Multimodal visual, auditory, thermal, and tactile feedback during brain-machine interface use by a spinal cord injury patient

Detalhes bibliográficos
Resumo:The aim of this study was to investigate the performance of a spinal cord injury (SCI) patient in a multimodal BMI setup. The participant was required to modulate neural activity (i.e., using lower limb motor imagery) to control an avatar in complex virtual reality scenarios, while receiving coherent visual, auditory, tactile, and thermal feedback. In the sessions presented here, the participant consistently presented performances above chance levels. In addition, the participant reported “feeling his feet cold” in scenarios involving water. This study demonstrates that a spinal cord injury patient can control a brain-machine interface combining virtual reality (visual and auditory), tactile, and thermal feedback; supporting the notion that the increased number of feedback modalities did not generate an overload of information and can be used in the context of rehabilitation.
