- Tele-media-art: feasibility tests of web-based dance education for the blind using kinect and sound synthesis of motionPublication . Dias, José Rodrigues; Penha, Rui; Morgado, Leonel; Veiga, Pedro Alves da; Carvalho, Elizabeth; Marcos, AdéritoTele-media-art is a web-based asynchronous e-learning platform, enabling blind students to have dance and theatre classes remotely, using low-cost motion tracking technology feasible for home use. Teachers and students submit dance recordings augmented with sound synthesis of their motions. Sound synthesis is generated by processing Kinect motion capture data, enabling blind students to compare the audio feedback of their motions with the audio generated by the teacher’s motions. To study the feasibility of this approach, the authors present data on early testing of the prototype, performed with blindfolded users.
- Virtual tutor: a case of study in University AbertaPublication . Carvalho, Elizabeth; Marcos, AdéritoThe project VIRTUAL TUTORING – the virtual tutor as learning mediating artifact in online university education, is an ongoing project, with the main goal of analyzing the pedagogic impact of an anthropomorphic user interface on a typical distance learning environment targeted to support online higher education. It implies the development of 3D rigged avatars that should perform typical online tutor activities. The virtual tutor should mimic a human tutor, being a kind of emphatic interface between the student and the course module in Moodle. But more than this, the virtual tutor should give support in the learning process of the student, working as much as a guide inside the contents offered by the e-learning course. This paper gives an overview of the project present development status.
- Tele-media-art: web-based inclusive teaching of body expressionPublication . Carvalho, Elizabeth; Marcos, AdéritoThe Tele-Media-Art project aims to promote the improvement of the online distance learning and artistic teaching process applied in the teaching of two test scenarios, doctorate in digital art-media and the lifelong learning course ”the experience of diversity” by exploiting multimodal telepresence facilities encompassing the diversified visual, auditory and sensory channels, as well as rich forms of gestural / body interaction. To this end, a telepresence system was developed to be installed at Palácio Ceia, in Lisbon, Portugal, headquarters of the Portuguese Open University, from which methodologies of artistic teaching in mixed regime - face-to-face and online distance - that are inclusive to blind and partially sighted students. This system has already been tested against a group of subjects, including blind people. Although positive results were achieved, more development and further tests will be carried in the future

- Virtual tutoringPublication . Marcos, Adérito; Cláudio, Ana Paula; Martinho, Carlos; Barros, Daniela Melaré Vieira; Carvalho, Elizabeth; Carmo, Maria Beatriz; Seixas, SóniaThe project VIRTUAL TUTORING – the virtual tutor as learning mediating artifact in online university education, is an ongoing project, with the main goal of analyzing the pedagogic impact of an anthropomorphic user interface on a typical distance learning environment targeted to support online higher education. This demands the creation of animated avatars for virtual tutors, able to display intelligent behaviour while interacting with the students. A Virtual Tutor should be analogous to a real human one, being able to proactively understand, solve and intervene in different student learning situations. This paper gives an overview of the project present development status.
- A prototype for cartographic human body analysisPublication . Carvalho, Elizabeth; Marcos, Adérito; Santos, Maribel Yasmina; Espregueira-Mendes, JoãoIt is proposed a cartographic-oriented model to visualize and analyze medical data relative to the human body. A prototype implementation has proved the viability and long-term promise of this approach in two case studies.
- Using a cartographic model to assist medical diagnosesPublication . Carvalho, Elizabeth; Marcos, Adérito; Santos, Maribel Yasmina; Espregueira-Mendes, João; Pereira, Rogério B.Objective: The main goal of the CHUB (cartographic human body) model is to introduce a cartographic approach that can assist in the analysis, visualization and diagnosis of medical images and related data. Method: A cartographic model is proposed as a reference framework for developing computer systems and applications. This model accommodates subtle spatial features of these data that may facilitate diagnosis. Medical images and related data are structured into different “human-referenced” information layers. Algebraic map operations are used to combine these layers and achieve greater insights into the information content. Results: Two case studies were considered to evaluate and validate the model: hydrokinetic therapy and the diagnosis of knee osteoarthritis. A prototype based on the CHUB model was implemented, and two different approaches were used to test and evaluate it. Full acceptance of the model was achieved by clinicians who used the CHUB system.
- Os avatares Maria e João: tutores virtuais na plataforma e-learning da Universidade AbertaPublication . Marcos, Adérito; Carvalho, Elizabeth; Martinho, Carlos; Cláudio, Ana Paula; Carmo, Maria Beatriz; Rocio, VitorEste artigo apresenta reflexões seminais acerca da utilização de tutores virtuais no sistema de e-learning da Universidade Aberta. O tutor virtual é uma analogia do tutor humano, adota uma interface antropomórfica com características emocionais, comumente denominado de avatar, que integra inteligência artificial e pode constituir uma abordagem interessante, tanto para o professor como para os estudantes, se se perspetivar o futuro dos ambientes típicos de ensino e educação a distância online e em rede e a crescente massificação da individualização do acompanhamento do estudante. Embora atraente de muitas formas, especialmente quando se leva em linha de conta a redução da carga da interação e do apoio que um professor (humano) deve fornecer nesses ambientes, várias questões se colocam visando a plena e efetiva integração de avatares como artefactos de mediação da tutoria virtual. Este artigo fornece um conjunto de perspetivas iniciais sobre este desafio, introduzindo o estado da arte no campo, enquanto apresenta alguns desenvolvimentos recentes e em experimentação na Universidade Aberta pela instanciação de dois avatares – a Maria e o João.
- Enhancement of Russian creative education: new post-graduation programme in digital art practicePublication . Marcos, Adérito; Amílcar, Martins; Saldanha, Ângela; Araújo, António; Carvalho, Elizabeth; Bidarra, José; Coelho, José; Shirley, Paulo; Veiga, Pedro Alves da; Cardoso, Vitor; Pais, Carlos CastilhoIn Project TEMPUS “Enhancement of Russian Creative Education: new Master Programme in Digital Arts in line with EU standards” (2014-2016) the Russian students had the opportunity to study in EU Universities for one semester. The Universidade Aberta, in Portugal, didn’t have a master degree in Digital Arts so a pilot programme had to be created: a new postgraduation in Digital Art Practice. This new curriculum, using blearning (based on online and face to face activities) with transdisciplinary methods, aims a practice oriented training on digital art. It started with a deep understanding of Lisbon, the relationship between people, cultural and artistic spaces and their environments. This knowledge inspired the students to produce and to create an artistic artefact presented in exhibition to an audience. With this postgraduation new possibilities started for reflection about global challenges for education in the millennium.
- Ensinar programação em ambientes e-learning: preocupações e propostas no âmbito do modelo pedagógico virtual da Universidade Aberta de PortugalPublication . Mucheroni, Marcos; Carvalho, Elizabeth; Marcos, AdéritoO ensino e aprendizagem da programação de computadores em ambiente e-learning constitui uma área que tem vindo a atrair um interesse crescente tanto por parte das universidades de ensino em rede como pelos investigadores do e-learning. Aprender a programar computadores requer o desenvolvimento de raciocínio lógico da parte do estudante, enquanto aprende a dominar as potencialidades de uma determinada linguagem de programação, a construir estruturas de dados e a desenvolver uma estratégia de resolução de problemas pela sua divisão e modularização em problemas mais simples de mais fácil conquista. Adicionalmente importa que o estudante desenvolva competências de trabalho em grupo, de estudo individual com elevados níveis de concentração para realizar trabalho de revisão e depuração de código fonte. O ensino on-line de programação de computadores é constituído por estes aspetos, exigindo um elevado grau de interação entre estudantes e destes com o professor. Neste artigo, apresentamos um conjunto de reflexões e propostas concretas de estratégias de implementação do ensino e aprendizagem da programação de computadores, de nível universitário, explorando o método de “design” de instruções como uma abordagem do diálogo, uma adaptação da taxonomia de Bloom, com base na experiência e no modelo pedagógico virtual da Universidade Aberta de Portugal.
