2019-02-20 – Face Recon

0400

The INSPEC can now look for faces and only looks for eye movements within the area of a face, nuking a whole host of false positives from sleep artifacts like breathing. Sleep talking still gets past it – too shy to post a clip of that, but I figure if you are sleep talking there is a good chance you are dreaming and the inhibition of motor neurons from REM atonia just isn’t working around the mouth muscles.

The video above shows some eye movements at 4 am with the algorithm looking for a face multiple times a second. In order for the facial algorithm to work, I have to bend the “neck” of the device so it can see my face in portrait mode. The flexible tripod works perfectly for that.
I sometimes feel guilty about how hard the INSPEC has to work all night, but I am making it in hope of spreading lucidity, so at least it is for a worthy cause.

2019-01-25 – Human Perspective

I added some more configuration options to the settings and the algorithm still worked! It picked up the eye movements when I was lying on my back with my head tilted slightly.

The device doesn’t have a clock when it is unplugged, so the date can now be configured if you want kind-of accurate timestamps on the files. It hovers on an insect-like tripod so the camera angle can now be controlled much better.

This recording better illustrates what the bitmaps look like that are saved to the SD card when eye-movement patterns are detected. Larger movements, especially in the mornings when there is some light from the rest of the spectrum still produce the deep-dream like images.

 

2019-01-16 – Deep Dream

I want to believe I almost have the perfect version of the halovision device. Down to the size of a matchbox; no screen – only a night-vision camera, infrared LEDs and a processor powerful enough to run the latest machine vision algorithms at a decent rate. It records short GIFs along with BMP stills to a SD card and triggers bright LEDs when eye-movement patterns are detected after a long enough still phase. I don’t think I can make the GIFs as high-res as these “research” grade ones, I’m afraid, but good enough to see what it was detecting to help get into position. Woo hoo!

2016-11-30 – Third Eye

I recorded an interesting phenomenon throughout the second hour of last night’s session… I want to believe that I caught evidence of the fabled third eye because the camera doesn’t have an infrared filter and frequencies and all that, but – as a man of science, have to settle on finding the infrared spotlight reflecting off my forehead cool enough.

The audio track woke me up after just a few seconds. My eyes can be seen opening in the real world after looking around in the dreamworld in the minute featured above. I have since started a shortlist of tracks that play only a few melodies for a couple of seconds that we have been having more luck with: Shortlist.

I rolled into position at 0320 and was dreaming for the better part of the hour. The audio triggered at 0333, again at 0334 and I dreamt through the tracks without waking. I recalled 3 dreams.

Rapid Eye Movements During Dream

The REM-detection algorithm is now ready to be burnt to the standalone version of the sleep lab and can be seen climbing the planes in the minute above.

I could hear Bob’s voice, but had the most annoying itch on my chin that caused major instabilities in NPR. I tried to hang on for dear life, but the itch was so overpowering that I could not hold still for long. When the eye movements subsided a few minutes later, the twitch grew so strong that it almost triggered the next track.

EOG REM Eye Movements

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!

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 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.

Sleep and Consciousness Research Graph

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!
