Samsung unveils a new cell phone that has the ability to recognize and respond to the motion of its user. The SCH-S310, to be released in Korea in March, allows callers to perform such functions as speed-dial by gesture, such as "writing" a number in the air with the phone.

Shaking the phone twice ends the call or deletes spam messages.

The phone was developed jointly by Samsung Electronics and the Samsung Advanced Institute of Technology. It contains an accelerometer, which detects, calculates and responds to three-dimensional movement.

Samsung said the technology can identify small and rapid movements as well as letters and numbers.

Some analysts, nonetheless, wonder how practical the technology really is.
