We developed a foot\u2010pedal monitoring camera system that displays the pedal area on the endoscopic monitor, allowing operators to confirm pedal position without looking away from the procedural field. This study evaluated the effect of the system on foot\u2010pedal operation during simulated therapeutic endoscopy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This single\u2010center simulation study used a custom\u2010built simulator that displayed one of four commands on a monitor: cutting, coagulation, water jet, or injection. Participants responded by pressing the corresponding foot pedal. Each participant completed three sets of 20 commands under two conditions: with and without camera assistance. The primary outcome was participant\u2010level mean reaction time. Secondary outcomes included participant\u2010level median reaction time, incorrect pedal presses, and gaze shifts toward the foot pedals.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Eighteen endoscopists from 13 institutions completed all simulation tasks under both study conditions. Camera assistance significantly reduced the mean reaction time compared with the conventional condition (1190.4\u00a0ms vs. 1280.8\u00a0ms;\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.0024). Participant\u2010level median reaction times were also significantly shorter with camera assistance. In addition, camera assistance reduced incorrect pedal presses and gaze shifts.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The foot\u2010pedal monitoring camera improved the speed of pedal operation and reduced incorrect pedal presses and gaze shifts during simulated therapeutic endoscopy.
