A brain‐computer interface for operating an electric wheelchair (wheelchair BCI) has been studied to support independent living for physically disabled patients. The current wheelchair BCI systems are facing the problem that the wheelchair cannot be moved or rotated to an arbitrary place or direction in a single measurement. To solve this problem, we developed a BCI that uses audiovisual stimuli based on mixed‐reality (MR) and virtual sound sources. During the online analysis, six out of seven participants were able to move or rotate the wheelchair to the target location or direction at a rate higher than the chance level. Thus, our results indicate that audiovisual stimulation with MR and virtual sound sources may be useful for intuitive wheelchair operation. © 2024 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

利用混合现实和虚拟声源的脑机接口控制电动轮椅

人们已经研究了用于操作电动轮椅（轮椅 BCI）的脑机接口，以支持身体残疾患者的独立生活。目前的轮椅BCI系统面临着轮椅无法在单次测量中移动或旋转到任意位置或方向的问题。为了解决这个问题，我们开发了一种脑机接口，它使用基于混合现实 (MR) 和虚拟声源的视听刺激。在在线分析过程中，七名参与者中有六名能够以高于机会水平的速度将轮椅移动或旋转到目标位置或方向。因此，我们的结果表明，MR 和虚拟声源的视听刺激可能有助于直观的轮椅操作。 © 2024 日本电气工程师协会和 Wiley periodicals LLC。
