Much has been said recently on off-loading computations
from the phone. In particular, workloads such as speech
and visual recognition that involve models based on “big
data” are thought to be prime candidates for cloud processing.
We posit that the next few years will see the arrival
of mobile usages that require continuous processing
of audio and video data from wearable devices. We argue
that these usages are unlikely to flourish unless substantial
computation is moved back on to the phone. We outline
possible solutions to the problems inherent in such a
move. We advocate a close partnership between perception
and systems researchers to realize these usages.
