Resumo
Pesquisa para verificar o nível de usabilidade de composições tipográficas de textos com quatro fontes ( Rockwell, Garamond, Franklin Gothic e Bodoni ) na tarefa de leitura em suporte de leitura em papel branco e em tela digital ( LCD ). Efetuou-se tal verificação por meio de três parâmetros: eficácia ( teste de assimilação do texto ), eficiência ( tempo de leitura ) e satisfação ( opinião do leitor ), os quais possibilitaram determinar o nível de usabilidade da interface de um objeto dentro de uma escala com intervalo de níveis (Ótimo, Bom, Satisfatório e Péssimo ). Os dados dos grupos amostrais obtidos foram tratados por estatística inferencial, sendo dois grupos para cada uma das fontes tipográficas as quais foram lidas em cada um dos suportes. O texto padronizado utilizado faz parte de um conjunto de textos utilizados na Oftalmologia para testes de velocidade de leitura. Os resultados obtidos permitiram verificar que não há influência significativa no nível de usabilidade de leitura de um texto padronizado composto com diferentes fontes tipográficas. O tempo médio de leitura da amostra foi 51,87 ( ± 16,51 ) segundos, em uma escala que variou de 1-106,13 segundos. O número de acertos médios nas cinco questões do teste de interpretação foi 2,90 ( ± 1,64 ) numa escala de 0-5 acertos. A taxa média de satisfação dos leitores em relação as fontes tipográficas verificadas foi 66,24 % ( ± 20,94 ), numa escala de 0-100%. O método utilizado para se calcular a taxa de usabilidade das fontes foi a média aritmética entre as taxas percentuais dos três parâmetros já descritos. As taxas de usabilidade foram distribuídas na escala de usabilidade de quatro níveis onde se verificou que todas fontes apresentaram uma taxa de usabilidade próxima a 60 %, equivalendo, portanto, a um bom nível de usabilidade. Concluiu-se que os traços comuns das letras e a equiparação da altura-x pode equilibrar o nível de usabilidade de diferentes fontes tipográficas na leitura tarefa.
Research to verify the usability level of typographic compositions of texts with four fonts (Rockwell, Garamond, Franklin Gothic and Bodoni) on the task of reading, as in white paper media reading as in digital display reading (LCD). Such verification was performed by three parameters: effectiveness (interpretation test), efficiency (reading time) and satisfaction (reader's opinion), which had enabled to determine the usability level of the interface of an object within a scale range of levels (Excellent, Good, Satisfying and Poorly). The data sample groups obtained were processed by inferential statistical, being two groups for each of the typographical fonts, which had been read in each media. The standardized text is part of a set of texts used in Ophthalmology to measure the reading speed. The results obtained allowed to verify that there is no influence on reading usability of a standardized text composed with different typographical fonts. The average reading time of the subjects was 51.87 (± 16.51) seconds on a scale ranging from 1 to 106.13 seconds. The average hits on the five questions from the interpretation test was 2.90 (± 1.64) on a scale 0-5 hits. The average rate of satisfaction of the readers about the typographic fonts checked was 66.24% (± 20.94), on a scale of 0-100%. The average rate of the readers satisfaction regarding the verified typefaces was 66.24% (± 20.94), on a scale of 0-100% of the three parameters already mentioned. The usability rates were distributed in a four-level usability scale, where it was found that all the fonts showed a close usability rate near to 60%, indicating a good level of usability. It concluded that the commonality between letterforms and equalization of x-height balances the level of usability among different fonts in task reading.
