Abstract
Disclosed herein are a mouse with capacitance sensors, a method for manufacturing the mouse and a method for constructing an algorithm for processing an input corresponding to force applied by a user's finger to the mouse. The mouse with capacitance sensors includes a bottom plate having a center point, a plurality of electrodes formed at regular intervals on the top face of the bottom plate and arranged apart from the center point of the bottom plate by an equal distance, a top plate bonded to the top faces of the electrodes and deformed by force applied by a pointing object, and an adhesive layer formed around the top plate and the bottom plate to combine the top plate and the bottom plate. When the pointing object touches the top plate, capacitance sensors are formed between the pointing object and the electrodes to recognize a travel distance, a travel direction and a moving speed of a cursor through the magnitude and direction of force applied by the pointing object.
