To investigate this, we developed and validated a system using immersive head-mounted displays (HMD) to assess football players’ abilities, thus potentially enhancing positional memory. We assessed experienced and inexperienced players in a virtual football setting with randomly placed players. We measured the time and perspective shifts required to reconstruct player positions from a bird’s-eye view. Further, both groups observed players in a virtual environment and then reconstructed their positions for accuracy. Compared to inexperienced players, experienced players showed higher precision in reconstructing the spatial arrangement of player objects, suggesting the feasibility of evaluating the transition from first-person to bird’s-eye view. The system enables us to assess ball control, memory of teammate and opponent positions, and recall of key player positions for future plays. This demonstrated the value of the immersive HMD system, which can quantitatively manipulate VR variables, in comprehensively understanding cognitive relationships. Expanding this system for evaluating player attributes and training football players holds great promise. DOI： 10.1080/18824889.2024.2366552 Scopus
Nuruki A., Takenaka A., Miyazono T., Nuruki H. . Augmenting Sensory Attenuation Via Feedback Control: Innovations in Neuropsychiatric Rehabilitation . 2024 SICE Festival with Annual Co2024 · 記述言語： 日本語 出版者・発行元： 2024 SICE Festival with Annual Conference, SICE FES 2024 Sensory attenuation, which is the brain's mechanism to differentiate self-generated actions from external ones, identifies self from non-self, and is impaired in disorders such as schizophrenia and Parkinson's disease. This impairment can result in hallucinations and delusions owing to the misattribution of self-produced stimuli as external stimuli. Considering the limitations of traditional diagnostics in detecting these perceptual changes, sensory attenuation is a promising assessment and intervention tool. This study examined the effect of auditory and visual feedback on sensory attenuation in healthy adults, proposing its enhancement as a rehabilitative strategy for psychiatric disorders. Through experiments, we assessed the impact of feedback on sensory attenuation and its relationship with psychological state. Auditory feedback was found to significantly influence sensory attenuation. However, combined feedback and long-term effects were not observed. The link between sensory attenuation and psychological indicators suggests the potential for targeted modulation in individuals with schizophrenia-like mental states. This study highlights the potential of feedback-based modulation of sensory attenuation in the development of rehabilitation techniques for neuropsychiatric conditions, and sets the stage for further research on its long-term application in clinical settings.
