Uma interface t-commerce com o auxilio de uma técnica de visualização da informação para o middleware brasileiro de iDTV

Abstract

With the progressive growth of e-commerce in Brazilian scenario and the spreading of the digital transmissions on TV, grows up the demand for interactive applications supporting activities, such as to choose and buy products. In this context, this work’s main hypothesis verify if the use of a Information Visualization (InfoVis) technique in the t-commerce scenario, would facilitate the perception and would allow the views to take better decisions at purchase. To ease the decision process while choosing products by the Interactive Digital TV (iDTV), this work developed a t-commerce interface based on the Brazilian digital TV middleware – Ginga, we used the Treemap InfoVis technique, in order to improve the viewer interface with more organized and coherent information to enlarge their understanding of the data. As a mean to validate the hypotheses and assess the t-commerce interface, a usability test was done, and to evaluate the volume of subjective workload during the tests, the NASA-TLX (NASA - Task Load Index) were used. Therefore, we concluded that the application of a InfoVis technique in the t-commerce scenario proved to be effective.
