Bell, Blaine A., Hollerer, Tobias and Feiner, Steven K. (2002): An annotated situation-awareness aid for augmented reality. In: Beaudouin-Lafon, Michel (ed.) Proceedings of the 15th annual ACM symposium on User interface software and technology October 27-30, 2002, Paris, France. pp. 213-216. Available online

We present a situation-awareness aid for augmented reality systems based on an annotated "world in miniature." Our aid is designed to provide users with an overview of their environment that allows them to select and inquire about the objects that it contains. Two key capabilities are discussed that are intended to address the needs of mobile users. The aid's position, scale, and orientation are controlled by a novel approach that allows the user to inspect the aid without the need for manual interaction. As the user alternates their attention between the physical world and virtual aid, popup annotations associated with selected objects can move freely between the objects' representations in the two models.

Bell, Blaine A., Feiner, Steven K. and Hollerer, Tobias (2001): View management for virtual and augmented reality. In: Marks, Joe and Mynatt, Elizabeth D. (eds.) Proceedings of the 14th annual ACM symposium on User interface software and technology November 11 - 14, 2001, Orlando, Florida. pp. 101-110. Available online

We describe a view-management component for interactive 3D user interfaces. By view management, we mean maintaining visual constraints on the projections of objects on the view plane, such as locating related objects near each other, or preventing objects from occluding each other. Our view-management component accomplishes this by modifying selected object properties, including position, size, and transparency, which are tagged to indicate their constraints. For example, some objects may have geometric properties that are determined entirely by a physical simulation and which cannot be modified, while other objects may be annotations whose position and size are flexible. We introduce algorithms that use upright rectangular extents to represent on the view plane a dynamic and efficient approximation of the occupied space containing the projections of visible portions of 3D objects, as well as the unoccupied space in which objects can be placed to avoid occlusion. Layout decisions from previous frames are taken into account to reduce visual discontinuities. We present augmented reality and virtual reality examples to which we have applied our approach, including a dynamically labeled and annotated environment.
