2016-02-04 – I may be a dreamer

EOG REM Eye Movements

I now have a setup that is fit for a princess! And finally have my wife hooked… she can be seen sneaking in a dream amidst her beauty sleep in the minute above.

The algorithm has a better time picking up her eye movements because her eye-lashes are darker.

I will add an option to get the lab setup in Heisenberg Blue in her honor!

EOG REM Graph

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 lay 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.

2016-01-28 – Look ma, no Headbands!

Sleep and Consciousness Research Graph

I was able to record some eye movements with the camera on the night-table next to me! It didn’t trigger the audio tracks… I will need to tweak the algorithm to trigger on subtler movements as the camera isn’t so close to the eyes anymore.

The headband definitely 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 followers!

2016-01-22 – Wingless Drone

Sleep and Consciousness Research Graph

The outline of the NoIR camera hanging from the halograph headband can be seen in the shadow in the minute above. It also used to create artefacts in previous versions of the algorithm, but appears to be fairing a little better now. My alarm is currently set for 7 but I have been waking up from REM at around 6:30 consistently this week.

Sleep and Consciousness Research Graph

I caught another today… the pillow can be seen in the minute above and doesn’t affect the algorithm anymore.

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…

2016-01-20 – Let there be Sight!

Sleep and Consciousness Research Graph

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!

Test run with the new halovision headband. I thought the red LED on the camera would suffice and didn’t have the infrared light on, but the camera kept trying to refocus, creating waves of noise.

2015-03-12 – first zeo test

Sleep and Consciousness Research Graph
so my experience was very nice last night…. i have to take back everything I said about your music! it was just fine… running the other music in the back ground worked great, when yours came on I stayed asleep but I was aware I was listening to the music and thought it was not bad. I enjoyed it….. I don’t remember my dreams or anything but it was a good first step…. it was comfortable…. the electrodes seemed to have slipped down and I took off the headset when I was awake at the end of the music

I recorded another session with the OpenEEG… this time with a proper signal as evidenced by the OpenEEG RAW channel. The audio plug-out triggered from the OpenEEG channel at 0118:
Eye Movements at 0118

And then from the halograph FM channel at 0333:

Heartbeat Spike at 0333

Lost signal with a false positive at 0411:

Bad signal at 0411

That should be enough for me to add a signal quality channel and avoid false positives.

2015-01-07 – EEG Stairs

Caught a nice flight of stairs from the OpenEEG channel in the minute below.

EEG Stairs

The signal quality tapered off here and there after that, which can only be seen in the raw EEG data… will add a signal quality channel to keep track of it.
