Abstract
Research has shown that trust and perceived reliability are key factors in whether a relationship will develop between humans and automation. Presenting automation reliability and automation algorithms are ways to potentially improve this relationship. To explore this question, an experiment was conducted in which an automated decision aid presented suggestions to participants while they managed a simulated city. Based on condition, the decision aid's algorithm was presented to participants in a textual or graphical (diagrammatic) format or not shown at all. Results showed that presenting the decision aid's algorithm, regardless of modality (i.e., textual or graphical) had a direct impact on reported trust and usage. Algorithm presentation also had an effect on both perception of the automation and on human performance. Additional results and implications are discussed.
