Samsung Electronics Co. has developed a mobile phone that recognizes a continuous movement and carries out the corresponding function, the company said.

With the "3-dimensional movement recognition phone," a user can end an advertising phone call or delete a spam text message by shaking the device twice up and down. Writing a number in the air with the phone will trigger a hot key and result in the automatic dialing of the appropriate number stored in memory.

Samsung said an accelerometer is built in to calculate and plot movements in 3-D space and then carry out commands according to the calculations.

Samsung plans to start mass-producing the movement-controlled phone during the first quarter.

The model, SCH-S310, is the latest technology feat by Samsung, which also recently unveiled the industry's first voice-recognition and voice-to-text models.

Samsung, said to be the world's second largest maker of handsets, said it was a daunting task to develop the sophisticated sensor technology. The company developed a moving algorithm to solve this problem. The technology has also been tackled by global makers IBM and Microsoft, but so far without success.

Officials said the movement-recognition phone can also be used to mimic percussion instruments, such as a tambourine, or to switch songs while listening to music on the model's MP3 player.

Another feature allows the phone to voice simple answers from the user. For example, the phone will respond with a voice message "yes" if the user draws a circle in the air with the phone, or "no," if the user draws an X.

The technology was jointly developed with the Samsung Advanced Institute of Technology, leading to 22 patents at home and abroad.

Officials hope the new phone will provide an alternative to the keypad and touch screen as main input devices for mobile phones. Samsung believes improving the technology, such as the ability to recognize individual handwriting, could also contribute to cellular phone security and authentification. (The Korea Herald)
