Thread: Things To Do With Motion Detection #9: check your sleep pattern
looking new applications motion detection, took santa claus detection system (http://ubuntuforums.org/showthread.p...ighlight=santa) , turned camera on myself...and fell asleep!
more precise, trained camera on head , let run on night. in morning had bunch of video clips.
guess people have seen sleep pattern graphs show how alternate between deep , shallow sleep through course of night. "research" validate this?
armed libre calc , grade 2 c.s.e. in woodwork, set plotting number of video clips time (see plot 1).
well, looks promising. @ least goes , down. wait moment, number of video clips going influenced threshold set in motion. , video clip generated quizzical raise of left eyebrow should not have same currency full barrel roll!
second attempt @ number crunching (yes, i'm getting swing of now) value each video clip based upon file size (see plot 2).
looks more it. adding video clip file sizes , plotting 30 minute total value (in mb) seem have graph can hang hat on. there more tuning do, have admit leaving "gap" setting @ 60s default value.
started me wondering: (1) body movement relate depth of sleep? (2) how movement of nocturnal partner(s) influence movements? (3) sleeping on water bed invalidate results?
well, that's sorted, i've got give mates on @ cern hand sort out naughty neutrinos. science lark easier thought!
afaik, yes. when you're in rem lose muscle tone. you'd able move around when you're not in rem.posted stevedee
