The special time that sets according to switch 14 or receive number of times, make radio circuit 13 in different time, receive in turn main induction signal and secondary induced signal, then by radio circuit 13 the major and minor sensor circuit 22,23 that main induction signal and secondary induced signal are sent to trajectory retrieval device 20 is in turn received again, to judge the position of input media 10 on trajectory retrieval device 20.

In addition, input media 10 of the present invention is not defined as the structure of digital pen or other forms of a stroke or a combination of strokes, and it also can be designed to a mouse structure with input media 10.As shown in Figure 3, be the synoptic diagram of input media on the trajectory retrieval device of the 3rd embodiment.Its embodiment and aforesaid embodiment are roughly the same, below only are illustrated with regard to different locating.Input media 10 can be a mouse structure (such as wire mouse or wireless mouse), and is respectively arranged with mutually main coil 11 and secondary coil 12 arranged side by side in input media 10 inside.And make main coil 11 and secondary coil 12 be electrically connected at respectively radio circuit 13.

So, the user can grip input media 10 in 21 movements of the workspace of trajectory retrieval device 20.At this moment, the main induction signal that produces of main coil 11 can be transferred to main induction circuit 22 by radio circuit 13.Same, the secondary induced signal that secondary coil 12 produces also can be transferred to secondary sensor circuit 23 by radio circuit 13.Thus, the user is when operated input device 10 (such as wireless mouse), but radio circuit 13 synchronized transmission main induction signals and secondary induced signal are to major and minor sensor circuit 22,23, again main induction signal and secondary induction news are converted respectively to a master site signal and a secondary position signalling (for example with filtering (filter) mode), judge the travel track of input media 10 on trajectory retrieval device 20 with this.

In addition, as shown in Figure 4, be the synoptic diagram of input media on the trajectory retrieval device of the 4th embodiment.Its embodiment and aforesaid embodiment are roughly the same, below only are illustrated with regard to different part.In the present embodiment, also comprise a switch 14 (Swich) in the input media 10 (such as mouse structure), be electrically connected at respectively main coil 11 and secondary coil 12.And make the main induction signal that main coil 11 produces the predominant frequency section and the side frequency section of the secondary induced signal that produces of secondary coil 12 overlapped.

Therefore, can be by the mode of switch 14 with one after the other, in different time, main induction signal or secondary induced signal are sent in the radio circuit 13 in turn, then by radio circuit 13 the major and minor sensor circuit 22,23 that main induction signal and secondary induced signal are sent to trajectory retrieval device 20 is in turn received again, to judge the travel track of input media 10 on trajectory retrieval device 20.

As shown in Figure 5, export the method flow diagram of rotating signal for the input media of the two inductive coils of tool.According to the structure of each embodiment of above-mentioned input media, all can be applicable to the method flow diagram of Fig. 5: at first, step S210 sends the main induction signal with main coil 11, and secondary coil 12 sends secondary induced signal; Step S220 in a very first time, receives main induction signal and secondary induced signal with trajectory retrieval device 20, and main induction signal and secondary induced signal is converted to one first master site signal and one first secondary position signalling; Step S230 at one second time rotation input device 10, receives main induction signal and secondary induced signal again with trajectory retrieval device 20, and main induction signal and secondary induced signal are converted to one second master site signal and one second secondary position signalling; Step S240, compare the first master site signal and the second master site signal, and compare the first secondary position signalling and the second secondary position signalling, and make the trajectory retrieval device export rotating signal to an electronic installation, electronic installation is according to the corresponding action command of carrying out of rotating signal.

Be the mode signal output of clearer description sense of rotation, special describe in detail with Fig. 6 and Fig. 7, and can use among each embodiment such as Fig. 1 to Fig. 4, but be not limited with aforementioned each embodiment.Wherein, Fig. 6 and Fig. 7 are all the synoptic diagram of the sense of rotation of the input media of judging the two inductive coils of tool.X shown in the figure, Y namely represent X-direction and the Y direction in the two-dimensional coordinate, and with the nib O of input media 10 intersection point as X-axis and Y-axis, and X-axis and Y-axis marked off first quartile (+, +), the second quadrant (, +), third quadrant (,-) and fourth quadrant (+,-).Main induction signal and secondary induced signal that main coil 11 and secondary coil 12 are sent convert respectively the first master site signal A and the first secondary position signalling B to.Judge the first master site signal A (hereinafter to be referred as the A point) and the position of the first secondary position signalling B (hereinafter to be referred as the B point) between all quadrants with this.

When user's rotation input device 10, can nib O as reference point, or with the mid point between main coil 11 and the secondary coil 12 as reference point, so that the A point moves to A ' point (namely representing the second master site signal A '), the B point moves to B ' point (namely representing the second secondary position signalling B ').If the A point moves to A ' point, and the B point is when to move to B ' order be direction ordinal shift by first quartile → fourth quadrant → third quadrant → second quadrant (as shown in Figure 6), then trajectory retrieval device 20 judges that input media 10 rotates along a clockwise direction, export a dextrorotation rotaring signal to electronic installation (not illustrating) with this, and then the control electronic installation switches to first mode.

If the A point moves to A ' point, and the B point is when to move to B ' order be direction ordinal shift by first quartile → second quadrant → third quadrant → fourth quadrant (as shown in Figure 7), then trajectory retrieval device 20 judges that input media 10 is along a counterclockwise rotation, export one with this and be rotated counterclockwise signal to electronic installation (not illustrating), and then the control electronic installation switches to the second pattern.

Be understandable that when input media 10 rotation, trajectory retrieval device 20 can judge merely that also the A point moves to the X-axis of A ' point, the changes in coordinates of Y-axis, and judges that the B point moves to the X-axis of B ' point, the changes in coordinates of Y-axis.Though since A point the amount of movement of X-axis and Y-axis must with amount of movement " identical " and the moving direction " on the contrary " of B point in X-axis and Y-axis, so trajectory retrieval device 20 oneself can judge that input media 10 carries out a clockwise or action that is rotated counterclockwise.For example, the A point at the coordinate system of Y-axis from large to small, relative B point then represents clockwise spinning movement when the coordinate system of Y-axis changes from small to big.

Thus, by rotation input device 10 on trajectory retrieval device 20, judge the sense of rotation (such as clockwise direction or counter clockwise direction) of input media 10 with this, and then export a pair of clockwise rotating signal or the corresponding anticlockwise rotating signal of answering to electronic installation, allow electronic installation carry out an action command according to the signal correspondence of sense of rotation.For instance, when input media 10 turned clockwise, the viewing window pictures that can control electronic installation (such as computer) clockwise rotated (namely carrying out first mode).When if input media 10 is rotated counterclockwise, then can controls viewing window pictures and rotate counterclockwise (namely carrying out the second pattern).

Yet this is embodiment explanation, and is non-in order to limit claim of the present invention.It also can with the clockwise or counterclockwise direction of input media 10 rotations, come the corresponding action command of controlling electronic installation, including, but not limited to the function of amplifying (zoom in) or dwindling (zoom out) such as viewing window pictures.Or the target in the clear view screen picture (object), for example target can be the 3D model that application (such as mapping software) is described, and rotates with the angle that the sense of rotation of input media 10 comes corresponding control 3D model to carry out 360 °.Only need with the dextrorotation rotaring signal and be rotated counterclockwise signal to come operating electronic devices to carry out the switching of first mode and the second pattern, or the action command of carrying out a corresponding rotating signal gets final product.

Moreover with the clear mode signal output of describing another kind of sense of rotation of another embodiment, the spy describes in detail with Fig. 9 and Figure 10, and can use the embodiment such as Fig. 8, but not as limit.Fig. 9 and Figure 10 are all the synoptic diagram of the sense of rotation of the input media of judging the two inductive coils of tool.X shown in the figure, Y namely represent X-direction and the Y direction in the two-dimensional coordinate.In the present embodiment, the the first master site signal A that is produced with the main coil 11 of input media 10 is as reference point, or first master site signal A be positioned at the intersection point of X-axis and Y-axis, and X-axis and Y-axis marked off first quartile (+, +), the second quadrant (,+), third quadrant (,-) and fourth quadrant (+,-), and the first secondary position signalling B that secondary coil 12 produces can make a swing offset with respect to the first master site signal A.

When user's rotation input device 10, the first master site signal A that can main coil 11 is as reference point, and namely the A point maintains static, so that the B point moves to B ' point (namely representing the second secondary position signalling B ').If the B point moves to B ' order when being direction ordinal shift by first quartile → fourth quadrant → third quadrant → second quadrant (as shown in Figure 9), then trajectory retrieval device 20 judges that input media 10 rotates along a clockwise direction, export a dextrorotation rotaring signal to electronic installation (not illustrating) with this, and then control the electronic installation switch mode or carry out specific action command.

If the B point moves to B ' order when being direction ordinal shift by first quartile → second quadrant → third quadrant → fourth quadrant (as shown in figure 10), then trajectory retrieval device 20 judges that input media 10 is along a counterclockwise rotation, export one with this and be rotated counterclockwise signal to electronic installation (not illustrating), and then control the electronic installation switch mode or carry out specific action command.

It should be noted that especially the first secondary position signalling B that the user also can secondary coil 12 as reference point, the first master site signal A of main coil 11 then the relative first secondary position signalling B is rotated; Because the mode of judging is identical, therefore do not discuss separately.

Certainly; the present invention also can have other various embodiments; in the situation that does not deviate from spirit of the present invention and essence thereof; those familiar with ordinary skill in the art work as can make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
