They are called "Touch Quilts".
A few years ago, we made six or eight of these and gave them to Nursing Homes for the Alzheimer's patients. They were squares or other shapes of fabrics of many different textures. We had satin, corduroy, demin, lace, fur (lots of different furs), net - - - we put in every different texture we could find. They were small, only about 20X30 inches.
These are also used for blind babies to learn how to crawl. They love feeling the different blocks and will try to find one they like, so they have to crawl to find it.
