[0060] Specifically, the experimental data is an Excel file.

[0061] Preferably, this embodiment designs two typical ambient lights (weak light environment and strong light environment). The 20 dimming gears required for the experiment are set in advance. The weak light settings are 0Lx, 2Lx, 4Lx, 8Lx, 16Lx, 32Lx, 64Lx, 128Lx, 256Lx, and 512lx; the strong light settings are 1000lx, 2000Lx, 3000Lx, 4500Lx, 7000Lx, 10000Lx, 15000Lx, 22000Lx, 34000Lx, and 51000Lx.

[0062] Optionally, in the design of this embodiment, the experimental data may be used to establish an adaptive dimming model for a display, or to optimize an existing adaptive dimming system, or to verify whether the dimming system meets usage requirements.

[0063] refer to Figure 2 The dimming experiment computer 1 is a laptop computer used to install the dimming experiment software and record, store and export the experimental data. The dimming experiment touch display 2 is a 20-inch × 8-inch LCD full-color touch screen display used to display the dimming experiment related content and dimming operations. A strong light sensor is installed at each of the four corners of the display, and two low light sensors are installed on the upper edge of the display to collect the illumination at the display position; the simulated light environment light source 4 is composed of 10 × 10 light source modules and is arranged on the roof of the laboratory (connected by a series of power cords, mechanical components, etc.). The ambient light control computer 3 is a desktop computer used to install the ambient light control software.

[0064] Furthermore, the software includes a set of dimming experiment software (installed on the dimming experiment computer 1, and the experiment-related information is displayed on the dimming experiment touch display 2) and a set of ambient light control software (installed on the ambient light control computer 3). The above software is used to achieve the following functions:

[0065] 1) Adjust the display brightness

[0066] ① Provide a brightness adjustment slider for the subject to adjust the brightness (touching the slider can quickly increase or decrease the display brightness).

[0067] ②Record the brightness value adjusted each time.

[0068] 2) Test function

[0069] ①Display the test questions and ask the subjects to click on a specific location on the screen.

[0070] ② Determine whether the subject clicked the correct location.

[0071] ③Record the test results of ② above.

[0072] 3) Data export

[0073] ①Export the brightness adjustment records and test records.

[0074] Specifically, the software algorithm logic:

[0075] 1) Initialization

[0076] ① Initialize the brightness record list brightness_records and the test record list test_records.

[0077] ② Load the test question data, including the question number and the coordinates of the correct answer.

[0078] ③ Initialize the user interface, including the brightness adjustment slider, test area, question display label, test result label, start test button and export data button.

[0079] 2) Brightness adjustment

[0080] ①Users can quickly adjust the display brightness through the slider.

[0081] ② Each time you adjust the brightness, get the value of the slider as the brightness value.

[0082] ③Record the current timestamp and brightness value to the brightness record list.

[0083] 3) Test operation

[0084] ①Display the current question and prompt the subject to click the correct position on the screen.

[0085] ② After the subject clicks the screen, the click coordinates and current timestamp are obtained.

[0086] ③ Determine whether the subject clicked the correct location.

[0087] ④Record the test results in the test record list.

[0088] 4) Data export

[0089] ①The user clicks the "Export Data" button and selects the save path.

[0090] ② Export brightness and test records as a CSV file; this file type can be used to store simple tabular data for subsequent processing and analysis. Many tools, such as Excel, Google Sheets, and database management systems, support importing and exporting CSV files, making data manipulation easier.

[0091] refer to Figure 2, software partitioning function. The dimming experiment software can realize the partition display function of the dimming display screen and the touch function of screen information block display. The software divides the display screen into three display areas: left, center, and right. The display content of each left and right area can be set by yourself, usually related to the experimental content. The center area is the experimental operation area, which is used to display experimental related data and for subjects to perform dimming experiment operations. From top to bottom, it includes 7 sub-areas:

[0092] The first subarea displays the experiment name;

[0093] The second sub-area displays the ambient light value and lighting angle;

[0094] The third sub-area displays the ambient light illumination values ​​collected by the low-light sensor and the high-light sensor;

[0095] The fourth sub-area is the experiment start and end operation area, where "Start Dimming" and "Record Data" are arranged. After the subject touches "Start Dimming", he touches the brightness quick adjustment button, and then touches "Record Data" after adjusting. This sub-area also displays the brightness value adjusted by the subject;

[0096] The fifth sub-area is equipped with a brightness quick adjustment button (i.e., a green slider in the fifth sub-area). The subject can quickly increase or decrease the display brightness by touching the button (adjusting the display brightness from the lowest 0.5 cd / m 2 Up to 1050cd / m2 for monitors 2 Less than 0.1 seconds);

[0097] The sixth subarea is equipped with a brightness fine-tuning knob, and the subject touches the fine-tuning knob. The adjustment button can be used to slightly reduce or increase the brightness of the display (each click adjusts the amount by 2cd / m 2 );

[0098] The seventh subarea displays the object blocks that the subjects were required to search for and touch, as well as information about the experimental test content. The experimental software defines the on-screen display information as several object blocks and assigns them different numbers. Each object block can be touched. This is to test whether the subjects can accurately identify the information they are required to search for and touch after adjusting the brightness. The software automatically records the object block number touched by the subject and the object block number displayed in the seventh subarea. If the two match, the adjusted display brightness value is recorded. If the two differ, the software automatically prompts to retest until the software recognizes them as identical.

[0099] Preferably, the ambient light source control software can realize on-demand adjustment of the ambient light brightness to meet the dimming experiment requirements.

[0100] Specifically, the experimental method:

[0101] 1) A large sample of subjects that meet the experimental requirements is used as the experimental subjects;

[0102] 2) Use automation to divide the subjects into two groups, A and B. Use a programming language such as Python's random library to write a script. Enter the subject number, the script will randomly shuffle the numbers and evenly divide them into two groups. The results will be automatically saved to a CSV file for subsequent experimental calls. Subjects in group A will first complete a set of experimental tasks with ambient light changing from low to high, and then complete another set of experimental tasks with ambient light changing from high to low. Subjects in group B will first complete a set of experimental tasks with ambient light changing from high to low, and then complete another set of experimental tasks with ambient light changing from low to high;

[0103] 3) Start the experimental system, and the experimenter explains the experimental purpose, experimental tasks and precautions to the experimental subjects;

[0104] 4) The subject logs into the dimming experiment software system under the guidance of the experimenter and fills in basic information;

[0105] 5) Experimental task practice: each subject first practices the dimming experimental task to familiarize themselves with the basic experimental task process, experimental methods and precautions;

[0106] 6) Formal experimental process:

[0107] ①After the subjects have clearly understood the experimental methods and requirements, the experiment begins;

[0108] ② The tester adjusts the brightness of the ambient light source to make the ambient light intensity reach the specified experimental value;

[0109] ③ The subject slides the 5th sub-area to adjust the display brightness, adjusting it to the minimum brightness, optimal brightness, and maximum brightness acceptable for clearly seeing the display information. After each brightness adjustment, the subject searches for and touches the corresponding object block according to the requirements of the 7th sub-area in the middle area of ​​the dimming display screen. The dimming experiment software compares the two objects. If the two are the same, the next brightness adjustment is performed. If the two are different, the previous adjustment process is repeated until the two are the same (this operation is to verify whether the subject has operated carefully and ensure that the subject can clearly identify the displayed information).

[0110] ④ The dimming experiment software automatically records the brightness value that the subject successfully adjusts each time (i.e., the object block touched by the subject in ③ above is the same as the object block required in sub-area 7);

[0111] ⑤ The experimenter continues to adjust the ambient light intensity until the illumination value on the display reaches the next experimental value (the ambient light gradually changes from dark to bright, then from bright to dark, or from bright to dark, then from dark to bright for one person).

[0112] ⑥ Replace the next subject and repeat the above experimental steps.

[0113] The dimming experiment software automatically records the ambient light illumination values ​​collected by each sensor and the display brightness values ​​adjusted by the subjects, and exports the data as an Excel file, which can be used for various experimental analyses.

[0114] The beneficial effects of the present invention are as follows:

[0115] (1) The greatest advantage of the present invention is the construction of an experimental system and experimental method composed of software and hardware. The display has a touch function; based on the experimental software, the display screen can be partitioned, and each area can present display information related to the experimental content, as well as experimental operation-related information and experimental requirements. At the same time, the information on the display interface can be defined as several object blocks through software according to the experimental requirements, and touch operations and records can be performed.

[0116] (2) The system of the present invention integrates low-light and high-light sensors, which can more sensitively detect ambient light intensity and achieve more accurate optical measurements. In addition, the experimental hardware and software are compatible and open, and can be connected and work together with a variety of devices, allowing users to modify and expand system functions or modify experimental screens according to usage requirements to meet different experimental needs. The brightness quick adjustment button and brightness fine-tuning button can achieve infinite adjustment of the display brightness, which can greatly improve the operability of the experiment and the accuracy of adjustment.

[0117] (3) The present invention also establishes an experimental method. For the changes in ambient light brightness from low to high and from high to low, the subjects are randomly divided into two groups, A and B, and the subjects complete the experiments from low to high to low and from high to low to high, respectively. The purpose is to balance the influences of the subjects such as learning effect, fatigue effect, dark adaptation and light adaptation. The subjects adjust the minimum brightness, optimal brightness and maximum brightness of the display that they can accept according to the experimental requirements. After each adjustment, it is necessary to check whether the subjects can search for the required information (that is, search and touch the corresponding object block on the display according to the requirements of the seventh sub-area module). If the touch is wrong, the experiment needs to be completed again, ensuring that the brightness adjustment of the subjects is to see the information clearly.

[0118] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
