Embodiment
In the method for the invention, when user's hand contacts with contactor control device, pick-up unit can detect user's the effective trigger point of finger on contactor control device, and pick-up unit and trigger point effective in these are at number, position, effectively the mouse instructions that the user sends is judged in the various variations on the triggered time.
See also Fig. 1, its simple schematic diagram for detecting for the trigger point in the present invention.When the user was placed in hand on pick-up unit, action capture device 110 can carry out the acquisition of trigger point to user's hand, and the trigger point 101,102,103,104 that determines effectively to trigger, and 105.Action capture device 110 can include: a motion image pick-up unit, a touch detection device etc.Mouse is also controlled to send the action of mouse instructions with five fingers on hand with the user who coordinates general mouse in trigger point 101,102,103,104, the 105 effective trigger points corresponding to 110 of five fingers of user and action capture devices.
then, action recognition device 120 can be with trigger point 101,102,103,104,105 one by one corresponding to the reference position of coordinate systems 250 of the inner definition of action recognition device 120, be defined as a plurality of trigger point coordinate (x1, y1), (x2, y2), (x3, y3), (x4, y4), and (x5, y5), after narration in, corresponding trigger point, trigger point 101 coordinate is that unified definition is (x1, y1), and corresponding trigger point, other trigger point coordinate is also made the unified definition of same way as with the relevant narration of trigger point after simplifying.Note that coordinate system 250 comprises an origin (0,0), correspondence is positioned at the upper left initial point 150 of user's hand; One first coordinate axis 260 that coordinate system 250 comprises is corresponding to user's hand horizontal direction, that is corresponding to a first direction 160 that is set out by initial point 150, wherein, the first coordinate axis 260 can be regarded as the X-axis on coordinate system 250; One second coordinate axis 270 that coordinate system 250 comprises is corresponding to user's hand vertical direction, that is a corresponding second direction 170 of being set out by initial point 150, and wherein, the second coordinate axis 270 can be regarded as the Y-axis on coordinate system 250.
In one embodiment of this invention, first direction 160 can be mutually orthogonal with second direction 170, and the first coordinate axis 260 and the second coordinate axis 270 also can be corresponding mutually orthogonal, but in other embodiments of the invention, the first coordinate axis 260 and the second coordinate axis 270 also can be not orthogonal, and first direction 160 also may not quadrature with second direction 170.A plurality of trigger points that coordinate system 250 can make by the definition of system user's hand trigger must fall within on coordinate system 250 in as shown in Figure 1 quadrant.
In the disclosed method of the present invention, the most important thing is the selected of reference point, because the selected meeting of reference point directly has influence on each trigger point that the user triggers corresponding to the judgement of left mouse button or right mouse button.Fig. 1 and Fig. 2 disclose the embodiment of the present invention on selected reference point.In this embodiment, with the user and pick-up unit detected a plurality of trigger points middle distance the first coordinate axis 260 the shortest a bit as the reference point of fitting lattice.See also Fig. 2, it is the schematic diagram of the distance relation of each trigger point coordinate and the first coordinate axis 260 in pictorial image 1.In Fig. 1 and Fig. 2, trigger point coordinate (the x3 of the trigger point 103 that user's middle finger triggers correspondence on coordinate system 250, y3) can be used as the reference point of suitable lattice, because between trigger point coordinate (x3, y3) and the first coordinate axis 260 apart from d3 corresponding coordinate distance first coordinate axis 260 compared to other user's trigger point apart from d1, d2, d4 or d5 for the shortest; As a reference point with the trigger point of user's hand forefront in the present invention, then, can carry out each trigger point corresponding to the judgement of left mouse button or right mouse button according to the relative position between reference point coordinate and other trigger point coordinate, and and then judge the mouse instructions that the user triggers.
Because the user is using the customary difference of mouse, therefore may use the finger of varying number and combination to trigger effective trigger point within the different time on pick-up unit, and the mouse instructions that the user triggers also needs to change to judge corresponding to these, conditions such as the quantity of trigger point, effective duration of contact or displacement; Wherein, the variation of trigger point quantity can directly have influence on the decision of reference point, effective duration of contact of trigger point and the mobile kind that can have influence on the mouse instructions that the user triggers.In the method for the invention, comprise the step of carrying out corresponding judgement with regard to the quantitative variation in trigger point.See also Fig. 3 to Fig. 8, it decides the schematic diagram of reference point for the different numbers trigger point of triggering according to user's hand in the present invention.
In Fig. 3, when the user only comes touch detection device with forefinger, make when only being detected a trigger point coordinate (x2, y2) on coordinate system 250, at this moment, trigger point coordinate (x2, y2) and between the first coordinate axis 260 is the distance the shortest with the first coordinate axis 260 in all trigger points at present apart from d2, and therefore, the reference point coordinate namely is decided to be (x2, y2), that is trigger point 102 be decided to be reference point.In like manner, when a trigger point that only is detected be trigger point 101,103,104 or 105 one of them the time, reference point is the trigger point that is detected in trigger point 101,103,104 or 105.
In Fig. 4, the user has triggered effective trigger point that contacts 102 and 103 with the forefinger of the right hand on pick-up unit with middle finger, makes to have occurred comprising trigger point coordinate (x2, y2) and (x3, y3) totally two trigger point coordinates on coordinate axis 250.At this moment, due to trigger point coordinate (x3, y3) and the first coordinate axis 260 apart from d3 than trigger point coordinate (x2, y2) with the first coordinate axis 260 apart from d2 come short, therefore the reference point coordinate is decided to be (x3, y3), that is this moment, trigger point 103 was decided to be reference point.
In Fig. 5, the user is with the thumb of the right hand and the nameless effective trigger point that contacts 101 and 104 and at this moment due to the trigger point coordinate (x4 corresponding to trigger point 104 of having triggered on pick-up unit, y4) be trigger point coordinate the shortest with the first coordinate axis 260 distances on coordinate system 250, so trigger point 104 can be decided to be reference point.
In Fig. 6, suppose the user with thumb, the forefinger of the right hand, triggered pick-up unit with little finger of toe and the trigger point 101,102 that obtains effectively contact, and 105, and obtain trigger point coordinate (x1, y1), (x2 of correspondence, y2), reach (x5, y5).At this moment, trigger point coordinate (x2, y2) with the first coordinate axis 260 apart from short apart from d1 or d5 of d2 compared to other trigger point coordinate and the first coordinate axis 260, therefore, trigger point coordinate (x2, y2) on coordinate system 250 near the trigger point coordinate of the first coordinate axis 260, and determine that accordingly reference point is trigger point 102.
In Fig. 7 and Fig. 8, the diagram user with thumb, forefinger, the third finger of the right hand, triggered pick-up unit with little finger of toe and the trigger point 101,102,104 that obtains effectively contacting, reached 105, and obtain corresponding trigger point coordinate (x1, y1), (x2, y2), (x4, y4), reach the situation of (x5, y5).
With Fig. 7, near apart from d4 than trigger point coordinate (x4, y4) and the first coordinate axis 260 apart from d2 due to trigger point coordinate this moment (x2, y2) and the first coordinate axis 260, therefore trigger point 102 can be decided to be reference point, rather than trigger point 104 is decided to be reference point; But in Fig. 8, short apart from d2 than trigger point coordinate (x2, y2) and the first coordinate axis 260 apart from d4 of trigger point coordinate (x4, y4) and the first coordinate axis 260, therefore as a reference point with trigger point 104, but not as a reference point with trigger point 102.
In other words, when carrying out the detection of trigger point at every turn, be not to be the close together of certain one distance the first coordinate axis 260 between corresponding trigger point coordinate on trigger point 102 and 104 each comfortable coordinate systems 250, and must see the detected result in each each trigger point and decide by end, and determine according to this a reference point.In like manner, when the user triggers mouse instructions with five fingers, distance the first coordinate axis 260 nearest trigger point may not be also the trigger point 103 corresponding to the middle finger of right hand the top, and need according on coordinate system 250 at that time each trigger point judge with the distance of the first coordinate axis 260, and decision reference point at that time accordingly.
Above embodiments of the invention carry out the decision of reference point with the right hand that the user was habitually practised, yet even detect the trigger point that user's left hand triggers, still can use the method for above-mentioned exposure to decide reference point.
After reference point is determined, just can decide each trigger point corresponding to left mouse button or right mouse button according to the relative position relation that reference point and other are not decided to be between the trigger point of reference point, thereby and determine the mouse instructions that the user will carry out.Just general mouse user uses the custom of mouse, left mouse button will occur significantly different from the instruction of right mouse button, therefore, in the method for the invention, judge that by the distance between reference point coordinate and trigger point coordinate and the second coordinate axis 270 in left mouse button or right mouse button, whichever is triggered.
See also Fig. 9, its be pictorial image 1 with Fig. 2 in the schematic diagram of distance of each trigger point on coordinate system 250 and the second coordinate axis 270.In Fig. 9, reference point has been decided to be trigger point 103; When the state of trigger point 104 or 105 changes (when for example hand contacts with contactor control device), due to trigger point 103 and the second coordinate axis 270 apart from the length apart from d4 ' or d5 ' come of d3 ' than trigger point 104 or the 105 and second coordinate axis 270, therefore, user's instruction of sending by trigger point 104 or 105 can be regarded as the mouse instructions that sends by right mouse button; In like manner, when trigger point 101 or 102 is triggered, due to trigger point 103 and the second coordinate axis 270 apart from the length apart from d1 ' or d2 ' come of d3 ' than trigger point 101 or the 102 and second coordinate axis 270, therefore, user's instruction of sending by trigger point 101 or 102 can be regarded as the mouse instructions that sends by left mouse button.
When trigger point 103 (that is reference point itself) also can decide triggering in reference point corresponding to left mouse button or right mouse button according to built-in definition by system.Although the described embodiment of Fig. 9 is described for the hypothesis that the user sends mouse instructions with the trigger point of right finger, when the user sent mouse instructions with the trigger point of left-hand finger, the described embodiment of Fig. 9 still can be suitable for.
General comparatively common mouse instructions comprises clicks (Click) instruction, and click commands comprise click (Right Click) by right key, left button is clicked (Left Click), two key click instructions such as (Double Click).In the disclosed method of the present invention, effectively click commands need to be by a marginal time auxiliary judgment.With regard to general mouse click commands, within extremely short marginal time, arbitrary finger of user is entered the state of this mousebutton of contact by the state of a certain button of touch mouse not, and (that is user's finger is put next mousebutton by lifting again to get back to the state that does not contact this mousebutton, and very fast when leaving this mousebutton), can be regarded as once effectively mouse click commands.In the method for the invention, when a certain trigger point enters by the state that is not triggered the state that is triggered within this marginal time, once more get back to the state that is not triggered the time, can be regarded as the user and send once effectively click commands by the trigger point.Tackle the habit of using mouse in the user, this marginal time can be set as one to two second, but length that should the marginal time also can be done dynamic setting voluntarily by the user.
Moreover, click by right key with two kinds of instructions of left button click and can be judged with the step that the judgement user send mouse instructions with left mouse button or right mouse button according to the step of above-mentioned decision reference point.Please again consult Fig. 6 and Fig. 7, and hypothesis is on coordinate system 250 and within this marginal time, the situation that is not triggered by trigger point 104 shown in Figure 6 (represents with the dotted line circle trigger point coordinate (x4 that is not triggered in Fig. 6, y4)) enter the situation that trigger point 104 shown in Figure 7 has been triggered, enter situation shown in Figure 6 by situation shown in Figure 7 again, produce and form trigger point 104 condition that once effectively triggers within this marginal time.situation with above-mentioned hypothesis, because reference point coordinate in Fig. 6 and Fig. 7 has been decided to be trigger point coordinate (x2 corresponding to trigger point 102, y2), and the trigger point coordinate (x4 of trigger point 104 correspondences, y4) on coordinate system 250 and between the second coordinate axis 270 apart from d4 ' than trigger point coordinate (x2, y2) and between the second coordinate axis 270 is (that is trigger point coordinate (x4 far away apart from d2 ', y4) at reference point coordinate (x2, y2) right-hand), therefore effective triggering of this time trigger point 104 can be judged as that right mouse button is corresponding clicks instruction by right key.In like manner, if above-mentioned effective triggering occurs in trigger point 101 and corresponding trigger point coordinate (x1, y1) thereof, can be judged as the corresponding left button click commands of left mouse button one time.Moreover, if above-mentioned effective triggering occurs in reference point itself, that is when occurring in trigger point 102 and corresponding trigger point coordinate (x2, y2) thereof, can the setting built-in according to system decide and click for what right mouse button was triggered the left button click commands that instruction or left mouse button are triggered by right key.
Method of the present invention is also carried out auxiliary judgement according to the above-mentioned marginal time when determining the mouse instructions of dual click.Trigger the custom of dual click commands with hand motion with the user, the user can knock twice within the marginal time continuously with same finger, and corresponding to above-mentioned coordinate system 250, that is same trigger point is satisfied at least twice condition that effectively triggers within the marginal time.By method of the present invention above-mentioned for reference point decision and the exposure of the triggering determining step of left mouse button/right button, the dual click of judging that can be very fast is the dual click of right button or left button, so locate no longer the judgement of dual click to be given unnecessary details.
In addition, in method of the present invention, except mobile or towing instruction may use finger (that is the trigger point more than two changes) more than two operates, the state that other mouse instructions only has single trigger point in principle can change; Therefore when two state variation more than the trigger point occur simultaneously in mobile or towing instruction situation in addition, can be regarded as insignificant mouse instructions; This moment, all trigger points also can be detected again again, quantity and the position of the trigger point that is triggered with correction, and avoid by this determining insignificant mouse instructions.
Please note, although only enumerate part mouse instructions commonly used in the exposure of the embodiment of the invention described above, but need according to determining that reference point decides left mouse button or right mouse button to be triggered, the embodiment of other mouse instructions that quilt and then decision are corresponding must be considered as category of the present invention.
See also Figure 10, it is the schematic diagram that the method for mouse instructions is decided in disclosed detection trigger point according to the present invention.As shown in figure 10, method of the present invention comprises the following step:
Step 302: detect at least one trigger point that the user triggers;
Step 306: according to the distance of one first coordinate axis on this at least one trigger point and a coordinate system, determine that the trigger point in this at least one trigger point is a reference point;
Step 308: the distance between one second coordinate axis on comparison one trigger point that changes and this coordinate system and the distance between this reference point and this second coordinate axis, to determine the mouse instructions of this mouse instructions as being triggered by a left mouse button or a right mouse button;
Step 310: according to the number of the relative position relation of this at least one trigger point and this reference point, this at least one trigger point, and the trigger point that comprises, this at least one trigger point whether be cancelled within a marginal time and reply again the state that is touched after contacting, determine the mouse instructions that the user triggers.
Step shown in Figure 10 is the summary of above-mentioned narration relevant to Fig. 1 to Fig. 9, therefore at this, step shown in Figure 10 is not given unnecessary details in detail.
Each step shown in Figure 10 and execution sequence are only a preferred embodiment of the present invention, therefore must be considered as category of the present invention for reasonably arranging or make up formed other embodiment on the execution sequence of each step shown in Figure 10.
