Silent mouthing“open that now”
Composite example: blink, smile and silent mouthingThree separate, independently scaled examples; not a continuous recording. Blink and smile are measured optical excerpts at 2.85–3.60 seconds and 10.40–11.65 seconds. Silent mouthing shows the two mean-absolute feature profiles of the current learned “open that now” pattern across 64 template columns, not elapsed time or raw LED channels.

About Blueberryˣ

Blueberryˣ was started to help people better understand their state of mind and body. We are bringing to market a miniature biosensor (fNIRS - functional near-infrared spectroscopy).

The team (Daniel and JD) behind Blueberryˣ is small and nimble covering neuroscience, software, hardware and sensors.

Blueberryˣ was founded in the winter of 2019 by JD (email) with the mission to improve well-being through the use of bio-sensing and feedback.
