| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Functional near-infrared spectroscopy (fNIRS) has been considered the application to brain-computer interfaces (BCIs) in many studies because of its simplicity of use and portability. However, scalp-hemodynamics often contaminates fNIRS signals as an artifact, and causes the markedly-degradation of the signal-to-noise ratio for functional signals. Although some studies have reported reduction method for the artifacts, no study has investigated its effects on BCIs. In this study, we investigated the effects of applying scalp-hemodynamic reduction to classifications for four tasks: a ball grasping with right, left, or both hands, or resting. As the artifact reduction method, we applied a previous proposed method that combining short source-detector distance channels and a general linear model. As results, the classification accuracy was improved after applying the scalp-hemodynamic reduction, suggested that the artifact reduction may provide the more accurate fNIRS-BCI. | |
