Adaptive seating orthosis (ASO) for Cerebral Palsy (CP) patients in Malaysia mostly are imported, highly expensive for the bottom millions, bulky and complicated design structure, and not accommodating users’ preferences. Through a study involving 10 CP patients with their parents/guardians in Ma-laysia, the goal of this paper is to re-assess the design needs of CP’s orthotic in ASO design. The purpose of the study is to identify the difficulties, as well as the ergonomic and functional problems, in caring for CP patients with the current ASO. The result of the study revealed several of the problems that parents/guardians face while taking care of the CP patient, mainly caused by technical flaws in the current ASO design. Therefore, a few design criteria have been proposed to solve the addressed problems. The contribution of this study will help as a preference for the improvement and development of ASO design.

It is known that gloss has a significant impact on colour measurement. The UV varnish used for surface finishing, spot effects, as well as special effects, such as 3D effects and formation of Braille, has a pronounced gloss effect. In this work, a comparison of the spectrophotometer measurement geometry influence on the colour measurement of an unprinted PVC sample covered with UV varnish was done. UV varnish was applied successively in layers, and patches with different number of varnish layers, from 1 to 12, were formed. Two spectrophotometers with different measurement geometries were used for the measurement: Konica Minolta CM-2600d with d/8 measurement geometry, with spectral reflection included and excluded, and different measurement aperture 3 and 8 mm, and X-Rite eXact with 45/0 measurement geometry. By comparing the measurements, it was estab-lished that there is a significant difference in the measured values between different measuring device geometries on the given samples, and that the number of UV varnish layers has a significant influence on this differenc

Special effects on a printed product can increase consumer’s interest in a product and therefore lead to higher revenues in consumer industries. For that purpose, graphic industry introduced various technologies and materials that would have such an effect and enhance consumer-goods interaction. One of those solutions is thermochromic printing. Although bringing added value, thermochromic inks have some challenges in application due to their higher sensitivity, especially when exposed to UV light. Therefore, the goal of this work is to determine whether amount of the UV radiation during curing of UV thermochromic prints, as well as exposure after printing would degrade the thermochromic print on various substrates. UV thermochromic prints were made on three different paper printing substrates using the screen printing method and dried in a laboratory controlled unit. Synthetic paper, recycled paper containing 100 % recycled cellulose fibers and bulky voluminous paper were used as printing substrates. During the UV curing of the ink, no photooxidation of the prints occurred. Additional exposure of the prints to UV radiation (after the ink has hardened) leads to their photooxidative degradation, i.e., a change in the initial color. The obtained colour difference (ΔE) is increasing with the increase of the irradiation amount. The highest colour difference is on the synthetic paper while prints on two other substrates are more resistant to UV light. A print on synthetic paper photooxidizes the fastest due to the presence of most carbonyl groups in it. Generated free radicals promote the instability of prints on synthetic paper. Research has proven that when using synthetic paper or substrates with similar characteristics, care should be taken to accurately determine the amount of UV energy required for curing in order to prevent photodegradation of the ink. The results also show that to explain any degradation of prints, the chemical components of the paper needs to be taken into account, which is rarely done.

The purpose of this research was to focus on the design of packaging openers for consumer access to the contents. The packaging opener was created to make opening easier and safer. In this study, online questionnaires were used to investigate the problems and solutions of user experiences when opening packaging. According to the findings, a major issue among the responding participants is that they should have a strong hand force. However, the hand force not only had enough energy to open the packaging, but it was also unable to open the closure at the specified location. When participants encountered opening problems, they preferred to use an assistant tool rather than ask for assistance. The risk of packaging materials, scissors, knives, and wrist and finger twisting occurred during opening packaging. According to the respondents' experiences, the four functions of the packaging opener were integrated together for the corrugated box, ring-pull a can, lug cap closure, and flexible packaging. As a result, the newly designed packaging opener required less opening force, a safer hold, and optimized hand ergonomics. The attractive configuration and comfortable grip were also important factors to consider when designing the packaging openers in this study. Opener prototypes were modelled using SolidWorks and were formed by a 3D printer. The FSUDE system was employed to evaluate the functions, safety, usability, design, and engineering of all prototypes. Based on the results of this study, form, dimension, surface, friction, and grip posture were factors affecting torque force exertion, slitting and cutting force, and openability of consumers.

This research aimed to study and analyse the interaction between humans and a tsunami disaster simulation. Besides, it aimed to develop a virtual reality (VR) adventure game in regard to preparing for a tsunami disaster caused by an earthquake. It also assessed the effectiveness of virtual reality (VR) through three perceptions, namely visual perception, auditory perception, and kinesthetic perception with the connection between the human user and the Oculus quest 1 (VR glasses) to create virtual reality that was easy to understand and reflected interesting storytelling accompanied by beautiful patterns. The research objectives were 1) to study, collect, and analyse data related to the concept of creating virtual reality (VR), 2) to design and create virtual reality (VR) adventure game, and 3) to test and assess the perceptions of virtual reality (VR) to prepare for a tsunami disaster caused by an earthquake. The results of studies and analysis based on the learning style theory and participants’ behaviour showed that the behaviour was often instilled from experiences that they had gained. This created clarity in the role of the participants and helped them learn and practice using virtual reality technology in training and deal with tsunami disasters caused by earthquakes. The results of the perception assessment of the virtual reality (VR) prototype, overall, indicated that the adventure game in a virtual reality (VR) setting to prepare for a tsunami disaster caused by an earthquake was feasible for use.

The presented article shows the results of the analysis of the factors influence on the flexographic printing process with solvent based inks. The main factors influencing the printing process quality are identified, a semantic network of influence and dependencies of these factors is constructed. The priority of factors, taking into account their influences and dependencies, is established by the ranking method. Using the Pareto rule and the construction of the corresponding diagram, four main factors are identified, the influence of which provides 70 % of the studied process quality. It is established that the most priority factors are the parameters of the printing plate, the rheological parameters of the ink, the lineature of the anilox roller and the surface properties of the material to be printed, with the following calculated values: 150, 120, 105 and 90 units, respectively. The selected factors are used to analyse their impact on the flexographic printing process by means of fuzzy logic. Accordingly, a universal set, corresponding terms and a fuzzy knowledge base with the condition "If-Then" are established for these factors in the form of linguistic variables. The formed knowledge base is tested with the help of the Fuzzy Logic Toolbox package of the Matlab technological computing environment and the corresponding prognostic models of the influence of the selected factors on the printing process quality are constructed.

Typefaces designed for the purpose of directional informative sign boards (DISB) communicate legible information related to drivers and passengers to navigate within road systems to: maintain road discipline and assist drivers to make instant decisions within a short period while operating a vehicle. The legibility of these typefaces works as a fundamental requirement. The reader's preference test (RPT) highlights that a typeface is unique due to its visual features–the anatomy of a typeface and it influences legibility performance, comprehension, memorability, priming, persuasion, perceptual fluency, and practical usage. This visual perception and the neurotic process of connecting human vision and brain is the intellectual cognition between; reader and information that acutely affects the reader to process information. When considering the amount of research work towards the advancement of DISB and typefaces designed for this purpose is at large within the western context, and more evident in Latin script but lacks in scripts such as Sinhala and Tamil within the Eastern regions. To fill this knowledge gap, the research contributes to Sinhala script discussed within the domain of typography research and proposes a draft typeface for Sri Lankan DISB. Considering legibility to be a required key factor in typefaces designed for the purpose of DISB the research methodology was structured into three stages. The first stage reviews legibility test methods, its measurements, testable factors usability and identifies the most relevant test to analyse typeface features. This section concludes by identifying RPT as the most relevant test with two variables: typeface personality traits and anatomy. Second stage adopts the two variables and tests six Sinhala typefaces that contain personality traits required for DISBs. It concludes with the identification of three typefaces that contain the required personality traits for DISB. The third stage analyses the anatomy of the three typefaces and proposes a draft Sinhala typeface for DISB. This stage redefines the two variables specific to Sinhala script and typography research. The stage concludes with a summary of the anatomical features of the proposed draft typeface and confirms a list of anatomical features required for Sri Lankan DISBs. The research also contributes to developing a methodology to analyse Sinhala typefaces, and draft new typefaces for specified communicative purposes. As for further research, the research the draft typeface to be developed and tested to font and to adapt to similar scripts and advanced typography research.

In this paper the different salient features of the old and new version of Indian paper currency notes have been studied and compared. The list of security features of Indian currencies have been mentioned and discussed. Various kinds of conventional methods that are used to detect authenticity and to recognize a note has been explained. It has been observed that each technique has its own objective and significance. There are many conventional tools that can be used to recognize different features of a note. To classify different techniques, the detection method comprises of two parts i.e., the first line detection method and the second line detection method. Physical dimensions of a paper note along with its thickness have pointed out a new parameter which is the diagonal of a genuine currency note that has been calculated to obtain a proposed standardization and each value differs from different denominations. The classification of different Indian banknotes giving emphasis on its characteristics, both salient and security features, dimensions and detection methods has been mentioned and briefly explained. For validation of the paper currencies two methods have been discussed emphasizing on fuzzy logic framework by taking into consideration a 3-point Likert scale and another validation methodology using digital image processing.

We present a basketball training visualization method – Motion Time Cylinder (MTC) designed to help novice players learn basketball techniques more easily. The basketball player can select their preferred movement to learn and visualize the body and joint movements in detail. Extensive visualization as a graphical assistant help supports the player in understanding 3D movements from the visual patterns. At the same time, players can understand the coordination and spatial relationship when playing the movement. The visualization principle is based on the mapping of body movement into the graphic of clock-based division locations. The movements can then be represented by the translation pattern between the frontal and transverse planes of cylinder spaces. As a result, the movement can be visualized by rendering the translation pattern base on the clock from a specific perspective, for example, an orthogonal view. This paper explains the visualization principles of the mapping and pattern as well as the graphical representation based on user perception.

This paper explains the visualization principles of the mapping and pattern as well as the graphical representation based on user perception.","PeriodicalId":16019,"journal":{"name":"Journal of graphic engineering and design","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49394098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article is dedicated to the examination of the bookplate of modern Ukraine, which starting from the 1990s entered the state of its revival and flourishing. A version of the bookplate typology, formed on the basis of pictorial motifs as the main classification criteria is proposed, while typologically bookplate is usually divided into groups based on the scope of use or the technique for creating graphic sheets. The reasons for the actualization of bookplate as a type of engraving at the turn of the 20th and 21st centuries, the factors that influenced its popularization outside the country, and the transformation of the functions of bookplate are considered. The role of collecting as one of the most powerful stimuli for the popularization of bookplate in the modern world of graphic arts is emphasized; the leading centers for the development of the bookplate in Ukraine at the beginning of the 21st century and the technique preferred by artists are indicated.
