I want to tell you all this......my Dad has PSP and has an ipad that is suppose to help, a tango that is suppose to help. I think that ANYTHING like that is great for earlier stage PSP. For my Dad who can't seem to perform the smaller movements, I have come up with a GENIUS, and I do mean GENIUS plan. (So modest aren't I)
Taped four 8 by 10 pieces of paper together. Neatly wrote the alphabet about 3 1/2 to 4 inches tall.....taped it to the TV (which is eye level for him). You can flip it behind the TV when we aren't using it, THEN, I took my little red laser light that I use to play with my cat. Now, dad can spell what he is trying to say, simply by pointing the laser at each letter!! I am telling you, it's amazing.
It requires bigger movements, so he does very well.
I hope this helps others, you all have been so helpful to me. I can't wait to see how others make out!
