摘要
A user interface, typically to an irrigation controller, prompts user responses by continuously autoscrolling questions. The questions are hierarchally organized, preferably in a hierarchal tree having approximately three to six questions on each hierarchal level between root and leaves. All command and data input may be done with only an OK/YES pushbutton switch, switches. Each OK/YES user response affirms the premise fo a currently-displayed question, and advances the autoscrolled questioning to a related branch upon a next hierarchal level. The NO pushbutton is never required to advance the questioning which is always autoscrolled, but instead serves, while depressed, to accelerate the autoscrolling of successive questions. A HELP response invokes context- sensitive help messages. A STOP response causes reversion in the hierarchy of questioning toward the root level, but does not stop the autoscrolling of questions.
