pointer straw
One of the most fundamental activities we use our visual process for is to guide purposeful movements. Placing a small object, like a pointer, into an opening, such as a straw, particularly when done slowly, demands a lot of the person. There is great benefit which emerges as a result of the symmetrical use of the visual process during this activity. For some, it may be THE activity which helps them come face-to-face with what it feels like to use their visual process in a symmetrical way. You can experiment with various sizes of pointer type objects and objects with opening of different sizes depending on the needs of the patient at the time. What is seen the these videos has more of a fine just noticeable difference (JND) feel with a small pointer and small diameter straw. Feel free to use paper towel tubes etc.
