Sensor Hub Question

Hello, 

I wrote this about a year ago, when I had a 645/M, I never got any answers, and still have this question (especially at the new 745 Sensor Hub 6.02 is rolling out)

Can anyone please provide the clueless a couple of sentence on what the Forerunner Sensor Hub does, how it is important, what areas for improvement might be in store for us consumers with Sensor Hub updates?  Thanks.

Anyone?

    It is a "hub" and involved "Sensors."  Anyone?

    Hmm, my curiosity about this software has offended a reader of this forum. Curious. Even more, the person read into my post that I was unhappy about something with this software...the internet can be fascinating.

    BTW: Still hoping that someone with insight into what the "sensor hub" does in our little garmin embedded system will post, I'm curious about it.  Thank you.

    Only answer I could find posted 10 months ago in the F6 forum. 

    "Normally you have a list of different sensors. The sensor hub is probably a daemon or library providing access to them. 

    Sensors in the watch are:

    Acceleration

    Gravity

    Gyroscope

    Rotation vector

    Magnetic field (Compass)

    Temperature

    Stop motion

    Heart rate

    Pressure (Barometer)

    The Kernel normally provides access to them via Industrial-IO (iio) but you need to implement how to talk to them from userspace (watch interface)."

    This is from Wikipedia.  Based on this I'd say the answer above is most likely correct. 

    A sensor hub is a microcontroller unit/coprocessor/DSP that helps to integrate data from different sensors and process them. This technology can help off-load these jobs from a product's main central processing unit, thus saving battery consumption and providing a performance improvement.
