No, VDU is an output Device.
Visual representation of numbers and figures, to see proportion.
The approximate duration of a visual image in sensory memory is around 250 milliseconds to 1 second. This fleeting storage of visual information allows for the initial processing of incoming stimuli before either being transferred to short-term memory or fading away.

The main types of design principles are balance, contrast, emphasis, proportion, rhythm, and unity. Balance refers to visual stability, contrast creates visual interest through differences, emphasis highlights important elements, proportion ensures visual harmony, rhythm creates a sense of movement, and unity ties all elements together cohesively.
Point and draw Devices. A pointing device is an input interface that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer. Movements of the pointing device are echoed on the screen by movements of the pointer (or cursor) and other visual changes.

Emphasis on the proportion of the human figure is part of the aesthetic principle known as "balance." This principle focuses on the visual equilibrium of elements within a composition, including the size and placement of objects or figures relative to each other. In the context of the human figure, maintaining proportion helps create a sense of harmony and cohesion in the overall visual design.
