Cursor control device

A cursor control device comprising:

• a housing;
• a first capacitor comprising a first stator plate and a first rotor plate, the first stator plate being movable relative to the first rotor plate;
• a second capacitor comprising a second stator plate and a second rotor plate, the second stator plate being movable relative to the second rotor plate, the second stator plate and the second rotor plate of the second capacitor being substantially perpendicular to the first stator plate and the first rotor plate of the first capacitor;
• a first capacitance measurement unit electrically connected to the first capacitor to measure the capacitance of the first capacitor;
• a second capacitance measurement unit electrically connected to the second capacitor to measure the capacitance of the second capacitor;
• and
• a processor to analyze acceleration and duration of the changes in capacitance to ascertain movement direction and distance of the cursor control device according to the capacitance measured by the first capacitance measurement unit and the second capacitance measurement unit, when the capacitance between the first stator plate of the first capacitor and the first rotor plate of the first capacitor or between the second stator plate of the second capacitor and the second rotor plates of the second capacitor changes.
