Description

Technical Field

[0001] The present invention relates to the technical field of display devices, and in particular to a sample display device and method for studying consumer attention. Background Art

[0002] When conducting consumer attention research, consumers are usually asked to wear eye-tracking glasses and observe samples in a sample display device. The consumer's eye movement trajectory, gaze point, and pupil changes are recorded to obtain the attention of the samples.

[0003] Currently, sample display devices typically use a fixed background color (e.g., white) and a single light source (e.g., white LED light). When conducting consumer attention studies using these display devices, it's impossible to quantify the impact of different hues (HSV color wheel 0-360°) and spectral components (CCT 2700K-6500K) on visual attention. Visual attention is typically measured using eye-tracking glasses. Traditionally, sample display devices rely on manual replacement of background panels and lighting fixtures, resulting in long experimental cycles for visual attention studies, limited variable combinations, and an inability to adapt to diverse needs. Summary of the Invention

[0005] The present invention solves the above-mentioned technical problems by adopting a technical solution: a sample display device for studying consumer attention, comprising a display stand, a lighting module, a backlight screen and a control terminal; the display stand is used to place samples, the lighting module is installed above the display stand and is used to emit a light source of corresponding luminous intensity under the control of the control terminal, and the backlight screen is installed behind the display stand and is used to display a corresponding background color under the control of the control terminal.

[0006] Furthermore, the backlight screen includes an RGBW four-color LED array and an E Ink electronic ink screen, and the background color is adjusted by HSV color circle parameters and grayscale.

[0007] Furthermore, the lighting module includes a multi-spectrum light source, and the luminous intensity is changed by controlling the driving current of the LED in the multi-spectrum light source through a PID algorithm.

[0008] The present invention also provides a method for studying consumer attention, using a sample display device for studying consumer attention as described above. The method includes: controlling the combination of background color and luminous intensity through a control end, and allowing consumers to wear eye-movement glasses to observe the sample display device with samples placed thereon, obtaining eye-movement data under different combinations, analyzing the eye-movement data under different combinations, and obtaining the attention of the samples under different combinations.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a structural schematic diagram of a sample display device for studying consumer attention provided by the present invention, wherein 1 represents a sample, 2 represents a sample display device, 3 represents a display stand, 4 represents a lighting module, 5 represents a control terminal, and 6 represents a backlight screen. DETAILED DESCRIPTION

[0011] like Figure 1 As shown, the present invention addresses the problem that existing sample display devices are unable to adapt to the diverse matching needs when conducting consumer attention research. A sample display device 2 for consumer attention research is provided, comprising a display stand 3, a lighting module 4, a backlight screen 6, and a control terminal 5. The display stand is used to place samples 1. The lighting module 4 is mounted above the display stand 3 and is configured to emit a light source of corresponding luminous intensity under the control of the control terminal 5. The backlight screen 6 is mounted behind the display stand 3 and is configured to display a corresponding background color under the control of the control terminal 5. In this way, the background color and luminous intensity can be changed by the control terminal to adapt to diverse matching needs. The background color and light intensity can be changed quickly, reducing the research cycle.

[0012] Furthermore, the backlight screen includes an RGBW four-color LED array and an E Ink electronic ink screen, and the background color is adjusted using HSV color wheel parameters and grayscale. The RGBW four-color LED array can present 95% of the color range of the Rec. 2020 standard. The HSV color wheel parameter range is 0° to 360° in 1° steps, and the grayscale adjustment range is 0-100%. This allows for more than 2000 background color combinations. The E Ink electronic ink screen has a refresh rate of no less than 20Hz.

[0013] Furthermore, the lighting module includes a multi-spectral light source, and the luminous intensity is varied by controlling the driving current of the LEDs in the multi-spectral light source using a PID algorithm. The multi-spectral light source has an adjustable color temperature range of 2700K-6500K, a color rendering index (CRI) ≥ 95, supports stroboscopic mode (i.e., an adjustable range of 1 to 100 flashes per second), supports gradual transition (i.e., the transition time can be freely adjusted from 0.1 seconds to 5 seconds), and an illumination uniformity error of no more than 2%.

[0014] The present invention also provides a method for studying consumer attention, using the aforementioned sample display device for studying consumer attention. The method comprises: controlling the combination of background color and luminous intensity via a control terminal, having consumers wear eye-tracking glasses to observe the sample display device with the sample placed thereon, obtaining eye movement data for different combinations, analyzing the eye movement data for the different combinations, and determining the attention levels of the samples for the different combinations. Thus, the background color and luminous intensity combination that results in the highest attention level for the sample can be selected.

[0015] Specifically, the eye movement data under different combinations are analyzed to obtain the attention of samples under different combinations, including: aggregating discrete gaze points in the eye movement data into interest regions, taking the sample as the interest region, obtaining the gaze duration of each gaze point of the sample, and calculating the weight of each gaze point, adding the weights of each gaze point of the sample, and then normalizing them to obtain the attention of the sample.

[0016] The weight of each fixation point can be calculated as follows: a low weight, such as 0.2, is assigned to a fixation point with a fixation duration of less than 100ms, and a high weight, such as 1.0, is assigned to a fixation point with a fixation duration of more than 300ms. The weight calculation formula for the fixations with other fixation durations is: where w i represents the weight, t i represents the fixation duration of the i-th fixation point.
