1. A method of providing visual guidance for operating a surgical arm according to a pre-determined surgical approach, the surgical arm comprising a first interface configured to receive a device for performing or assisting a surgical procedure, multiple adjustment members configured to adjust the surgical arm relative to different adjustment axes, and at least two operating members configured to operate different ones of the adjustment members, wherein the operating members are marked with different visual codings, the method comprising the steps of:
determining at least one of a current position and a current orientation of the first interface or a device received by the first interface;
determining, based on the pre-determined surgical approach, at least one of a target position and a target orientation of the interface or the device;
based on a difference between at least one of the current and target positions and the current and target orientations, determining that an adjustment of the surgical arm is required relative to at least one of the adjustment axes; and
triggering a display of the visual coding associated with one of the at least two operating members that is associated with the at least one adjustment axis so as to provide visual guidance,
wherein the visual guidance comprises the display of the visual coding in combination with an indication of an amount by which the associated operating member is to be operated.
