A abordagem teórica inicia-se com o questionamento sobre a popularização dos computadores pessoais e a difusão da internet e seus "novos" processos communicacionais que fizeram emergir apontamentos sobre a forma de interação entre o ser humano e os sistemas comunicacionais. Também aborda os aspectos de design de interface, ao entender que este corresponde ao primeiro contado do indivíduo com a informação apresentada no site e, por essa razão, ressaltam-se as questões relacionadas à apresentação da informação visual. Para completar a relação entre tecnologia e ser humano, são apresentados dados sobre Interação Humano-Computador (HC), usabilidade e ergonomia cognitiva, e métodos de avaliação de interface, assim como também algumas definições e classificações sobre o jornal impresso e o digital. Deste modo, o estudo apresenta um análise ergonômica e de usabilidade sobre a leitura dos jornais eletrônicos a partir da comparação com os jornais impressos. Como método, adotou-se uma avaliação de percepção do usuário, a partir de um questionário impresso aplicado a um grupo de 41 sujeitos. De modo geral, os resultados indicam que nos jornais analisados há a necessidade de um maior cuidado com os aspectos da representação visual. Neste sentido, entende-se que a pesquisa colaborou com os estudos da área, pois enfatiza a necessidade de se incluir os usuários no desenvolvimento de interfaces web, assim como também em utilizar com maior critério a muldisciplinariedade do suporte e fazer com as áreas de design, usabilidade, ergonomia, tecnologia e comunicação trabalhem em congruência. / Abstract: The study deals with issues related to interface design, usability and technical evaluation of web interfaces. The theorical approach starts with the questioning of the popularity growth of personal computers and the spread of the Internet with its "new" communication processes that have emerge notes about the form of interaction between humans and communicational systems. Also covers aspects of interface design, understanding that this is the first contact of the individual with the information presented on the site and, for that reason, issues related to the presentation of visual information are emphasized. To complete the relation between technology and the human being, it presents data about Human-Computer Interaction (HCI), usability and cognitive ergonomics, and methods for interface evaluation, as well as some definitions and classifications on the paper and digital form of the news. Thus, the study presents an ergonomic and usability analysis on the reading of eletronic journal from the comparison with the printed newspaper. As a method, it was adopted an evaluation of the user perception, from a printed questionnaire applied to a group of 41 subjects. Overall, the results indicate that on the analyzed newspaper there is a need for greater care concerning the aspects of visual representation. In this sense, the study helped with the studies in the area, as it emphasizes the need to include users in development process of web interfaces, as well as to use with more discretion the support's multidisciplinarity and make the areas of design, usability, ergonomics, technology and communication to work in congruence. / Mestre

Digitalisering av gränssnitt i bilar har lett till att fler funktionerimplementeras i gränssnitten, vilket resulterat i ett ökat informationsflödetill föraren. Detta har ökat behovet av att gränssnitt designas för transparens.Då räckviddsmätare i elbilar behöver hantera stora mängder information kanbrist på transparens leda till att förare upplever räckviddsångest. Att designaräckviddsmätare som kan förmedla stora mängder information så att förareupplever räckviddsinformationen som transparent kan därmed leda tillminskad räckviddsångest hos elbilsförare. Tidigare forskning har visat attadaptiva gränssnitt kan hantera och förmedla stora mängder komplexinformation, vilket visar potential för att transparent visualiseraräckviddsinformation till en förare. En litteraturstudie har genomförts därfyra dimensioner av transparens har identifierats, samt fyra designriktlinjerför hur adaptiva räckviddsmätare kan designas. Genom en designstudieimplementerades designriktlinjerna i tre designförslag. Designriktlinjernautvärderades sedan genom att implementeras i en körsimulator för attundersöka om räckviddsinformationen upplevdes som transparent avdeltagarna. Studien resulterade i lärdomar och insikter i hurdesignriktlinjerna kan implementeras vid design av adaptivaräckviddsmätare för transparent räckviddsinformation i elbilar. / Digitalization of interfaces in cars has led to more functions beingimplemented in the interfaces which have resulted in an increased amount ofinformation to the driver. This has increased the need for interfaces to bedesigned for transparency. Because range meters need to be able to handlelarge amounts of information, a lack of transparency could lead to the driverexperiencing range anxiety. Designing range meters that can mediate largeamounts of complex information which is perceived as transparent couldreduce range anxiety among electric car drivers. Earlier research has shownthat adaptive interfaces can handle and mediate large amounts of complexinformation which shows potential for transparently visualizing rangeinformation to drivers. A literature review has been conducted where fourdimensions of transparency have been identified, as well as four designguidelines for how adaptive range meters can be designed. Through a designstudy, the guidelines were implemented in three design proposals. Theguidelines were then evaluated through the design proposals in a drivingsimulator to examine if transparency was experienced by the participants.The study resulted in insights into how the guidelines can be implementedin the design of adaptive range meters for transparent range information inelectric cars.
