虽然脑机接口（BCI）可以为被锁定的人提供通信，但它们的信息传输率非常低。此外，使用 BCI 需要集中注意力，连续使用可能会很累。本文描述的脑控轮椅 (BCW) 旨在以安全有效的方式为 BCI 用户提供移动性，尽管存在这些限制。使用基于 P300 的缓慢但可靠的 BCI，用户可以在预定义位置列表中选择目的地。当轮椅在虚拟引导路径上移动时，确保平稳、安全和可预测的轨迹，用户可以通过使用更快的 BCI 来停止轮椅。对非残疾受试者的实验证明了该策略的有效性。当轮椅运动时，大脑控制不受影响，并且与文献中提出的其他控制策略相比，BCW 使用户能够在更短的时间内移动到各个位置，并且控制工作量显着减少。
While brain-computer interfaces (BCIs) can provide communication to people who are locked-in, they suffer from a very low information transfer rate. Further, using a BCI requires a concentration effort and using it continuously can be tiring. The brain controlled wheelchair (BCW) described in this paper aims at providing mobility to BCI users despite these limitations, in a safe and efficient way. Using a slow but reliable P300 based BCI, the user selects a destination amongst a list of predefined locations. While the wheelchair moves on virtual guiding paths ensuring smooth, safe, and predictable trajectories, the user can stop the wheelchair by using a faster BCI. Experiments with nondisabled subjects demonstrated the efficiency of this strategy. Brain control was not affected when the wheelchair was in motion, and the BCW enabled the users to move to various locations in less time and with significantly less control effort than other control strategies proposed in the literature.
