Embodiment
In the ping-pong contest tactical analysis method of the present embodiment, Attribute Association square between Attribute Association matrix diagram and bat in bat
The generation type of the system of battle formations is as follows：
A bat is represented with a big grey block, then the association between clapping is represented with a matrix, such as the institute of Fig. 1~4
Show.
It is assumed that matrix representative is adjacent association of the bat on ball placement between clapping now.For three bat attributes in bat
Incidence matrix between any two, there will be the incidence matrix for representing ball placement (to represent ball placement and batting respectively in row and column
The association of position, ball placement and batsmanship) put in 90 degree, the ball placement attribute of the two matrixes is connected with guide line
Row or column.
Then a digit plate for representing this bat sequence number is placed on 90 degree of corners in guide line, then at another angle
Put matrix (representing the association between batter's box and batsmanship) in the 3rd bat.So either still clapped from clapping
Outside, all incidence matrix identical attribute row or column are all alignment and close, while guide line has connected all bats
Drop point attribute in inside and outside incidence matrix, from left to right, remarkable fluency.
Inside and outside all bats thus Attribute Association is shown according to bat sequence.In order to be best understood from batting falling between displaying is clapped
Incidence matrix on point, we placed billiard table beside matrix, by corresponding matrix ranks with the billiard table that actually represents
Drop point site line gets up, so as to be that the analysis of front and rear bat drop point combination is more directly perceived and familiar.
As shown in Fig. 5~7, tactics view illustrates the tactics (the bat attribute of continuous triple time) commonly used in match.In match
The tactics of appearance can be listed successively in tactics view according to the frequency height used.Wherein a line represents a tactics, design
The icon of three exquisite and easy discriminations is as follows.
Ball placement, half of ping-pong table is divided into 9 grid cell lattice, the batting of this bat of the grid representation of filling falls
Point.The design connects the actual physical scene of abstract data and table tennis.
Batter's box, four icons are devised to illustrate four different batter's boxs.Icon by actual player body
Shape simplifies to obtain, and analysis personnel is felt familiar and directly perceived.
Batsmanship, 11 batsmanships are not easy to use color or other vision channel codings.Therefore, batsmanship is to contract
Display is write, to obtain the balance between readable and distinction.
The legend of icon code provides in view bottom.The frequency and scoring rate of tactical application are indicated on the right of tactics.War
Art can use one kind, clap attribute and show for two or three.By selecting required option to carry out more in drop-down list
Change.User can also change the species of tactics by list of getting off.Such as before selection triple time attack after service tactics, second to the
Four tactics of counter-hiting the opponent's service with a quick smash clapped, the 5th claps later tactics at a stalemate.End user can be filtered by using the player of tactics
Tactics.On the right of each tactics, frequency and scoring rate are shown by bar chart and cake chart respectively.These designs can be rapidly
Help browses and compared tactics.
Whole technical-tactics analyzing associated view presents the ball placement in the bat respectively clapped in the whole match, batter's box and
The distribution of the Attribute Association and tactics of batsmanship.Overall view can continue to browse backward by slider bar.Pass through square
The size and the lightness of color put in battle array, we can see at a glance which clap on which combinations of attributes of appearance and compared with
More, scoring rate is higher, and the tactics view on the right shows the details of the high tactics of utilization rate.
Incidence matrix shows the service of player one bout in certain bout between bat in being clapped in statistical views, in each bat
The association situation of upper attribute.The user for participating in assessing has by observing statistical views and being found to rapidly in the bat of third shot on matrix
Obvious pattern, as shown in Figure 1.Two kinds of colors of the depth represent player two and player one respectively, and third shot is light here, says
Bright third shot is that player one hits.Matrix can see maximum most deep two points difference out of the lower left corner of third shot bat
Long ＆ loop-drives in corresponding, anti-long ＆ loop-drives.When third shot is hit in this competition this means player one, often using arc
Circle technology hits the Road long ball or backhand long ball of other side, and usually score.User observes player two the 4th simultaneously
Clap when responding third shot often using the technology of blocking.
In addition, incidence matrix is also supported to hover between bat in clapping, filter, highlighted function.As shown in Fig. 2 certain ratio
In the statistical views of match, the user for participating in assessing by mouse-over in third shot in the combination of long ＆ loop-drives, now second and third
The incidence matrix of bat, the incidence matrix in third shot, in third and fourth incidence matrix clapped, and Road long ball or loop drive phase
The combination of pass all can be high light.Thus user can be can see backhand long ball by statistical views and be made in three, four bat cooperations
Batter's box and technology, do the exploration of multistep, analysis and judgement.
Finally, statistical views are also supported to merge the continuous function of clapping more.As shown in Figure 3,4, the user for participating in assessing is by skill
Incidence matrix is incorporated into two bats before and after P1, P2 between being clapped in the first to the 4th bat clapped in tactical analysis view, wherein light color
P1 represent the bat that player one hits, dark P2 represents the bat that player two hits.Specifically, matrix is in all bats in P1
First to the 4th clap in the bat of bat that hits of all players one matrix plus and, matrix is first to the 4th in all bats in P2
In bat in the bat for the bat that all players two hit matrix plus and.And matrix is that all players one bat between the bat between P1 and P2
To between the bat of the side of player two matrix plus and.There is the button switched in the lower left corner, can be by P1, P2 location swap.Pass through this
Individual function, user can see the distribution situation of one plus sum.
Tactics view：As Fig. 5 tactics views show the frequency and scoring rate of the service tactics of all players one of bout.
In Figure 5, the user for participating in assessing selects tactics only to be represented by the batsmanship of each bat, most often goes out from batsmanship
The attack after service tactics of existing (coming the first row) are player one (light color) services, and player two splits the long and loop-drive of player one.It is such
Tactical application 15 times, there is a scoring rate close to a quarter.Then user adds drop point in tactics and considered, as shown in fig. 6,
The most normal attack after service tactics for (coming the first row) occur are player one (light color) services from batsmanship and ball placement
To the long ball region of Road half, player two, which splits, grows to backhand long ball and the loop-drive of player one moves Road long ball to.Such tactical application
4 times, there is no a score mistake.Further, user can also add considering for batter's box in tactics, as shown in Figure 7.
To sum up, statistical views efficiently and rapidly help user to position key property related information, and support powerful
Step analysis.
