With adjustment feasibility；Analog record view uses icon to show analog record, while clearly showing every analog record
Simulate effect；View is explained in simulation, shows the technique variation that front and back two is clapped after adjusting a certain bat.
As shown in Figure 1, each node in dendrogram indicates current kinetic person's name or classification by a circle.Not
In the original state for clicking any one, all target sportsmen are horizontally arranged in first layer, and circle color is in black.It clicks
After selection target sportsman, the selected circle of first layer becomes dark.The second layer and third layer are opponent's information in dendrogram,
Circle becomes light color after clicking selection.Total winning rate of target sportsman uses percentage tag representation, is placed below circle, and
Use dark as background.
The table tennis analysis personnel for participating in assessment are interested in the match of player one, therefore in the first layer of dendrogram
It is middle to click the circle for representing player one, select player one as target sportsman.At this point, the circle for representing player one becomes deep
Color, dendrogram show the second layer, respectively left hand type sportsman and right handed sportsman.Analysis personnel, which click on, represents left hand
The circle of type sportsman and right handed sportsman, the circle after selection become light color.Analysis personnel observe that rapidly player one is bright
The case where aobvious and right handed sportsman fight, is more.Therefore, the match of analysis personnel selection player one and right handed sportsman are made
For the source data of sunykatuib analysis, it is further analyzed.
As shown in Fig. 2, all tactics that player one uses in the selected match of analysis personnel are presented in tactics statistical views.Point
The tactics that analysis personnel use player one in attack after service section are interested, therefore click bout phase tag, preferential to select
The tactics used in 1-3 bat of player one are further checked and are screened.Batsmanship is mostly important one of bat attribute,
Therefore, analysis personnel are switched to the tactics that batsmanship attribute comes in watch list.Analysis personnel are further according to scoring rate pair
All tactics in list are ranked up, and are dragged slider bar and screened the tactics that all utilization rates are more than or equal to 1%.Tactics at this time
Only it is left 4 class tactics in list.Analysis personnel observe last a kind of tactics in list (reverse rotation service, chops the chop, loop drive)
Utilization rate highest but scoring rate it is minimum.Analysis personnel are it is thought that one can be improved the breach of one winning rate of player.Therefore,
Analysis personnel click the tactics and further explore.
As shown in figure 3, the statistical distribution that the bat of tactics selected by analysis personnel is presented in view is explored in simulation.Analysis personnel are uncommon
Ball placement attribute by adjusting the tactics is hoped to improve the winning rate of player one, therefore, analysis personnel selection batsmanship and
Ball placement attribute, thus to obtain the statistical distribution of batsmanship and ball placement in selected tactics.
As shown in figure 4, analysis personnel begin to use analog record view to carry out simulation trial.Firstly, analysis personnel click
It generates button and checks three highest analog records of winning rate.Analysis personnel observe rapidly the 3rd adjustment clapped that player one provides
Effect is clapped significantly better than the 1st, caused by thus conjecture may be due to that can cope with the engineering feasibility of service bat excessively.In
It is that analysis personnel add two analog records respectively, the 3rd remaining two kinds of adjustment option of bat in view is explored into simulation and is added respectively
(batsmanship is loop drive, and ball placement is respectively forehand clear and Road long ball) is added in analog record.Analysis personnel see
Existing 5 analog records in analog record view are examined, ball placement is backhand long ball in the 3rd bat of discovery and batsmanship is arc
The adjustment scoring rate for enclosing ball is lower, but it is relatively high to adjust feasibility；The 4th article of simulation of the adjustment is only carried out in analog record simultaneously
Record can obtain relatively significant winning rate and improve, and it is relatively high to adjust feasibility.Therefore, in 5 simulations attempted,
Analysis personnel think that this simulates most worthy, can be applied in the daily workout and strategy of game adjustment of player one.
In order to further appreciate that the process interpretations of Adjusted Option, analysis personnel click the 4th article of simulation in analog record view
The adjustment that player one provides in record the 3rd is clapped, the process interpretations of the Adjusted Option are presented on simulation and explain in view.Such as Fig. 5
Shown, analysis personnel have found in explaining view, and the 3rd transfer arrow for photographing the 5th bat obviously compares the 3rd transfer for photographing the 4th bat
Arrow is wide.That is, when the 3rd claps adjustment, being affected maximum is the 5th bat in the current influence for clapping to subsequent bat.
Personnel are analyzed simultaneously observes that the bat technology of the 5th bat uses in distribution, player one uses the probability highest of quick attack technology, therefore,
The loop drive technology that the 5th meeting of the bat maximum probability that player one provides directly uses quick attack technology cooperation the 3rd to clap carries out continual attack.Root
According to table tennis domain knowledge, quick attack technology is a kind of offensive technology, thus can more be shown really using quick attack technology and
Easy insight promotes the final winning rate of player one.
In order to know how that just player one can be made, which to clap the 3rd, more to be fallen with the backhand long ball that loop drive technology gets to opponent
Attention has been put into the 1st bat and the 2nd and clapped by point, analysis personnel.Analysis personnel observe rapidly the 2nd transfer for photographing the 3rd bat
The transfer arrow that arrow obviously photographed the 3rd bat than the 1st is wide, it follows that the 2nd bat is affected to the 3rd bat generation.Therefore, divide
The bat technology that analysis personnel observation the 2nd is clapped observes the icon depth discovery of every batsmanship using distribution, real to a greater extent
The key for the adjustment that existing player 1 the 3rd claps is in the 2nd bat more using the technology of chopping the chop.Analysis personnel further click on the 2nd
The icon for technology of chopping the chop in bat check clap in technology correlation situation, discovery use chop the chop technology when, the ball placement of the bat is big
Part is distributed in half long ball of long ball and backhand, illustrates to take the technology of chopping the chop by ball impact to half long ball of long ball and backhand as opponent
When ball placement, player one can more easily be got to ball on the backhand long ball ball placement of opponent using loop drive technology.
