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 | One-click generation of power/phase pattern corresponding to currently selected time and electrode | |
| Allowing fast comparison of two temporal signal | Option of displaying two temporal signal side-by-side | |
| Allowing fast comparison of two spatial pattern | Option of displaying two spatial pattern side-by-side | |
| Allowing fast context-switch between different visualizations | Layout design that minimizes estimated total eye movement distance (for a given session? can we make this adaptive?) |

Evaluation
- Task: In 5 minutes, try to find interesting pattern(s) in the given data that may lead to new hypothesis or scientific discovery.
- Measurement:
- 1. Number of time signals examined.
- 2. Number of topographies examined.
- 3. Questionnaire that measures cognitive load while completing the task.
- 4. Number of interesting patterns discovered.
- 5. Number of noisy data discovered.
