I guess I'm less worried about the cost than I am about the functionality. I think adding this to the phone is pretty cheap since the speaker and microphone are already there. It would be nice to not get fingerprints on the display anymore, but I could see issues with accidental gestures. Just moving the phone to your ear could cause a recognized gesture. I also wonder how far away this would work. For a TV, it would have to work at 10 to 20 feet away to be useful. This could be very difficult to use for people who talk with their hands. But, I guess it's like all new technologies. We have to get used to it.
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
