How does this “Halograph” thing actually look like? I’d like to record my REM times as well, but haven’t yet found the right hardware. Sleep masks are too uncomfortable, the ZEO is too expensive in the long run (sensor pads need to be replaced after 90 days of use) and normal actigraphy from body movement isn’t accurate enough.
Just slightly thinner and more comfortable than in the picture:
The material contains a silver-based antimicrobial, so it does not need to be washed. But the sensor can easily be pulled out should the need arise. The silver ion technology is currently being used in FDA approved medical devices, which have been deemed safe for human use.
I have been using the same sensor for a good year now with no loss in signal quality.
As far as I understood, the sensor is some kind of accelerometer. I’m wondering how this can catch eye movement – especially when wearing it that much away from the eyes like the lady on the picture. Does it have only one sensor?
Any estimate when this actually becomes available?
It has only one sensor which sits on the temple – an eye-length above and behind one of the eyes. You can feel the pulse there, but it is sensitive enough to pick the heartbeat up from anywhere.
You are right – the image above is better suited to show the position of a halophone. A halograph is worn one step lower, like in this picture:
I have some tight deadlines at my day job right now, but I hope to get a few prototype / beta versions out during the next few moons.
I’m looking forwad to it!
Will it be wireless with Bluetooth?
More like in the Matrix – USB cable!
