Emotion judgment wearable device and method based on body surface extremely-low-frequency potential difference characteristics

Abstract

The invention discloses an emotion judgment wearable device and method based on body surface extremely-low frequency potential difference characteristics. The potential difference between two points on the skin of a human body is directly collected at an extremely low frequency below 1Hz, the time domain data of the potential difference is subjected to data analysis processing to obtain emotionalcharacteristics, and the emotional characteristics are input into an emotional judgment model to judge different emotions; and the wearable device comprises a differential amplification module, an active low-pass filtering module, a boosting module, an AD conversion module, a main control module, a wireless communication module, a lead falling detection module, a low electric quantity detection module and a working state display module. According to the present invention, accurate basic emotion recognition can be performed based on the body surface extremely-low frequency potential differencecharacteristics of the specific part of the human body, and the wearable device is small in structural design and convenient to wear.

Description

technical field [0001] The invention belongs to the wearable device and method in the field of physiological signal monitoring and emotion judgment, and specifically relates to an emotion judgment method based on the characteristics of extremely low-frequency potential difference on the body surface and the matching wearable device and method. Background technique [0002] Emotion recognition is an important part of the field of emotional computing, because in the process of human-computer interaction, people usually have certain emotions. If the computer can understand human emotions, it can provide better human-computer interaction. experience. At the same time, the development of this technology is also of great significance to the use of computers and other electronic devices by patients who cannot speak and have limited mobility to communicate with the outside world or transmit information to the outside world. [0003] At present, the research objects of emotion recog...

Problems solved by technology

Likewise, external factors such as lighting conditions, accessories such as glasses or hats, and surrounding audio noise may affect the accurate delivery of these signals

The external expressions of these emotions can be easily faked, which limits the application of these signals in computers
