Visual communication

The debate about the nature of visual communication dates back thousands of years. Visual communication relies on a collection of activities, communicating ideas, attitudes, and values via visual resources, i.e. text, graphics, or video. The evaluation of a good visual communication design is mainly based on measuring comprehension by the audience, not on personal aesthetic and/or artistic preference as there are no universally agreed-upon principles of aesthetics. Visual communication by e-mail, a textual medium, is commonly expressed with ASCII art, emoticons, and embedded digital images. Visual communication has become one of the most important approaches using which people communicate and share information. The term 'visual presentation' is used to refer to the actual presentation of information through a visible medium such as text or images. Recent research in the field has focused on web design and graphically-oriented usability. Important figures Aldous Huxley is regarded as one of the most prominent explorers of visual communication and sight-related theories. Becoming near-blind in his teen years as the result of an illness influenced his approach, and his work includes important novels on the dehumanizing aspects of scientific progress, most famously Brave New World and The Art of Seeing. He described "seeing" as being the sum of sensing, selecting, and perceiving. One of his most famous quotes is "The more you see, the more you know." Max Wertheimer is said to be the father of Gestalt psychology. Gestalt means form or shape in German, and the study of Gestalt psychology show emphasis in simplicity, as its properties group visuals by similarity in shape or color, continuity, and proximity. Additional laws include closure and figure-ground principles in studied images is also intensively taught. Kurt Koffka and Wolfgang Köhler are also prominent figures in early visual communication research. Image analysis Visual communication contains image aspects. The interpretation of images is subjective and to understand the depth of meaning, or multiple meanings, communicated in an image requires image analysis. Images can be analyzed through many perspectives, for example these six major perspectives presented by Paul Martin Lester: Personal, Historical, Technical, Ethical, Cultural, and Critical. • Personal perspective: When a viewer has an opinion about an image based on their personal thoughts. Personal response depends on the viewer's thoughts and values, individually. However, this might sometimes conflict with cultural values. Also when a viewer has viewed an image with a personal perspective, it is hard to change the view of the image on the viewer, . The use of chalkboards or whiteboards is convenient, but they are not a perfect visual aid. Often, using this medium as an aid can create confusion or boredom. Particularly if a student who is not familiar with how to properly use visual aids attempts to draw on a board while they are speaking, they detract time and attention from their actual speech. Distributing handouts is acceptable in a lecture that is an hour or two, but in a short lecture of five to ten minutes, a handout should not be used. • Video excerpts: A video can be a great visual aid and attention grabber, however, a video is not a replacement for an actual speech. There are several potential drawbacks to playing a video during a speech or lecture. First, if a video is playing that includes audio, the speaker will not be able to talk. Also, if the video is very exciting and interesting, it can make what the speaker is saying appear boring and uninteresting. The key to showing a video during a presentation is to make sure to transition smoothly into the video and to only show very short clips. • Projection equipment: There are several types of projectors. These include slide projectors, overhead projectors, and computer projectors. Slide projectors are the oldest form of projector, and are no longer used. Overhead projectors are still used but are somewhat inconvenient to use. In order to use an overhead projector, a transparency must be made of whatever is being projected onto the screen. This takes time and costs money. Computer projectors are the most technologically advanced projectors. When using a computer projector, pictures and slides are easily taken right from a computer either online or from a saved file and are blown up and shown on a large screen. Though computer projectors are technologically advanced, they are not always completely reliable because technological breakdowns are not uncommon of the computers of today. • Computer-assisted presentations: Presentations through presentation software can be an extremely useful visual aid, especially for longer presentations. For five- to ten-minute presentations, it is probably not worth the time or effort to put together a deck of slides. For longer presentations, however, they can be a great way to keep the audience engaged and keep the speaker on track. A potential drawback of using them is that it usually takes a lot of time and energy to put together. There is also the possibility of a computer malfunction, which can mess up the flow of a presentation. == Visual literacy ==

Studies often define visual literacy (or visual competence) as the ability to understand and process what is being seen in order to make sense of the world. Being visually literate has been shown to be an important aspect of life to those with sight. The function of sight itself has mechanisms that must work together in order to transform the lines, shapes, and colors around a person's environment into a cohesive picture that can then hold meaning. These mechanisms are what occur in the human body that allow a person's eye to make sense of what the viewer sees and then the signals that are sent to relay information to their brain to be processed. However, studies conducted state that visual intelligence is not something that is taught but rather observed. It is also noted within this study that this skill often goes unnoticed until it is impaired. This act of processing what is being seen has been shown to happen quickly and oftentimes without the viewer's cognizant awareness. The effect visual literacy has on a viewer has also been shown to influence aspects of their life such as, attitudes, values, beliefs, as well as cultural views. Scholars have noted how society and culture is often dominated by imagery, especially with the rise of mass technological media. The dominance of visuals in culture such as film, television and social media, have now been used by various companies for their advertisements. Presidential and political candidates have also turned to the media to visually promote their campaigns. With many of these advertisements present in everyday life, the viewers of this content may often be open to influence without being cognizant of it. == Study of symbols ==

Semiotics Semiotics is the study of signs and visuals within society that relay meaning. The symbols used in different cultures to convey a meaning also entails the hidden systems and functions that make up the symbols. Logos, gestures, and technological signs such as emoticons, are a few examples of symbols used in culture. The term semiology is the study of signs and symbols and their arrangements as a visual language. The characterization of what is considered a language is the existence of an alphabet that can be arranged to create meaning. An example of signs, or an alphabet, that can be arranged to create meaning are the 26 letters that make up the Modern English Alphabet which can then be used to compose written messages that can then be relayed orally. However, in semiology, the signs that create the alphabet of visual communication are more abstract than a written or verbal languages alphabet. In comparison to the English Alphabet, the visual alphabet is still being studied due to the various channels that may be used to relay visuals. Components of a still graphic compared to film, for instance. Another category of study within the field of semiotics is how the interpretation of visual signs depends on the experiences of the person interpreting the visual components of symbols, commonly referred to as the interpretant. Theory of semiotics Collectively, the study of visual imagery and gestures as a language has two major schools of thought. The contributors who are commonly referred to are; Charles Sanders Peirce and his descendants and Ferdinand de Saussure. Peirce's school of thought is the meaning that the interpreter assigns to a particular sign instead of the study of the sign itself. His work focuses on the pragmatics, semantics, and structure of a symbol in visual communication. Saussure, however, focused primarily on the structure and value of a sign and its relation to other symbols within the language system. The school of thought that Saussure curated contributed to the rise of structuralism as well as later theories developed by various scholars in the field of communication. == Prominence and motive ==

Social media Social media is one of the most effective ways to communicate. The incorporation of text and images deliver messages quicker and more simplistic through social media platforms. A potential drawback can be there is limited access due to the internet access requirement and certain limitations to the number of characters and image size. Despite the potential drawback, there has been a shift towards more visual images with the rise of YouTube, Instagram, and Snapchat. In the rise of these platforms, Facebook and Twitter, have followed suit and integrated more visual images into their platform outside the use of written posts. It can be stated that visual images are used in two ways: as additional clarification for spoken or written text, or to create individual meaning (usually incorporating ambiguous meanings). These meanings can assist in creating casual friendships through interactions and either show or fabricate reality. These major platforms are becoming focused on visual images by growing a multi-modal platform with users having the ability to edit or adjust their pictures or videos these platforms. • Identity construction: Similar to genres, users will use visuals through social media to express their identities. Visual elements can change in meaning over a period of time by the person who shared it, which means that visual elements can be dynamic. This makes visuals uncontrollable since the person may not identify as that specific identity, but rather someone who has evolved. When considering visual culture in communication, it is shaped by the values amongst all cultures, especially regarding the concepts of high and low-context. Cultures that are generally more high-context will rely heavily on visual elements that have an implied and implicit meaning. However, cultures that are low-context will rely on visual elements that have a direct meaning and rely more on the textual explanations. Visual communication can be defined in different ways (Volli 1994). An effective one is through opposition with signification (Volli 2010). Whereas visual signification can be unintentional, there is no communication without intentionality. A sunset signifies something, whereas a painting signifies something but also communicates, because culture marks it as product of communicative intentionality. However, imputation of intentionality changes across cultures and epochs. Whereas religion may see a sunset as a divine message, secular observers will attach to it an unintentional meaning of nostalgia. Politics Visual communication in politics have become a primary sense of communication, while dialogue and text have become a secondary sense. This may be due to the increased use of televisions, as viewers become more dependent on visuals. Sound bite has become a popular and perfected art among all political figures. Despite it being a favored mode of showcasing a political figure's agenda, it has shown that 25.1% of news coverage displayed image bites - instead of voices, there are images and short videos. Visuals are deemed an essential function in political communication, and behind these visuals are 10 functions for why political figures use them. These functions include: • Argument function: Although images do not indicate any words being said, this function conveys the idea that images can have an association between objects or ideas. Visuals in politics can make arguments about the different aspects of a political figure's character or intentions. When introducing visual imagery with sound, the targeted audience can clarify ambiguous messages that a political figure has said in interviews or news stories. On the other hand, research has suggested that the logic and rationality of a viewer is not barred by emotion. In fact, logic and emotion are interrelated meaning that images not only can have emotional arousal, but also influence viewers to think logically. • Image-building function: Imagery gives a viewer a first impression of a candidate when they are running for office. These visuals give voters a sense of who they will be voting for during the elections, regarding their background, personality, or demeanor. They can create their image by appearing be family-oriented, religiously involved, or showing a commonality with the disadvantaged community. Similar to the other aspects of why visual elements are used, graphs are used by economists to clarify complex ideas. Graphs simplify the process of visualizing trends that happen over time. Along the same lines, graphs are able to assist in determining a relationship between two or more variables. The relationship can determine if there is a positive correlation or negative correlation between the variables. A graph that economists rely heavily on is a time-series graph, which measures a particular variable over a period of time. The graph includes time being on the X-axis, while a changing variable is on the Y-axis. Science and medicine Science and medicine has shown a need for visual communication to assist in explaining to non-scientific readers. From Bohr's atomic model to NASA's photographs of Earth, these visual elements have served as tools in furthering the understand of science and medicine. However, using visual elements can have a negative effect on the understanding of information. Two major obstacles for non-scientific readers is: 1.) the lack of integration of visual elements in every day scientific language, and 2.) incorrectly identifying the targeted audience and not adjusting to their level of understanding. To tackle these obstacles, one solution is for science communicators must place the user at the center of the design, which is called User-Centered Design. This design focuses on strictly the user and how they can interact with the visual element with minimum stress, but maximum level of efficiency. Another solution could be implemented at the source, which is university-based programs. In these programs, universities need to introduce visual literacy to those in science communication, helping in producing graduates who can accurately interpret, analyze, evaluate, and design visual elements that further the understanding of science and medicine. ==See also==
