An ice auger shroud system for directing debris produced during the drilling of an ice hole in a controlled direction from the operator. The recognition system is configured to recognize actions taken by a user while the user operates the user interface system and to selectively instruct the control system to cause the sensor-actuator system to perform, andor simulate, one of an automatic step, a semi-automatic step or direct step of the multi-step task based on the recognized actions and a task model of the multi-step task. When the scan signal is de-asserted, the switch unit decouples one of the sourcesdrains of the second driving transistor from the firstsecond sourcedrain of the first driving transistor, and decouples the gate from the second sourcedrain of the first driving transistor. The bottom end of the supporting structure fixedly connects to the bottom end of the corresponding side of the transition section. Thus, if the map information is unwritable, alterations to the map information can be made to it by means of editing information so that the user can be provided with appropriate guidance.
