The gang has discussed driver monitoring on many past shows, but like much of the mobility tech media we don't always give this topic the attention it deserves. That changes this week, as Ed and Alex welcome Colin Barnden of Semicast Research to the show and grill him with questions about the technology that keeps drivers in the loop. Whether you're curious about where camera DMS comes from, how it works, who develops it or where it's going as a business, Barnden (and this episode) has the answers you seek.
