2024年7月1日 · Electroencephalogram (EEG)-based brain-computer interfaces (BCI) have been considered a prevailing non-invasive method for collecting human biomedical signals by attaching electrodes to the scalp. However, it is difficult to detect and use these signals to control an online BCI robot in a real environment owing to environmental noise.

2018年8月5日 · As a novel contribution, the reviewed BCI control paradigms for wearable LL and assistive-robots are presented by a general control framework fitting in hierarchical layers. It reflects informatic interactions, between the user, the BCI operator, the shared controller, the robotic device and the environment.

2020年9月7日 · Our results offer an approach for reliable, stable BCI control by leveraging the stability of ECoG interfaces and neural plasticity. A paralyzed individual controls a neuroprosthetic without...

This basic structure of BCI consists of signal acquisition, pre-processing, feature extraction, classification, and control of the devices. The signal acquisition paves the way to connecting a brain and a computer and to gathering knowledge from signals.

2017年2月5日 · Brain Computer Interface (BCI) is defined as a combination of hardware and software that allows brain activities to control external devices or even computers. The research in this field has attracted academia and industry alike. The objective is to help severely disabled people to live their life as regular persons as much as possible.

The bottom half of the figure shows the BCI communication pathways where brain signals are directly used to control external devices, bypassing traditional muscle control mechanisms. Sensory feedback is still integrated through traditional sensory pathways, allowing users to interact effectively with the environment.

2024年12月17日 · Abstract: The Brain-Computer Interface (BCI) Based Wheelchair Control System is a cutting-edge assistive technology designed to empower individuals with severe motor disabilities. This project leverages advancements in neuroscience and engineering to develop a wheelchair control system that enables users to navigate their environment using ...

2019年5月1日 · In this paper, a shared control strategy, which combines BCI control with computer vision guidance, is utilized to realize the control of a dexterous robotic arm for reach and grasp activities in a 3D space. With the assistance of the vision guidance, the simple two-class MI-based BCI is sufficient.

2024年12月17日 · Brain-computer interfaces (BCI) are electronic systems—either implanted in the brain or worn on the head—that let people control computers, robots, or other devices using brain signals. In clinical trials, BCIs have helped people with severe disabilities communicate and use robotic limbs, though these BCIs are not yet on the market.

2025年3月6日 · Summary: A new brain-computer interface (BCI) has enabled a paralyzed man to control a robotic arm by simply imagining movements.Unlike previous BCIs, which lasted only a few days, this AI-enhanced device worked reliably for seven months. The AI model adapts to natural shifts in brain activity, maintaining accuracy over time.
