Real-time analysis and report

The Affective Cloud provides two ways to return values: real-time analysis and statistical reports.

Real-time computing of the affective computing value allows your product to respond to the user's physical and affective state in real-time. It allows you to develop products that interact with the user in real-time, for example, by determining in real-time whether the user falls asleep to decide whether to turn off the sleep aid music or not.

Reports over a period of time can allow users to understand their physical state and affection changes over a period of time. For example, the pressure-reduction effect of meditation can be measured by analyzing the pressure level change before and after the meditation user.

Real-time computed affective computing values

The values available for analysis are as follows.

Computing TypeComputing ServiceOptional Computing ValuesData Description

The service will return the results in real-time. For details, please refer to the interface protocol for the relevant parameters and configuration.


After computing, you can also choose whether you want to return a report of the computing analysis results, which can be used to count all the values generated during the current session. The optional computing return results report is as follows.
