Visual communication: as the name implies, is a method of communication through sight. Visual communication is a process of delivering a series of will or specific intent to others with the use of media depictions which can only be read by the sense of sight. It combines art, symbols, typography, drawing, graphic design, illustration, and color in its delivery.
Visual communication has several functions such as the means of information and instructions, it aims to show the relation between one thing with another in the guidance, direction, position and scale, such as maps, diagrams, symbols and directions. The information will be useful when communicated to the right people, at the right time and place in a form that can be understood and presented in a logical and consistent.
As a means of presentation and promotion of the message: get attention (attention) of the eye (visually) and make the message memorable; eg posters.
As a means of identification: one can reveal the identity of the origin of such a person. Likewise, an object, product or institution, with an identity that would reflect the quality of the product or service and is easily recognizable by both producers and consumers. We would be easier to buy cooking oil by mentioning the brand 'X' size 'Y' rather than just saying buy a liter of cooking oil. Or maybe you are going to buy cooking oil brand 'X' because of its logo that seemed clear, clean, and "healthy".
When visual communication is used for the identification of institutions such as schools. Then people will be easier to decide between school A or B as favorites, as they often excel in the arena of national and ranks highest in the region.
Visual communication has some basic theory that can be used as a benchmark in its functions, namely: sensual and perceptual theories.
VISUAL COMMUNICATION DISCUSSION
Psychologists, philosophers, and practitioners have devised several approaches that can help us explain how to view and process the images. The four theories that we discuss can be divided into two basic groups: sensual (gestalt and constructivisme) and perceptual (and cognitive semiotics).
THE DIFFERENCE BETWEEN VISUAL SENSATION AND VISUAL PERCEPTION
To understand one approach to visual communication, you must first know the difference between visual sensation and visual perception.
Visual sensation of a stimulus from the outside world that activates nerve cells in the organ of your senses. Burning wood in a fireplace can activate cells in your ear as you could hear the crack and sizzle sticks; You can smell the aroma of the wood in your nose; You can feel the warmth of the fire through the hands and face, and in your eyes when you see the light yellow from the flames. When the stimulus reaches the brain, it can produce a sense of all the sensual input. Your brain interprets the sounds, smells, temperature, and sights such as the fire in the fireplace.
Visual perception is the conclusion made by combining all of the information collected by your sensual organs. Sensation is raw data. Visual perception is the inference of meaning after visual stimuli received.
CONCLUSION
Visual communication is the process of delivering a number of specific requirements or purpose to others through the use of media depiction which can only be read by the sense of sight.
Visual communication using art, symbols, typography, pictures, graphic design, illustration, and color in its delivery. Visual perception is the conclusion made by combining all of the information collected by your sensual organs. Sensation is raw data. Visual perception is the conclusion meaning after visual stimulus received.
There are four theories discussed are divided into two groups of policies: sensual (Gestalt and constructivisme) and perceptual (semiotics and cognitive). In curriculum and educational technology, an educational technologist in planning learning requires knowledge about the signs in semiotics, requires knowledge that supports the dissemination of information as well as other policy theories of visual communication, so that the messages conveyed by the students accepted in full.
