Figure 1From: Speaking and cognitive distractions during EEG-based brain control of a virtual neuroprosthesis-armActions used to control the 2D velocity of the virtual neuroprosthesis on the screen. Participants commanded the continuous 2D velocity of the fingertip of the virtual arm as it moved along a table top in a center-out-and-hold task. EEG changes associated with varying degrees of physically moving/resting the feet were used to command the virtual fingertip proximally-distally, while the degree of physically moving/resting the right hand was used to command the virtual fingertip right-left.Back to article page
