Michael of Lucid Code has refined his own REM detection system project known as Halovision which is great news for us interested in sleep and dream research.
The device measures subtle electrooculography (EOG) muscle changes by means of a small 5 megapixel camera over the eye which records your eyelid movements digitally frame by frame via your associated computer device.

Added an option to record the video feed along with the Lucid Scribe Data files under \User\Documents\lucidcode\Lucid Scribe\Days\.
Made the program files path dynamic.
[Michael] has been working on projects involving lucid dreaming for a long time. The recurring problem with most projects of this nature, though, is that they often rely on some sort of headgear or other wearable which can be cumbersome to actually sleep with. He seems to have made some headway on that problem by replacing some of the offending equipment with a small camera that can detect eye movements just as well as other methods.
The idea behind projects like this is that a piece of hardware detects when the user is in REM sleep, and activates some cue which alerts the sleeper to the fact that they’re dreaming (without waking them up). Then, the sleeper can take control of the dream. The new device uses a small camera that dangles in front of an eye, which is close enough to monitor the eye’s movement. It measures the amount of change between each frame, logs the movements throughout the night and plays audio tracks or triggers other hardware when eye movements are detected.
[Michael] is looking for volunteers to provide sleep logs and run tests, so if you’re interested then check out the project!

Made the IP address configurable for devices with dynamic IP addresses.
Added support for the halovision headband (Halograph EOG). The one we have all been waiting for. A headband with a NoIR camera that measures the amount of change between each frame from the video stream.
It should still work with ordinary webcams, so give it a spin now to see the magic in action:
Introducing release candidate one. Camera up and filming the real world:
Camera down…
… deep down, recording eye movements:
Non-invasive, light-weight and as comfortable as it gets.

Updated the camera drop-down list and tweaked the REM detection algorithm.
It turns out Tre was onto something and Lucid Scribe works with the MyndPlay BrainBand out of the box.
Thanks to Leandro for getting it connected! Now we just need to figure out how to connect the grounding electrode more comfortably… maybe break the clip and use duct tape to keep it connected to the earlobe for extended periods?
A new plugin that logs and graphs ping time.
