Abstract
A user interface device provides secure access to equipment. An audio reception device is adapted to receive an audio input comprising background noise and to receive an audio user code from a user. A user input device receives a manual input comprising a manual user code from the user. A control unit stores one or more target user codes and receives an audio input and determines a noise level of the background noise. An instruction message is generated to inform the user to enter the manual user code in response to the noise level of the background noise exceeding a predetermined threshold level. An output device provides the instruction message to the user. A control unit provides secure access to the equipment in response to at least one of the audio user code and the manual user code.
