Abstract:
1. A user interface system for inputting information, comprising: a touch screen; a tactile key mechanism placed adjacent to a first touch screen actuator within said touch screen, the key mechanism including a housing and a key moveable relative to the housing having a tactile surface, the key mechanism including components responding to a keypress of the key by acting on the first touch screen actuator so as to cause detection of a touch by the first touch screen actuator, the key mechanism further including components responding to a keypress of the key resulting in detection of a touch by the first touch screen actuator so as to produce a tactile feedback to a user indicating that the keypress has been sufficient to produce a successful detection of a touch by the first touch screen actuator; and a choice-driven interface application program controlling displays on the touch screen of a specific sequence of overlays based on choices entered by an operator.
