11. A computer-readable storage medium, the computer-readable storage medium storing instructions that, when executed by a computer, cause the computer to perform operations comprising:
displaying to a user, image data including an object and a first visual stimulus corresponding to the object, the first visual stimulus having a characteristic modulation;
receiving neural signals of the user from a neural signal capture device;
determining a strength of components of the neural signals having a property associated with characteristic modulation of the first visual stimulus;
determining the object as an object of focus of the user based on the neural signals, the object of focus being inferred from a presence of the components of the neural signals having a property associated with the characteristic modulation of the visual stimulus; and
in response to determining the object as the object of focus, generating a second respective visual stimulus for the object of focus, the second respective visual stimulus including a background element having a low spatial frequency (LSF) that does not exceed 3 cycles per degree and a visual feedback element and a visual feedback element having a high spatial frequency (HSF) exceeding a threshold of 7 cycles per degree, the visual feedback element being displayed to the user with a visual effect selectively applied to the visual feedback element and not applied to the background element, the visual effect varying in accordance with the strength of the component having a property associated with the characteristic modulations of the first visual stimulus for the object of focus while the background component is not modulated.
