Comparison of Four Primary Methods for Coordinating the Interruption of People in Human-Computer Interaction
- Daniel C. McFarlane
- Human-Computer Interaction
A laboratoty experiment was used to evaluate the effects of interaction frequency on computer-mediated groups using a Group Support System to perfom an idea-generation task Group interaction is defined here as the length of time group members are allowed to form and input their connibutions and the related rate at which group members exchange their contributions. We found that frequently interacting groups and nominal groups outperfomzed infrequently interacting groups and individuals, but that frequently interacting groups felt more interrupted, less able to concentrate, and more hum’ed.
