[PhysOrg.com] Samsung Electronics unveiled the world's first "3D movement recognition" mobile phone SCH-S310. 'Accelerometer' is built in to accurately calculate and ascertain movement in three dimensional space and then carry out commands according to those calculations.
Mobile phone input devices to date include the keypad, touch screen and voice recognition. In the future, however, 3D movement recognition technology will become an important user interface and revolutionize mobile phone designs and features.
This technology will do away with the need for complex keypads on mobile phones, MP3 players, digital cameras and other handheld products. This will particularly effect the way games are played on a mobile phone. Many functions will be controlled by movement instead of buttons.
