Technical Field

The invention belongs to the technical field of human body clothing design, and particularly relates to a somatosensory technical method based on visual perception of an eye tracker.

Background

Vision is the most important information source in human sense, and color as visual stimulus has influence on human emotion change and a series of physiological processes of human body. Garments, particularly outdoor garments, are required to meet both the functional needs of outdoor sportsmen and the fashionable needs of diverse and personalized consumers. Thus, color is an important component of apparel, and is an important aspect of apparel design that is not negligible.

At present, most clothes researches aim at the test of the clothes performance and the development of novel fabrics, but the research on behavior preference based on perceptual requirements is less, only the research on color is only limited on subjective question answering, namely, a manufacturer obtains the color requirements of a consumer on clothes or certain clothes in a questionnaire mode, the color requirement expression mode of the research mode is singly based on the oral expression of the consumer, and in many times, the requirements expressed by the oral expression of the consumer are not the real requirements, and under the normal condition, the behavior expression of the consumer can more truly reflect the real requirements of the consumer compared with the oral expression. Therefore, the mode of behavior mode capture is convenient for the business to research the clothing color.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 4, the present embodiment discloses a somatosensory technical method based on visual perception of an eye tracker, which includes the following steps:

s1, dividing a plurality of interest areas for a plurality of colors of various clothes, and tracking eye movement data of a testee in the interest areas through an eye tracking system;

specifically, the present embodiment takes four items of clothing, namely, the jacket, the fleece sweater, the down jacket, and the sports T-shirt, as sample clothing, that is, the plurality of items of clothing in step S1 includes the aforementioned four items of clothing. Meanwhile, the multiple colors of each garment comprise a neutral color, a cold color system and a warm color system, and the neutral color, the cold color system and the warm color system respectively comprise at least three colors. In order to ensure the reliability of the experiment, the colors of the clothes are the same among different clothes, and the number of the colors is the same among different color systems. In particular, the center color, the cold color system and the warm color system of the jacket of the embodiment have six colors, and similarly, the center color, the cold color system and the warm color system of the down-catching sweater, the down jacket and the sports T-shirt have six colors which are the same as those of the jacket.

Specifically, the interest areas of four types of clothes are divided, fig. 2 shows the neutral color of the jacket as an example, a solid line rectangular frame in fig. 2 is the divided interest areas and is used for researching the attention situation of each color area of the neutral color of the jacket, fig. 3 shows the jacket as an example, the solid line rectangular frame is still the divided interest areas, and the interest areas of the neutral color, the cold color system and the warm color system are sequentially arranged from left to right and are used for researching the attention degree contrast situation of the cold color system, the neutral color system and the warm color system of the jacket.

S2, analyzing eye movement indexes including a fixation point moving track, fixation time and interest area retention time according to the eye movement data;

and S3, marking the interest areas with different colors according to the watching frequency degree according to the analysis result so as to obtain a contrast heat map for comparing the attention degrees of various colors of various clothes.

Since the eye movement data may be lost, such as nystagmus amplitude is large, blinking is too frequent, visual field is lost or shifted, and the like, that is, the gaze point of the subject exceeds the maximum capture range of the eye tracker, this embodiment further includes, before step S2:

the eye movement data is checked for integrity and invalid samples with missing values and severely lost field of view are rejected.

Specifically, in step S1, the eye tracking system is an eye tracker-based desktop eye tracking system or a mobile eye tracking system. In particular, the eye tracking system herein adopts a desktop type eye tracking system of EyeLink1000, and DV analysis software for recording and analyzing any one or more eye movement indexes of a gaze point movement track, a gaze time and a region of interest dwell time is embedded in the eye tracking system.

Further, in step S2, the method specifically includes:

s21, obtaining eye movement indexes including a fixation point moving track, fixation time and interest area retention time;

and S22, making a dynamic view, a spatial superposition view and a time sequence heat map for a plurality of interest areas according to the eye movement indexes.

And in step S3, the gaze points are colored in the spatially superimposed view according to the dynamic view and the gaze points located at the different attention areas are colored in different colors according to the time-series heat map to obtain a contrast heat map as shown in fig. 4.

Preferably, the areas with higher fixation frequency are colored more deeply, and conversely, the areas with lighter fixation points are colored more intensively, i.e. the areas with more fixation points are focused more, and accordingly, the fixation points at the positions are colored more deeply. Areas of frequent fixation may be designated in red and areas of lesser fixation in green.

A comparative heat map, as shown in fig. 4, from left to right, top to bottom, with neutral colors comprising dark blue, wine red, brownish red, gray, black and white, cold color system comprising grass green, cyan green, dark green, sky blue, blue violet and purple, and warm color system comprising dark red, brilliant red, bright yellow, pink and yellow. Through the comparison heatmap, all colors of 3 color systems of the four-style clothes are concerned by the testee, and the attention degrees of different styles of the same color system are different. Taking the neutral color as an example, the wine red money of the jacket and the fleece sweater is concerned more, the black, white and gray money of the down jacket and the sports T-shirt is concerned more, and the focus of the attention is mainly on the collar and the chest.

The embodiment adopts mathematical statistics and shows eye movement capture results in a mode of comparing heat maps, quantitatively analyzes and visually displays the fixation difference from styles to colors, so that the color somatosensory support theory can provide theoretical support for the field of garment engineering technical garment design and research and development, and assists in optimizing the layout and the color vision perception scheme.
