Definition of designpattern and the value of designpattern in software design

The concept invented by Christoph Alexander for architecture has been taken up and adapted by the software industry. One of the first publications on software pattern was Design Patterns: Elements of Reusable Object-Oriented Software in 1993. Followed by Patterns of Software, Tales from the Software Community by Richard P. Gabriel in 1996. [1] In the article of design pattern a pattern is defined as a solution to a recurring problem in a particular context. (Gamma et al. (1995, page 2-3) ) Dirk Riehle and Heinz Züllighoven define a pattern as mental concept which derives from our experience. Only through past experience can we recognize patterns at all. The recognition of patterns always takes place in retrospect. If there was a good solution to a problem, if we know this solution, if the concept of the solution fits our new problem, we can use it. To do this, it can and in most cases must be adapted and can be improved. A pattern is therefore a template for future solutions based on solutions that have already proven themselves. If the context of the pattern does not fit the context of use, there is a mismatch and adapting the pattern to the new concept could be more work and also more expenses. [2]

A solution which has proven itself through practical application, usefulness and repetition can become a pattern. To meet the requirements of a pattern the solution must be useful, applicable in the similar context and reused by others.[3]

Dirk Riehle and Heinz Züllighoven describe three general pattern types:

Conceptual patterns

Conceptual patterns are a kind of mental model of the work situation and the corresponding system. They are used to understand the user and his tasks. They must be abstract enough to be applicable to other situations, but not too specific, otherwise they cannot be reused. In my opinion, this can be compared to pattern of process, closely related to creating scenarios in the UX process.

Design patterns

Design pattern in software design have nothing to do with surface design, it describes the intent of a pattern and explains problem and solution which can be solved with the pattern. They show the structure and construction of the code and contains objects, classes, inheritance, aggregation and relations. A Framework on the other hand consists of design pattern and components. A pattern is more a best practice, a framework is collection of components based on design pattern. Both concepts follow the same purpose, which is the reuse of former solutions to save time for development.

Programming patterns

A programming pattern is closely related to the specific programming language. It is about programming styles in certain programming languages. [3]

A lot of approaches tried to make software development easier less time consuming, like higher-level programming, languages, object-oriented programming, faster computers, design methodologies, compilers, debuggers, editors, programming environments, automatic programming and artificial intelligence. In 1996 programming was still something not a lot of people are able to do.

Richard Gabriel explains a common problem of this industry by comparing it to craft of building bridges. Bridge building has a long history and profound methods and technologies the engineers can draw upon. These advantages do not exist in software design, and with constantly evolving technology, software engineering must also constantly adapt. [4]

Also the reuse of code, which was supposed to speed up the development process, was not yet mature at that time. Developers had to have a central repository, they had to find the right piece of code, which had to be documented to understand not only the purpose but also the code itself. It is often easier and faster to write the code yourself then to search, find and understand code to reuse it. [5]

A solution for this can be found in design pattern. If programmers know a certain pattern they understand it more easily and can work with it faster. Gabriel compares it with the structure of language – if people know the most common patterns they can use it. [6] A problem can be solved with more than one pattern, so it needs a certain context to work effectively. Using a pattern is also not just copying because it will not work with certain circumstances. [7]

AR in Art

Augmented Reality Art

Was macht man eigentlich bei AR Art? 

Bei Augmented Reality Art geht es darum das „reale“ Kunstwerk um Elemente zu erweitern. Dies kann sich um Sound, Animationen, interaktive Elemente, Bewegung, Verformung oder Farbveränderung handeln. Damit wird die Kunst fesselnder und interessanter, aber auch oft auch verständlicher. 

Mit Hilfe von Augmented Reality ist es uns möglich einem Kunstwerk eine weitere Ebene zu geben, auf der es sich ausdrücken kann. Dabei wird, ohne es aktiv zu wollen, die Geschichte erweitert des Objektes, deshalb ist es besonders wichtig sich zu überlegen in wie weit man in diese Storytelling eingreifen möchte und was man mit der erweiterten Realität ausdrücken möchte.  

AR Ausstellungen haben vor allem während der Pandemie immer mehr Anklang gefunden und sich so ebenfalls schneller als gedacht etabliert. Die Vorteile von Ausstellungen, die komplett mit AR umgesetzt werden liegen auf der Hand, die Ausstellung kann beinahe überall aufgebaut werden und sie kann an mehreren Orten gleichzeitig stattfinden, da sie nicht mehr an die realen Objekte gebunden ist. Ein gutes und eindrucksvolles Beispiel dafür ist die Van Gogh Alive Ausstellungen. Bei einem Besuch taucht man in die Kunstwerke Van Goghs ein und erlebt diese wie noch nie zuvor. 

Weitere Beispiele von AR Ausstellungen sind die Substrata in Los Angeles Museum of Art (LAMOA), die Invisible Landscapes Ausstellung in New York City und der Art Walk in Singapore, der ganz besonders gut zeigt, dass AR genutzt werden kann, um weitere Informationen zu Gebäuden, Kunst o. Ä. Hinzuzufügen, ohne ins Landschaftsbild oder die Architektur eingreifen zu müssen. 

AR Poster

Bei AR Postern handelt es sich, wie das Wort schon sagt, um Plakate und Poster, die um virtuelle Elemente ergänzt werden. AR Poster sind meiner Meinung nach besonders zukunftsträchtig, da sie nicht nur eindrucksvoll sind, sondern auch kostengünstig erstellt werden können. Außerdem finden wir Poster und Plakate überall wo wir hinsehen, sie brauchen nur wenig Platz und sind auch an den entlegensten Orten verbreitet. 

Augmented Reality Poster sind ein Teil von AR Art, aber ich wollte sie noch einmal gesondert ansprechen, da sie für mich nicht nur besonders interessant sind, sondern auch meine Inspiration zu diesem Thema waren. 

Ein besonders eindrucksvolles Beispiel von AR Postern sind für mich die Kunstwerke von Ju Schnee. Vor allem weil sie eine sehr einfache Form verwendet und diese mit Hilfe von AR zum Leben erweckt. Alles was für die AR Installationen seitens der Nutzer gebraucht wird ist ein internetfähiges Smartphone. Nur mit dem Scannen eines QR Codes ist es möglich eine neue Ebene der Kunst zu entfalten. 

Meine nächste Frage ist jedoch: Wie schaffe ich es, dass Leute den QR Code scannen? Wie kann darauf (subtil) aufmerksam gemacht werden, dass es sich um ein AR Poster handelt?

Wie könnte ein Wimmelbuch für Erwachsene aussehen?

Die Nachfrage nach Wimmelbüchern ist unter Erwachsenen gar nicht wenig. Googlet man “Wimmelbuch für Erwachsene” findet man Foren und Seiten, in denen disskutiert und platziert wird, welches Wimmelbuch am Besten für Erwachsene geeignet ist (Bspw. https://www.bestereviews.at/wimmelbuch-erwachsene?targetid=dsa-390857331805&matchtype=&device=c&campaignid=14294937115&creative=539366533150&adgroupid=134541177828&feeditemid=&loc_physical_ms=1000821&loc_interest_ms=&network=g&devicemodel=&placement=&keyword=$&target=&aceid=&adposition=&trackid=at_all_top_1_1&mId=407-132-4411&trackOld=true&gclid=Cj0KCQiA8t2eBhDeARIsAAVEga1l1Xnx6PgqIj8qgcs2YPziDQXO3bw_E5CkPYd1ZIhm5Jynha3MfTkaAuAVEALw_wcB). Die beliebtesten hierbei sind Bücher der Reihe “Pierre, der Irrgarten-Detektiv”. Jedoch wurden diese nicht für Erwachsene gebschrieben. Das Empfohlene Lesealter hierbei ist 5-9 Jahre. Sollte es nicht Wimmelbücher geben, welche nur für Erwachsene gemacht wurden und somit andere Themen visualisieren und vielleicht auch eine andere Wirkung bei den Leser:innen erziehlen? Die einzige 2 Wimmelbücher für Erwachsene, welche ich finden konnte waren “Finde dein Glück” von Daniel Müller und “Wimmel Pimmel – Finde sie alle” von Lem N Love Publishing (eher Satire).

Ich bin der Meinung, dass man hier für mehr Bandbreite sorgen sollte, da es sich um einen Markt mit Potential handeln könnte. In der Zielgruppe sehe ich vor allem gestresste Menschen, die dem Alltag entfliehen möchten und Lesefaule Menschen, die eine bildschirmfreie Möglichkeit zur Entspannung suchen. Außerdem könnte man so gesellschaftlich relevante Themen leicht verlautbar aufbereiten.

Versuch eine Seite zu Zeichnen, wie sie in einem Wimmelbuch für Erwachsene aussehen könnten (Nur Zwischenstand, mehr Details fehlen)

Type design in Arabic

The following paragraphs summarize chapter two of the book “Arabic for Designers: An inspirational guide to Arabic culture and creativity” by Mourad Boutros.

Latin vs. Arabic typography

Latin: written from left to right
Arabic: written from right to left

Latin: letters stand alone (exception: ligatures)
Arabic: combination of connected and single letters

Latin: stretching the letters destroys them
Arabic: stretching is decorative and creates an interesting visual effect (not all letterforms may be stretched, rules exist)

Latin: upper and lower case letters, both can be italicized
Arabic: no upper case letters, italics may look skewed if not executed properly

Latin: baselines from which the heights of ascenders and descenders are established
Arabic: complex system of measurements per basic letter shape, letters hardly sit on the same baseline and the ascenders and descenders vary in length

Latin: each letters has its own shape, ligatures are included in the character set; 52 letters (26 uppercase and 26 lowercase)
Arabic: 7 letters have two shapes, 22 letters have four shapes (start, middle and end of the word, as well as free standing); 18 letters are free standing (cf. Boutros, 2017, p. 44-45)

The role of technology in typeface development

For nearly 400 years after Gutenberg invented printing, type was set by hand. Only in the 19th century typesetting machines were developed to automate the process of composing metal type. Linotype, Intertype, and Ludlow machines cast slugs in fully spaced lines, whereas Monotype machines cast individual pieces of type in justified lines.

In 1949 the next major development came with photographic typesetting. The direct image composition, the ability to combine type and images and the reduced number of steps during the process was a great luxury.

In 1961 Letraset Instant Lettering was developed and considered the most innovative typographic process since hot-metal composition. One sheet measure 9 3/4 by 15 inches, making it easy to store and manage. Within two years, a large variation of typefaces existed in more than four sizes, some even being available in ten sizes. The transfer sheets were manufactured by printing letters in reverse onto one side of a polythene sheet, then overprinting the whole sheet with a low-tack adhesive. After it dried, the sheet would be turned over and the letters are rubbed down onto paper, glass or plastic with a soft-edged tool. At the end, the letters are burnished using a wax-coated interleaver to remove any remains of the adhesive and fixing the letters in position. In 1976 Letraset entered the field of Arabic typography and created more than 50 styles, as well as Arabic decorations (illuminated typefaces, borders, ornaments). Due to the collaboration with experts, the typefaces were renowned for their harmony and versatility. (cf. Boutros, 2017, p. 48-51)

Arabic typesetting

In 1938 the first Monotype keyboard and caster were released for Arabic. A reverse delivery mechanism allowed for the right to left character order. A die case with double-size matrices for deep characters and two-piece matrices for wide characters could deal with the extremes of character shapes. The keyboard was composed of over 200 keyes with four alphabets (separate, initial, medial, final). The typeface used was provided from Monotype’s office in India and had Farsi/Urdu origin. By 1948 a more traditional Naksh from Egypt was used. At that time further technical developments also allowed for the addition of vocalization marks and aesthetic ligatures.

The transition from hot-metal to phototypesetter was the next major development. It abolished the necessity for the complex interlocking of overhanging characters and accents. The phototypesetter used 400 characters, sufficient for complete, regular, and bold character sets, including all accents and ligatures. Three more typefaces were developed: Solloss (traditional Thuluth style), Mudir (semi-bold display face of Farsi origin), and Monotype Kufi Bold.

In 1976 Lasercomp marked the beginning of digital typesetting. By the end of the 70s, the existing five Arabic typefaces were in digital form and two new typefaces, Akhbar and Lakhdar Ghazal, were added.

DecoType tackled Arabic typography in a completely different manner. It used algorithms to arrange glyphs into letter shapes. In 1985 DecoType invented the compact Dynamic Font, which was licensed by Microsoft ten years later (in the form of an OLE server). This was the first smart font on any platform and pioneer in the emerging OpenType technology. The DecoType Advanced Composition Engine (ACE) used 70 typographic primitives (glyphlets) to cover the Riq’a script. Today, the DecoType Nastaleeq Press only needs 422 glyphlets to cover every Arabic-scripted language, without sacrificing kashida (elongating connections) and kerning.

Unicode deals with multilingual texts and is a new dimension of typography. It is a protocol, which facilitates information interchange in all scripts of mankind. Computer typography is confronted with conflicting requirements: minimal size for fast speed on the internet versus a large size for comprehensive language coverage and typographic precision. Nastaliq or Farsi script are used to test type technology due to its huge number of ligatures. Mainstream typographic technology can not handle all the requirements of Arabic script, only the ACE by DecoType covers all aspects of the script. (cf. Boutros, 2017, p. 52-54)

Safe Areas for Videos

When videos are created, there is an element that should be included in the image design. In widescreen formats created for television, cinema, or other devices, for example, there are safety margins that indicate where the title or actions may take place so as not to be cut off on different devices.

The safety margins ought to be made clear to customers, producers, cameramen, editors, and graphic designers. As a video content creator, ignoring the safe margin can mean that many viewers will not see text or other important information in the video (Swanson, 2018).

Cathode ray tubes (CRTs) were once used to project images onto television screens. Some of the image is cut off at the edges due to differences in TV manufacturing and the wear and tear on CRT magnets. The Society of Motion Picture & Television Engineers (SMTPE) has collaborated to develop secure headers and convertible areas to combat this cropping of images. To prevent information from being cut off from the viewer’s screen, these are the areas of the screen where all text and crucial actions should be placed (ibid., 2018).

Source: Swanson, 2018

The safe areas are:

  • 80% of the screen are title safe
  • 90% for the screen are actions safe.

SMTPE updated the safe zone when HDTV format dominated the market. The screen is cut off less by the new safe area than by the old safe area. Title safety is 90%, and action safety is 93%, in the new zones. These updated margins are rarely used, but when they are, they serve as guidelines for weaving errors (like the logo in the corner) and the bottom third (ibid., 2018).

A “centre cut safe” is still required by many broadcasters. This makes sure that the text won’t be cut off at the sides for people who still have old 4:3 TVs. The videos will not pass quality control if they do not meet the safe areas (ibid., 2018).

However, it is still impossible to assume that every TV has a flat screen. Unfortunately, the majority of HD and 4K TVs still have overscan, which can be manually turned off, which causes the edges of the image to be cut off (ibid., 2018).

Online and Social Media Videos

With online videos, there is a mentality of acceptance. A lot of people only use a safe space for aesthetic reasons or because their video is compatible with both the internet and broadcast/cable. Safe spaces are completely ignored in some online videos. The widescreen aspect ratio of different phones varies. Video can be zoomed in so that it appears in full screen mode on all new phones. The picture’s top and bottom are cropped by this zoom. This zoom is set by default on some devices, so many users probably don’t even know about it. The full-screen mode is actively used by other users (ibid., 2018).

Nonetheless, consumers aren’t just using full-screen mode these days. Because not every device has the same aspect ratio, it is essential to create safe areas for actions and titles in portrait formats, which are gaining popularity.

Social media uses the 9:16 format, which is a standard 16:9 video flipped vertically. This aspect ratio is used in Facebook Stories, Instagram Stories, and IGTV to really immerse the viewer and fill the screen. In user Instagram galleries, the traditional square ratio of one to one is frequently used. Their profiles and feeds for followers show these posts. Due to the fact that it takes up more screen space than standard 16:9 videos, it is also a popular format on Facebook. There are also 4:5 and 2:3 aspect ratios, which are a compromise between 1:1 squares and vertical cropping. Instagram uses the 4:5 aspect ratio more often than Facebook, while Facebook only uses the 2:3 aspect ratio. However, since the format alters over time, aspect ratio information must be continually adjusted (Mears, 2019).

Insta-Facery: A Look at How Instagram’s Design Encourages Us to Fake the Perfect Life

On Instagram, people tend to present themselves in a highly curated and idealized way, often portraying an image of a perfect and happy life. This can be achieved through the use of filters, photo editing tools, and selective posting. It’s not uncommon for users to only post the highlights of their lives and to avoid sharing the more mundane or difficult aspects.

Additionally, many users tend to use filters and other editing tools to enhance their photos and to present themselves in the best possible light. These tools can be used to conceal imperfections, to change the lighting and color of a photo, or to add special effects. This can create an unrealistic and misleading representation of a person’s life and appearance.

It’s important to remember that the images we see on Instagram are not always an accurate representation of reality. Many users are presenting an idealized version of themselves, and we should be cautious of comparing our own lives to the filtered and curated images we see on the platform.

There are several reasons why people tend to present themselves in an idealized and curated way on Instagram. One major factor is the desire for validation and attention. Instagram is a platform that is based on likes, comments, and followers, and users may feel pressure to present a positive image in order to gain more engagement and followers.

Another reason is the fear of rejection and the desire to fit in. Instagram can be a highly competitive platform, and users may feel pressure to present themselves in a certain way in order to be accepted by their peers. Additionally, users may also feel pressure to present a certain image in order to be attractive to potential partners or to be successful in their careers.

Instagram’s design also plays a role in encouraging this behavior. The platform’s algorithm prioritizes posts with higher engagement, which means that users who present an idealized image of themselves are more likely to gain visibility and followers. Additionally, Instagram’s features, such as filters and editing tools, make it easy for users to present an idealized image of themselves.

However, this tendency to present an idealized image of oneself can be toxic. It can lead to feelings of inadequacy and low self-esteem among users who feel like they can’t measure up to the curated images they see on the platform. Additionally, it can create a distorted and unrealistic image of reality, which can be harmful for users who are trying to form an accurate understanding of themselves and the world around them.

Moreover, the constant need to present an idealized version of oneself can be time-consuming and can lead to the neglect of real life connections and experiences. It can also lead to a lack of authenticity, which can make it hard for users to form meaningful connections on the platform.

In conclusion, while Instagram’s design can encourage users to present an idealized image of themselves, it’s important to be aware of the potential negative consequences of this behavior and to find a balance between the curated image we want to show and the real one.

[Exploration] AR in Military Operations: Pros, Cons, and Limitations

The military has been using Augmented Reality (AR) technology for several years now and it has proven to be a valuable tool in various operations. AR technology enhances the real-world environment with digital information, providing soldiers with real-time information and data that can improve decision-making and increase situational awareness.

Pros:

  1. Improved situational awareness: AR devices provide soldiers with real-time information about their surroundings, allowing them to make better decisions in the field.
  2. Enhanced training: AR technology can be used to simulate real-world situations, allowing soldiers to train in a more realistic environment.
  3. Reduced risk: By providing soldiers with real-time information, AR technology can help reduce the risk of injury or death in the field.

Cons:

  1. Cost: AR technology can be expensive, and the cost of equipping an entire military unit with AR devices can be significant.
  2. Technical difficulties: AR technology can be complex, and soldiers may struggle to use it effectively in the field.
  3. Dependence on technology: AR technology can create a dependence on technology, potentially reducing soldiers’ ability to make decisions and operate effectively without it.

Limitations:

  1. Limited battery life: AR devices rely on battery power, which can limit their use in the field.
  2. Limited field of view: AR devices often have a limited field of view, which can restrict the amount of information that soldiers can access.
  3. Limited data availability: AR technology relies on data connectivity, and in some remote locations, data may not be available, limiting the effectiveness of AR devices.

In conclusion, AR technology has many potential benefits for the military, including improved situational awareness, enhanced training, and reduced risk. However, there are also several limitations and challenges associated with AR technology, including cost, technical difficulties, and dependence on technology. Despite these limitations, AR technology has the potential to revolutionize military operations, and it will be interesting to see how it continues to evolve in the future.”

Exploring the Challenges of Touchable AR in Commercial Applications

In commercial use, AR can be implemented in a variety of ways. Retail businesses can use AR to enhance the shopping experience by allowing customers to see how a piece of furniture or clothing would look in their home or on their body before making a purchase. In manufacturing, AR can be used to assist workers in assembly and repair tasks by providing them with digital instructions and guidance overlaid onto the physical objects they are working on.

However, there are also challenges with implementing AR in commercial use. One of the main challenges is creating a seamless and natural user experience. Touchable AR, which allows users to interact with digital objects in the real world, is particularly challenging. This is because creating a realistic and responsive touch experience requires sophisticated sensors and haptic technology. Additionally, there is a lack of standardisation in the field, which makes it difficult for developers to create consistent and user-friendly experiences across different devices and platforms.

Another problem with touchable AR is related to the technology’s immaturity. The technology is still being developed and improved, so it’s not yet possible to provide a seamless and realistic touch experience in all cases. Furthermore, the cost of creating touchable AR experiences can be high, which can make it difficult for small businesses to afford.

In conclusion, while AR has many potential uses in commercial applications, there are also significant challenges to overcome in order to create a seamless and natural user experience. Touchable AR, in particular, is a complex and expensive technology that requires sophisticated sensors and haptic technology. As the technology continues to evolve, it will be important for businesses to stay up-to-date with the latest developments in order to create the best possible experiences for their customers.

Historical background of the Arabic language

After receiving the book “Arabic for Designers. An inspirational guide to Arabic culture and creativity” by Mourad Boutros, I was able to dive deeper into the importance of Arabic as a language, its historical background, as well as its cultural context. In this post I will summarize my findings from studying the introduction and the first chapter of the book.

The importance of understanding another culture

When trying to either work for a client of different cultural background, or trying to target the market of another culture, doing research to understand said culture is essential. If one ignores this step in the process, the whole project might turn into a disaster. In case of Arabic, people have made fundamental mistakes in the past, such as not taking into account that the language is not read from left to right, but actually the other way around. (cf. Boutros, 2017, p. 7)

Even as cultures today are merging and ever-changing, core elements and beliefs of cultural and national identities remain unchanged. When companies or individuals try to appeal to their target market, these long-established tendencies can not be ignored. An example of a failed attempt to reach a market with a different cultural background is Google. The search engine is still not the go-to choice for most users in Japan, since they tried to conquer the market with the same visual identity that worked for Americans and Europeans. However, the taste of Japanese internet users is different – they enjoy complex websites, decorated with texts and graphics, not the simple and clean look of Google. Furthermore, they also made major mistakes when introducing Google Maps to the Japanese market. The company made major mistakes, such as taking pictures of people’s backyards, which goes strictly against the country’s values of privacy. They also ignored the importance of public transport in Japan and directed people to a town’s geographical centre, instead of their bus or train stations. There were also inaccuracies in the historical maps, which led to disfavour towards Google from the Japanese. (cf. Boutros, 2017, p. 11)

The origins of the Arabic language

Together with Aramaic and Hebrew, Arabic belongs to the Semitic languages. Arabic is historically the last of the Semitic scripts, which are all read from right to left. The language spread throughout the world along with the religion of Islam and can be divided into two general groups: Classical Arabic and Modern Standard Arabic. The first is the language of the Holy Qur’an and pre-modern texts, the second is the language of media and most scholarly and literary texts. Arabic consists of 28 consonantal signs (three are also used as long vowels). Due to the tradition of passing down poetry and literature orally, written text was not widespread until the beginnings of Islam. Therefore, each calligrapher had his own style and no explicit rules existed. The shape of script held just as much meaning as the content, as the language relied heavily on its visual appearance to convey meaning. There is a common agreement among scholars, that the Arabic script had its origins in the Nabataean script dating from the 3rd century. It took another four centuries, until the 7th century, that written words became of importance. (cf. Boutros, 2017, p. 22)

The influence of Islam

Muslims believe that Angel Gabriel revealed the Holy Qur’an to Muhammad between the years AD 610 and 632. They also believe, that while other holy texts such as the Bible or the Torah have been misinterpreted or forgotten, their Holy Qur’an is the embodiment of perfection. This created the need to capture every single word of the holy text in exact detail and therefore only relying on memory was not sufficient anymore. Islam heavily influenced the devlopment of Arabic calligraphy – it was transformed, improved and beautified. The reason for the aesthetic development of the script was to make it worthy of transmitting God’s divine message. Calligraphy also served as a tool for articistic expression, since figurative art was banned under strict interpretations of Islam. In 651 the first copies of the Holy Qur’an were written in two local variants of Jazm, Mecca and Medina. Soon they were superseded by Kufic, which got its name from the town Kufa located in Iraq. In the early history of Arabic writing, 150 different types of the Kufi script existed, leading to a large amount of variation. Arabic used to be written without any diacritic points, until the language’s development of inserting diacritic points to mean different things depending on the positioning. They were added in the form of red dots and strokes: On the top it stands for the sound ‘a’, on the letter itself for the sound ‘ou’ and below the line for the sound ‘e’. The introduction of diacritic points greatly helped non-Arabic speakers to understand and pronounce the phonetics properly and to read the Holy Qur’an. This process was therefore called Ta’jim, which comes from the word Ajam, meaning non-Arabic speakers. (cf. Boutros, 2017, p. 25)

The development of Arabic script

With the spread of Islam, many cursive scripts were developed and became prominent. All of them vary in style, because of the scriptwriters’ individual tastes.

Nakshi

It is one of the earliest cursive scripts and became popular in the 10th century. Due to its high legibility it was used for copying the Holy Qur’an. Characteristics are the short horizontal stems and the almost equal vertical depth above and below the medial line. Today Nakshi is used for headings, subheadings and body text in newspapers, books or advertising and remains as one of the most widely used Arabic style.

Ta’liq

It was first developed in Persia during the 15th century and later spread to Turkey and the Indian subcontinent. It is characterized by its fluidity and the varying thickness of the strokes. Today it is still used for newspapers and magazines in Iran, Afghanistan, and Pakistan where handwritten calligraphy is still popular.

Diwani

Diwani is based on Ta’liq, but has less dramatic hanging baselines. It evolved in the 16th century in Turkey and there also exists a decorative version known as Diwani Jali, which is widely used for ornamental purposes.

Riq’a

Riq’a has its origins in the 15th century, but only became popular in the 19th century. It is characterized by thick round curves and widely used in Egypt today (in the form of Egyptian Rokaa, a wider and airier verion of the original).

Thuluth

Thuluth can be traced back to the 7th century, but did not become to prominence until the late 9th century. Its thin fluid lines are used for calligraphic inscriptions, titles and headings. (cf. Boutros, 2017, p. 26-27)

The Kufic script

In the 8th century, the Kufic script achieved a level of perfection. Therefore it was used to transcribe the Holy Qur’an and was the dominant Qur’anic script for more than 300 years. It is characterized by static rectangular lines, short vertical strokes and extended horizontal lines.

The calligrapher Abu ‘Ali Muhammad Ibn Muqlah standardized the major cursive styles and created a comprehensive system of calligraphic rules. He redesigned the letterforms by using three standard units for measurement: the rhombic dot, the Alif, and the circle.

Alif

The Alif is equivalent to the letter ‘A’ in the Latin alphabet and was a vertical stroke measuring between 6 and 8 rhombic dots. The number of dots varied according to the particular style.

Circle

The standard circle has a radius equal to the height of the Alif.

Rhombic dot

The rhombic dot is the same size as the tip of a bamboo calligraphy stick. (cf. Boutros, 2017, p. 28)

The effect of Greenwashing and how to avoid it

Greenwashing is defined as “to make people believe that your company is doing more to protect the environment than it really is” (https://dictionary.cambridge.org/dictionary/english/greenwash). This is done to attract customers. Business Wire writes that there is a “significant global paradigm shifts in how consumers view sustainability and the associated generational differences in willingness to pay for sustainable products and services,” (The Global Sustainability Study 2021 by Simon-Kucher & Partners).(https://www.businesswire.com/news/home/20211014005090/en/Recent-Study-Reveals-More-Than-a-Third-of-Global-Consumers-Are-Willing-to-Pay-More-for-Sustainability-as-Demand-Grows-for-Environmentally-Friendly-Alternatives). This leads to a wish for companies to seem sustainable, even though they might not have the right or the knowledge to call themselves that. This leads to a gap between claims and truth. 

Greenwashing

“Research carried out in Europe found that 42% of green claims were exaggerated, false, or deceptive” Harvard Business Review (HBR) writes (2022) about a “sweep” of websites carried out by the European Commission and national consumer authorities. They found this:

  • In 37% of the cases included vague terms like “conscious” and “eco-friendly”
  • In 57% of the cases there was no easily accessible evidence to back up the claims that were made

(https://hbr.org/2022/07/how-greenwashing-affects-the-bottom-linehttps://ec.europa.eu/commission/presscorner/detail/en/ip_21_269)

HBR found that customers realize and are aware of the gap between the claims and actually actions enough to impact their satisfaction levels with the companies. This carries out to affect their relationship with the products and it affects the economy for the company in an impactful way. However, the customers “only care to a point.” If a company is seen as a high quality, innovative etc. brand, the satisfaction levels of the customers were unsignificantly affected even if the company was perceived as greenwashing. This result should, according to HBR, still be read with caution as a bigger or later research could show a greater effect.

How to avoid greenwashing, but still communicate sustainability

What HBR advices is that managers should pay equal attention towards their communicating their goals outwards and to their companies ability to achieve these. It is better as a company to promise something achievable and overachieve than the opposite. (https://hbr.org/2022/07/how-greenwashing-affects-the-bottom-line) This tactic can be seen in one of my previous posts about Northern Playground, and their communication outwards about how “no fashion is sustainable”. They still manage to communicate that their clothing is of the better alternatives if used right without risking a backlash for not being carbon neutral.

In addition to paying better attention to what is communicated outwards in statements, it can also be useful to use voluntary standards. E.g. EcoLabel Index (https://www.ecolabelindex.com) provides a vide variety of labels which can be used to legitimatize a companies claims. Here there is also room for mistakes, as many of the labels can be completely in-relevant or weak. Using recognizable and well known labels will likely give the best effect.

Avoiding greenwashing should be a high priority, but that doesn’t mean a company shouldn’t strive to reach high. As HBR writes it: “It may well be the case that they (ed. customers) are willing to forgive companies that tried and legitimately failed to implement their goals but customers might also be less forgiving towards those companies that attempted to cheat their way by exaggerating their credentials.” (https://hbr.org/2022/07/how-greenwashing-affects-the-bottom-line)
