Augmenting image plane AR 3D interactions for wearable computers


ABSTRACT This paper presents a set of large object manipulation techniques implemented in a wearable augmented reality computer system that are optimised for the outdoor setting. These techniques supplement the current image plane approach, to provide a comprehensive solution to 3D object manipulation in an augmented reality outdoor environment. The three extended manipulation techniques, Revolve, Xscale, and Ground plane translation, are focused on using what we determined to be the best coordinate system for object rotation, scaling and translation. This paper goes on to present the generalised plane technique for the constrained translation of graphical objects on arbitrary planes to enable more complex translation operations. The paper presents the techniques from both the user interface and software development perspectives. .

    ABSTRACT: The use of 3D imaging techniques has been early adopted in the footwear industry. In particular, 3D imaging could be used to aid commerce and improve the quality and sales of shoes. Footwear customization is an added value aimed not only to improve product quality, but also consumer comfort. Moreover, customisation implies a new business model that avoids the competition of mass production coming from new manufacturers settled mainly in Asian countries. However, footwear customisation implies a significant effort at different levels. In manufacturing, rapid and virtual prototyping is required; indeed the prototype is intended to become the final product. The whole design procedure must be validated using exclusively virtual techniques to ensure the feasibility of this process, since physical prototypes should be avoided. With regard to commerce, it would be desirable for the consumer to choose any model of shoes from a large 3D database and be able to try them on looking at a magic mirror. This would probably reduce costs and increase sales, since shops would not require storing every shoe model and the process of trying several models on would be easier and faster for the consumer. In this paper, new advances in 3D techniques coming from experience in cinema, TV and games are successfully applied to footwear. Firstly, the characteristics of a high-quality stereoscopic vision system for footwear are presented. Secondly, a system for the interaction with virtual footwear models based on 3D gloves is detailed. Finally, an augmented reality system (magic mirror) is presented, which is implemented with low-cost computational elements that allow a hypothetical customer to check in real time the goodness of a given virtual footwear model from an aesthetical point of view.
