PNI says response time of Sentral depends on the sensors used and comparisons would have to take into account the applicaiton processor being compared. They say more to the point is that Sental gives fast accurate readings with very low power consumption.

Does anyone know what the relative response time would be for a fused sensor set, as opposed to fusing the data on a central CPU? It seems like that type of dedicated attention could raise the responsiveness, particularly for something like a quadcopter. I may have to look into that for one or two projects that I am looking at.

Yes, PNI says they are working with developers to build APIs--Android and Windows8 are both on their list since Sentral is both sensor and platform agnostic.

Yes, you're right, offloading the application processor saves a lot of energy, consuming just one percent of what the application processor would consume running the algorithms itself.

It is also exciting for using only 1% as much power as running the same algorithms on the apps processor. When cool new features are added to mobile devices, there is always the concern that actually using those features puts a big dent in battery life.

Who will be the sensor controller for Android?

I suspect there could be several all using a single Android API.

Yes, motion tracking for VR is critical, since the user is immersed in the experience. And the sensor fusion algorithms are tricky, since they must use the sensors together to correct potemtial errors in any one.

This is very exciting news for areas like virtual reality. I realize that is only a microscopic fraction of the market, but frankly it is hard to get excited about phones with tighter positional tracking. VR on the other hand is very much in its infancy and things like this are easy to visualize having an impact.
