Claim:
1. A contact type finger mouse, comprising: a pressure sensor unit configured to detect a pressure generated between a finger and a fixed surface through a plurality of pressure sensors fixed at a lower part of the finger; a signal processing unit configured to determine a movement direction and a movement speed value of a mouse pointer based on pressure values obtained through the detection; and a signal transmission unit configured to generate control data including information on the determined movement direction of the mouse pointer and the movement speed value and transmit the data to an interworking device, wherein the signal processing unit analyzes a distribution of a pressure of a contact area between the finger and the fixed surface and determines the movement direction of the mouse pointer, and wherein the signal processing unit determines whether there is a pressure sensor that obtains a pressure value equal to or greater than a first threshold value through the detection, determines the pressure sensor that obtains a pressure value equal to or greater than the first threshold value as a contact sensor positioned in the contact area between the finger and the fixed surface when there is the pressure sensor that obtains a pressure value equal to or greater than the first threshold value, determines a center of the contact area and a center of gravity of the pressure based on pressure values of the plurality of pressure sensors, determines a direction from the determined center of the contact area to the center of gravity of the pressure as the movement direction of the mouse pointer, and determines the movement speed value of the mouse pointer based on a sum of the determined pressure values of the contact sensors.
