Based on the technical scheme that embodiment 2 provides, in order to have further understanding to this programme, illustrate with application scenarios comparatively typical in two practical applications below, it should be noted that, soft-key button bar and soft-key button mostly are regular figure, such as rectangle or circle etc., in embodiment provided by the invention, for soft-key button bar and soft-key button for rectangle illustrates.
One, soft-key button bar and the alignment of electromagnetic type antenna plate Founder.
Shown in figure 5, in actual applications, soft-key button bar and the alignment of electromagnetic type antenna plate Founder are a kind of typical installation situation.Four buttons on soft-key button bar are (with 4 for illustrating meaning explanation, with 1,2,3,4 marks, 4 buttons) be equidistantly uniformly distributed between two parties, spacing between soft-key button is b, soft-key button 1 is a apart from the distance of coboundary, soft-key button 4 is similarly a apart from the distance of lower limb, the distance of soft-key button distance button bar dual-side is c, and the distributed data of above-mentioned soft-key button can be drawn by the initial coordinate range computation of default soft-key button bar and soft-key button, repeats no more here.In such cases, A, B, C, D are four summits of soft-key button bar, determine the physical size of soft-key button.Soft-key button bar is arranged on electronic whiteboard correspondence position, is positioned at the upper end of electromagnetic antenna plate.Owing to adopting absolute coordinate system, after therefore installing, adopt the mode that embodiment 2 provides, the absolute coordinate that A, B, C, D are 4 just can determine, and then can determine the position of the soft-key button on soft-key button bar.For button 1.In the ideal situation, only need two the diagonal position coordinates determining soft-key button 1 just passable.Determine that the method for button 1 top left co-ordinate is as follows:
First the actual coordinate of soft-key button bar key point is determined, for the rectangle soft-key button bar shown in Fig. 5, only need the actual coordinate determining 2 points (key point) on diagonal line, other two apex coordinates can be determined, such as the actual coordinate of A point and D point is known, then the coordinate of B point and C point can be determined.Certainly, also can simultaneously using four summits all as key point.Suppose that A point coordinate is (X
a, Y
a), B point coordinate is (X
b, Y
b), C point coordinate is (X
c, Y
c), D point coordinate is (X
d, Y
d).Because now soft-key button bar aligns with electromagnetic antenna plate Founder, therefore have:
X
a＝X
c；Y
a＝Y
b；X
b＝X
d；Y
c＝Y
d。
The then X-coordinate X in soft-key button 1 upper left corner
1, LUfor:
wherein, L
abfor the distance of A point and B point;
Accordingly, the coordinate Y in soft-key button 1 upper left corner
1, LUfor:
wherein, L
acfor the distance between A point and C point.
The rest may be inferred, can determine the lower right corner coordinate (X of button 1
1, RD, Y
1, RD).A rectangle can be determined, the coordinate range of the region that this rectangle covers and soft-key button 1 by the top left co-ordinate of soft-key button 1 and lower right corner coordinate.Same method can determine the coordinate range of soft-key button 2 ~ soft-key button 4.
It should be noted that, the soft-key button quantity that actual soft-key button bar comprises will the schematic diagram that provides of such as Fig. 5 many, and it is various to distribute, but no matter how to distribute, once soft-key button bar determines, the distance at the spacing between each soft-key button so on soft-key button bar, soft-key button distance edge has just been decided, and then just can determine the coordinate range of each soft-key button.
In follow-up use procedure, when after the signal receiving time writer, signal processing can with reference to prior art, is the actual coordinate scope of soft-key button unlike what need contrast.
Two, soft-key button bar is relative to the run-off the straight of electromagnetic antenna plate.
Shown in figure 6, give relative to electromagnetic antenna plate, the schematic diagram under soft-key button bar run-off the straight scene.When using time writer to move the actual coordinate of the key point obtaining soft-key button bar along soft-key button bar edge, just obtain simultaneously soft-key button bar relative to the tilt angle theta of electromagnetic antenna plate and soft-key button bar A, B, C, D tetra-summits absolute coordinates (X '
a, Y '
a), (X '
b, Y '
b), (X '
c, Y '
c) and (X '
d, Y '
d).To obtain button 1 top left corner apex coordinate.
The X-coordinate X ' in soft-key button 1 upper left corner
1, LUfor:
Wherein L '
abfor the distance of A point and B point
The Y-coordinate Y ' in soft-key button 1 upper left corner
1, LUfor:
Wherein, L '
acfor the distance between A point and C point
Same method can determine the apex coordinate position in the upper right corner of button 1, the lower right corner and the lower left corner.Like this, just drawn a circle to approve a rectangular area, this rectangular area is exactly the effective coverage of button 1, i.e. the coordinate range of soft-key button 1 covering.
Same method can calculate effective overlay area of soft-key button 2 ~ soft-key button 5.
