Aggregated stress monitoring to guide user interaction

A method for alteration of media content based on stress monitoring, the method comprising:

• presenting a media item in two distinct streams, the first stream presented to a first user on a first content presentation device, and a second stream presented to a second user on a second content presentation device;
• using sensor generated data to estimate a stress level for the first user and the second user;
• determining whether the estimated stress level for the first user exceeds a first predetermined stress threshold and whether the estimated stress level for the second user exceeds a second predetermined stress threshold;
• and
• in accordance with a determination that the estimated stress level for the first user exceeds the first predetermined stress threshold and the estimated stress level for the second user does not exceed the second predetermined threshold:
• altering the first stream of the media item to modify a particular portion of the media item associated with the estimated stress level for the first user without altering the second stream of the media item, wherein the first stream is altered such that it remains in sync with the second stream once the particular portion of the media content item has been presented.

At least one non-transitory computer-readable storage medium storing instructions that, when executed by the one or more processors of a machine, cause the machine to:

• present a media content item in two distinct content streams, the first content stream presented to a first user on a first content presentation device, and a second content stream presented to a second user on a second content presentation device;
• use sensor generated data to obtain a first user response indicator for the first user and a second user response indicator for the second user;
• estimate a stress level for the first user based on the first user response indicator;
• estimate a stress level for the second user based on the second user response indicator;
• determine whether the estimated stress level for the first user exceeds a first predetermined stress threshold;
• determine whether the estimated stress level for the second user exceeds a second predetermined stress threshold;
• in accordance with a determination that the estimated stress level for the first user exceeds a first predetermined stress threshold and the estimated stress level for the second user does not exceed a second predetermined threshold:
• associate the estimated stress level for the first user with a particular portion of the media content item;
• and
• alter the first stream of the presented media content item to modify the particular portion of the media content item associated with the estimated stress level for the first user without altering the second stream of the presented media, wherein the first stream is altered such that it remains in sync with the second stream once the particular portion of the media content item has been presented.
