BACKGROUND

- Top of Page


Through numerous interactions with computer systems in their day-to-day lives, users are exposed to a wide array of content, such communications (e.g., video, instant messaging, or interacting with a virtual agent) and various forms of digital media (e.g., internet sites, television shows, movies, augmented reality, and/or interactive computer games). Throughout these many interactions, affective computing systems can measure a user's affective response to the content and analyze the information. This analysis may provide insight that can be used to improve the current and/or future content presented to the user.

Since the sensors used to measure users are typically mobile and/or wireless (e.g., bracelets with GSR sensors, cameras, headsets with EEG sensors, or implants), they often rely on batteries for power. However, continuous measurements of a user can consume a lot of power, which drains the sensors' power source. Thus, enabling computer systems to continually receive user's measurements can be problematic when battery powered sensors are involved.

The need to supply sufficient power for operating the sensors and/or analyzing the data they produce is currently met by unsatisfactory means. For example, the size of the battery powering a sensor may be increased, but this is undesirable since it makes the mobile devices more cumbersome and less comfortable for the user. Another inconvenient possibility is to recharge power sources more often to meet the power demands. Yet another possibility is to measure users less or decrease the quality of the measurements, thus reducing the sensors' power demands. But this is also problematic, since it means that the computer systems may reduce the quality of service provided to the users.

Thus, there is a need to reduce the power consumption of sensors used to measure affective response.

BRIEF

SUMMARY

- Top of Page


Some aspects of this disclosure include systems, methods, and/or computer programs that may be used to reduce power consumed to measure affective response of a user to content presented via a display of a head-mounted system such as augmented reality or virtual reality system.

Some embodiments include a content Emotional Response Analyzer (content ERA), which analyzes at least some of the content a user is exposed to in order to evaluate whether it is beneficial to measure the user's affective response to the content. Based on its analysis, the content ERA outputs an indication indicative of whether a certain threshold, related to an emotional response to the analyzed content, is reached. The content ERA may evaluate various aspects of the emotional response to the content. For example, the content ERA may evaluate how much confidence there is in a prediction of the emotional response to the content, how discernible the emotional response is expected to be if measured, whether the emotional response is of a desired type, and/or how beneficial it is to the system to determine the user's emotional response to the content.

Some aspects of this disclosure involve a controller that receives an indication generated by the content ERA after analyzing the content. The controller may utilize the indication in order to select a mode of operation for a sensor used to measure the user's affective response to the content. The controller may base its selection of the mode of operation on whether the indication indicates that a threshold related to the emotional response to the content was reached or not. In a case in which the indication indicates that the threshold was not reached, the controller may select a first mode of operation in which the sensor consumes significantly less power. In a case in which the indication indicates that the threshold was reached, the controller may select a second mode of operation, in which the sensor consumes significantly more power compared to the consumption when it operates in the first mode of operation.

Some aspects of this disclosure involve a controller that receives an indication generated by an interactive computed game that generates segments of content and tags indicative of a mode of operation for a sensor used to measure affective response to the segments.
