Conceptual Art vs Perceptual Art

Conceptual art is art in which the concept(s) or idea(s) involved in the work take precedence over traditional aesthetic and material concerns. Many of the works, sometimes called installations, of the artist Sol LeWitt may be constructed by anyone simply by following a set of written instructions.^[1This method was fundamental to LeWitt's definition of Conceptual art, one of the first to appear in print:

 

"In conceptual art the idea or concept is the most important aspect of the work. When an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. The idea becomes a machine that makes the art.
Sol Lewiss

In simple words, conceptual art is the art that is intended to convey an idea or concept to the perceive and need not to involve the creation or appreciation of a tradition art object such as painting or sculpture. It also can be defined as art in which the idea behind the particular work, and the means of producing it, are more important than the finish work.

"Perceptual Art is a form of art that can trace its roots to the art history concepts of perceptual-ism as well as to twentieth century inventions of conceptual art and performance art."

 In practice, perceptual art may be interpreted as the engagement of multi-sensory experiential stimuli combined with the multiplicity of interpretive meanings on the part of an observer. Sometimes, the role of observer is obscured as members of the public may unwittingly or unknowingly be participants in the creation of the artwork itself.
