Design and Evaluation of Vibrotactile Stimulus to Support a KMI-based Neurofeedback

International audienceWe are developing a brain-computer interface integrating visual and vibrotactile feedback on the forearm and the hand in a gamified virtual environment to give situated and embodied information about the quality of stroke patients’ kinesthetic motor imagery (KMI) of a grasping movement. Multimodal sensory stimuli are used to provide a sense of embodiment [1]. Particularly, adding vibrotactile feedback is expected to improve the performance of a motor imagery task in neurotypical [2], [3], and stroke participants [4]
