Abstract

Achieving the ubiquity of in-place content authoring is essential to the next generation of mobile augmented reality browsers. In-place authoring is expected to be intuitive for end users and lightweight for common smart phones. We propose a solution for in-place world labeling that makes use of the smart phones' camera parameters, its built-in sensors and a little help from the user(s). The extracted data is used to calculate the 3D location of a point of interest in the user's scene and validate its presence within the cameras viewing pyramid. The proposed approach allows for single and multiple authors for the same POI which gives much promise for supporting social and collaborative authoring. We describe multiple techniques for calculating the POI location to accommodate for the different interaction scenarios with the users.
