EEG MI-BCI Multidirectional Mouse Cursor Dataset (Open-BCI Ultra cortex mark-IV)

This dataset comprises EEG recordings collected for a multidirectional motor imagery-based brain-computer interface (MI-BCI) aimed at controlling a mouse cursor. The data were acquired using the Open-BCI Ultra cortex mark-IV 8 channel wireless EEG headset, which captured brain signals associated with voluntary motor imagery activities. Participants performed trials involving six distinct tasks: (1) imagining right-hand movement, (2) imagining right-leg movement, (3) imagining left-hand movement, (4) imagining left-leg movement, (5) eye blinking, and (6) resting (break) periods. All recordings were conducted at the Biomedical Instrumentation and Signal Processing Laboratory (BISPL), Independent University, Bangladesh.本数据集包含为开发用于控制鼠标光标的多方向运动想象型脑机接口（MI-BCI）所采集的脑电图（EEG）记录。数据采集采用Open-BCI Ultra cortex mark-IV型8通道无线脑电图头戴设备，该设备可捕获与自主运动想象活动相关的脑信号。受试者完成了包含6项不同任务的试验：(1) 想象右手运动；(2) 想象右腿运动；(3) 想象左手运动；(4) 想象左腿运动；(5) 眨眼；(6) 静息（休息）时段。所有记录工作均在孟加拉国独立大学的生物医学仪器与信号处理实验室（BISPL）开展。
