Paper&Pencil Augmented Reality Game

paper_and_pencil A game able to dramatize an interactive narrative in augmented reality over a conventional sheet of paper. The system allows the player to freely interact with virtual characters by sketching objects on the paper. The player can indirectly affect the characters’ decisions, even to the point of radically subverting the storyline.People: Edirlei Lima, Bruno Feijó, Antonio Furtado, Cesar Pozzer, Angelo Ciarlini, Simone BarbosaPublications:

Pervasive Mobile Games

pervasive_gamesPervasiveness can be recognized in a game by its boundaries that expand every time it is played, from the virtual (or fictional) world to the real world. Pervasive games are a new form of digital entertainment that has evolved in different forms, such as alternate reality games, transmedia games, and crossmedia games. Sensor technologies, networking capabilities, augmented reality systems, computer vision technology, the internet, and, especially, mobile devices have been responsible for the rapid evolution of this new form of digital product. We bear in mind that mobile devices are currently the main driver for fulfilling the promises of pervasive game playing. Our investigations and experiments on this class of games have the objective of to enhance the insight into pervasiveness and to reveal important guidelines for game designers and programmers.

Interactive Objects in High-Definition Video

A method for reainteractive storyl-time object tracking in high-definition (HD) videos is investigated. There are few works in the literature considering HD and multiple objects in real time. Good solutions for this problem are of paramount importance when we have interactive hot spots and real-time compositing processes in interactive digital television.

The Interactive Comics Project

Comics are a unique and clInteractive_comicsassical form of storytelling. The advent of interactive narratives brings the possibility of interaction to the traditional comic books. In this project we search for an interactive comics system that is capable of generating dynamic interactive narratives in the format of comic books. The system should allow users to interact with certain objects and to observe the consequences of their actions in the unfolding story.

Video-Based Interactive Storytelling

Usually, interactive storytellinvideo_based_ISg systems adopt computer graphics to represent the virtual story worlds, which facilitates the dynamic generation of visual content. Although animation is a powerful storytelling medium, live-action films are still attracting more attention from the general public. In addition, despite the recent progress in graphics rendering and the wide-scale acceptance of 3D animation in films, the visual quality of video is still far superior to that of real-time generated computer graphics. In this project, we propose a new approach to create more engaging interactive narratives, denominated “Video-Based Interactive Storytelling”, where characters and virtual environments are replaced by real actors and settings, without losing the logical structure of the narrative.

Educational Models for Technical Secondary Schools

This project searches for neNAVE_productsw models of school where a research center and a production center live in a symbiotic manner. Structural changes in the traditional school model must be identified. These changes are imperative if we are to keep that subsystem of society up with the contemporary world. This project investigates particularities of Brazilian technical secondary schools and focusses on programming learning, computational thinking, and multimedia languages that should be present in educational processes.

Main PartnerOi Futuro through the project NAVE (Nucleus of Advanced Education) – NAVE is also a Microsoft Innovative Mentor School (2012) and a Microsoft World Tour School (see CE José Leite Lopes – NAVE Rio).
