a device that allows blind and visually impaired and blind to measure and study the apparent displacement of the sun relative to the earth.this device is equipped with a sound mechanism that allows blind to know exactly the mass of the sun.once the electronic mechanism detects the exact position of the solellle.the sound is the moment when the blind and knew that he had found the exact position at the moment it is soleille read two values on the value sets sail.the angle of the sun, that is to say, the light rays of the sun are central to the surface of the earth and all value determines the angle di (named "angle" in space ", that is to say the.the sun from the north south east and west).this ship can open a door in the science of astronomy for the blind.because it allows us to study the apparent movement of the sun star, with respect to the earth.
