With the increasing sophistication of virtual learning environments, online learning has at its disposal resources that provide an education more effectively. Importantly say, the collaborative activities can be enhanced in virtual learning environments, since the elements of social awareness are willing and will allow participants to share knowledge and experiences. The present work aims to establish requirements related to the phenomena of social awareness and collaboration in Amadeus LMS. This research was an exploratory qualitative study. The methodological approach applied in this work was the interaction with the environment, questionnaires, conducting focus group, video recording and observation. The participants are students of final year coach IFPE - Campus Belo Jardim. Needs were identified and the results indicate that the functionality of the elements of social awareness of Amadeus LMS needs to be complemented, and that other elements must be integrated. The results of this research were prototyped for Amadeus LMS.

Word-of-mouth in the Internet is rapidly increasing, but the dissemination of this information is sometime difficult to interpret. This paper presents a visualisation platform (BrandMap). It was used to structure data of brand association distribution in the blogosphere as a case study that analyses the word-of-mouth of two smartphone brands in Brazil. BrandMap is a prototype that was developed based on extensive research about word-of-mouth in the blogosphere and how to visualize brands monitoring. BrandMap uses a novel approach for information visualization of complex data. The result was the evaluation of BrandMap analyses that compared the user's perception about the advantages and disadvantages of two brands in social networks.

Este trabalho descreve a análise de requisitos e concepção de artefato social para regulação de dificuldades de aprendizagem de conteúdos abordados no ensino médio presencial com tecnologia. A concepção e o desenvolvimento, do artefato social para avaliação formadora, serão descritos com protótipos iterativos, a partir de cenários descritos a luz da Teoria da Atividade. Foram construídos vários protótipos de baixa fidelidade até chegar ao protótipo a ser implementado para essa pesquisa de doutorado em andamento.

Sketch-Based Interfaces are becoming a popular interaction style for many applications. The interaction style tries to recreate the experience of sketching that is similar to real paper and pencil drawings.They are being used to accomplish tasks related to geometric modeling, animation, architecture, design, music, and learning, among others. In this work we evaluate and compare two interaction approaches, Sketch and WIMP, in tasks for modeling 3D objects. We used two distinct tools: Teddy - a sketch based modeling software, and the more traditional WIMP modeling tools Maya & 3DS Max. We used quantitative and qualitative methods to identify benefits from both techniques from the users' perspective. These data will be turned into requirements for a future prototype based on the usability gains of a combination between the two approaches in study.
