Abstract
Techniques for increasing accessibility of touch-screen devices are disclosed. In one aspect, container regions on a touch-sensitive user interface of a touch screen device are defined. A touch event corresponding to a location on the user interface is received, and it is determined that the location corresponds to a particular container region. When another touch event is received, content is determined according to a context of the particular container region. The content is then presented. In another aspect, data specifying locations of user interface items on a user interface is received. The data is modified to enlarge an area for a particular item. A touch input event corresponding to a particular location on the user interface is received. It is determined that the location is within the enlarged area for the item, and input is provided to an application indicating that the item was selected.
