A system for operating a controlled device, comprising: a module including a sensor and a moveable actuator, the sensor configured to produce output signals according to a relative position of the actuator, wherein the moveable actuator has a defined range of travel in relation to the sensor, between a fully extended position, in which the moveable actuator is biased when not acted upon by any external forces, and a fully seated position, the module is configured to generate an initial signal as a result of partial compressing of the moveable actuator to a point at which the moveable actuator is positioned at a location between its fully extended position and fully seated position when a wearer dons the system so as to provide for subsequent adequate movement of the moveable actuator with respect to the sensor in order to generate output signals recognizable as commands for the controlled device upon the position of the moveable actuator being affected by volitional actions of the wearer, and the module is adapted to be worn on a person of the wearer by attachment to a headband of an augmented reality, AR, or virtual reality, VR, headset or a temple piece of a pair of spectacles; a controller coupled to receive the output signals from the sensor and including a processor and a memory coupled to the processor, the memory storing processor-executable instructions that, when executed by the processor, cause the processor to receive and evaluate the output signals of the sensor to determine whether or not the output signals of the sensor represent a command for the controlled device by assessing the output signals of the sensor for a signal pattern indicative of one or more volitional actions of the wearer of the module, and when the processor determines that the output signals of the sensor represent the command for the controlled device, then decoding the command for the controlled device and transmitting a control signal to the controlled device via a communication element, otherwise if the processor determines that the output signals of the sensor do not represent the command, then not transmitting the control signal and proceeding to evaluate further output signals of the sensor; and the communication element communicatively coupled to receive the control signal from the processor and to transmit the control signal to the controlled device. a module including a sensor and a moveable actuator, the sensor configured to produce output signals according to a relative position of the actuator, wherein the moveable actuator has a defined range of travel in relation to the sensor, between a fully extended position, in which the moveable actuator is biased when not acted upon by any external forces, and a fully seated position, the module is configured to generate an initial signal as a result of partial compressing of the moveable actuator to a point at which the moveable actuator is positioned at a location between its fully extended position and fully seated position when a wearer dons the system so as to provide for subsequent adequate movement of the moveable actuator with respect to the sensor in order to generate output signals recognizable as commands for the controlled device upon the position of the moveable actuator being affected by volitional actions of the wearer, and the module is adapted to be worn on a person of the wearer by attachment to a headband of an augmented reality, AR, or virtual reality, VR, headset or a temple piece of a pair of spectacles; a controller coupled to receive the output signals from the sensor and including a processor and a memory coupled to the processor, the memory storing processor-executable instructions that, when executed by the processor, cause the processor to receive and evaluate the output signals of the sensor to determine whether or not the output signals of the sensor represent a command for the controlled device by assessing the output signals of the sensor for a signal pattern indicative of one or more volitional actions of the wearer of the module, and when the processor determines that the output signals of the sensor represent the command for the controlled device, then decoding the command for the controlled device and transmitting a control signal to the controlled device via a communication element, otherwise if the processor determines that the output signals of the sensor do not represent the command, then not transmitting the control signal and proceeding to evaluate further output signals of the sensor; and the communication element communicatively coupled to receive the control signal from the processor and to transmit the control signal to the controlled device.
