Exploiting ultrasound sensing seems like a smart and affordable way of building control devices...any idea how much these devices would cost? Kris

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.

Valid concerns @daleste...I would love to try a device like this though...no comments can replace the real experience

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
