| Title: |
Method for Controlling Light |
| Abstract: |
Provided is a method for controlling light, including retrieving
accelerations along an X-axis, a Y-axis, and a Z-axis with a 3-axis
accelerometer sensor; matching the retrieved accelerations with RGB
values; and transforming the RGB values and displaying a color of the
transformed RGB values. The 3-axis accelerometer sensor retrieves the
accelerations Ax, Ay, and Az along the X-axis, the Y-axis, and the Z-axis
and calculates a velocity Vi along the X-axis, the Y-axis, and the Z-axis
using the accelerations Ax, Ay, and Az, with i denoting directions x, y,
and z, Vi=Vio+Ait expressing a terminal velocity in the direction i, Vio
denoting an initial velocity in the direction i, Ai denoting the
acceleration in the direction i, and t denoting time, thereby allowing
variation of brightness to be controlled in eight modes.
