My wife seen an IPAD the other day and it contained special learning program - which our disabled son can use. However, his fine motor skills are low. Vision fine motor skills of a 3-5 year old. With the iPad, is there a method to "slow down" its motion controls? For example on iMac, one can change its mouse and scroll sensitivity. Can enabling larger Mouse Pointer, slowing down its "motion / user controls" be done within the IPad device as well??? thanks.
