Adjusting display settings of a head-mounted display

1. An apparatus, comprising:

a processor;

a memory that stores code executable by the processor to:

receive sensor data from one or more sensors operably connected to a head mounted display (“HMD”) unit while a user wears the HMD unit;

determine a user's cognition level based on the sensor data, the cognition level indicated by the sensor data relative to a threshold, the threshold comprising a value that is associated with a predefined cognition level;

adjust one or more settings of a display of the HMD unit that has an effect on the user's cognition level based on the determined cognition level for the user;

monitor, over time, the user's cognition level based on new sensor data from the one or more sensors while the user wears the HMD unit;

further adjust the one or more display settings of the HMD unit based on the user's cognition level; and

notify the user that the one or more sensors are not positioned in a correct location on the user's head in response to not receiving sensor data from one or more of the sensors.

2. The apparatus of claim 1 , wherein the sensor data is sensed from one or more locations on the user's head, the one or more sensors coupled to a headband that is connected to the HMD unit.

3. The apparatus of claim 2 , wherein the sensor data comprises electroencephalography (“EEG”) data sensed from the one or more locations on the user's head.

4. The apparatus of claim 3 , wherein the EEG data comprises a measurement of a signal strength that the one or more sensors sense within the beta-wave range, the user's cognition level determined according to the measured signal strength.

5. The apparatus of claim 2 , wherein the one or more sensors comprise one or more electrode probes and the one or more locations on the user's head where the sensors are located is selected from the group consisting of FP1, FP2, TP9, and TP10 locations.

6. The apparatus of claim 1 , wherein the code is further executable by the processor to generate a baseline of sensor data for a period of time after the HMD unit is activated prior to determining the user's cognition level and adjusting the one or more display settings of the HMD unit.

7. The apparatus of claim 1 , wherein the code is further executable by the processor to acquire biometric data for the user, the biometric data further used to determine the user's cognition level.

8. The apparatus of claim 7 , wherein the biometric data is selected from the group consisting of a skin conductivity for the user, a heart rate for the user, a blood pressure for the user, and an oxygen level for the user.

9. The apparatus of claim 1 , wherein the code is executable by the processor to present one or more of an augmented reality (“AR”) environment and a virtual reality (“VR”) environment on a display of the HMD unit.

10. The apparatus of claim 9 , wherein adjusting one or more settings of the HMD unit comprises changing one or more settings of the VR and AR environment, the one or more settings selected from the group consisting of a brightness setting of elements presented on the display, a contrast setting of the display between elements presented on the display and an actual background, a color of elements presented on the display, and a size of elements presented on the display.

11. A system, comprising:

a head-mounted display (“HMD”) unit comprising a processor and a memory that stores code executable by the processor;

a headband coupled to the HMD unit; and

one or more sensors coupled to the headband and operably connected to the HMD unit,

wherein the code is executable by the processor to:

receive sensor data from the one or more sensors while a user wears the HMD unit;

determine a user's cognition level based on the sensor data, the cognition level indicated by the sensor data relative to a threshold, the threshold comprising a value that is associated with a predefined cognition level;

adjust one or more settings of a display of the HMD unit that has an effect on the user's cognition level based on the determined cognition level for the user;

monitor, over time, the user's cognition level based on new sensor data from the one or more sensors while the user wears the HMD unit;

further adjust the one or more display settings of the HMD unit based on the user's cognition level; and

notify the user that the one or more sensors are not positioned in a correct location on the user's head in response to not receiving sensor data from one or more of the sensors.

12. The system of claim 11 , wherein the one or more sensors comprise one or more electrode probes positioned at one or more locations on the user's head, the one or more locations selected from the group consisting of TP9, FP1, FP2 and TP10 locations.

13. The system of claim 12 , wherein the sensor data comprises electroencephalography (“EEG”) data sensed from the one or more electrode probes located on the user's head.

14. The system of claim 11 , wherein the code is executable by the processor to present one or more of an augmented reality (“AR”) environment and a virtual reality (“VR”) environment on a display of the HMD unit, the one or more settings of the VR and AR environment that are adjusted are selected from the group consisting of a brightness setting of elements presented on the display, a contrast setting of the display between elements presented on the display and an actual background, a color of elements presented on the display, and a size of elements presented on the display.

15. A method, comprising:

receiving, by a processor, sensor data from one or more sensors operably connected to a head mounted display (“HMD”) unit while a user wears the HMD unit;

determining a user's cognition level based on the sensor data, the cognition level indicated by the sensor data relative to a threshold, the threshold comprising a value that is associated with a predefined cognition level;

adjusting one or more settings of a display of the HMD unit that has an effect on the user's cognition level based on the determined cognition level for the user;

monitoring, over time, the user's cognition level based on new sensor data from the one or more sensors while the user wears the HMD unit;

further adjusting the one or more display settings of the HMD unit based on the user's cognition level; and

notifying the user that the one or more sensors are not positioned in a correct location on the user's head in response to not receiving sensor data from one or more of the sensors.

16. The method of claim 15 , further comprising generating a baseline of sensor data for a period of time after the HMD unit is activated prior to determining the user's cognition level and adjusting the one or more display settings of the HMD unit.
