Abstract

Methods and apparatus for identifying potentially seizure-inducing virtual reality content are disclosed herein. An example apparatus includes a virtual reality presentation device to display virtual reality content for exposure to a user and a neurological data collector to access first neurological response data collected from the user during exposure to the virtual reality content. The example apparatus includes a predictor to generate a prediction on a likelihood that a portion of the virtual reality content will trigger a seizure based on a first vector characterizing the portion and the first neurological response data. The example apparatus includes a content modifier to modify the portion of the virtual reality content into modified virtual reality content in response to the prediction. The content modifier is to transmit the modified virtual reality content to the virtual reality presentation device.

First claim

What is claimed is:

1. An apparatus for analyzing virtual reality content, the apparatus comprising:
a virtual reality presentation device to display the virtual reality content for exposure to a user;
a neurological data collector to access first neurological response data collected from the user during exposure to the virtual reality content;
a predictor to generate a prediction on a likelihood that a portion of the virtual reality content will trigger a seizure based on a first vector characterizing the portion and the first neurological response data; and
a content modifier to modify the portion of the virtual reality content into modified virtual reality content in response to the prediction, the content modifier to transmit the modified virtual reality content to the virtual reality presentation device.

2. The apparatus of claim 1 , further including a video analyzer to generate the first vector based on a visual parameter of the portion of the virtual reality content.

3. The apparatus of claim 1 , wherein the predictor is to further generate the prediction based on a second vector and second neurological response data, the second vector and the second neurological response data associated with a second portion of the virtual reality content presented prior to the presentation of the portion of the virtual reality content.

4. The apparatus of claim 1 , wherein the portion of the virtual reality content includes a plurality of video frames and the content modifier is to modify the portion of the virtual reality content by adjusting at least one of a saturation value, a hue value, or a luminance of at least one of the video frames.

5. The apparatus of claim 1 , wherein the neurological data collector is to access second neurological response data collected from the user, the second neurological response data collected during presentation of the modified virtual reality content, and further including a feedback analyzer, the feedback analyzer to determine a modification for the modified virtual reality content based on the second neurological response data.

6. The apparatus of claim 5 , wherein the content modifier is to stop a transmission of the virtual reality content based on the second neurological response data.

7. The apparatus of claim 1 , further including an alert generator to generate an alert based on the prediction.

8. A method for analyzing virtual reality content, the method comprising:
accessing, by executing an instruction with at least one processor, first neurological data collected from a user during exposure of the user to the virtual reality content;
generating, by executing an instruction with the at least one processor, a prediction on a likelihood that a portion of the virtual reality content will trigger a seizure based on a first vector characterizing the portion of the virtual reality content and first neurological response data;
modifying, by executing an instruction with the at least one processor, the portion of the virtual reality content to generate modified virtual reality content in response to the prediction; and
transmitting, by executing an instruction with the at least one processor, the modified virtual reality content to a virtual reality presentation device.

9. The method of claim 8 , further including generating the first vector based on a visual parameter or an audio parameter of the portion of the virtual reality content.

10. The method of claim 8 , wherein the generating of the prediction is further based on a second vector and second neurological response data, the second vector and the second neurological response data associated with a second portion of the virtual reality content presented prior to the presentation of the portion of the virtual reality content.

11. The method of claim 8 , wherein the portion of the virtual reality content includes a plurality of video frames and the modifying of the portion of the virtual reality content includes adjusting at least one of a saturation value, a hue value, or a luminance of at least one of the video frames.

12. The method of claim 8 , further including:
accessing second neurological response data collected during presentation of the modified virtual reality content; and
modifying the modified virtual reality content based on the second neurological data.

13. The method of claim 12 , wherein the modifying of the modified virtual reality content includes stopping a transmission of the virtual reality content.

14. The method of claim 8 , further including generating an alert based on the prediction.

15. A non-transitory computer readable storage medium comprising instructions that, when executed, cause a machine to at least:
access first neurological data collected from a user during exposure of the user to virtual reality content;
generate a prediction on a likelihood that the virtual reality content will trigger a seizure based on a first vector characterizing the virtual reality content and the first neurological response data;
modify at least a portion of the virtual reality content to generate modified virtual reality content in response to the prediction; and
transmit the modified virtual reality content to a virtual reality presentation device.

16. The non-transitory computer readable storage medium of claim 15 , wherein the instructions, when executed, further cause the machine to generate the first vector based on a visual parameter or an audio parameter of the virtual reality content.

17. The non-transitory computer readable storage medium of claim 15 , wherein the instructions, when executed, further cause the machine to generate the prediction based on a second vector and second neurological response data, the second vector and the second neurological response data associated with earlier presented virtual reality content.

18. The non-transitory computer readable storage medium of claim 15 , wherein the virtual reality content includes a plurality of video frames, and the instructions, when executed, further cause the machine to modify the at least the portion of the virtual reality content by adjusting at least one of a saturation value, a hue value, or a luminance of at least one of the frames.

19. The non-transitory computer readable storage medium of claim 18 , wherein the instructions, when executed, further cause the machine to access second neurological response data collected during presentation of the modified virtual reality content and to modify the modified virtual reality content based on the second neurological data.

20. The non-transitory computer readable storage medium of claim 15 , wherein the instructions, when executed, further cause the machine to generate an alert based on the prediction.
