But as [Rob] showed on his blog, monitoring the lucid experience once it happens doesn’t have to be costly. Instead, household items can be fashioned together to make a mask that senses REM sleep cycles. We were tipped off to the project by [Michael Paul Coder] who developed an algorithm to communicate inside a dream.

[Rob] cut up plastic milk cartons for this ‘DreamJacker’ project and attached a webcam to produce a simple way to detect eye movements. A standard game adapter with a triangular array of white LED’s was added to the plastic cover in order to provide the necessary illumination needed for the camera. After testing it out, he switched to red light to balance sensitivity issues. Another iteration later and [Rob] attempted to create hypnagogic imagery during the drowsiness state that occurs right before falling…

Optical mouse hack

I recently came across Michael Paul Coder’s latest FIELD update on Lucidcode which was of great interest to me.

Basically this program is an upgraded version of his mouse control reader program for the LucidScribe platform.

The program, via the algorithm, could now detect the delicate movement picked up by the small camera sensor in the mouse where it would play a short soundtrack after several ‘movements’ over a short period of time.

It would be hoped that the mouse optics could be used as a form of REM eyelid movement or detection method, which might prove useful as a help in regard to lucid dreaming.

It should be noted, hardware wise, that using an optical mouse in this way is not a new idea where the LED is directly replaced with an IR counterpart.

I personally have come across some interesting articles on the Internet and forums…

Added a new channel: Mouse TCMP, which interprets Morse Code patterns from mouse movements and forwards them to the keyboard input. A small movement, above 32 is a dot, and anything above 100 is a dash. It is disabled by default so it needs to be enabled under plugins. It will type into any application that has focus and accepts keyboard input.

Mouse FIELD 1.1.0

Added a channel to detect eye movements from the infrared LED sensors operated out of mice. It is disabled by default because it is very sensitive, so it needs to be enabled under plugins.

Reverted the change from version 1.3.7 so that the minute view zooms in when the peaks are very subtle. Will make it configurable in the next version.

Lucid Scribe 1.3.8

Made the audio tracks trigger when the Zeo plugin enters stage 2 (REM).

Zeo 0.9.6

Merged Jef’s tweaks and added configuration options to trigger tACS devices connected via an Arduino board. The first drop down list determines the COM port the board is connected, the second drop down list sets the delay, in minutes. The first text box is the message it will send when eye movements are detected, and the second text box holds the message it will send after the delay has passed.

Zeo 0.9.5

Fixed the stage data.

Lucid Scribe 1.3.7

Scaled the axis on the minute view to 1000.

Added the NewLine value to the end of the messages to the Arduino board.
