Problems solved by technology

However, sometimes the model predictions are not accurate enough, for example, facial image data representing a sneer or wry smile may be misidentified as a happy emotional state
Furthermore, for the same class of emotional states, such as negative emotions, existing models cannot distinguish between the manifestations of different developmental stages, i.e., cannot identify subtle differences between different degrees of the same class of emotions

Embodiment Construction

[0015] The examples described below are preferred embodiments of the present invention. In these examples, the described parts of the embodiment each represent individual features of the invention which can be considered independently of one another, which also improve the invention independently of one another, and thus also differ individually or in combinations other than those shown. Combinations are considered to be part of the present invention. Furthermore, the described embodiments can also be supplemented by other features of the invention that have already been described.

[0016] In the figures, functionally identical elements are provided with the same reference signs.

[0017] Existing voice feedback products aimed at the user's emotional state are mainly based on the following technical solutions:

[0018] - Obtain existing emotion recognition models or build new emotion recognition models;

[0019] -Detect the user's raw data, such as facial image data or voi...

Abstract

The invention relates to a method for determining information related to a user state based on original data of a user, the original data comprises face image data and/or voice data of the user, and the method comprises the following steps: acquiring the original data; and determining information related to a user state based on the original data, extracting feature information from the original data, and determining the information related to the user state based on a mapping relationship between the feature information and the information related to the user state, the feature information comprises features corresponding to other data information except the original data of the user.

Description

technical field [0001] The present invention relates to a method and device for determining information related to a user's state based on the user's original data, the original data including the user's facial image data and / or voice data. Background technique [0002] Especially in the automotive field, it is usually necessary to recognize or determine the driver's emotional state, and output corresponding especially voice feedback for the driver's emotional state, so as to appease the driver's emotions. However, the existing voice feedback products aimed at the user's emotional state are inefficient and costly, and are not satisfactory. [0003] Furthermore, when recognizing or determining a driver's emotional state, existing facial expression recognition and analysis models usually recognize the emotional state based on human facial image data. However, sometimes the model's predictions are not accurate enough, for example, facial image data representing a sneer or wry ...
