When measuring incomitant deviations with prisms with each eye âfixing,â it is imperative to switch the prism to always be before the non-fixing eye. Otherwise the âfixingâ eye behind the prism will not truly be looking in the intended direction, and major measurement errors can occur.
Gestalt is a general description for the concepts that make unity and variety possible in design. It is a German word that roughly translates as whole or form.. Gestalt theory is involved with visual perception and the psychology of art among other things.
Gestalt theorists followed the basic principle that the whole is greater than the sum of its parts. In other words, the whole (a picture, a car) carried a different and altogether greater meaning than its individual components (paint, canvas, brush; or tire, paint, metal, respectively).estalt is also known as the Law of Simplicity or the Law of Pragnanz (the entire figure or configuration), which states that every stimulus is perceived in its most simple form.
