And that complicated algorithms? If there are laws (and they are), then detect reaching the REM is not a problem, though not with the first ipulse, and with a slight delay.
Changes in the frequency of the pulse is so small that it is usually considered to be the pulse invariant depending on the sleep phase. Therefore write all these data, who has the desire, but to write a normal and make a real product for sale - it is quite another situation turns out. Although, I totally agree with You, there is nothing particularly complicated there. Here other questions arise. Why it is necessary to reduce the potential accuracy of determining the phase of the REM if there are many times more robust analysis method for eye movements? If You want to get rid of the mask, then how to issue basic, much-loved and recognized by all, lighting tips? How not to get lost in the wires when we start to give audio cues if headphones have to connect to the mask, and the bracelet on her arm, for example? Of course, you can solve all these problems wireless connections with additional modules, but is the game worth the candle?Волутар wrote:And that complicated algorithms?

well, if not a problem - we can spread a number of records made in the course of a month (even raw wav files, though with rozpoznany heart rate).Волутар wrote:And that complicated algorithms?

pulse changes between sleep stages were significant.Александр (разработчик) wrote: Changes in the frequency of the pulse is so small that it is usually considered to be the pulse invariant depending on the sleep phase.

personally, I'm doing a hobby project for myself. just for fun.So write down this data, anyone with the desire, but to write a normal and make a real product for sale - it is quite another situation turns out.
So I do not argue what can be done. It is not clear - whyТипаГость wrote:normal analysis can be done (eyes on the chart, and in the network there are plenty of pieces where painted such things) - I just have not enough experience in this field
Did not understand, something to think about, and what You propose to do? All that You have written, has long been implemented in the PRO version.Тапка ( под гостем))) wrote:Audio cues of the type you're in a dream ,try to fly and stuff,plus include binaural rhythm which supports consciousness in sleep ,vibrapods with a pre-generated at the reflex .
Me personally the money from the sale and development is not needed - I need something more......
Think about the people You crowds will float.
And why is it that You brought in sort of a strange conclusion? Spring came, and I just wanted to believe it? People buy DreamStalker, great use them, sometimes write here about their results. However, there are those citizens who don't even powers in the hands of this device, start anything and everything to throw mud. They name of the product, don't like, but the sound is not the same as in the concert hall, just like You - did not work to come up with that is not exactly like. On sleep phases, the device DreamStalker works very clearly, without mistakes, and that applies to all additional ideas, about which You wrote, as I already said above, they are all implemented in the new device DreamStalker PRO, which is issued for six months.Тапка ( под гостем))) wrote:Grimstalker as Novadreamer and other light-music does not give after so much time NO effect - the developers admit it.
If You are having any problems, you just need to understand the reason, because most users this is no problem. Sometimes complain that standard flash in the dream, but that the device did not work on the REM, this does not happen. Complained somehow, I remember one of the users, so then he wrote that as sort of undercut the foam with the mask form your face, and everything was fine. Sometimes on a mask onto the forehead or down the nose - like so they feel more comfortable and the sensor, of course, moves with the eye, and the device sees no movement of the pupil. Wear is fine - no problem. Uncomfortable to sleep with the mask on - that's a separate issueТапка wrote:If the Registrar BDG eyes gave the results I would be the first to know,I believe my experience)))
YES!! this is the problem , I can not sleep with the thing on the bridge and all the PPC,the sensor works like a clock and adjust the sensitivity as you want.Александр (разработчик) wrote: Uncomfortable to sleep in a mask - that's a separate issue.
Thank you for the positive feedbackТапка wrote:a sensor works like a clock and adjust the sensitivity as you want.
I would not take a ready-made sensors is expensive. There is enough infrared led and phototransistor. Also, as I did in Grimstalker e (schematic diagram of the device is on my second website). This pair is located on diametrically opposite points of the circumference of any finger or on the earlobe (the latter very effectively). Programmatically analyzed (through the integrated in the microcontroller ADC) changes voltage level when the heart beats, count the pulse.Тапка wrote:And we are heart rate monitor - heart rate Monitor BEURER PM20 , cheapest took over 1200 RUB.
And on what principle it works? Why not use included with the wireless unit?Андрей Патрушев wrote:the Most reliable detector is the relaxation of the neck muscles. With a professional, so to say, the studies sleep used it.
The electromyogram.ЗН wrote:AND on what principle it works?
And if you think well, how awful this mouse design in reality will work, and make a homemade won't be perfect.Тапка wrote:Want homemade Novadreamer/grimstalker the sensor from the mouse ( well, compared to grimstalker my amoeba but still)---'ll post tomorrow.
I must say - do it yourself gemorno so that Lucci just buy Grimstalker )))
It is not clear why there are so many sensors, if still present, the motion sensor eye? It one is more than enough to determine the phase of the REM.Косинус wrote:Here's a device being developed Remdetector http://ezoelectro.narod.ru/history1/page1.html
