Overview article on orthogonal projection
In the HandsSee method orthogonal projection plays a central role. It is used to illustrate quite exactly the dimensions, proportions and position in space of a 3D-object that is described when objects cannot be touched.
Thus it is an interesting method for everyone who cannot see; both people who recently lost their vision and people who are blind or partially sighted from early youth.
It stimulates spatial awareness, a prerequisite to learn to understand how seeing works - and perspective. That knowledge is important to understand the accompanying explanation of 'next level' tactile images of photo's, paintings and graphic arts with perspective.
Orthogonal projection for HandsSee is the basis for learning to read tactile images. Read about its definitions, history, teaching materials, and options for the future in this overview article on orthogonal projection.
