Draining our Glass: An Energy and Heat
Characterization of Google Glass by R. LiKamWa et al. 2014
Summarizing the article linked above.
The two main problems with the google glass system is the proximity to the head of the individual and the small battery size. They determine that given this design there are many current applications which are non-viable for running with the google glass. In fact they compare the power usage to that of a smartphone. They then propose a couple changes in order to fix the above problems (Scalable Imaging, Heterogeneous Computing, etc).
So from what I had learned about Google's "Ok Google" platform was that they essentially have just a chip dedicated to just listening for "Ok Google". Does just that ensure that battery life is maintained? Or are there other features that ensure that?
