I now have a setup that is fit for a princess! And finally have my wife hooked up… she can be seen sneaking in a dream amidst her beauty sleep in the minute above.
The algorithm had a good time picking up her eye movements – the dark eye-lashes helped it along nicely.
I will add an option to get the lab setup in Heisenberg Blue in her honor!

The vREM channel faired pretty well with the new tweaks to the algorithm. I rolled into position at 05:24 and had an intense dream from 05:48 until 05:51. Then laid dead still for a minute and finally awoke from it and rolled out of it at 05:52. The algorithm differentiated the rolling motions from the eye movements pretty well.
The latest version of Lucid Scribe can now also export the image data so the EOG can be re-viewed remotely! This increases the file size significantly, so I only uploaded 5 am.

I was able to record eye movements with the camera on the bedside table next to me!
The headband still records more dreams as it trains the camera on your eyes as you move around throughout the night, but is a challenge to sleep with for the casual user. And this setup brings the cost down by 100 and hopefully clears the way for more research!

I have had a few inquires about using the setup without the headband and this shows that it could work if you can sleep close enough to the night-table or have the camera mounted above the bed somehow. I will try to record a session like that one night…

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.
The age of light is nigh; this is light-bending!

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!
