MicroCloud Hologram launches its holographic BCI data acquisition system
Globaspec News Desk | May 11, 2023MicroCloud Hologram Inc. provider of hologram digital twins technology, has announced the launch of its holographic brain-computer interface (BCI) data acquisition system.
The holographic BCI data acquisition system combines BCI with holographic technology, enabling the two to complement each other. Holographic technology can be used as an information feedback tool for BCI systems, providing more realistic and contextual feedback for a more immersive user experience. BCI can be used as an input device for the holographic system, providing more direct and faster input, according to its developers.

The system converts the EEG data/other bio-electric signals obtained from the front-end analogue amplifier into digital signals via an A/D converter and transfers them to a computer via an interface with the computer for subsequent processing. The system combines the data transmitted from the BCI to the computer with the holographic 3D image data generation technology and processes the corresponding data information to generate holographic 3D data.
The holographic BCI data acquisition system includes EEG amplification holographic data generation part, the digital control part and the intelligent algorithm part. EEG amplifier circuit is mainly used to complete the holographic data amplification of EEG to facilitate the subsequent holographic data processing of EEG acquisition system. As EEG is a very weak electrical signal with strong noise background, the EEG amplifying circuit is an important part of the whole data acquisition system, which impacts holographic data generation. The digital control portion is composed of digital signal processing (DSP), AD sampling, holographic digital filtering and other modules, and the intelligent algorithm portion is the EEG signal recognition and matching holographic data through the algorithm to complete the holographic data generation. The amplification circuit of the holographic brain-computer interface extracts the amplified EEG signal and sends it to AD for analogue-to-digital conversion. The AD sampling of the EEG signal is controlled by DSP, and then the digital EEG signal sampled by AD is sent to the holographic digital filtering by DSP. The filtered EEG signal is then recognized and matched by an intelligent algorithm according to the holographic data in the holographic data tag library. Finally, the EEG holographic data is displayed and saved by various complex algorithms and parallel communication.
Currently, the holographic BCI system is still in its initial stage, and its main application goal is to assist medical rehabilitation medicine, and expand and repair people's cognitive or motor sensory functions. BCI technology has also been used in aerospace, robotics, multimedia and other fields.
The holographic BCI system opens up a variety of new information output channels for the brain, expanding the holographic display of the brain's interaction with the outside world, contributing to a deeper understanding of the brain's information transmission and control patterns, and provides a transformative approach to the analysis of brain stimulation and neuronal interactions, which will significantly enrich the content of brain cognitive science and neuroinformatics.
