I now have an infrared LED shining down on me from a cupboard… and the recordings have been out of this world! Gone are the dark ages with just a few squiggly lines of questionable EEG signal quality.
The latest version of the Halovision plugin records an image-stream of any movements and Lucid Scribe automatically replays them when reviewing a session. This helped a lot with writing filters for the artefacts, like when the camera re-focuses.
The eye movements that triggered the audio track can be seen in the minute above. I was re-taming a hippo that I had saved as a baby in another life!
Here is the finalised release candidate of the Halograph EOG – a headband with a night-vision camera held in place by two bendable selfie-sticks:
It is more comfortable to sleep in than I had ever hoped. I can sleep on either side or on my back with complete freedom of movement with the 2 meter cable.

I have been working on a new plugin for Lucid Scribe, dubbed Halovision, that measures the amount of change between each frame from a webcam stream. The printout above was recorded while awake and blinking and shows the eye movement pattern that triggers the audio tracks. If you always wanted to try Lucid Scribe but haven’t had the hardware, now is your chance if your laptop has a webcam built in or your smartphone runs Android!
