An interface between a surgeon and an automated assistant, wherein the interface comprises at least one array comprising N RF transmitters and at least one RF receiver provided with at least two directional antenna, as well as means for attaching said RF transmitter array to at least one surgical tool. Furthermore, the interface comprises a computerized operating system adapted to record the received signal strength (RSS) received by each antenna of said one RF receiver and to calculate therefrom the position of each of said N RF transmitters, and is further adapted to provide automatically the results of said calculation to said surgeon. The computerized operating system is adapted to calculate at least one of the parameters chosen from the group consisting of: (a) the angle from which the signal had been received (b) the spatial location of said at least one surgical tool (c) the path of said at least one surgical tool (d) the spatial location of the point of insertion of said at least one surgical tool into the body of a patient (e) the spatial location of the tip of said at least one surgical tool (f) matching each RF transmitter code with each calculated spatial location of said at least one surgical tool and/or said tip of said at least one surgical tool. The computerized operating system performs said calculations and provides automatically the results of said calculations to the human operator of said interface. Furthermore, said calculation performed by said computerized operating system is a non-triangulation calculation. A method for locating and maneuvering a laparoscopic tool with the interface is also disclosed.
