- ARK multi-userPublication . Pereira, Pedro; Matos, Nuno; Grave, Luís; Marcos, AdéritoThis paper presents a monitor-based prototype for the visualisation and interaction of an Augmented Reality (AR) system, which recently developed at CCG and demonstrated during the SIACG2002 conference held in Guimarães, Portugal. ARK – Augmented Reality Kiosk - is a set-up based on the prototypes developed in the European Virtual Showcases project to which direct interaction has been added. A normal monitor and a half-silvered mirror constitute the usual set-up for the kiosk. By integrating a half-silvered mirror and a black virtual hand, the CCG solution solves the occlusion problem that normally occurs when a user interacts with a virtual environment displayed by a monitor or other projection system. Conceived with limited monetary resources this portable solution can be deployed in different application contexts as, for instance, culture heritage. This paper presents an extension of the solution to a multi-user platform for a Portuguese museum.
- VGLib2D: class library for the 2D graphic visualisation of large volumes of dataPublication . Gameiro, Sofia; Almeida, Luís; Marcos, AdéritoThis article presents the implementation of a class library in C# language, which uses the recent .Net technologies, aimed at the creation of documents or images in Scalable Vector Graphics (SVG) format, for the representation, visualisation and printing of large volumes of two-dimensional (2D) data. The goal is to take advantage of SVG for applications implementation effects that, for instance, are Web based and where the graphical representation of large volumes of data, both dynamically and in real time, is necessary, along with its immediate availability for the purposes of visualisation, printing and downloading.
- Tutoring adults online @dulinePublication . Morgado, Lina; Pereira, Alda; Miranda, Rosa; Nurmela, SatuEsta comunicação visa apresentar o modelo de um curso concebido e implementado no âmbito de uma cooperação internacional que teve como objectivo central a concepção e desenvolvimento do curso Tutoria Online.
