Fig. 1From: Motor priming in virtual reality can augment motor-imagery training efficacy in restorative brain-computer interaction: a within-subject analysisExperimental Setup overview. (a) Experiment timeline, starting with a 15Â min briefing and setup, followed by 8Â min of BCI calibration, 15Â min of rest, 8Â min of online task performance, and questionnaires. (b) BCI calibration and MI task blocks. Starting with baseline measurement, the user waits for a cue followed by a pause (repeated 40 times, 20 per class). (c) Stages for the Control condition with the standard arrows-and-bars feedback. (d) Stages for the VR training feedback, replacing the directional arrows with virtual hands performing a task in a 3D immersive environmentBack to article page
