Track detection device and track detection method thereof

A track detection method for a track detection device, the track detection device comprising:

• a hollow insulating spherical housing comprising an inner surface;
• a plurality of electrostatic induction units embedded within the insulating spherical housing and evenly spaced around the center of the insulating spherical housing;
• a charged ball moveably attracted to the inner surface of the insulating spherical housing, wherein a static induction is generated between the charged ball and the electrostatic induction unit when the charged ball rolls along the inner surface at a portion of the insulating spherical housing where the electrostatic induction unit is embedded, thus the plurality of electrostatic induction units generate electrical signals;
• and
• a processor electrically connected to the plurality of electrostatic induction units, and configured for detecting a track of the charged ball moving inside the insulating spherical housing according to the electrical signals, the method comprising:
• the processor scanning the wires of the electrostatic induction units to determine which wires that have current flowing therethrough;
• the processor indexing corresponding location data of the determined wires of the electrostatic induction units according to pre-set location data of the electrostatic induction unit stored in a memory;
• and
• the processor determining a track of the charged ball moving inside the insulating spherical housing according to the indexed location data.
