Abstract
An input device for a finger touch interface includes a magnetic unit worn on a tip of a user's thumb for establishing a magnetic field, at least a first magnetic field sensing unit worn on the tip of any finger except the thumb and at least a second magnetic field sensing unit worn on a segment of any finger except the thumb. The first/second magnetic field sensing unit is used to detect magnetic flux density of the magnetic field so as to generate a corresponding signal as an input instruction.
