Devices, systems, and techniques for mitigating error from gesture input are disclosed. A system may receive an indication of a first gesture input, determine that the first gesture input is an indicator gesture input, and, responsive to the determination that the first gesture input is the indicator gesture input, enter a gesture control mode during which the system is configured to control one or more actions related to a medical procedure. Only during the gesture control mode, the system may receive an indication of a second gesture input associated with the medical procedure and, responsive to receiving the indication of the second gesture input, control, based on the second gesture input, at least a portion of the medical procedure. Additionally, or alternatively, the system may employ other error mitigation techniques for gesture input related to medical procedures.
