1. A method, comprising:

rendering a view of a virtual environment through a virtual reality (VR) headset;

using a camera in the VR headset to detect a gaze direction and a gaze focus depth of a user that wears the VR headset;

using an EEG sensor in the VR headset to detect an electroencephalography (EEG) signal of the user that wears the VR headset;

using the gaze direction and gaze focus depth of the user to identify a virtual object in the virtual environment as being actively viewed by the user;

using the EEG signal to determine a concentration of the user upon the identified virtual object;

responsive to determining the concentration of the user upon the identified virtual object, then rendering a graphical indicator applied to the virtual object in the view of the virtual environments;

receiving controller input from a controller device held by the user, and, further responsive to determining the concentration of the user upon the identified virtual object, then applying said controller input to effect a movement of the identified virtual object in the virtual environment.

2. The method of claim 1 , wherein using the EEG signal to determine the concentration of the user includes applying a trained machine learning model to recognize the EEG signal, the trained machine learning model being trained using prior EEG signal data of the user.

3. The method of claim 1 , wherein the graphical indicator is configured to indicate selection of the identified virtual object.

4. The method of claim 1 , wherein the graphical indicator is configured to include a menu of options to be applied to the virtual object.

5. The method of claim 1 , further comprising:

receiving gesture input of the user, and applying said gesture input to effect a change in the virtual object.

6. The method of claim 1 , wherein the virtual environment is a virtual environment of a video game, and wherein the virtual object is a virtual object of the video game.

7. A non-transitory computer readable medium having program instructions embodied thereon that, when executed by at least one computing device, cause said at least one computing device to perform a method, said method comprising:

rendering a view of a virtual environment through a virtual reality (VR) headset;

using a camera in the VR headset to detect a gaze direction and a gaze focus depth of a user that wears the VR headset;

using an EEG sensor in the VR headset to detect an electroencephalography (EEG) signal of the user that wears the VR headset;

using the gaze direction and gaze focus depth of the user to identify a virtual object in the virtual environment as being actively viewed by the user;

using the EEG signal to determine a concentration of the user upon the identified virtual object;

responsive to determining the concentration of the user upon the identified virtual object, then rendering a graphical indicator applied to the virtual object in the view of the virtual environment;

receiving controller input from a controller device held by the user, and, further responsive to determining the concentration of the user upon the identified virtual object, then applying said controller input to effect a movement of the identified virtual object in the virtual environment.

8. The non-transitory computer readable medium of claim 7 , wherein using the EEG signal to determine the concentration of the user includes applying a trained machine learning model to recognize the EEG signal, the trained machine learning model being trained using prior EEG signal data of the user.

9. The non-transitory computer readable medium of claim 7 , wherein the graphical indicator is configured to indicate selection of the identified virtual object.

10. The non-transitory computer readable medium of claim 7 , wherein the graphical indicator is configured to include a menu of options to be applied to the virtual object.

11. The non-transitory computer readable medium of claim 7 , wherein said method further comprising:

receiving gesture input of the user, and applying said gesture input to effect a change in the virtual object.

12. The non-transitory computer readable medium of claim 7 , wherein the virtual environment is a virtual environment of a video game, and wherein the virtual object is a virtual object of the video game.
