Recommendation #1: Visual accommodations and Activity

To help Mr. S. track an object, materials used in instruction should include visual accommodations such as considering the size of the objects, the contrast between the object and the background, and spacing between the object and surrounding background objects. He relies on using his right eye because of his Ptosis (drooping eyelid on his left eye) and his visual field is limited. Angle and height of the AT devices position must be taken into consideration. For example, during a learning activity, use a brightly colored object on a large black paper as a background (e.g., hanging against the wall), instead of having him face the entire classroom, may allow him to control his eye and focus on the target. Use of a mounting system for an AAC or an iPad will help him see the objects on the screen.

Activity:Practice focusing one object (or target) by using low-tech (e.g. bright color) and expand to Yes and No activity by using his eye. 

If a Smartboard or a projector is available for Steven to use, then enlarging the objects on the screen can help him expand his learning with other students.
