Described operating element 30 is a kind of external in this example, and can be set in the device on user's finger 40.Although operating element 30 is that the coordinate of himself position is sent to mobile terminal in this example, but, it will be appreciated by those skilled in the art that, for example, by prior calibration setting or other modes, can obtain operating element 30 self coordinate and user point 40 on projecting plane 20 corresponding relation between indication position, and make mobile terminal also can become user to point the coordinate of 40 indication positions the operating element receiving 30 coordinate conversion according to this corresponding relation.In other examples, described operating element 30 can also be integrated device in the felt pen hand-held user or other similar devices, etc.
As shown in Figure 3, below provide a concrete example of the method that operates projecting plane of the present invention, wherein, comprise following steps:
S1, on the surface of any one projectable, form projecting plane by projection part, show the interactive interface of mobile terminal.Suppose interactive interface place plane setting X-axis, Y-axis; Projecting plane is set X ' axle and Y ' axle in the plane; Point A, B, C, D that interactive interface comprises, the some A ', B ', C ', the D ' that comprise with projecting plane are corresponding.
For example, when S2, operating element order about (being to follow user to point movement) by user and move to several desired locations on projecting plane, send to mobile terminal the report information that comprises desired location coordinate respectively.
Desired location in this example is that projecting plane is borderline a pair of for example, to angle point (putting A ' and B ') arbitrarily, that is, operating element moves to these two and do not report this two coordinates to angle point to mobile terminal to the angle point time-division.The action of the information that turns in a report in this example can be to realize by opening set transmit button on operating element.
S3, mobile terminal, according to the corresponding relation between interactive interface and projecting plane, accurately calculate the relative position coordinates of any one point in projecting plane.Mobile terminal, by the relative position coordinates of any one point in projecting plane, is recorded in the database of a generation, also all relative position coordinates is sent to operating element storage.
Corresponding relation between described interactive interface and projecting plane, comprise: described desired location coordinate, the graphical information (for example its geomery etc.) of interactive interface itself, and the information such as the projector distance (being for example the vertical range on projection part to projecting plane) that obtains of measuring and calculating.
In addition, mobile terminal can be according to the graphical information of interactive interface itself, obtain on interactive interface coordinate (for example having the coordinate of an A, B, C, D) a little, comprise the wherein interface coordinate of interaction area position, and be recorded in database.Mobile terminal can also be according to the corresponding relation between aforementioned interactive interface and projecting plane, obtain on projecting plane on relative position coordinates a little and interactive interface coordinate one-to-one relationship (for example putting the corresponding relation of A, B, C, D and some A ', B ', C ', D ') a little, also deposit in database.
S4, for example, in the time that operating element orders about (being to follow user to point movement) by user again and moves to any point on projecting plane (this point is called to operating position to show differentiation), for example, by opening its transmit button, just can send to mobile terminal the relative position coordinates of this operating position on projecting plane (some C or some D).
S5, this mobile terminal are according to the corresponding relation between coordinate, the interface coordinate of interaction area position on the relative position coordinates of operating element operating position on projecting plane and interactive interface is compared, and whether the correspondence position of the operating position that just can judge operating element on interactive interface belongs to the interaction area on interactive interface.For example, if (put the some C in the corresponding interaction area of C ') while belonging to interaction area, mobile terminal will be carried out the respective handling that interaction area is set.For example, if (put the corresponding not some D in interaction area of D ') while not belonging to interaction area, mobile terminal may be set to the subsequent operation of waiting for from operating element.
Can be further Z ' axle by the direction setting perpendicular to projecting plane.In a preferred example, for as shown in step S2 ~ S3, carry out in initialized process having recorded the database of the relative position coordinates of any one point in projecting plane, can make operating element in the time sending the three-dimensional relative position coordinates of three-dimensional desired location coordinate and operating position, the coordinate figure of accurate X ' axle and Y ' axle is provided, can submit the coordinate figure of Z ' axle to simultaneously, but allow the coordinate figure of Z ' axle to have certain error, for example, as long as the coordinate figure of Z ' axle is in the threshold value of a setting.
Thereby, as shown in Figure 2, projecting plane can be formed on the medium 50 that can both see from tow sides, be for example transparent or semitransparent glass surface etc., and, make mobile terminal in the time of the relative position coordinates of contrast judgement operating position and the interface coordinate of interaction area, also only need accurately to determine X ' axle, whether the position of Y ' axial coordinate indication has corresponding interaction area 11, and can the threshold value based on same judge processing to Z ' axial coordinate value, only need to judge that user operates in certain distance on projecting plane 20 or above projecting plane 20 by operating element, and do not need specifically to determine it is the front (for example positive axis of corresponding Z ' axle) on projecting plane 20 or the operation of for example, carrying out at the reverse side (the negative semiaxis of corresponding Z ' axle) on projecting plane 20, therefore, the double-edged user in projecting plane 20 can be at the enterprising line operate in projecting plane 20, provide abundanter user's operating experience with this.
Referring to step S2, for rectangular projecting plane, in this example by a pair of region that can know this projecting plane to angle point so that calculate on projecting plane relative position coordinates a little; And in order to determine more exactly the region on this projecting plane, can also by preset further require operating element move to another when to angle point, central point or other positions also to the mobile terminal information that turns in a report.

For example, in some examples, can be the point of other positions or other quantity in the region that on border, projecting plane or border is surrounded in advance as desired location point, require operating element in the time moving to these location points, to submit coordinate to.Or, can also be that the line segment of some position in the region that on border, projecting plane or border is surrounded is in advance as desired location section, for example require Boundary Moving one circle of operating element along whole projecting plane, and when mobile, continue to open its switch key and send the coordinate set of mobile route.
Referring to step S3, due to the graphical information of interactive interface, on interactive interface coordinate a little etc., be all the Given information that mobile terminal itself just can obtain by simple process; And projecting plane is generally amplification (or dwindling) form of this interactive interface, on projecting plane a little with interactive interface on have a little an one-to-one relationship.Therefore, mobile terminal is according to the projector distance of the graphical information of interactive interface and measuring and calculating, can calculate the corresponding relation of the coordinate of relevant position on the coordinate of desired location on projecting plane and interactive interface, and then calculate with the relative position relation of desired location according to other points on projecting plane, just can obtain on projecting plane relative position coordinates a little.
Referring to step S5, in the present invention, do not limit the concrete processing that mobile terminal carries out according to coordinate comparison result on interactive interface.Such as, when judging on the operating position of operating element on projecting plane and interactive interface in interaction area that the coordinate of a return push-button matches, and while representing to press the operation of return push-button by opening the transmit button of operating element, mobile terminal is carried out the action of returning to last layer menu, and may correspondingly switch the interface content of projection by controlling projection parts; Other interaction area are that the situation of button is similar with it.Again such as, when on projecting plane, show be certain document time, can also make mobile terminal according to described transmit button open period operating element the motion track on projecting plane, be presented on interactive interface as various beacon information such as ruling, draw a circle, and controlling projection parts form projecting plane on show too corresponding beacon information, this is very convenient in the situations such as document demonstration.
According to actual application needs, when the present invention can be set in the switching each time of the interactive interface showing on projecting plane, all perform step S2 ~ S3, projecting plane relative position coordinates is carried out to an initialization; Also can be just in the time projecting to other surfaces or projecting plane size be changed etc. in situation, just projecting plane relative position coordinates is carried out to an initialization (and at projecting plane invariant position and interactive interface does not carry out initialization while switching), etc.
