Visualization Tool Feature List
The features are designed to serve performance gain from three aspects: visualization generation, visualization comparison and context-switch between visualizations.
| Objective | Feature |
|---|---|
| Allowing fast generation of temporal signal | Interactive spatial pattern visualization that allows a user to generate temporal signal by clicking on the position of a electrode |
| Allowing fast generation of spatial pattern | Real-time switch between different epochs with slider |
| Allowing fast generation of power/phase pattern | |
| Allowing fast comparison of two temporal signal | |
| Allowing fast comparison of two spatial pattern | |
| Allowing fast context-switch between different temporal signals |
