Abstract


One of the main features of television as a means of mass communication is the ease of handling of the device. With the improvement of communication and information technologies, an increasing range of options is offered to viewers who need to adapt to graphical interfaces, buttons and menus. The pay TV channels now offer a variety of options for local interactivity, such as choice of programming by genre or actors, however, these channels are watched by only part of the population, which in their social condition, is more familiar with the technology. Digital TV comes with the possibility of offering interactivity also in open channels, a fact which requires the design of self-explanatory interfaces to facilitate usability and promote the democratization of access to information and knowledge.
