stand alone.33 The speaker, decentered by the screen, enacts a “multimodal discourse” characterized by “two paradoxical patterns in discourse structure, a linear pattern in time, a sequential rhythm to discourse, and a non-linear pattern in space, a constellation of signs and symbols in three-dimensional space.”34 Multimodal discourse requires choreography, compositionality, ways of deciding how meaning ought to emerge from different channels, how they stand in relation, how audiences experience gestalt. There is a tremendous dependence upon not just knowledge production but also knowledge performance, or virtuosity.
