Abstract

Generally, a method performed by one or more processing devices includes generating a graphical user interface that when rendered on a display of the one or more processing devices renders a visual representation of an environment and a visual representation of an object in the environment; retrieving an auditory stimulus with one or more auditory attributes indicative of a location of a virtual target in the environment; receiving information specifying movement of the object in the environment; determining, based on the movement of the object, a proximity of the object to the virtual target; adjusting, based on the proximity, one or more values of the one or more auditory attributes of the auditory stimulus; and causing the one or more processing devices to play the auditory stimulus using the adjusted one or more values.

First claim

What is claimed is:

1. A method performed by one or more processing devices, the method comprising:
starting a program;
generating data for a graphical user interface that when rendered on a display of a display device renders a visual representation of an object;
identifying an auditory stimulus signal indicative of a location of a virtual target in the graphical user interface;
receiving data representing a location of the visual representation of the object in the graphical user interface;
intermittently determining whether a location of the visual representation of the object in the graphical user interface corresponds to the location of the virtual target until the location of the visual representation of the object in the graphical user interface corresponds to the location of the virtual target;
while the location of the visual representation of the object in the graphical user interface does not correspond to the location of the virtual target,
determining, based on processing of the data representing the location of the visual representation of the object, a proximity of the visual representation of the object to the virtual target in the graphical user interface;
intermittently modifying, based on the proximity, the auditory stimulus signal by modifying a frequency of the auditory stimulus signal, a signal-to-noise ratio of the auditory stimulus signal, a sound level of the auditory stimulus signal, a binaural characteristic of the auditory stimulus signal, or a modulation of a sound envelope of the auditory stimulus signal; and
causing one or more speaker devices to play the modified auditory stimulus signal;

when the location of the visual representation of the object in the graphical user interface corresponds to the location of the virtual target,
completing the program.

2. The method of claim 1 , further comprising:
detecting, following play of the auditory stimulus, that a location of the visual representation of the object in the graphical user interface corresponds to the location of the virtual target in the graphical user interface.

3. The method of claim 1 , wherein the actions of receiving, determining, and intermittently modifying are repeated until a location of the visual representation of the object in the graphical user interface corresponds to the location of the virtual target in the graphical user interface.

4. The method of claim 1 , further comprising:
causing a diagnostic auditory signal to be played on the one or more speaker devices;
receiving information indicative of a response of a user to the diagnostic auditory signal;
determining, at least partly based on the received information, auditory dysfunction in one or more types of auditory perception of the user;
determining, based on the determined auditory dysfunction, the frequency; and
determining, based on one or more amounts of auditory dysfunction in the one or more types of auditory perception, one or more ranges of values for the frequency.

5. The method of claim 4 , wherein the one or more ranges of values comprise one or more ranges of first values, and wherein the method further comprises:
detecting a decrease in auditory dysfunction of the user; and
updating, based on the detected decrease, the first values to second values, with the second values promoting an additional decrease in auditory dysfunction of the user.

6. The method of claim 1 , further comprising:
determining, based on the proximity, that the visual representation of the object has moved towards the virtual target; and
generating a notification that the visual representation of the object has moved towards the virtual target.

7. The method of claim 1 , further comprising:
determining, based on the proximity, that the visual representation of the object has moved away from the virtual target; and
generating a notification that the visual representation of the object has moved away from the virtual target.

8. The method of claim 1 , wherein the auditory stimulus promotes auditory rehabilitation in a user by training the user to locate the virtual target in the graphical user interface based on a perception of the user of the frequency.

9. One or more machine-readable media configured to store instructions that are executable by one or more processing devices to perform operations comprising:
starting a program;
generating data for a graphical user interface that when rendered on a display of a display device renders a visual representation of an object;
identifying an auditory stimulus signal indicative of a location of a virtual target in the graphical user interface;
receiving data representing a location of the visual representation of the object in the graphical user interface;
intermittently determining whether a location of the visual representation of the object in the graphical user interface corresponds to the location of the virtual target until the location of the visual representation of the object in the graphical user interface corresponds to the location of the virtual target;
while the location of the visual representation of the object in the graphical user interface does not correspond to the location of the virtual target,
determining, based on processing of the data representing the location of the visual representation of the object, a proximity of the visual representation of the object to the virtual target in the graphical user interface;
intermittently modifying, based on the proximity, the auditory stimulus signal by modifying a frequency of the auditory stimulus signal, a signal-to-noise ratio of the auditory stimulus signal, a sound level of the auditory stimulus signal, a binaural characteristic of the auditory stimulus signal, or a modulation of a sound envelope of the auditory stimulus signal; and
causing one or more speaker devices to play the modified auditory stimulus signal;

when the location of the visual representation of the object in the graphical user interface corresponds to the location of the virtual target,
completing the program.

10. The one or more machine-readable media of claim 9 , wherein the operations further comprise:
detecting, following play of the auditory stimulus, that a location of the visual representation of the object in the graphical user interface corresponds to the location of the virtual target in the graphical user interface.

11. The one or more machine-readable media of claim 9 , wherein the actions of receiving, determining, and intermittently modifying are repeated until a location of the visual representation of the object in the graphical user interface corresponds to the location of the virtual target in the graphical user interface.

12. The one or more machine-readable media of claim 9 , wherein the operations further comprise:
causing a diagnostic auditory signal to be played on the one or more speaker devices;
receiving information indicative of a response of a user to the diagnostic auditory signal;
determining, at least partly based on the received information, auditory dysfunction in one or more types of auditory perception of the user;
determining, based on the determined auditory dysfunction, the frequency; and
determining, based on one or more amounts of auditory dysfunction in the one or more types of auditory perception, one or more ranges of values for the frequency.

13. The one or more machine-readable media of claim 12 , wherein the one or more ranges of values comprise one or more ranges of first values, and wherein the operations further comprise:
detecting a decrease in auditory dysfunction of the user; and
updating, based on the detected decrease
