Augmented Cognition: Attention and Uncertainty Representation Misha Pavel, Guoping Wang, Kehai Li Oregon Health and Science University pavel@ece. ogi. edu M. Pavel - PNNL March 8, 2002
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 2/28/2021 2
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 2/28/2021 3
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.
