Adaptation of ACTivate Your Wellbeing, a Digital Health and Well-being Program for Young Persons: Co-design Approach.

ACTivate your wellbeing is a digital health and well-being program designed to support and encourage positive lifestyle behavior change. The website includes 5 lifestyle behavior change modules and a 12-week well-being intervention based on acceptance and commitment therapy. It was timely to adapt the resource for a new audience in the wake of the COVID-19 pandemic. Young persons' mental health needs have increased substantially, and lifestyle behaviors play a critical role in both mental and physical health statuses. This study aimed to adapt an existing health and well-being website for use by young persons aged 16 to 24 years. A 3-staged participatory, co-design approach was adopted. The participants reviewed the existing program and provided feedback (stage 1) before cocreating new content (stage 2). Finally, the updated program underwent formative evaluation (stage 3). Two groups were created: one had access for 3 weeks and the other could self-select their study duration. The options were 3 weeks, 60 days, or 90 days. Outcome measures were the Warwick and Edinburgh Mental Well-being Scale, 4-item Patient Health Questionnaire, and Acceptance and Action Questionnaire version 2. Stage 1 identified that the website was appealing to the new audience (19/24, 79%), and the 3 web-based focus group discussions explored data from the written review in more depth to identify and clarify the main areas for update and adaptation. Overall, 3 themes were developed, and the data informed the creation of 6 tasks for use in 5 web-based co-design workshops. Stage 2 led to the cocreation of 36 outputs, including a new name, new content, scenarios, images, and a new user dashboard, which included streaks and an updated color scheme. After the website update program was completed, 40 participants registered to use the website for formative evaluation (stage 3). Data analysis revealed differences in engagement, completion, and mean well-being after intervention between the 2 groups. The completion rate was 68% in the 3-week duration group, and well-being scores improved after intervention. Young persons engaged actively with the participatory design process. The participants discussed the updates they desired during the web-based discussions, which worked well via Zoom (Zoom Video Communications Inc) when small groups were used. The participants easily cocreated new content during the web-based co-design workshops. The web-based format enabled a range of participants to take part, share their ideas, search for images, and design digital content creatively together. The Zoom software enabled screen sharing and collaborative whiteboard use, which helped the cocreation process. The formative evaluation suggested that younger users who engage more with the website for a shorter duration may benefit more.

Emocolor: An assistant design method for emotional color matching based on semantics and images

AbstractMuch research has been done on the relationship between emotions and colors, and many color scheme recommendation tools have been developed. These tools can often help recommend a suitable color scheme to express a certain emotion, but it is still difficult to design satisfying schemes based on such recommendations. In this study, based on the Color Scheme Bible, Compact Edition, we developed Emocolor, which allows professionals to generate a large number of color schemes based on emotional words or emotional images. It is also used to iteratively optimize the generated color schemes based on an interactive genetic algorithm to find the color scheme design that best matches the user's emotion. Through the evaluation of tram color schemes based on emotional words, Emocolor can effectively generate tram color schemes that match users’ emotions. It can also effectively transfer the emotion of an image with a single dominant color to a tram color scheme. In short, Emocolor can help professionals describe the relationship between emotion and color in a more accurate way and design emotional color schemes. Emocolor can be applied in advertising design, product design, interior design, and other fields.

Tropical Interior of Pick a Bite Startup using Sustainable Materials

Snacks are types of food that are very popular among Indonesian people today because they have practical value and are suitable for modern lifestyles. However, snacks generally contain high sugar and calories, which are not good for health. From these problems, Pick a Bite, as a startup, is offering healthy and delicious snack products served in a cake shop. This store has a tropical design concept in its interior, starting from the floor, walls, ceiling, and furniture. This research aims to create an interior design for Pick a Bite startup using sustainability materials. The method used in this research is a single case study. The colour scheme used in the interior concept departs from the colours of the company logo. At the same time, the concept of sustainable materials is contained in the selection of materials in the shop interior. The floors and furniture use a wood texture made of environmentally friendly synthetic materials. The walls use white brick wallpaper motifs to emphasize the natural elements, while the lights used on the ceiling are energy-efficient LEDs. Using sustainable materials aims to reduce the negative impact on the natural environment.

User Engagement Testing with a Pilot Decision Support Tool Aimed to Support Species Managers

Abstract Species status assessments (SSAs) are required for endangered species by the U.S. Fish and Wildlife Service and focus on the resiliency, redundancy, and representation of endangered species. SSAs must include climate information, because climate is a factor that will impact species in the future. To aid in the inclusion of climate information, a decision support system (DSS) entitled Climate Analysis and Visualization for the Assessment of Species Status (CAnVAS) was developed by the State Climate Office of North Carolina using a coproduction approach. In this study, users viewed a mock-up version of the CAnVAS interface displaying a sample layout of future projections for three key climate variables (average precipitation, average maximum temperature, and occurrence of maximum temperature) at a location of interest. This assessment of the pilot version of the CAnVAS DSS was the first step in refining CAnVAS for species-manager use. This research analyzed the differences in usability between two pilot versions of the CAnVAS DSS through eye tracking and subsequent interviews with novice users. The two pilot versions of CAnVAS differed in the way data were displayed on graphs and the color ramps used on regional maps. We found that graphically displaying temporal climate information through box-and-whisker plots and spatially through a sequential color ramp from white to purple were more effective than alternative displays at communicating climate information on endangered species. The results of this research will be used to further develop the CAnVAS DSS tool for future implementation. Significance Statement A decision support system was developed for U.S. Fish and Wildlife Service biologists to incorporate more climate information in species status assessments for endangered species. This tool was tested through eye tracking and interviews with a novice undergraduate student sample to best refine the tool for stakeholder use. This work was able to discover that graphically displaying data in box-and-whisker format and spatially displaying data with a sequential color scheme of white to purple was best for usability purposes. The authors provide these recommendations for those who are producing usable products.

A Seven-Step Technique on PowerPoint Slide Preparation for Anatomy Lectures: A Cognitive Load Theory Approach

Lecturing remains a main teaching method in anatomy education, despite being argued as ineffective in promoting understanding and higher-order cognitive skills. Designing and preparing anatomy lecture slides is a challenging task, as anatomy is a content-driven subject that involves complex threedimensional diagrams. Overly wordy, overcrowded slides and poor organisation of text and pictorial materials are among the problems related to anatomy lecture slide preparation. These unorganised and problematic slides impose a high cognitive load on students and thus hinder learning. Hence, this paper elaborates on the strategies for lecture slide preparation that were formerly mentioned by the authors in a lecturing guideline known as the cognitive load theory lecture model. The strategies were organised into seven steps: (a) step 1: select plain background slides; (b) step 2: use headings and subheadings; (c) step 3: use visual cues and signals; (d) step 4: select a proper font type and size; (e) step 5: use text treatment; (f) step 6: choose a suitable colour scheme; and (g) step 7: synchronise all sub-elements. This paper also provides tested examples for each step to facilitate comprehension of the lecture content while applying the strategies.

Designing the “NCU Information Portal” — analysis of the mockups of the website based on the elements of user experience and information architecture

The study aimed to compare three mockups (static graphic designs) of the Information Portal of the Nicolaus Copernicus University in Toruń in terms of user experience and information architecture indicators and identify the best one to use for creating an active website. The research used an eye-tracking method, usability tests, observations and surveys. Most respondents indicated that mockup no. 3 was the best of the three proposed static website page designs. The respondents justified their choice, among other things, by the fact that it was clear and easy to use, had a functional layout of information and an appropriate colour scheme. The design chosen by respondents has been improved to reflect their suggested modifications. Its final version can be viewed at https://portal.umk.pl/.

Urban landscape composition: turning a panoramic sketch into a painting

The modern landscape painter oftentimes finds himself slavishly tied to nature, its motifs. Yet, finding tailor-made exemplary landscape compositions in nature appears to be a challenge of its own. Thus, enlargement of landscape sketches to the size of a painting, a rather prevalent technique, seems to be nothing but a blind alley. The optimal solution, however, is to produce a paradigmatic natural motif sketch and convert it into a painting, by designing a proper composition and portraying the state of nature that allows, better than others, to reveal the intended artistic image. In order to create such an image, the artist must change the natural motif, adding some elements or removing others, thereby transforming the landscape ensemble into a harmonious whole.Remarkably, research rooted in the theory of landscape composition has so far largely neglected the principles and methods of composing panoramic urban landscapes. Meanwhile, a consummate arrangement of a city panorama is undoubtedly among the hardest tasks to perform. The aim of this paper, therefore, is to address the challenging endeavor in question: it describes the process of creating a large-scale landscape painting, made in multi-layer watercolor using a life sketch. Particular attention is paid, among others, to the development of the image, selection of the optimal composition and its center, adjustment of the perspective, space depth, portrayal of foreground elements, rhythm organization, choice of a suitable state of nature, as well as apt color scheme.

Understanding healthcare providers’ electronic health record (EHR) interface preferences via conjoint analysis

ObjectiveThe emergence of Electronic Health Records (EHRs) has been beneficial in processing administrative and clinical data for quality healthcare information. Despite being patient-centered, a number of these technologies have a fractional consideration of the human–computer interaction, which affects the healthcare professionals as end-users. This attempted to surface the healthcare providers’ preferences of an ideal EHR system interface in the community setting. Materials and methodUsing an orthogonal main effect design of conjoint analysis, a select group of healthcare providers (n = 300) were asked to sort choice cards, which contains five (5) attributes of EHR interface with specific level. Data were analyzed using Sawtooth v.18 and SPSS v.21. ResultsHigh importance was given to color scheme and device platform. Further, the part-worth analysis revealed the preference for an EHR with the following attributes: (a) smartphone device, (b) triadic color, (c) minimalist design, (d) chunked layout and (e) icon-centered menu. DiscussionVisual interest and technology needs of the community healthcare providers shaped their preferences. These provide substantial perspectives on how to improve usability of EHR interface systems. ConclusionFindings underscored the expanded roles of the healthcare professionals in the successful development of EHR systems.

Effects and interactions of labels’ color scheme and the individual difference variable lay rationalism on pro-environmental choices

Recent eco-labeling research suggests that labels that use traffic light colors to communicate an evaluation of product attributes are more effective in guiding consumer choices toward environmentally friendlier products than those that merely provide quantitative information. However, it remains unclear whether the effect of traffic light labels is attributable to the additional information provided by the colors or whether the colors themselves impact consumer choices. We investigated the influence of labels' color scheme on consumers' preferences for environmentally friendly electricity. In two experiments, participants chose between electricity products differing in price and carbon emissions. The products had labels based on either traffic light colors, grayscale colors, or text (Study 2) to classify carbon emissions as low, medium, or high. Furthermore, we used the lay rationalism scale to assess participants' tendency to base decisions on feelings versus reason. The two main findings were that traffic light labels increased the choice share of low-emission electricity relative to text-based labels but not relative to grayscale labels, and that there is an interaction effect between labeling format and lay rationalism. Another finding is that both emotional affinity toward nature and guilt proneness are strong predictors of preference for low-emission electricity. Our data underline the importance of examining different label formats and further suggest that labels should be designed according to a target group's decision-making style.

Communicating about the social determinants of health: development of a local brand

ABSTRACT Background Successful comprehensive population-based approaches to chronic disease prevention leverage mass media to amplify messages and support a culture of health. We report on a community-engaged formative evaluation to segment audiences and identify major themes to guide campaign message development for a transformative health communication campaign. Methods Four key phases of campaign development: (I) Formative evaluation to identify priorities, guiding themes, and audience segments (interviews/focus groups with residents, N = 85; representatives of community-based partner organizations, N = 10); (II) Brand development (focus groups and closed-ended surveys; N = 56); (III) Message testing approaches to verbal and visual appeals (N = 50 resident intercept interviews); (IV) Workshop (N = 26 participants representing 15 organizations). Results Residents were engaged throughout campaign development and the resulting campaign materials, including the campaign name and visual aesthetic (logo, color schemes, overall look and feel) reflect the diversity of the community and were accepted and valued by diverse groups in the community. Campaign materials featuring photos of county residents were created in English, Spanish, and Hmong. Plain language messages on social determinants of health resonate with residents. The county was described as a sort of idyllic environment burdened by inequality and structural challenges. Residents demonstrated enthusiasm for the campaign and provided specific suggestions for content (education about disease risks, prevention, management; information about accessing resources; testimonials from similar people) and tone. Conclusions Communication to support a policy, systems, and environmental change approach to chronic disease prevention must carefully match messages with appropriate audiences. We discuss challenges in such messaging and effectiveness across multiple, diverse audiences.

THE COLORS OF RENAISSANCE ARCHITECTURE IN SILESIA FROM THE 16TH TO THE MID-17TH CENTURY ON THE BASIS OF SELECTED EXAMPLES

The article is the first attempt to summarize the issue of color in the Renaissance architecture of Silesia. The introduction outlines the purpose of the article; the architectural context of princely residences, noble and patrician houses, and public utility buildings; and also, the timescale of the Renaissance in Silesia. The basis for examining color schemes was the conducted architectural research, in which, in many cases, the authors participated personally. They included the analysis of technology, building materials, and architectural details, as well as stratigraphic studies of plasterwork and paint layers. As a result of the carried-out analysis, two basic colorschemes were specified. One involves contrasting smoothly painted plaster with brightly painted architectural details, and the other consists in covering the entire surface of walls with a network of thin stripes that imitate squares. Both color schemes were present in two different versions - with the use of either two or three colors, with the most common being: white, red, ocher, black and gray.

The visual design of urban multimedia portals.

In the visual design of a portal website, color is the first intuitive factor for users. It is relatively difficult for the designer of a city portal website to choose a color system that represents a city's unique color from among the many available options. Therefore, this study extracted a decision-making model of the urban color system, which can help decision-makers and designers choose among color systems, and then effectively design a portal website that conforms to local cultural attributes. The proposed method to solve the problem involved obtaining optimal color matching by performing weight analysis of colors through 123 sample color semantics, factor analysis, and a fuzzy analytic hierarchy process. Semantic analysis was used to classify colors into four categories of fashion, technology, calm, and dazzling. The fashion color matching scheme scored relatively high. Web page color matching schemes with a white background were popular, among which a white and green color matching scheme scored relatively high. At the same time, there are differences in color preferences between genders and cultures. This study is significant because it proposes a color decision model for portal websites, which provides a reference value that can also be applied to the selection of color schemes for other types of web pages in the future.

Robotic painting: mimicking human applicators

Robotically assisted painting is widely used for spray and dip applications. However, use of robots for coating substrates using a roller applicator has not been systematically investigated. We showed for the first time, a generic robot arm-supported approach to painting engineering substrates using a roller with a constant force at an accurate joint step, while retaining compliance and thus safety. We optimized the robot design such that it is able to coat the substrate using a roller with a performance equivalent to that of a human applicator. To achieve this, we optimized the force, frequency of adjustment, and position control parameters of robotic design. A framework for autonomous coating is available at https://github.com/duyayun/Vision-and-force-control-automonous-painting-with-rollers; users are only required to provide the boundary coordinates of surfaces to be coated. We found that robotically- and human-painted panels showed similar trends in dry film thickness, coating hardness, flexibility, impact resistance, and microscopic properties. Color profile analysis of the coated panels showed non-significant difference in color scheme and is acceptable for architectural paints. Overall, this work shows the potential of robot-assisted coating strategy using roller applicator. This could be a viable option for hazardous area coating, high-altitude architectural paints, germs sanitization, and accelerated household applications.

Color and Light: A Hellenistic Terracotta Figurine of a Maenad from Myrina

During the Hellenistic period and under the growing influence of the art of painting, the polychromy of Greek terracotta figurines focused not only on an elaborate rendering of color, but also on the interplay of light and shadow. Some of the best-preserved examples clearly show the subtlety of such pictorial effects. Among them is a statuette of a standing Maenad, held in the collections of the National Archaeological Museum in Athens (inv. 5000). Dating back to 150–100 BCE, it is a high-quality testament to the sculptural, as well as pictorial, coroplastic production in the workshops of Myrina (Eolide, Turkey). Combining multi-scale examination, multi-spectral imaging and non-invasive spectroscopic investigations (XRF, FTIR, FORS), a scientific study of the artefact was carried out within the framework of the Pilina project, a collaborative research program between the Louvre, the C2RMF, the National Archaeological Museum and the French School in Athens. This article presents the main results of the study by discussing the color scheme, identification of some pigments and colorants (clays of the kaolinite group, ochres, cinnabar, Egyptian blue, an anthraquinone of plant origin, likely madder, gold leaf), and painting techniques aiming at achieving chiaroscuro effects.

Computer vision-based prototype robotic picking cum grading system for fruits

Huge harvest and post-harvest losses in conventional processes and methods demands precise applications of agricultural inputs. Computer vision based robotic picking is one of such systems that reduces time consumption, labor requirement; and enhances fruits picking and grading efficiency. In this study, an all-in-one prototype robotic picking cum grading system is developed that integrates robotic picking and fruit quality recognition based grading processes. Therein, computer vision algorithms are used for fruit detection followed by picking and placing through controlled robotic arm. For fruit detection, the steps includes color scheme conversion, masking of normal/fresh skin, masking of defects, and morpological dilation operations; and opencv library is used for implementation in Python Language on Anaconda Spyder Integrated Development Environment (IDE). The detection information is then communicated to robotic arm through microcontroller. The fabricated arm is of 4 Degrees of Freedom (4-DOF) and therein, four servo motors aid the robotic arm. The time taken by proposed computer vision algotihms scheme is as follows: 0.0035136 s, 0.0081954 s, 0.0005433 s, and 0.0002408 s for color scheme conversion, segmentation, morphological operations, and bitwise operations respectively; and total time for complete scheme is 0.0125 s. Overall, the developed system took average time of 15 s for one grading cycle in case of poor quality fruits. For this case, no action is carried out and the fruit passes the conveyor directly to storage bin. However, the time required for good quality fruits is high i.e. 21 s as the robotic arm picks and places the fruits for this case.

Integral Risk Assessment in Steel Ropes Diagnostics Using Computer Vision

Introduction. Currently, the technical condition of ropes of cable-working machines is evaluated periodically according to regulatory documentation. At the same time, methods of visual and instrumental control are used, which depend on the skills and physical capabilities (vision) of the personnel performing the work. There is no unified system of continuous assessment of the technical condition based on a set of factors that does not depend on the human factor. As a result, emergencies occur even when all routine maintenance is carried out on time. To correct this situation, it is proposed to use a computer vision system and neural networks, which allows determining its suitability for further operation by risk levels based on the totality of detected and identified defects, with the interpretation of their results in the color scheme: green — acceptable, yellow — increased, red — high. The work objective is to propose an integral method for risk assessment of operating machines with rope traction when defects and their combinations are detected in a steel rope using computer vision while excluding the influence of the human factor. Materials and Methods. Training of the neural network was carried out on the basis of statistical data of defects obtained from the results of technical inspections of machines with rope traction, on sections of the rope, multiples of its six and thirty nominal diameters according to GOST 33 718. Indexing of risks in the color scheme was carried out according to GOST 55 234.3 to develop a strategy for steel ropes maintenance. A certificate of registration of a computer program was obtained for the neural network program code. The neural network processes visual and measurement control data based on computer vision. Results. An integrated risk assessment system has been created for the diagnosis of steel ropes using computer vision, which allows you to detect defects in steel ropes timely, assess the existing risk of further operation and give recommendations to specialists of operating organizations in real time. This will dramatically reduce the risk of accidents, injury and death of people at facilities using steel ropes. Discussion and Conclusion. The proposed integrated risk assessment system can be applied in any facility that uses rope traction. These are elevators for various purposes, funiculars, cable cars, cranes and many other machines. It should be noted that the estimated commercial cost of the system is low; therefore, the system is available to a wide range of consumers.

Bringing Happiness into Family Circles in McDonald’s Advertisements

This study was conducted to analyze verbal and visual expressions used in McDonald’s video advertisements. In the video advertisement, the writer focuses on how family circles create the idea of happiness through verbal and visual expressions. The writer observed using the multimodality theory by Paltridge (2012) and Gee (2004). The writer used the qualitative content approach in this study. The finding of this study shows that “Togetherness” is the main key to creating the idea of happiness in family circles from McDonald’s advertisements. More studies involving other themes and semiotic elements are recommended for further study. The result of this study will show how verbal expressions will reveal the idea of happines by stating all the keywords. At the same time, visual expressions will reveal how the idea of happiness can be seen with the help of some elements like colour scheme, clothes, place, expressions, and gestures.

Analysis and Visualization of Vessels’ RElative MOtion (REMO)

This research is a pilot study to develop a maritime traffic control system that supports the decision-making process of control officers, and to evaluate the usability of a prototype tool developed in this study. The study analyzed the movements of multiple vessels through automatic identification system (AIS) data using one of the existing methodologies in GIScience, the RElative MOtion (REMO) approach. The REMO approach in this study measured the relative speed, delta-speed, and the azimuth of each vessel per time unit. The study visualized the results on electronic navigational charts in the prototype tool developed, V-REMO. In addition, the study conducted a user evaluation to assess the user interface (UI) of V-REMO and to future enhance the usability. The general usability of V-REMO, the data visualization, and the readability of information in the UI were tested through in-depth interviews. The results of the user evaluation showed that the users needed changes in the size, position, colors, and transparency of the trajectory symbols in the digital chartmap view of V-REMO for better readability and easier manipulation. The users also indicated a need for multiple color schemes for the spatial data and more landmark information about the study area in the chartmap view.
