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.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
