Apex automates a complex but powerful and economically valuable process for predicting human performance at human-computer interaction tasks, called CPM-GOMS (Cognitive, Perceptual, and Motor - Goals, Operators, Methods, and Selection). CPM-GOMS is a HCI (Human Computer Interaction) modeling technique that combines hierarchical tak decomposition with a resource architecture. CPM-GOMS has been shown to be successful at accurately predicting average durations of brief, routine tasks.
