Pendant pearl capsule (101-3) is positioned at the cloth capsule that gloves refer to pad of finger; Pendant pearl capsule line-entering hole (101-4) is positioned at the central authorities of gloves facies digitales dorsales manus and cloth capsule rear wall (101-5) intersection; Gloves refer to stretch or in BENDING PROCESS, and magnetic pendant pearl (201) borrows deadweight and naturally away from pendant pearl capsule line-entering hole (101-4), and make front bracing wire (204), back guy (205) is in tensioned state always; What gloves referred to once stretch bends a light path break-make that can cause correlation infrared receiving/transmission diode in I type key sensor module, causes Hall element (206) and magnetic falls once distance between pearl (201) simultaneously, makes the measuring point voltage up-down of correspondence once; In II type key sensor module, shading flaps (301) is vertically stitched solid at the gloves back side by the shading flaps pilot hole (301-1,301-2,301-3) abutting in the gloves back side, turning over groove (302) vertically stitches solid at the gloves back side by the groove pilot hole (302-1,302-2,302-3) that turns over abutting in the gloves back side, turns over the vertical consistency that the longitudinal direction of groove (302) and shading flaps (301) and gloves refer to; The rotor stiff end (301-6) of shading flaps (301) be positioned at turn over groove (302) turn over groove notch (302-5) outward, the billet shape thin slice (301-4) of shading flaps (301) fit loosely in through turning over groove notch (302-5) turn over groove (302) groove in; Along gloves, the rotor free end (301-7) of shading flaps (301) and rotor stiff end (301-6) refer to that genesis analysis is in articulations digitorum manus (304) both sides, turn over turning over groove notch (302-5) and turn over groove cecum (302-6) and referring to that genesis analysis is in articulations digitorum manus (304) both sides along gloves of groove (302); Correlation infrared receiving/transmission diode is centrally fixed on each other and turns in two round tube holes that groove (302) both sides are mutually symmetrical, is embedded in a Hall element at one of these two round tube holes; Gloves refer to stretch in process in the wrong, and the billet shape thin slice (301-4) of shading flaps (301) fits loosely in all the time and turns in the groove of groove; What gloves referred to once stretch bends and can cause a light path break-make of turning over correlation infrared receiving/transmission diode in groove, causes a resistance lifting of turning over Hall element in groove, makes corresponding measuring point voltage up-down once; In displacement probe module, be covered with the gloves back with being affixed before and after multiple magnetic stripe group and form magnetic stripe layer; A magnetic stripe group comprises zero parallel between two magnetic stripe, middle magnetic stripe, strong each one of magnetic stripe, and zero magnetic stripe, middle magnetic stripe, by force magnetic stripe splice along finger tip to the orientation of finger root, front and back with being affixed successively; One runs through gloves that nature divides out, wide, magnetic field intensity is consistent everywhere and perpendicular to the elongate magnetic vertical bar that gloves refer to, be called that rank become magnetic stripe; Be covered with the gloves back with being affixed before and after multiple vitta group and form vitta layer; A vitta group comprises black bar parallel between two, grey bar, each one of white bars, and orientation, front and back that black bar, grey bar, white bars point to thumb along little are spliced with being affixed successively; One runs through gloves that nature divides out, wide, gray scale is consistent everywhere and be parallel to the elongated black and white vertical bar that gloves refer to, is called a rank color change bar; Reflecting light electric diode and Hall element that glue is fixed in position, gloves right hand thumb finger tip section back center with thumb and become outside flat thumb four refer to the backs make two-dimensional movement and produce correspond respectively to X displacement or Y displacement voltage rising edge, voltage drop is along sequence; In displacement probe module, if in the same count cycle, the voltage rising edge counting m that Hall element is corresponding, voltage drop are along being counted as n, the voltage rising edge counting M that reflection type photoelectricity diode is corresponding, voltage drop are along being counted as N, then in this count cycle, X displacement=(m-n) (m+n)/abs (m-n), Y displacement=(M-N) (M+N)/abs (M-N); Abs (m-n) is the absolute value of (m-n), and abs (M-N) is the absolute value of (M-N).
