Turn AI cameras on your employees and you can measure their productivity. Fly them over the Pacific Ocean and you've got yourself an automated shark-warning system.

What's happening: UC Santa Barbara, with the help of a few AI experts from Salesforce, is using drones to monitor sharks near California beaches in real time.

  • UCSB pilots fly the drones over coastal waters, and the downward-facing cameras feed into software that can recognize sharks in the water.
  • The system — trained, of course, on a large number of aerial shark photos — can differentiate species, and even between sharks of the same type, so that it doesn't double-count Jaws.
  • The shark census is accessible by app, so lifeguards and surf instructors know what's in the water on any given day.
