Are there any good gadgets for measuring tilt and emotional stress at the moment on the market?
I was thinking that the quantified-self makers Jawbone and their newest device Up3 would be a contender, or at least with some 3rd party software. But so far I haven't read anything about it.
The only thing I can come up with is Dave Asprey and his Emwave to measure heart rate variablility. That device seems like a hot contender but has got some critique for being psuedo-science.
