Visual communication as the name suggests is communication through visual aid and is described as the conveyance of ideas and information in forms that can be read or looked upon. Visual communication solely relies on vision, and is primarily presented or expressed with two dimensional images, it includes: signs, typography, drawing, graphic design, illustration, color and electronic resources. It also explores the idea that a visual message accompanying text has a greater power to inform, educate, or persuade a person or audience

The evaluation of a good visual design is mainly based on measuring comprehension by the audience. However, personal aesthetic and/or artistic preference may also effect the meaning of the image, as there are no universally agreed-upon principles of beauty and ugliness. Excluding two dimensional images, there are other ways to express information visually - gestures and body language, animation (digital or analogue), and film. Visual communication by e-mail, a textual medium, is commonly expressed with ASCII art, emoticons, and embedded digital images.
