Added new smartwatch vibration settings to the INSPEC:
Added a marker to the hypnogram in the INSPEC lucid dreaming device’s REM episode player that highlights when the clips with eye movements were captured.
Added face rotation to the INSPEC firmware in 1.3.9, so REM detection also works when your head lies sideways in the frame.
The Pixel Range used to set how many changed pixels in a row count as movement. It now counts changed pixels in connected groups in any direction, which detects more subtle eye movements in all directions. It also more sensitive now, so the Pixel Range needs be increased from 6 to 12 to filter out background noise.
A new eye bursts function now counts an eye movement only when another one occurred within the 2.5 seconds before it. This helps to keep the artifact filter from filtering out valid eye movements when too much of the body is in the frame and breathing patterns cause repetitive motion signals.
Added over-the-air firmware updates!
Upgraded the REM Episode Player in Lucid Scribe for the INSPEC. Here I am scrolling really fast through all the frames then moving back and forth between some frames…
This is the session where I recorded my sleep in parallel with the CGX Patch EEG and the sleep stage classification lined up surprisingly well with the INSPEC.
Added a new Capture Frames Without REM option that saves a frame from the INSPEC when no REM has been detected for a configurable interval between 15 and 90 minutes. This is to help new users debug the camera angle and positioning when no clips of REM episodes are captured on the first nights.
Added an interactive hypnogram view for LSD files imported from the INSPEC lucid dreaming device.
Extended EDF file import.
I ran the INSPEC session with the CGX Patch EEG recording through three sleep stage classifiers: two models from ezscore (ez6 and ez6moe), and Dreamento’s DreamentoScorer. All three classifiers are trained on the ZMax, so on the CGX they flipped between stages a little too often.
The REM marks fall at the same times the INSPEC detected REM across all three classifiers. Especially the long REM periods late in the night, around hours three, five, and seven, show up in every one of them. The results are better than I dreamed!
The full session along with the raw files (including EDF) is on LSDBase:

I recorded an INSPEC session while wearing a clinical-grade EEG device, a CGX Patch on loan from a sleep research lab after I gave presentation on “Contactless REM Detection in Natural Sleep” and the history of the INSPEC.
The INSPEC logged a 20-minute run of eye movements that line up where I can also see spikes in the EEG data. I still need to run the EEG data through a sleep stage classifier, but it looks like they align from what I can see.
