1. A method for use with a multimodal computing device capable of displaying visual messages comprising the steps of:

  • providing a multimodal interface that includes an audio interface and a visual interface;

    sampling for a background noise to produce a sampled noise level;

    comparing the sampled noise level with a first predetermined noise threshold;

    in response to determining that the sampled noise level is above the first predetermined noise threshold, enabling interaction with the user via the visual interface by providing at least one visual prompt for user input;

    comparing the sampled noise level with a second predetermined noise threshold; and

    in response to determining that the sampled noise level is below the second predetermined noise threshold;

    disabling interaction with the user via the audio interface;

    enabling interaction with the user via the visual interface;

    determining whether earphones are connected to the multimodal computing device; and

    when it is determined that earphones are connected to the multimodal computing device, re-enabling interaction with the user via the audio interface.
