Abstract:
1. A touchpad using resistive electro-conductive fibers, the touchpad comprising: a plurality of motion detectors arranged in a two-dimensional array with a plurality of rows and columns, each of the motion detectors including: a resistive electro-conductive fiber having a resistance value that varies according to a change in length thereof, the change being caused by contact with a human body part; and a signal generator configured to output a signal corresponding to the varied resistance value, each of the resistive electro-conductive fibers having both free ends captured by the corresponding signal generator, thereby forming a loop; and a signal analyzer configured to analyze the signal output from each of the motion detectors, and to generate a motion signal representing a motion of the human body part in contact with the touchpad corresponding to coordinates in the two-dimensional array.
