Visual communication is the use of visual elements to convey ideas and information which include but are not limited to signs, typography, drawing, graphic design, illustration, industrial design, advertising, animation, and electronic resources.[1] Humans have used visual communication since prehistoric times.[2] Within modern culture, there are several types of characteristics when it comes to visual elements, they consist of objects, models, graphs, diagrams, maps, and photographs.[3] Outside the different types of characteristics and elements, there are seven components of visual communication: color, shape, tones, texture, figure-ground, balance, and hierarchy.[3]

Each of these characteristics, elements, and components play an important role in daily lives. Visual communication holds a specific purpose in aspects such as social media, culture, politics, economics, and science. In considering these different aspects, visual elements present various uses and how they convey information.[4] Whether it is advertisements, teaching and learning, or speeches and presentations, they all involve visual aids that communicate a message. In reference to the visual aids, the following are the most common: chalkboard or whiteboard, poster board, handouts, video excerpts, projection equipment, and computer-assisted presentations.[5]

Overview
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.[6] 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.[7] 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.[8]

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.[9]

Important figures
Aldous Huxley is regarded as one of the most prominent explorers of visual communication and sight-related theories.[10] 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.[11]


 * 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 though many perspectives, for example these six major perspectives presented by Paul Martin Lester: Personal, Historical, Technical, Ethical, Cultural, and Critical.[12]


 * 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, even though the image can be seen in other ways.[12]


 * Historical perspective: An image's view can be arising from the history of the use of media. Through times sort images have been changed, because the use of different (new) media. For example: The result of using the computer to edit images (e.g. Photoshop) is quite different when comparing images that are made and edited by craft.[12] Technical perspective: When the view of an image is influenced by the use of lights, position and the presentation of the image. The right use of light, position and presentation of the image can improve the view of the image. It makes the image looks better than the reality.[12]


 * Ethical perspective: From this perspective, the maker of the image, the viewer and the image itself must be responsible morally and ethically to the image. This perspective is also categorized in six categories: categorical imperative, utilitarianism, hedonism, golden mean, golden rule, and veil of ignorance.[12]


 * Cultural perspective: Symbolization is an important definition for this perspective. Cultural perspective involves identity of symbols. The uses of words that are related with the image, the use of heroes in the image, etc. are the symbolization of the image. The cultural perspective can also be seen as the semiotic perspective.[12]


 * Critical perspective: The view of images in the critical perspective is when the viewers criticize the images, but the critics have been made in interests of the society, although an individual makes the critics. This way this perspective differs from the personal perspective.[12]

Visual aid media: Simple to advanced

 * Chalkboard or whiteboard: Chalkboards and whiteboards are very useful visual aids, particularly when more advanced types of media are available. They are cheap and also allow for much flexibility.[13] 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.[13]


 * Poster board: A poster is a very simple and easy visual aid. Posters can display charts, graphs, pictures, or illustrations. The biggest drawback of using a poster as a visual aid is that often a poster can appear unprofessional. Since a poster board paper is relatively flimsy, often the paper will bend or fall over. The best way to present a poster is to hang it up or tape it to a wall.[13]
 * Handouts: Handouts can also display charts, graphs, pictures, or illustrations. An important aspect of the use of a handout is that a person can keep a handout with them long after the presentation is over. This can help the person better remember what was discussed. Passing out handouts, however, can be extremely distracting. Once a handout is given out, it might potentially be difficult to bring back your audience's attention. The person who receives the handout might be tempted to read what is on the paper, which will keep them from listening to what the speaker is saying. If using a handout, the speaker distributes the hand out right before you reference it.[14] 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.[13]
 * 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.[13]
 * 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.[13]
 * 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.[13]

Components
Components of visualization make communicating information more intriguing and compelling. The following components are the foundation for communicating visually. Hierarchy is an important principle because it assists the audience in processing the information by allowing them to follow through the visuals piece by piece. When having a focal point on a visual aid (i.e. Website, Social Media, Poster, etc...), it can serve as a starting point for the audience to guide them. In order to achieve hierarchy, we must take into account the other components: Color, Shape, Tones, Texture, Figure-Ground, Balance.[9]

Colors is the first and most important component when communicating through visuals. Colors displays an in-depth connection between emotions and experiences. Additive and subtractive color models help in visually communicating aesthetically please information.[9] Additive color model, also known as RGB color (Red, Green, Blue) goes from dark to light colors, while subtractive color model is the opposite. The subtractive color model includes the primary CMYK colors (Cyan, Magenta, Yellow, Black) which go from light to dark.[15] Shape is the next fundamental component that assists in creating a symbol that builds a connection with the audience. There are two categories that shapes can fall under: Organic or Biomorphic shapes, and Geometric or Rectilinear shapes. Organic or biomorphic shapes are shapes that depict natural materials (which include curvy lines), while Geometric or Rectilinear shapes are shapes that are created by man (including triangles, rectangles, ovals, and circles).[9]

Tone refers to the difference of color intensity, meaning more light or dark. The purpose of achieving a certain tone is to put a spotlight on a graphical presentation and emphasize the information. Similarly, texture can enhance the viewers optics and creates a more personal feel compared to a corporate feel. Texture refers to the surface of an object, whether is it 2-D or 3-D, that can amplify a user's content.[9]

Figure-ground is the relationship between a figure and the background. In other words, it is the relationship between shapes, objects, types, etc. and the space it is in. We can look at figure as the positive space, and ground as the negative space. In comparison, positive space is the objects that hold dominance visually, while negative space (as mentioned previously) is the background. In addition to creating a strong contrast in color, texture, and tone, figure-ground can highlight different figures. As for balance, it is important to have symmetrical or asymmetrical balance in visual communication. Symmetrical balance holds a stable composition and is proper in conveying informative visual communication. As for asymmetrical balance, the balance of visuals is weighted more to one side. For instance, color is more weighted to one color than the other, while in a symmetrical balance all colors are equally weighted.[9]
