The audience gathers at CNET's "The Next Interface: You" panel, an inside look at body-controlled technology and the future of the interface.

CNET's Brian Cooley (far right) and Lindsey Turrentine (second from right) host a conversation with panelists (from left to right) Michael Buckwald, CEO of Leap Motion, makers of 3D gesture control technology; Matt Rogers, VP engineering at Nest, makers of the connected, intelligent thermostat; and James Park, CEO of Fitbit, known for its wearable personal activity monitor and now the Fitbit Flex.

During the panel, CNET's Brian Tong gave live demos of various body interface tech. In this picture, he checks out a brain-sensing headband from Muse with Interaxon founder Ariel Garten.

Michael Buckwald, CEO of Leap Motion, says he's looking forward to the day when he doesn't have to go to the doctor's office anymore -- instead the smartphone can detect if something's wrong based on how you're walking, and so on. Fitbit's James Park agrees, saying that if you collect this data and present it to your doctor, it's pretty informative about how you've been living your life. It would help the doctor better diagnose you.

CNET's Brian Tong tries out a version of Fruit Ninja that lets players slice fruit using eye controls.

Leap Motion CEO Michael Buckwald says the developer community is the most important thing to Leap. They create things that help people use Leap in new ways, he says.
