Emotive EPOC XWireless portable EEG device EEG acquisition system

14 channel wireless EEG headset

Capture research grade EEG data at any time, using EPOC X: EMOTIV for the industryWireless EEG headset device.

Product Introduction

The Emotiv Epoc X wireless portable EEG system is a new human-machine interface control system developed by a neurotechnology company in San Francisco, California, USA - the Emotiv Epoc X headset. This device utilizes a device similar to an electroencephalogram that can measure brain electrical activity to detect and process brain wave patterns in real time. By using non-invasive sensors, Emotion can measure many different thoughts and emotions. Compared to previous technologies that could only detect basic and common mental states such as "concentration," Emotion can also distinguish specific thoughts such as "push" and "lift," as well as emotions such as "excitement" or "calmness. After wearing it, users can control the computer in front of them with just a heartbeat, and control the actions of video game characters through willpower and emotions.

Working Principle:

Emotiv EPOC X is the result of Emotiv Systems' five-year effort to develop a human brain/computer interface, primarily utilizing a non-invasive electroencephalography (EEG) technology that senses and learns the patterns of electrical signals from each user's brain neurons, reads the meaning of specific actions produced by the user's brain, and uses it toThe software analyzes and interprets the information, which is then converted into information that can be understood by computers or game functions. It interprets the thoughts, feelings, and emotions, and wirelessly transmits them to the computer to replicate the same actions on the screen. This not only allows virtual characters in the game to mimic the player's facial expressions, but also enables players to use their thoughts to move virtual characters around specified objects in the game.

Wear design:

The important part of the Emotiv EPOC X helmet is sixteen sensors, which closely adhere to the scalp to sense nerve signals and transmit the signals to the computer. Therefore, the wearing of Emotiv EPOC X requires a lot of knowledge and requires careful adjustment of position to achieve optimal resultsThe effect, and the amplitude of head shaking should not be too large during use. In order to help Emotiv EPOC X adapt to each user's unique neural signal transmission mode as soon as possible, the company has designed a computer game that allows users to enhance their cooperation and interaction with Emotiv EPOC X during the game. There is also a set of "Emokey" software that can be combined with existing applications or games on the user's computer to expand the application scope of Emotiv EPOC X.
