Linguagens computacionais como interfaces: um estudo com nested context language

This paper presents an empirical study about the Nested Context Language (NCL), which is a language developed to create multimedia documents and Interactive Digital TV (IDTV) applications for the Brazilian system. The goal was to obtain indicators of NCL usability in the generation of content for IDTV, since this language plays the role of interface language for users. Through data collected on forms filled by 220 students from various classes of training courses conducted in some states of Brazil and later analysis by a mix of qualitative and quantitative methods, some aspects were found where the NCL profile can and should be improved in order to ease the activities of content creators for IDTV, who have a heterogeneous profile and are not necessarily familiar with computer programming.
