Integrating different mental models and the corresponding interaction techniques for navigation and object manipulation tasks is a topic of concern for providing user interfaces for the wide variety of potential users.

Here, specifically the toy airplane and the window frame contradict each other, leaving the issue at which postural angle of the hand-held device the mental model of the users changes.
