From the conference web site

When computing can be done quickly enough, we can change the behavior of humans, of physical systems, and of those physical systems that involve humans. By capturing the right data, delivering it quickly, and shaping effective responses, real-time systems will have a huge impact on every institution, from commerce to manufacturing to government.
