Samsung has developed a cell phone that can sense movement in three dimensions and respond to those movements by performing actions such as dialling numbers or ending a call.
The SCH-S310's motion sensing system allowed users to, for example, draw a number three in the air to dial a three, the company said.
Shaking the phone twice would end a call or delete a message. Other movement functions programmed into the handset include a sharp move to the right or left to tell the built-in MP3 music player to skip forward or back a track, while drawing a "O" or "X" in the air made the phone say "Yes" or "No" out loud, Samsung said.
The phone is compatible with the CDMA2000 1x cellular system and also includes an electronic compass, a 1.3 megapixel camera and a 262,000-color display.
It measured 99.8mm x 49.9mm x 23.9mm and weighs 110gm, a Samsung spokesperson, Suyeon Chae, said..
Ther phone would go on sale in South Korea in March, Chae said.
The company has yet to decide the price. Its overseas launch is also yet to be decided and will depend partly on how the phone does in the South Korean market.
Samsung has applied for 22 domestic and foreign patents for the motion sensing functions.
Looking ahead, the company said it had developed a number of other functions that may be included on future handsets.Tthese included using the sensor to help reduce blurring caused by camera shake.
Changes in body movement might even be able to trigger the telephone to deliver health advice, Samsung said.
