Journal ArticleDOI
Temporally Constrained Sparse Group Spatial Patterns for Motor Imagery BCI
TL;DR: A novel algorithm, namely temporally constrained sparse group spatial pattern (TSGSP), is proposed for the simultaneous optimization of filter bands and time window within CSP to further boost classification accuracy of MI EEG.
Journal ArticleDOI
Immersion of virtual reality for rehabilitation - Review
TL;DR: Performance measures including postural stability, navigation task performance, and joint mobility showed varying relations to immersion and different haptic devices such as gloves and controllers provided both strengths and weakness in areas such movement velocity, movement accuracy, and path efficiency.
Journal ArticleDOI
Movement imagery-related lateralization of event-related (de)synchronization (ERD/ERS): Motor-imagery duration effects
TL;DR: Movement imagery-related lateralization can play a key role in utilizing motor-imagery tasks as a control or communication strategy when designing an EEG-based brain-computer interface (BCI) for people with severe neuromuscular impairments.
Journal ArticleDOI
Event-related (De)synchronization (ERD/ERS) during motor imagery tasks: Implications for brain–computer interfaces
TL;DR: In this article, the authors examined the potential impacts of movement duration on event-related desynchronization/synchronization (ERD/ERS) during motor imagery tasks with varying movement duration.
Journal ArticleDOI
Web-Based Learning Environment: A Theory-Based Design Process for Development and Evaluation
TL;DR: This study addressed weaknesses while developing a user-centered, Web-based learning support environment for Global Positioning System (GPS) education and evaluated the design process model by assessing the overall quality of the [WD.sup.2]L environment.
