概要

• Windows that are overlaid only by an AccessibilityService for interception of user interactions without changing the windows an accessibility service can introspect.
• In particular, an accessibility service can introspect only windows that a sighted user can interact with which is they can touch these windows or can type into these windows. For example, if there is a full screen accessibility overlay that is touchable, the windows below it will be introspectable by an accessibility service regardless they are covered by a touchable window.
