In addition to depth cues afforded by binocular vision, the brain processes relative motion signals to perceive depth. When an observer translates relative to their visual environment, the relative motion of objects at different distances (motion parallax) provides a powerful cue to three-dimensional scene structure.

Motion parallax is a monocular depth cue arising from the relative velocities of objects moving across the retinae of a moving person. The term parallax refers to a change in position. Thus, motion parallax is a change in position caused by the movement of the viewer.

Motion parallax is a monocular depth cue that causes objects that are closer to you to appear to move faster than objects that are further away. The further away something is, the slower it appears to move. Motion parallax influences how we judge relative distance.

The physiological depth cues are accommodation, convergence, binocular parallax, and monocular movement parallax. Convergence and binocular parallax are the only binocular depth cues, all others are monocular.

Visual cues are concrete objects, pictures, symbols, or written words that provide a child with information about how to do a routine, activity, behavior, or skill. Visual cues can help a child learn a new skill or become more independent with a skill.

Cues are quick verbal or non-verbal reminders of an expected behavior. Visuals are materials used throughout the day to help students remember what they should be doing.

Outside the different types of characteristics and elements , there are seven components of visual communication: Color, Shape, Tones, Texture, Figure-Ground, Balance, and Hierarchy.

Elements of Visual Communication

• Position, color, size, shape, and orientation are variables applied to individual graphic elements.
• Contrast: Elements have noticeably different visual characteristics then others in the composition.
• Repetition: Elements have consistent visual characteristics within the composition.

5 Fundamentals of Visual Communication

• Know Your Audience. To some, this may seem obvious, but just knowing who you’re marketing to isn’t enough.
• Content Length. The medium in which you present your visual content — infographics, ebooks, white papers, case studies, etc.
• Research.
• Visual Accuracy and Flow.
• Content Value.

Visual Communication Design: Principles of design

• Shape.
• Tone.
• Colour.
• Form.
• Point.
• Type.
• Line.
• Texture.

Balance – use this to distribute elements evenly. Contrast – use differences in color, etc. to accentuate elements. Scale – use this to emphasize elements to establish importance or depth. Dominance – use an object’s size, color, etc. to make it stand out.

The elements of visual design — line, shape, negative/white space, volume, value, colour and texture — describe the building blocks of a product’s aesthetics. On the other hand, the principles of design tell us how these elements can and should go together for the best results.

The elements, or principles, of visual design include Contrast, Balance, Emphasis, Movement, White Space, Proportion, Hierarchy, Repetition, Rhythm, Pattern, Unity, and Variety. These principles of design work together to create something that is aesthetically pleasing and optimizes the user experience.

The fundamental principles of design are Emphasis, Balance and Alignment, Contrast, Repetition, Proportion, Movement and White Space. Design differs from art in that it has to have a purpose. Visually, this functionality is interpreted by making sure an image has a center of attention, a point of focus.
