## What is iNSIGHT Spatial Vision?

A process called Fourier analysis can be used to mathematically break down any image into a number of basic components. By manipulating these components and then reassembling them, a variety of visual effects can be achieved. This process demonstrates how our visual system analyzes images, and how different types of visual problems can affect our perception of shapes and edges.

iNSIGHT is a curriculum supplement for experimental psychology, sensation and perception, vision science, and optometry lab classes.  There are two different types of iNSIGHT apps: experiments and interactive demonstrations. Experiments are real psychophysical procedures (NOT simulations) that generate real data. Demonstrations illustrate a visual phenomenon and allow students to manipulate the effect.  Each lab is complete with a quick-start guide, detailed instructions, background information, and one or more guided exercises. To see how iNSIGHT works, try the FREE iNSIGHT Color Mixing app.

A printable PDF Student Guide that contains the exercises and other supporting materials, and a Teacher Guide are available at www.polyhedronlearning.com/see_apps_insight.html
