Abstract: We propose a filtering system for occlusion-aware contours. Given a point of view, we use the silhouette of a 3D shape from that point of view, its medial axis and a map of the occluded areas. Our filter is able to select the points of the medial axis which are projections of the curve-skeleton of the 3D shape, discarding all the points affected by occlusions. Our algorithm is easy to implement and works in real time. It can be plugged as is into existing methods for curve-skeleton extraction from 2D images; it can be used to robustly rank silhouettes according to how much they are representative of the 3D shape that generated them and can also be used for shape recognition from images or video sequences.

Abstract: We present here a proof-of-concept of an integrated system for enhancing the shopping experience in a shoes’ shop. The system uses two modules: (i) one internal to the shop using an interactive totem; (ii) one external to the shop based on the customer’s mobile device and the interactive external shop surface. We describe the technical architecture of the two modules and two different scenarios of the user experience.
Abstract: In this paper we introduce the Virtuoso project, which aims at creating a seamless interactive support for fitness and wellness activities in touristic resorts. The overall idea is to evaluate the current physical state of the user through a technology-enhanced mirror. We describe thes tate of the art technologies for building a smart mirror prototype. In addition, we compare different parameters for evaluating the user’s physical state, considering the user’s impact, the contact requirements and their cost. Finally we depict the planned setup and evaluation setting for the Virtuoso project.
Abstract: WoBo (World in a Box) aims to provide a new experience for travellers, allowing them to visit distant or hardly reachable places through the exploitation of consumer cameras and a head mounted display. The experience consists in watching a 360-degrees video with 3D audio in a dedicated cabin. The user can select videos shot in different places, which have been created with six consumer cameras. We describe the proposed experience, the hardware and the software used for a first prototype.
