Personally, I think being well rounded, as in humanities and language skills in addition to strong technical skills, leads to better designs than does just technical skills alone. It helps by putting design into a social / application context.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
