Communication is an essential part of everyday living. However, many people suffer from conditions anddeficits that render them unable to communicate directly to others. For these individuals, a trained professionalis often required to assist them continuously, which makes it impossible for them to live independently. It alsoplaces a heavy financial and psychological burden on their families. This project aims at developing a systemwith which these individuals can communicate with their loved ones using only their thoughts, through atechnology called brain-computer interface. Their intentions will be decoded from their brain waves orelectroencephalogram (EEG), allowing them to control external devices. The research team will focus on aspecific EEG modality called Steady State Visual Evoked Potential (SSVEP) in this project, and mechanismswill be developed to provide individualized optimal electrode positions for this SSVEP-based BCI system thatis commercially viable.

沟通是日常生活的重要组成部分。然而，许多人患有疾病和缺陷，使他们无法直接与他人沟通。对这些人来说，经常需要训练有素的专业人员不断地帮助他们，这使他们无法独立生活。这也给他们的家庭带来了沉重的经济和心理负担。该项目旨在开发一个系统，通过一种名为脑机接口的技术，这些人可以只用他们的思想与他们所爱的人交流。他们的意图将从他们的脑电波或脑电图（EEG）中解码，使他们能够控制外部设备。研究团队将专注于一个特定的EEG模态称为稳态视觉诱发电位（SSVEP）在这个项目中，和机制将被开发，以提供个性化的最佳电极位置，这个基于SSVEP的BCI系统是商业上可行的。
