a device that will enable it's user to enter his/her own dreams - a phenomenon known as lucid dreaming.


Computers for the Rest of You

a lucid dream is a dream in which the person is aware that he or
she is dreaming while the dream is in progress.

during lucid dreams, it is often possible to exert conscious control
over the dream characters and environment, as well as to perform
otherwise physically impossible feats. Lucid dreams are known to
be extremely real and vivid.

some possible benefits of lucid dreaming include:
personal exploration, greater access to creativity, self-hypnosis, and overcoming recurring nightmares.

to this end, this device senses the onset of the REM cycle while the user sleeps. upon detection of the cycle it introduces an external stimulus which subconsciously reminds the user that he/she is dreaming. this interaction, the subconscious reminder, enables dreamers to step into a new relationship with their dream - with the recognition that one is dreaming, one can take hold of the direction of that dream.

after pursuing temperature-based triggering of the device, i discovered that the variability of body temperature is too great during the night, and began to look for other methods to detect REM onset. after speaking to several doctors/researchers at Albert Einstein Medical Center, i decided to look at galvanic skin response as a legible mapping of sleep cycles. with only a vague idea that there might be some sort of connection between GSR and REM, i began gathering data on myself as i slept. this device is an outgrowth of that data mining.

anyone interested in dreaming or exploring further their own mind.

User Scenario
getting into bed, the user puts a ring-like sensor on one finger and turns on the device. it gathers data for the first hour, building a baseline figure. from that point on, whenever levels deviate below a certain point a small sound is played inside the user's pillow: a signal to remind the sleeping mind that it is dreaming. this triggers the start the process of lucid dreaming.

materials include galvanic skin response sensor, arduino, hacked mp3 player, and a pillow.

gathering data in your sleep is exhausting.
