It is going to be a very innovative usages of the technology as an outcome of the competition. Gesture recognition is not going to be so useful to the text based users, but it will change the way of computing, computers will become you companion, like two deaf persons talking with each other, it will create that kind of scenario.

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.
