1. A system for commanding technical control operations and/or for commanding execution of technical functions, said system having an input device comprising a force-torque sensor manually operated by a user interface and measuring linear displacements and/or rotary deflections and converting said displacements and/or deflections into a corresponding pair of force-torque vector signals being composed of a force vector signal and a torque vector signal, respectively, said user interface of said input device having at least one defined area assigned to a certain object to enter a pressure pulse which triggers a special switching operation and corresponds to pulse-shaped displacements and/or deflections of said user interface, said input device including a device evaluating and identifying such a pressure pulse by checking the pair of force-torque vector signals measured by said force-torque sensor in view of being within a predefined pressure pulse tolerance range and triggering said switching operation when the pair of force-torque vector signals is within the predefined pressure pulse tolerance range.
