Application of artificial bee colony algorithm and back propagation neural network in color evaluation of human–machine interaction interfaces

AbstractPeople prefer an attractive human–machine interaction interface, and color is an important factor affecting attractiveness. Therefore, to evaluate the color of human–machine interaction interfaces, a back propagation neural network (BPNN) optimized by the artificial bee colony (ABC) algorithm was proposed to predict and evaluate the interface color. The process of determining the weights and thresholds of each layer of BPNN was transformed into the process of searching for the best honey source. Based on a comprehensive analysis of visual aesthetics and usability, the five color evaluation characteristics of human–machine interaction interfaces (color type, color harmony, color area, color distribution, and color difference) were extracted and expressed mathematically. The color evaluation model of the human–machine interaction interface was constructed by considering the color evaluation characteristic values as the input of BPNN and the mean values of aesthetic degree and usability by subjective evaluation as the output. The color evaluation data of websites and iPhone apps were used to train and validate the model. In Study 1, the mean squared error (MSE) and R‐Square of ABC‐BPNN were 0.0399 and 0.9400, respectively. In Study 2, the MSE and R‐Square of ABC‐BPNN were 0.0285 and 0.9195, respectively. The results showed that the prediction effect of the ABC‐BPNN model was more accurate than that of the standard BPNN and Elman‐NN models. Finally, the proposed method was applied to the interface color design of an app to improve young people's sleep, producing a color scheme that fulfilled the user's psychological expectations, which accelerated the design process.

Exploration on the Application of Color Contrast and Harmony in Advertising Design

This paper briefly summarizes the principle of color contrast and color harmony, which mainly explains their applications in advertising design. From the exploration, it is found that the moderate contrast, sharp contrast and progressive contrast of color are often employed in advertising design, furthermore, the identity harmony, approximate harmony and order harmony is also widely used in advertising design. Therefore, in order to better carry out the application of color contrast and harmony, the advertising design department should actively train professionals in color, strengthen advertising design review and conduct the all-around market research.

Joyful Colors in Krishna Prakash Shah's Abstract Artworks

Aesthetic pleasure and joy are the dominant features of Krishna Prakash Shah's colorful compositions. Shah, one of the renowned contemporary Nepali abstract artists, presents art forms without referential and recognizable contents. In other words, the form itself is its content. The works have the power to arouse rapture and relish through harmonious colors although the viewers may not able to find fixed significance. Coherent colors, rhythmic waves, playful shapes and organic composition in his paintings contribute to create beauty and provide aesthetic pleasure to the viewers. This research paper analyzes Shah's abstract paintings from the perspective of aestheticism and traces joyful colors and rhythmic waves in his works. The study uses qualitative methods of research since there can be multiple interpretations of the same artwork, and the subjectivity of the critic has a significant role to derive the thesis statement.

Quantitative study on landscape colors of plant communities in urban parks based on natural color system and M‐S theory in Nanjing, China

AbstractPlant color landscape plays an important role in improving the quality of visual landscapes, regulating the emotion of landscape space, and highlighting the characteristics of urban landscapes. How to reasonably quantify and create rich plant color landscapes to achieve the best visual perception of the plant color landscape at different visual scales, so as to better meet the aesthetic needs of the public, has become a hot and difficult issue in the plant color design and application. Therefore, this article selects four typical urban parks in Nanjing to study the color characteristics of plant communities. The natural color system color card is used to extract plant color data. The color harmony and suitability degree of the plant community and external environment are quantitatively evaluated according to the Moon‐Spencer (M‐S) color harmony theory. The correlation between the chromaticity difference, color harmony, and color suitability of the plant landscape color is strong, whereas that between the chromaticity difference and lightness difference of the plant landscape color is weak. Among the four urban parks, the color harmony is the highest, and the appropriate color is the lowest in Xuanwu Lake Park. In addition, among the 12 selected plant community landscapes, the plant community number A3 in Xuanwu Lake Park has the highest color harmony and D3 in Gulin Park has the lowest color harmony. In short, the quantitative study of the plant community landscape color can provide new ideas for improving the optimal allocation of the plant community landscape color in urban parks.

A learning-based approach to automatically evaluate the quality of sequential color schemes for maps

ABSTRACT Color quality evaluation is key to judging map quality, which can improve data visualization and communication. However, most existing methods for evaluating map colors are tedious and subjective manual methods. In this paper, we study sequential color schemes, a widely used map color type and propose a learning-based approach for evaluating the color quality. The approach consists of two steps. First, we extract and characterize the cartographic factors for determining the quality of sequential color schemes, such as color order, color match, color harmony, color discrimination and color uniformity. Second, we present a model to predict the color quality based on AdaBoost, a type of ensemble learning algorithm with excellent classification performance and use these factors as input data. We conduct a case study based on 781 samples and train the AdaBoost-based model to predict the quality of sequential color schemes. To evaluate the model’s performance, we calculated the area under the receiver operating characteristic (ROC) curve (AUC). The AUC values are 0.983 and 0.977 on the training data and testing data, respectively. These results indicate that the proposed approach can be used to automatically evaluate the quality of sequential color schemes for maps, which helps mapmakers select good colors.

Perception, Preference, and Prices in Josef Albers’ Square Series

Abstract Josef Albers’ Homage to the Square series comprises a vast ensemble of compositions based on similar arrays of nested squares. The main difference among these paintings is the colors employed. Therefore, they constitute an almost natural experiment to explore color preferences. We focus on the relationship between the prices paid in public auctions for these paintings and their color attributes over a fourteen-year period. We describe the attributes of the color palette using several color-related metrics aimed at capturing dominant colors, color diversity and contrast, color harmony, and color emotions. We find that color-related metrics explain a great deal of the price variation in Albers’ Squares series. Intriguingly, dominant colors and emotions are the key variables, while color harmony, contrast and diversity play no role at all. We also find that the market favors lighter tones and bluer hues. Additionally, the analyses reveal that Albers, judged by the prices commanded by his paintings, was a quintessential experimentalist ‒ as opposed to a conceptual artist. That is, an artist who kept improving as he gained more experience playing with the same concept over and over. It is worth noting that using market prices to study color preferences or judge aesthetic merits can provide different insights regarding color preferences and color perception, given the fact that most color preference studies are carried out in experimental or artificial settings, where the subjects do not have any direct interests at stake.

Grid-based Genetic Operators for Graphical Layout Generation

Graphical user interfaces (GUIs) have gained primacy among the means of interacting with computing systems, thanks to the way they leverage human perceptual and motor capabilities. However, the design of GUIs has mostly been a manual activity. To design a GUI, the designer must select its visual, spatial, textual, and interaction properties such that the combination strikes a balance among the relevant human factors. While emerging computational-design techniques have addressed some problems related to grid layouts, no general approach has been proposed that can also produce good and complete results covering color-related decisions and other nonlinear design objectives. Evolutionary algorithms are promising and demonstrate good handling of similar problems in other conditions, genetic operators, depending on how they are designed. But even these approaches struggle with elements' overlap and hence produce too many infeasible candidate solutions. This paper presents a new approach based on grid-based genetic operators demonstrated in a non-dominated sorting genetic algorithm (NSGA-III) setting. The operators use grid lines for element positions in a novel manner to satisfy overlap-related constraints and intrinsically improve the alignment of elements. This approach can be used for crossovers and mutations. Its core benefit is that all the solutions generated satisfy the no-overlap requirement and represent well-formed layouts. The new operators permit using genetic algorithms for increasingly realistic task instances, responding to more design objectives than could be considered before. Specifically, we address grid quality, alignment, selection time, clutter minimization, saliency control, color harmony, and grouping of elements.

Optimization of Harmonious Coloring Problem in Mesh Derived Architecture

Labelling of graphs has been the allocation of integers to the nodes or edges, or perhaps both, liable to revision. Graph coloring is indeed a specialized version of graph labelling, which is an allocation of labels consists of assessment to as colors to graph that are subject to several limitations. From its simplified sense it is indeed a method to color the nodes of a graph. This article deals with the harmonious coloring of central graph of some Mesh derived Architectures. A coloring is a harmonious coloring if it is a proper coloring with the intension of a couple of colors emerges towards one edge at the most.

Objective: to identify the component features of artistic abilities of children in older preschool children. Methods: the complex of diagnostic procedures included a set of tasks developed by T. S. Komarova, N. P. Sakulina and focused on the assessment of each of the structural components of the artistic abilities of older preschool children (the ability to create an image (perception, manual skill), the ability to create an artistic image by design) allowed us to analyze the features of artistic abilities and outline the prospect of its further development, in terms of testing pedagogical conditions. Results: of the study revealed that most children of older preschool age are assigned to the low level of artistic abilities: there is a significant distortion of shape, proportion and color; the layout on the plot sheet is often broken, the compositional intent is absent, the image is static, the proportions of objects are not violated, color harmony is not expressed, 1-2 colors are used. They have difficulties in creating and implementing an artistic idea and its independent implementation, selecting means of artistic expression, a low degree of originality of the idea, and dissatisfaction with the. Scientific novelty: the dynamics and conditions for the development of the artistic abilities of modern preschool children are identified and characterized. Practical significance: methodological approaches to the development of visual abilities of older preschoolers in a preschool educational institution are presented.

Choosing Appropriate Technique for Nasal Reconstruction in Challenging Cases of Panfacial Burn: Treatment Algorithm.

The nose is one of the most challenging facial parts to reconstruct. Its asymmetries, defects, or disharmonies are easily noticeable. The complex contours, highlights, shadows, and special shape of its subunits make nasal reconstruction more difficult in panfacial burn than that of nonburned ones. This retrospective study was conducted at Zare Hospital. Twenty-five panfacial burn cases with nasal defects were studied from 2010 to 2019. Profile photos were manipulated by Adobe Photoshop. Based on the difference between the burn-related shortened nasal length and the expected photoshopped one, the severity of the short nose was detected, and the strategy of the surgery was determined. Of the 25 cases, 10 cases with normal nasal length and projection, or mild short nose with minimal alar rim, tip and/or columellar defect underwent nasal reconstruction with skin and/or composite graft. Nine patients with normal nasal length or mild to moderate short nose but moderate to severe alar defect underwent reconstruction with turndown flap plus skin and/or composite graft. Pre-expanded forehead flap (n = 1) and delayed scarred or skin grafted forehead flap (n = 5) were used for six patients with severe short nose defect. There are several procedural alternatives for the reconstruction of burn-related mild to moderate nasal deformity. For severe and deep panfacial burn, delayed forehead flap seems safe with acceptable color and texture harmony. Our designed algorithm could potentially improve the selection of proper nasal reconstruction techniques and assist novice surgeons.

Road Traffic Light in New Configuration

The three-color system containing signals of the same circular shape has been in existence for over a hundred years. Each traffic signal has been justifiably selected to have a special color light to correspond to human psychoemotional reaction (red – stop, yellow – caution, green – go) to a given color signal (British Standards, 2015) and to comply with the laws of physics (The Motivated Engineer, 2015) – Rayleigh’s scattering law (Banc SpaceTek, 2017). The main downsides of the traditional road traffic light include the following: • The uniform circular shape of light signals results in uncertainty and difficulties for road users with color blindness and visual impairments, resulting in the need for restrictions or bans on driving license issuance in some countries. This uncertainty becomes particularly acute in conditions of low visibility. • According to the concept of harmony of form and color (Itten, 1961), a green light alone corresponds to the circular (spherical-like) shape of the signal. Red and amber lights harmoniously combine with other geometrical shapes. • The uniform shape of light signals prevents the implementation of the original compact combined model of traffic lights. For example, during the day, colorblind people can tell which signal is which because there is a standard position assigned: top – bottom or right – left (Oliveira, Souza, Junior, Sales & Ferraz, 2015). This becomes problematic if the compact combined models of traffic lights are used. Engineers and inventors have been trying to solve these problems by introducing random changes in the light signal shape and complicating the traffic light design. For a long time there have been different proposals about how to eliminate the demerits of the existing traffic lights: from arbitrary changes in the signal shape (Patterson, 1988) to transformation of traffic lights into a single-section display panel (Kulichenko, 2011) which replaces among others stationary road signs. However, technical solutions like these deprive the traffic light of its signal uniformity and conciseness (simplicity, clarity and precision of its controlling effect), features which help safe traffic regulation in a busy and dynamic mode. Technical modernization of individual signal components has been going hand in hand with technological developments as light sources, diffusers, lenses, controllers, materials, control systems, timers, etc. are improved. However, adequate design and aesthetic proposals are considerably behind. The aim of this paper is to propose a concept of creating control signals of traffic light that harmonize color and form, and, as a result, to create a new model of traffic light that will be convenient for all road users.
