Samsung introduces ''3-dimensional Movement Recognition'' mobile phone
Samsung Electronics unveiled the first "3D movement recognition" mobile phone, the SCH-S310. An 'Accelerometer' is built-in to calculate and ascertain movement in three dimensional space and then carry out commands according to those calculations.

Sophisticated sensing technology calculates the direction in which the mobile phone is moving as well as its speed of movement. The capability extends beyond the identification of the general locus to include precise recognition of small and rapid movements as well as alphanumeric symbols.

The recognition of moving shapes in 3D space, using only sensors built into a mobile phone, is a daunting task. Samsung has developed and commercialized a moving algorithm to solve this problem.

To date, movement sensors in mobile phones have been limited to slope calculations and applied to some games and bio-related features. However, the SCH-S310 can recognize continuous movement in 3-dimensional space.

The company says that 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.

One of the user interface features is the daling by gesture: the user can "write" the number "three" in the air. The mobile phone can read this movement and then dial "3." Shaking the phone twice will conclude a call or delete spam messages.

The user can draw a "O" or "X" in the air with the phone, which will recognize it and respond with a voice message "yes" or "no." Move the phone sharply to the right and the selection on the MP3 play function will move to the next tune on the list; move it to the left, and the selection will back up one number.

Moreover, Samsung has already developed movement-controlled functions that will be adopted on later models. These include switching from landscape to portrait when shooting video or snapping a still picture, or preventing the picture from becoming blurred from hand movement. Games will be played by moving the phone up, down, right or left, instead of pressing buttons.
