Thinking what the hell on earth that means !!! well don't bother your brain horses to much as I am going to tell you just that.
It's Sony's Smile Shutter tecnology, which I recently became aware of through Tv commercial. In India, this feature was first appeared in HDR-CX12 camcorder which was launched in August for about $900.

Smile shutter is built around the intriguing notion that the camera will automatically snap a picture the instant your main subject cracks a smile or grin without having to press the photo button. Now no need to wait for your subject to smile. But there is still a problem which this technology don't take care of is how to make your subject laugh. Well jokes apart.... this concept certainly faced a lot of problems and had received a cold response from the industry. The camera is more likely to detect a broad smile when your teeth are showing. Wonder how the camera tackles the babies smile with no teeths. Smile-detection accuracy also rises, if your subject narrows his or her eyes.
The one big drawback is that one can't take picture manually if the camera goes into this smile mode.

But whatever they say I think the concept is appealing and just needed to look in a more practical way.
