A hearing aid and related systems and methods. In one implementation, a hearing aid system may selectively amplify sounds emanating from a detected look direction of a user of the hearing aid system. The system may include a wearable camera configured to capture a plurality of images from an environment of the user; at least one microphone configured to capture sounds from an environment of the user; and at least one processor programmed to receive the plurality of images captured by the camera, receive audio signals representative of sounds received by the at least one microphone from the environment of the user, determine a look direction for the user based on analysis of at least one of the plurality of images, cause selective conditioning of at least one audio signal received by the at least one microphone from a region associated with the look direction of the user, and cause transmission of the at least one conditioned audio signal to a hearing interface device configured to provide sound to an ear of the user.
