“…Finally, in the work of de Jesus Lima Gomes et al [7], an interface using barcode on paper was designed to assist the interaction with a distance learning system using the television. Systems like this, if restricted to the traditional remote control, have the advantage of reaching a wider audience, but offer a more complex interaction.…”

“…Some of them try to develop better remote controls [22,2,6,13]. Others propose different mechanisms not yet explored, as accelerometers [3], remote controls with barcodes reader [7], interactive applications that reproduce gestures [21], approaches that combine speech and remote control [5], or intelligent prediction mechanisms of text entry from the remote control [12], for instances.…”

“…The possibility of inserting new lines using the "OK" key, offered when this state is activated, is not worth the amount of errors generated. (7) The interface of the speech mode is not clear enough and causes a lot of problems. The use of two columns of commands in the Dictation state makes the user associate the right column with the Commands state.…”

The development of interactive digital TV applications is hindered by the user-interaction options allowed when traditional remote controls are used. In this work, we describe the model of a software component that allows text entry in interactive TV applications based on an interface with multiple input modes -the component offers a virtual keyboard mode, a cell keypad mode, and a speech mode. We discuss our considerations with respect to the design, development and evaluation of a prototype corresponding to our model, built according to the user-centered design methodology. After conducting a research on existing text input methods in television systems, we interviewed four experts in the interactive TV domain. We also applied 153 questionnaires to TV users, with the aim of gathering a user profile of users who make use of text entry mechanisms. During the development of the prototype, we conducted usability tests using the think aloud protocol, and usability inspections using the heuristic evaluation and cognitive walkthrough techniques. The evaluations allowed the detection of both, a number of problems and of several improvement opportunities; at the same time that they highlighted the importance of using complementary text input modes in order to satisfy the needs of different users. Overall, the evaluation results suggest that the proposed approach provides a satisfactory level of usability by overcoming the limitations of text input in the context of user-interaction with interactive TV applications.

Saído da noite que me cobre, negro como "O"poço de ponta a ponta, agradeço aos deuses que possam existir pela minha alma inconquistável. Nas cruéis garras das circunstâncias eu não recuei, nem gritei. Sob os golpes do acaso minha cabeça sangra, mas não se abaixa. Além deste lugar de ira e lágrimas assoma o horror das sombras, e, contudo, a ameaça dos anos encontra-me e continuará me encontrar sem medo. Não importa quão estreito o portão, quão cheia de castigos minha lista, eu sou o mestre do meu destino: eu sou o capitão da minha alma Invictus (em tradução livre), de William Hernest Henley vi Agradecimentos À minha mãe, Magali, pela presença e ajuda, sempre incondicionais. À minha irmã, Juliana, pelo apoio constante, mesmo nas horas mais difíceis. À minha irmã Janaina, meu cunhado Devair pela presença, ajuda e confiança que depositaram em mim. Ao meu sobrinho Matheus, por tornar a vida mais fácil apenas com uma risada. Ao meu Pai, José Augusto, pelo voto de confiança, pela paciência e pela amizade. Aos colegas do Laboratório Intermidia, pelas piadas que aguentaram sem reclamar e pelo convívio. Aos amigos de infância, Yuri, Gabriel e Guilherme. Outros nem tanto de infância mas tão importantes quanto:
