Abstract: A computer-implemented method of controlling operator interaction with one or more operator devices is disclosed. The one or more operator devices comprise one or more analyzing devices configured to analyze biological samples. The method comprises, responsive to any of the one or more analyzing devices being triggered by the operator to perform an analysis of a sample, acquiring—in association with an identifier of the operator—information regarding any sample associated handling error detected by the triggered analyzing device. The method also comprises dynamically updating handling error data associated with the identifier of the operator based on the information regarding detected handling errors, and controlling—for the identifier of the operator—interaction with at least one of the one or more operator devices based on the handling error data associated with the identifier of the operator. A computer-implemented method of an analyzing device is also disclosed.
