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.
