[accessibleimage] Looking for research

Hello List:

     I am looking for research that addresses the effectiveness of tactile 
graphics and three dimensional models as educational materials. Of course I 
believe that tactile graphics and models are valuable, but has their usefulness 
actually been studied? I have been searching with Google, and so far, haven't 
found usable information. Thank you.

Regards,
