Thread: First post. Any freeware programs that will program laptop screen to provide time settable strobe?

Hi frascati. I'm developing a completely free Android App for lucid dreaming. It is a swiss army knife of lucid dreaming tools with an extremely customizeable timer. Right now it allows to plays sound and vibrate reminders while in suspected REM. In the next update, I plan to add the feature that you are describing - a light cue during suspected REM. The advantage of smart phones is that they are dead quiet. No fan noise, no cd drive spin ups, no hard drive clicks! It just sits there and then BAM - delivers a reminder. This update should happen within 10 days, as it's pretty easy to implement.

The phone's screen brightness can be adjusted to 100% over 10 seconds or so, then a series of light cues or images may be flashed. If the user is sleeping facing the phone, the light will most definitely be seen, as it is really bright. The exact timing will be set up by the user, I'll probably let you specify timing up to a millisecond. The app currently vibrates text in morse code, so the same pattern can be applied to light - enter some text to flash when the reminder is needed.



Here's how the app can be used to estimate sleep cycles and see when the reminders would've been played. This is an actigraphy history of several days of data with exact times of dream awakenings recorded. REM should happen before that. Orange triangles are dream awkening, we obviously want to deliver reminder a few minutes before that. The red line is when the app looks for dreams. The Xs above graph is when the app would've played the reminder on those nights. The Xs adjust their timing based on previous events during the same night. So lets say your REM just ended and you recorded a dream. If you let the app know, it will adjust the next event to occur sooner. If you would like to see any particular implementation of this feature, please tell me, and I may be able to make it happen.
