Augmented Cognition: Attention and Uncertainty Representation Misha Pavel, Guoping Wang, Kehai Li Oregon Health and Science University pavel@ece.ogi.edu
Performance Constrained by Cognitive Limitations • Memory • Logical reasoning abilities • Illusions • Perceptual • Cognitive • Coordinate transformation • Ability to predict and anticipate states and actions • Information fusion • Decision – combining utilities, uncertainties • Abstract sources • Attentional limitations M. Pavel - PNNL March 8, 2002
Traditional Solutions • Traditional Solutions • Cognitive aids • Checklists • Mnemonic aids (Coffee cup) • Alerts • Training and rote learning • Divide and conquer – Team of operators/agents • Augmented Cognition • Model the cognitive limitation • Develop systems to amplify the ability M. Pavel - PNNL March 8, 2002
Principled Approach to Cognitive Amplification • Identify limitations • Quantify – Model the limitations • Develop amplifying principles • Information compression • re-mapping- visualization • Information fusion • Memory/context enhancemet • Measure amplification • Develop amplifying technology M.
