An Analysis of Graphic Use in Audio-graphic Teleconferences

This field study focused on the use of graphics during audio-graphics teleconferences. Variables measured were receivers' interest, perceived levels of comprehension and retention, as well as information clarity. Significant differences existed among telecon ferences which had no graphics, conferences in which the graphics did not directly complement the audio message, and those conferences in which the graphics directly complemented audio messages. A higher number of graphics complementing audio messages did not result in significant improvements. Individual differences were not an interacting effect. The perceived quality of the graphics was significantly related to the perceived effectiveness of the teleconference.
