Embodiments described herein provide various examples of a surgical procedure analysis system for extracting an actual procedure duration that involves actual surgical tool-tissue interactions from a total procedure duration of a surgical procedure. In one aspect, the process for generating the haptic feedback signal includes the steps of: obtaining the total procedure duration of the surgical procedure； receiving a set of operating room (OR) data from a set of OR data sources collected during the surgical procedure； analyzing the set of OR data to detect a set of non-surgical events during the surgical procedure that do not involve surgical tool-tissue interactions； extracting a set of durations corresponding to the set of events； and determining the actual procedure duration by subtracting the combined set of durations corresponding to the set of events from the total procedure duration.
