[0050] Embodiment 1

[0051] like Figure 1 As shown, this embodiment provides an analysis system based on a cockpit display and control layout standard task performance model, including: a parameter input subsystem and a performance calculation subsystem.

[0062] Specifically, Figure 8 As shown, the micro-motion operation parameter input submodule is used to set the hand movement calculation parameters, and the main parameters include the number of various micro-motion operations.

[0063] Among them, Fig. 9 As shown, the display and control fusion element parameter input module includes a display and control fusion degree parameter setting submodule, which is used to input the display and control fusion degree parameters.

[0064] In some implementations of this embodiment, the performance calculation subsystem includes an interface display element performance calculation module, an interface control element performance calculation module, and a display and control fusion performance calculation module.

[0065] Among them, Fig.10 As shown, the interface display element performance calculation module includes a visual prominence calculation submodule, an effort degree calculation submodule, an expectation calculation submodule and a value calculation submodule.

[0066] Specifically, the interface display factor performance calculation formula in the interface display factor performance calculation module is as follows:

[0067] H=h e ·H entropy

[0068] Among them, H is the performance value of the display factor, h e=0.6·d+0.3·p R +1.0·L s is the display coefficient, d is the distribution density, p R is the relative position, L s For logical structure; is the visual entropy, is the amount of attention resources that need to be consumed; To pay attention to the distribution ratio; p sum =Σp i is the total amount of attention resources of the pilot in the domain of interest; p i =Sa-Ef+Ex+Va+4 is the pilot's attention resources in the field of interest; Sa=S·G f , is the visual prominence of the area of ​​interest, calculated by the visual prominence calculation submodule, S is the area level of the AOI area of ​​interest, G f is the gray value difference level of the target information; Ef=Pa is the effort level, Pa is the absolute position; is the pilot's expectation of the domain of interest, which is calculated by the expectation calculation submodule, V AOI represents the number of occupancy times of the interest area, V Total represents the sum of the occupancy times of each area of ​​interest; is the value of the information in the interest domain to the pilot, which is calculated by the value calculation submodule, n is the number of corresponding information elements displayed on the interface, and Ki is the importance score of information i.

[0069] Among them, the distribution density calculation submodule, the distribution density, that is, the total amount of information per unit area, is proportional to the search time, that is, for the same search area, the higher the distribution density, the greater the relative difficulty of the search. The distribution density d is calculated according to the following formula

[0070] d = N / S.

[0072] Among them, N is the amount of information on the display and control interface, and S is the overall area of ​​the display and control area.

[0073] Among them, the relative position calculation module: The relative position calculation module contains calculation functions for 4 kinds of sight line flow orders, and the 4 kinds of sight line flow orders are horizontal-down-up, down-up-horizontal, horizontal-up-down, up-down-horizontal. The corresponding functional relationship is established according to each sight line flow order and the total amount of information.

[0074] Horizontal-Down-Up i ) The position relationship can be calculated according to the following formula:

[0075]

[0076] Down-Up-Horizontal (O j ) The position relationship can be calculated according to the following formula:

[0077]

[0078] Horizontal-Up and Down (O k ) The position relationship can be calculated according to the following formula:

[0079]

[0080] Up and down-horizontal (O l ) The position relationship can be calculated according to the following formula:

[0081]

[0082] The above calculation results are comprehensively calculated according to the following formula to obtain the relative position parameter p R

[0083]

[0084] Among them, the logical structure calculation module: as the number of partition categories increases, the search response time presents a U-shaped distribution. Since the data distribution in the scatter plot is approximately parabolic, binomial regression is performed on the data.

[0085] The functional relationship between the number of partition classifications and the reaction time of searching the target is:

[0086] L s =0.0404N 2 +0.8083N+5.0837.

[0087] Among them, the visual prominence calculation submodule, prominence is a bottom-up factor, which is jointly affected by the visual characteristics of the information itself, such as color, brightness, direction, etc. First, the display interface design parameter data is annotated and exported. The data types include three types of data: area of ​​interest area, foreground color and background color.

[0088] Visual salience is calculated according to the following formula:

[0089] Sa=S·G f .

[0090] Among them, S is the area level of AOI area of ​​interest, G f is the gray value difference level of the target information

[0091] The area level of the area of ​​interest is calculated according to the following formula:

[0092]

[0093] Among them, S i is the area of ​​the current area of ​​interest, S totalis the sum of the areas of the interface regions of interest. When 0 < S ≤ 0.2, S = 1; when 0.2 < S ≤ 0.4, S = 2; when 0.4 < S ≤ 0.6, S = 3; when 0.6 < S ≤ 0.8, S = 4; when 0.8 < S ≤ 1, S = 5.

[0094] The gray - scale value difference level is calculated according to the following formula:

[0095] G f = G o - G b .

[0097] Among them, G o is the current target gray - scale value, G b is the background gray - scale value. When 0 < G f ≤ 51, G f = 1; when 51 < G f ≤ 102, G f = 2; when 102 < G f ≤ 153, G f = 3; when 153 < G f ≤ 204, G f = 4; when 204 < G f ≤ 255, G f = 5.

[0098] The gray - scale value is calculated according to the following formula:

[0099] Gray = 0.299·R + 0.587·G + 0.114·B.

[0100] Among them, R, G, and B are the RGB corresponding color values of the information in the target region of interest to be input respectively. The effort - degree calculation sub - module includes an absolute - position module.

[0101] The effort - degree calculation module. The influence of the layout format factor on visual search is mainly reflected in visual search performance. When the search effort is greater, it shows that the visual search time is longer and the search difficulty is greater, and it is more difficult to maintain task performance. The influence calculation of the effort factor Ef can be obtained according to the following formula:

[0102] Ef = Pa.

[0103] The absolute - position calculation module: The absolute position is the position where specific information appears in the display and control interface. Before modeling, first formulate the absolute - position coordinate coding according to the visual field range. Establish a Cartesian coordinate system with the visual field center of the sitting - position eye - level view as the origin. Then, the A, B, and C viewing areas can be coded in the coordinate system according to the ISO9355 - 2 standard, and the regional range calculation is based on trigonometric functions. The regional boundary is L pThe length and angle are obtained by tan function, and the mapping relationship between the view area and the interface area is established in the display control layout interface using trigonometric functions. Then the absolute position p A It can be represented by the position and area in the interface. If the area of ​​interest is closer to the origin, it means that it is closer to the center of the field of vision and the search performance is higher.

[0104] In order to improve the accuracy of the model, the large partition is further subdivided into 4 small areas according to the quadrant positions of A, B, and C. If the A area is subdivided, the A area can be divided into A1 to A8, and so on. The search reaction time in each partition is calculated by experimental data. In order to highlight the differences in performance of the partitions, the reaction time data in each partition is sorted and converted into discrete level data as shown in the characteristic value table in Table 1.

[0105] Table 2. Table of search eigenvalues ​​for each partition target

[0106]

[0107]

[0108] Since the absolute position Pa is characterized by the position and area of ​​the ROI in the interface, the calculation of Pa can be obtained according to the following formula:

[0109]

[0110] Where Pa is the absolute position, S is the area of ​​the region of interest, and k is the value of the corresponding area in Table 1.

[0111] Specifically, the expectation calculation module: Ex (expectation) is a parameter in the model that describes the expectation of the occurrence of an event. Ex can be quantified in Hertz or the bandwidth of a continuous signal to describe the number of discrete events or the frequency of a continuous signal that occurs within an area of ​​interest (AOI). For example, if there are few events in an area, then the value of Ex will be low, while if there are many events in an area, then the value of Ex will be high.

[0112] In the model, the establishment of the Ex parameter is based on the calculation rules of psychology, which can be used to calculate the suddenness of events. The probability of information generation is evaluated by the subject's cognition, that is, the operator's judgment on the degree of change of information in different areas under the current task. Affected by the frequency of information change and the frequency of scanning, a subjective expectation judgment is generated. The expectation is obtained according to the occupancy frequency of each interest area in the task through the following formula:

[0113]

[0114] Among them, V AOI represents the number of occupancy times of the interest area, V TotalRepresents the sum of the occupancy times of each ROI.

[0115] Value calculation module: Va in the area of ​​interest will depend on its importance to the specific task and the importance of the task in the entire task set. Task importance is the judgement of the importance of the information in the area under the current task. Due to the influence of knowledge and experience, experts need to make different judgments on the value of each visual information area in the task and evaluate the importance of the information. In this study, Va in the area of ​​interest is calculated by the following formula:

[0116]

[0117] In the formula, n is the number of corresponding information elements displayed on the interface, and K is the importance score of the corresponding information.

[0118] The interface control element performance calculation module includes a positioning motion parameter calculation submodule and a micro-operation parameter calculation submodule. The calculation of the task performance calculation module of the interface control element can be obtained according to the following formula:

[0119]

[0120] Where MT represents the calculation result of the positioning motion submodule, t dev Indicates the calculation results of the micro-operation submodule.

[0121] The positioning motion parameter calculation submodule is used to calculate the performance of the arm when it moves to the target position, which can be obtained according to the following formula:

[0122]

[0123] Among them, the micro-operation parameter calculation submodule is used to calculate the performance of finger movement, such as key operation, touch operation, knob operation, etc. The micro-operation parameters can be obtained according to the following formula.

[0124] t dev =Σt move .

[0125] Among them, t move Indicates finger movements.

[0126] The display-control fusion performance calculation module is mainly used to organically integrate the interface display element performance and the interface control element performance, and the calculation results are used as the input of the pilot behavior performance quantitative output subsystem. The display-control fusion performance calculation module can be obtained according to the following formula:

[0127] L = s·(h·H+m·M).

[0128] Among them, L is the quantitative result of pilot performance, s is the display and control integration fusion parameter, h and m are the weights of the performance calculation results of interface display elements and interface control elements respectively.

[0129] The display and control integrated fusion parameter calculation submodule adjusts the display control performance according to the degree of fusion of the display and control interface, which can be obtained according to the following formula.

[0130] s=-0.5127x+0.9635.

[0131] Where s is the display and control integration fusion parameter, and x is the display and control fusion value.

[0132] The pilot behavior performance quantification output submodule takes the result L of the display and control fusion performance calculation module as input and presents the pilot performance quantification result in numerical form, thereby obtaining the pilot behavior performance quantification analysis result based on the cockpit display and control layout standard task performance theoretical model.

[0133] in, Fig.11 The pilot behavior performance quantification output subsystem is shown, which outputs the pilot behavior performance quantification result after obtaining the result input of the display and control fusion performance calculation module.

[0134] in, Fig.12 The flow chart of the element parameter input module of the interface display element is shown. The working process is to first input the visual prominence content parameter, then input the effort content, then input the expectation content parameter, then input the value content parameter.
