Explore sensor recordings from the Helios wrist device. Below, the full-dataset gesture
distribution is featured prominently, followed by interactive IMU time-series and TOF heatmaps. Use the
filters to drill down to sequences or see dataset-wide averages.

About this Web App
Overview
This dashboard visualizes processed recordings from the Helios wrist device. It provides a dataset summary,
interactive IMU time-series plots, and TOF heatmaps for either the dataset average or individual sequences.
How to use
Use "View Mode" to switch between dataset-average and per-sequence views.
Apply the gesture or subject filters to narrow the selection; the sequence selector updates accordingly.
In per-sequence mode, pick a sequence to render IMU time-series and the sequence-averaged TOF heatmap.
If TOF appears empty, check console logs for detected TOF column names or run the preprocessing step to
regenerate processed/ files.
Future directions
Persist user filter selections in the URL for shareable views.
Support multiple TOF sensors and per-cell value tooltips with absolute units.
Add export (PNG/CSV) and automated quality checks for missing sensor channels.
Improve performance for large datasets (virtualized lists, web workers).
