14th January 2005 - Samsung Electronics unveiled
the world's first “3D movement recognition”
mobile phone (model: 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.
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 shape 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.
Development of 3D movement recognition technology was
a joint project between Samsung Electronics and the
Samsung Advanced Institute of Technology. The project
has resulted in applications for 22 domestic and foreign
patents and 14 technical papers were presented at leading
academic societies.
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.
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.
Samsung Electronics President Lee Ki-tae says, “Our
new movement recognition technology opens a new chapter
in natural communication. We will continue to work on
technology breakthroughs for mobile phones that make
life more convenient for people.”
Features of SCH-S310
The Samsung Electronics SCH-S310 uses 3D motion recognition
technology for user interface. A “beat box”
can be created that will set the phone apart from others
on the market with music functions.
User interface: 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, with 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 more 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. The phone will also
be able to sense changes in body movement and provide
advice on dieting or other health tips.
The “motion beat box” function enables the
user to select a particular sound from the menu such
as “drum,” “tambourine,”, “scratch”
or “clap.” Then he or she shakes the mobile
phone the beat will be re-created in rhythm with the
motion. This enables the user to keep time with any
tune being played.
With the music performance function, the phone will
being to play music after it is shaken by the user.
The sensors in the phone identify the movement and adjust
the beat accordingly.
Moreover, the Samsung SCH-S310 has a magnetic sensor
built in that serves as a compass.
Finally, the latest mobile marvel from Samsung applies
a “fresh new user interface.” The intenna
slide design comes with GPS, 1.3M-pixel camera, music-on-demand,
and mobile banking capabilities.
