Placebo I found a device not long ago on the internet called an OCZ NIA its a headbad that u could quite easily sleep wearing and it can detect alpha/beta waves muscle movement and lateral eye movement they cost around £85. The plug into computer via usb and come with calibration software and software that allows u to map ur brains events into emulated keyboard keypresses eg u could have 1 key press for looking right and another for looking left. The OCZ NIA is origanlaly aimed at gamers but you could quite easily detect these keypresses in another custom made program and then send out messages like "you are dreaming" or something to some small in-ear earphones that u also wear while you are asleep or something. I beleve alpha and beta waves also change during different stages of sleep which may make detecting dreams more acurate with some experimentation. |
