Embodiment

, be first embodiment of the designed finger-moving type pointer input media of the present invention at first referring to shown in Figure 1; It includes a body 10 and the bottom is provided with a pedestal 20, be provided with in pedestal 20 places and can detect the height and position detector 30 that it vertically is the Z axial translation, be provided with in body 10 1 ends and can detect the planimetric position detector 40 that it laterally is X, Y-axis displacement, aforesaid detector can use infrared ray, ultrasound wave, CCD (Charge-Coupled Device) or CMOS technology such as (Complementary Metal OxideSemiconductor) for it; In the present embodiment then as an illustration with CCD (or CMOS) detector; Can on a use plane, be formed with a sensing region 50 via

aforesaid detector

30,40, so that in this sensing region 50, carry out the acquisition action of image feature.

Cooperation referring to Fig. 1 to shown in Figure 3, when being used in desktop PC, user's hand 60 and point 61, be fully the position within sensing region 50; After the step via pick-up image 70, distinguish through image identification unit 71 more whether look is a hand image; Afterwards, obtain a characteristic image of 3 planimetric positions such as user's hand both sides and finger again by an image feature acquisition unit 72, and via a planimetric coordinates compilation unit 73 and planimetric coordinates comparing unit 74 with the pointer position of this characteristic image corresponding to computer screen; So after user's hand 60 moves in sensing region 50, planimetric coordinates comparing unit 74, can analyze, compare a shift position variable quantity of image, can make a cursor move driver element 75 generations one corresponding computer cursor and move signal 76 to computing machine.

Again, point 61 actions this moment after the step of pick-up image 80, look through distinguishing of image identification unit 81, and after the auxiliary affirmation of the finger fingertip position of image identification unit 81, promptly can obtain the characteristic image that the user points a height and position of 61 by image feature acquisition unit 82; When finger 61 enforcements upper and lower moving once, the characteristic image of this height and position, after moving variable quantity via the analysis of a height and position coordinate compilation unit 83 and height and position coordinate comparing unit 84, comparison one height and position, can make a keying signal driver element 85 produce a keying signal to computing machine 86.Wherein, this keying signal can be set at the left button signal of a mouse under most situation.
