Reducing transmissions of measurements of affective response by identifying actions that imply emotional response
View Patent ↗A system, method, and computer product for reducing volume of transmissions of measurements of affective response are described herein. In one embodiment, an interaction analyzer receives a description of an interaction of a user with a media controller that controls presentation of content to the user. The interaction analyzer identifies from the description an action that causes a deviation from a progression of presentation of the content that would have occurred had the action not taken place. A transmitter sends a request to transmit measurements of affective response, taken by a sensor, during a window during which the user likely expressed an affective response related to the action. In some embodiments, the request is received by a transceiver coupled to the sensor with memory sufficient to store measurements of affective response of the user taken since the start of the window, which precedes the time the request is sent.
1. A system configured to reduce volume of transmissions of measurements of affective response, comprising:
an interaction analyzer configured to receive a description of an interaction of a user with a media controller that controls progression of presentation of content consumed by the user;
a measuring module comprising a sensor configured to take measurements of affective response of the user while the user consumes the content;
the interaction analyzer is further configured to analyze the description in order to identify an action, performed by the user, which causes a deviation from a typical progression of presentation of the content, and to forward an indication of the action to a window selector; whereby the typical progression is a progression that would have occurred had the action not taken place;
the window selector is configured to select, based on the indication, a window during which the user expressed an affective response related to the action; wherein the window starts before the action is taken and ends at most one second after the action is taken;
a transmitter configured to send a request to the measuring module to transmit measurements taken by the sensor during the window; and
the measuring module further comprises a transceiver configured to transmit the measurements taken by the sensor during the window.
2. The system of claim 1 , wherein the measuring module further comprises a memory with capacity sufficient to store measurements of the user taken between the start of the window and the time the request is received by the measuring module; whereby the transceiver is further configured to fulfill the request, while reducing unnecessary transmissions, by transmitting, after receiving the request, measurements of affective response stored in the memory to fulfill the request.
3. The system of claim 2 , wherein the measuring module is further configured not to transmit a certain measurement of affective response if a request for the certain measurement of affective response is not received by the measuring module within a predetermined duration.
4. The system of claim 1 , wherein the sensor is implanted in the user.
5. The system of claim 1 , further comprising a label generator configured to generate a label based on the action; wherein the label is indicative of an emotional response, felt by the user, which is related to the action.
6. The system of claim 5 , further comprising a module configured to train a measurement emotional response predictor (measurement ERP) utilizing the label and corresponding measurements of affective response received from the measuring module.
7. The system of claim 1 , further comprising a measurement emotional response predictor (measurement ERP) configured to predict emotional response of the user from data comprising measurements of affective response received from the measuring module.
8. The system of claim 1 , wherein the window selector sets the window based on analysis of the action.
9. The system of claim 1 , wherein the window selector sets the window based on characteristics of the content.
10. A method for reducing volume of transmissions of measurements of affective response, comprising:
receiving a description of an interaction of a user with a media controller that controls progression of presentation of content consumed by the user;
taking measurements of affective response of the user, with a sensor, while the user consumes the content;
identifying from the description an action, performed by the user, which causes a deviation from a typical progression of presentation of the content; whereby the typical progression is a progression that would have occurred had the action not taken place;
selecting, based on an indication of the action, a window during which the user expressed an affective response related to the action; wherein the window starts before the action is taken and ends at most one second after the action is taken;
sending a request to transmit measurements of affective response taken by the sensor during the window; and
transmitting the measurements taken during the window.
11. The method of claim 10 , wherein the transmitting of the measurements is performed after receiving the request.
12. The method of claim 11 , further comprising determining that no request for a certain measurement of affective response was received within a predetermined duration, and not transmitting the certain measurement of affective response.
13. The method of claim 10 , further comprising storing measurements of affective response of the user taken by the sensor between the start of the window and time the request is received by the sensor in a memory.
14. The method of claim 13 , wherein capacity of the memory is sufficient to store measurements of affective response of the user taken at least 100 milliseconds before the request is received.
15. The method of claim 10 , further comprising generating a label based on the action; wherein the label is indicative of an emotional response, felt by the user, which is related to the action; and further comprising training a measurement emotional response predictor (measurement ERP) utilizing the label and received measurements of affective response corresponding to the action.
16. The method of claim 10 , wherein selecting the window is based on analysis of the action.
17. The method of claim 10 , wherein the selecting of the window is based on characteristics of the content.
18. A non-transitory computer-readable medium for use in a computer to reduce volume of transmissions of measurements of affective response; the computer comprises a processor, and the non-transitory computer-readable medium comprising:
program code for receiving a description of an interaction of a user with a media controller that controls progression of presentation of content consumed by the user;
program code for facilitating taking of measurements of affective response of the user, with a sensor, while the user consumes the content;
program code for identifying from the description an action, performed by the user, which causes a deviation from a typical progression of presentation of the content; whereby the typical progression is a progression that would have occurred had the action not taken place;
program code for selecting, based on an indication of the action, a window during which the user expressed an affective response related to the action; wherein the window starts before the action is taken and ends at most one second after the action is taken;
program code for sending a request to transmit measurements of affective response taken by the sensor during the window; and
program code for facilitating transmission of measurements taken during the window.
19. The non-transitory computer-readable medium of claim 18 , further comprising program code for selecting the window based on analysis of the action.
20. The non-transitory computer-readable medium of claim 18 , further comprising program code for selecting the window based on characteristics of the content.
