Abstract

An illustrative system includes a brain interface system configured to be worn by a user and to output brain activity data representative of brain activity of the user while the user concurrently plays an electronic game and a computing device configured to obtain the brain activity data and modify, based on the brain activity data, an attribute of the electronic game.

First claim

What is claimed is:

1. A system comprising:
a brain interface system configured to be worn by a user and to output brain activity data representative of brain activity of the user while the user concurrently plays an electronic game; and
a computing device configured to
obtain the brain activity data, and
modify, based on the brain activity data, an attribute of the electronic game;

wherein the brain interface system comprises an optical measurement system configured to perform optical-based brain data acquisition operations, the brain activity data based on the optical-based brain data acquisition operations, the optical measurement system comprising:
a wearable assembly configured to be worn by the user and comprising:
a first slot surrounded by a first wall;
a second slot surrounded by a second wall;
a first module configured to be inserted into the first slot, the first module comprising a first light source configured to emit first light directed at a brain of the user and a first set of detectors configured to detect first arrival times for photons of the first light after the first light is scattered by the brain, the brain activity data based on the first arrival times; and
a second module configured to be inserted into the second slot, the second module comprising a second light source configured to emit second light directed at the brain and a second set of detectors configured to detect second arrival times for photons of the second light after the second light is scattered by the brain, the brain activity data further based on the second arrival times;

wherein a positioning of the first and second modules in the first and second slots is configured to cause a detector included in the first set of detectors of the first module to further detect third arrival times for photons of the second light after the second light is scattered by the brain, the brain activity further based on the third arrival times.

2. The system of claim 1 , wherein the positioning of the first and second modules in the first and second slots is further configured to cause a detector included in the second set of detectors of the second module to further detect fourth arrival times for photons of the first light after the first light is scattered by the brain, the brain activity further based on the fourth arrival times.

3. The system of claim 1 , wherein the first and second modules are configured to be interchangeably inserted into the first and second slots to acquire the brain activity data.

4. The system of claim 3 , wherein the detectors each comprise a plurality of single-photon avalanche diode (SPAD) circuits.

5. The system of claim 1 , wherein the brain interface system is further configured to perform electrical-based brain data acquisition operations, the brain activity data further based on the electrical-based brain data acquisition operations.

6. The system of claim 5 , wherein the brain interface system further comprises:
a plurality of electrodes configured to be external to the user and detect electrical activity of the brain, the brain activity further based on the electrical activity.

7. The system of claim 6 , wherein the plurality of electrodes comprises a first electrode on a surface of the first module and a second electrode on a surface of the second module.

8. The system of claim 7 , wherein the first electrode surrounds the first light source on the surface of the first module.

9. The system of claim 1 , wherein the outputting the brain activity data, the obtaining the brain activity data, and the modifying the attribute of the electronic game are performed in substantially real time while the user concurrently plays the electronic game.

10. The system of claim 1 , wherein the electronic game requires physical interaction by the user with one or more user input devices for the user to play the electronic game.

11. The system of claim 1 , wherein:
the computing device is further configured to obtain game data representative of one or more characteristics of the electronic game; and
the modifying of the attribute of the electronic game is further based on the game data.

12. The system of claim 11 , wherein the one or more characteristics of the game represented by the game data comprise one or more of a current difficulty level of the electronic game, a current scene of the electronic game that the user is experiencing, a score achieved by the user while playing the electronic game, or an attribute of a user profile used by the user to play the electronic game.

13. The system of claim 11 , wherein the obtaining of the game data comprises receiving the game data from a gaming system that presents the electronic game to the user.

14. The system of claim 1 , wherein the computing device is further configured to present the electronic game to the user.

15. The system of claim 1 , wherein:
the computing device is further configured to:
determine, based on the brain activity data, a current mental state of the user, and
obtain data representative of a desired mental state of the user;

wherein the modifying the attribute of the electronic game comprises setting the attribute to a value configured to change the current mental state of the user to the desired mental state of the user.

16. The system of claim 1 , wherein the computing device is further configured to present, by way of a graphical user interface, content representative of the brain activity data.

17. The system of claim 16 , wherein the electronic game is presented to the user via the graphical user interface.

18. The system of claim 16 , wherein the graphical user interface is presented to one or more other users by way of a network.

19. The system of claim 1 , wherein:
the computing device is further configured to obtain sensor data associated with the user from a sensor not included in the brain interface system; and
the modifying of the attribute of the electronic game is further based on the sensor data.

20. The system of claim 19 , wherein the sensor data is representative of one or more of eye movement by the user, electrodermal activity of the user, pupillometry associated with the user, a heart rate of the user, heart rate variability of the user, or a pulse oximetry reading for the user.

21. The system of claim 1 , wherein the computing device is further configured to predict, based on the brain activity data, an action that the user will perform while playing the electronic game.
