The PH-S6500 "sports-leisure" phone is equipped with six-axis sensors that enable it to detect movement of the handset, it said.

"When you jog along the street with the phone attached to the waist or wrist, it will show the speed, calories consumed and the distance you have covered," said Koh Eun-Sil, spokeswoman of Pantech said.

"You can also enjoy various games including fishing and auto racing. Holding the phone, you should move as if you were holding the fishing rod out in the stream. You cast the line and hook it," she said.

For auto racing, the holder uses the phone to change the direction and speed of the car on the mobile display, she said.

Pantech began selling the phone in South Korea through SK Telecom, the country's largest mobile carrier.

Samsung Electronics has also said it had developed a mobile phone with a motion-discerning capability. Samsung said it planned to sell the new phone from March.
