An underwater diving mask for use by a diver in an underwater diving
environment has a viewing portion defined by the diver's face and a lens,
a visual display device proximate the viewing portion to provide visual
images to the diver, a speaking chamber configured to sealing engage a
portion of the diver's mouth to permit the diver to speak, and a sound
transducer located proximal the speaking chamber. A computer system is
disposed in a portion of the mask and is operatively coupled to the sound
transducer and to the visual display device, where the computer system,
the viewing portion and the speaking chamber are sealing isolated from
the underwater diving environment. The computer system receives
electrical signals produced by the sound transducer and is configured to
recognize and identify the electrical signals as spoken words of the
diver, such that the identified spoken words provide input to the
computer to direct the computer system to provide visual images to the
visual display in response thereto, to facilitate hands-free operation of
the diver.
