Sound amplification/noise cancelling based on eye focus detection

In a noisy environment, distinction of sounds can be difficult when trying to focus on a single sound (e.g. a particular voice) from a number of audible sounds. This is particularly true for those who have hearing difficulties requiring use of a hearing aid, which typically are not able to distinguish between sounds and will amplify background noise along with the sound of interest.

    This invention aims to determine the focus of a person based on their eye focus and use that to amplify a specific sound.

    This invention claims a novel combination of existing technologies to create a method for sound amplification/noise cancelling, using the following methods:

     - the detection of eye gaze and focal depth by eye position tracking and eye vergence. This is known technology and not claimed to be part of this submission's novelty.

     - the detection of sound source locations by use of multiple sound receivers. This is known technology and not claimed to be part of this submission's novelty.

     - The correlation of the eye gaze and focal depth with the set of sound source locations to then apply amplification to that specific sound and apply noise cancelling to all other sound sources. This correlation of data to determine how to apply sound amplification/cancelling is the novel part of our invention.

Features:
the correlation of eye gaze/focus data with sound source locations to determine how to apply sound amplification/cancelling is novel.
the application of eye gaze/focus to select a specific sound to amplify and the application of noise cancelling to other sources
This invention has applications not only for those with hearing difficulties, but could more generally be a useful feature of wearable tech such as augmented reality (AR) or VR devices.
