“…Both a high level of object-presence and the ability to touch the PA model are important for many of these applications. Indeed, the size perception task in this experiment (not reported in this paper) found that touching a PA model increases how accurately a user perceives it [22]. However, these results suggest that touching this type of PA model reduces object-presence.…”

A Projection Augmented Model (PA model) is a type of projection based haptic Augmented Reality display. It consists of a real physical model, onto which a computer image is projected to create a realistic looking object. Users can physically touch the surface of a PA model with their bare hands, which has clear experiential value for the types of applications for which they are being developed. However, the majority of PA models are front-projected and do not provide haptic feedback for material properties (e.g. temperature and physical texture), which suggests a user's sense of objectpresence will be reduced when this type of PA model is touched. (Object-presence measures the subjective feeling that the object the PA model represents exists in a person's environment, as opposed to a white physical model and a projected computer image.) Alternatively, if people consider PA models to be essentially computer generated objects (i.e. it is the projected image that gives the 'dummy' physical model meaning), then the act of being able to touch computer generated information may increase object-presence. The empirical investigation reported in this paper found that object-presence was lower when this type of PA model was touched. The implications these results have for both PA models and other types of displays, are discussed.

Tangible 3D tabletops are a novel type of interface, which combines tangible tabletop interaction with 3D projection in such a way that the tangible objects can be augmented with visual content corresponding to their physical shapes, positions and orientations on the tabletop. We present a specific tangible 3D tabletop installation, Projected Play, which was developed for and deployed at LEGO World, a four-day event at which visitors immerse themselves in the world of LEGO. The use of Projected Play was documented through observations, interviews and video recordings. We propose an analytical approach to understanding the perception and use of this type of installation building upon existing research into interaction in public spaces. We apply this approach to analyse how people interacted with and experienced the installation. The focal points of the analytical approach include social, cultural and physical aspects of experience, interaction patterns and forms of engagement. Moreover, we critically discuss the potentials and limitations of both the analytical approach and the installation.
