How to interact with reality meadiated through AR? Specially in the field of cultural heritage. The following interaction techniques follow the rules of recuded and menu-less interaction with reality. Those are parts of my master thesis I recently published.
Emphasize
More a princple than an interaction technique is to use AR to highlight/emphasize reality or reduce it. In this case to uncover architecuteal elements that do not come straight to the eyes.
Pointing metaphor
A real interaction principle: why use menues or buttons, if reality can expose itself? Either by (image) recognition or as in this case via a pointing metaphor, where interaction is basically motion/movement controlled and triggered by a crosshair poiting towards a target. It’s pretty much like gazing at a point of interest.
Approximation
Another principle, where the densitiy of information increases, once a user comes closer to an object of interest. Approximation controls information in this case. Technically, this could involve e.g. to switch from an sensor-based tracking (see Wiktide, Junaio, Layar …) to more sophisticated computer vision tracking.
Michael and others are working in the area of interaction as well.
