要約(日本語): The decoding of motor imagery (MI) of a sit-stand motion has been applied in brain-computer interfaces and rehabilitation. It has been previously studied with a paradigm of action observation (AO), MI, and motor execution with a visual guideline. This study aims to improve the previous paradigm with a self-perspective stimulus using virtual reality head-mounted displays (VR-HMD), which has promising results in other MI tasks but is yet to be explored in this task. We experimented with comparing the new paradigm using an immersive VR-HMD stimulus against an on-screen video stimulus. Results from electroencephalography recordings of AO and MI periods show differences in the alpha and beta bands. The decoding of sit-stand intention also slightly improved in VR.
