About

Contains 189 household tasks and 699 QA pairs across four memory levels (progress, anomalies, interventions, compound). It uses pre-recorded egocentric videos with fine-grained event annotations.

Evaluates next-action prediction and causal traceback. Best model accuracy is 61.2%, significantly below human performance (98.3%), highlighting difficulties in causal reasoning.
