This dissertation was a two-phase effort. Phase I investigated the physical image quality of 16 mesh, etched, and quarterwave antireflection filters for varying levels of filter transmissivity. Three levels of ambient lighting and two levels of monochrome CRT resolution were combined factorially with the filters. In addition, user measures of readability, legibility, and perceived image quality were obtained for these same filter and environmental conditions. Quantitative models were developed to predict the performance and subjective data based on signal and noise measures derived from the physical measurements. Phase II examined the effects of a wide range of filter transmissions and diffuse illuminance on measured image quality and the same user measures as in Phase I. Phase I showed that while none of the glare filters yielded improved readability or legibility over a baseline condition, the etched and low transmission filters were notable for their degradation of human performance. Mesh and quarterwave filters were found to improve perceived image quality when a specular glare source was present. Modeling was minimally successful for the reading and legibility tasks, but yielded good fit models for perceived image quality. Phase II showed that when even extreme losses in display contrast occurred, users were capable of good reading and legibility performance. Perceived image quality was inversely related to illuminance level. Prediction of performance by image quality metrics was generally not too successful. It was concluded that in office-type environments, mesh or quarterwave filters can be used to improve perceived image quality when specular glare sources are present, but that no anti-glare filters yielded enhanced short-term readability or legibility over a baseline. Etched filters were not recommended. Measures of physical image quality proved to be good predictors of perceived image quality, but not of timed measures of readability or legibility. Under moderate lighting conditions, monochrome CRTs should be fitted with fairly high transmission filters as it was found the contrast enhancement offered by low transmission filters had negligible effects on performance. Finally, consistent and repeatable findings of degraded legibility for high luminance contrast levels (low illuminance) generated questions as to the existing standards regarding maximum contrast requirements for CRT use. / Ph.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) / Pesquisas do Instituto Nacional de Estudos e Pesquisas Educacionais (INEP), Censo da Educação Superior, Teses e Dissertações, apontam que os cursos de graduação na área de Computação são os com menor número de mulheres matriculadas. Assim, para compreender quais os fatores para esta disparidade, foram propostas, nesta pesquisa, três oficinas com estudantes e egressas de cursos da área de computação de uma universidade federal: a primeira foi uma atividade presencial com estudantes da área de Computação para entender as percepções e memórias destas pessoas; a segunda também foi uma atividade presencial com este mesmo intuito, porém, com egressas de Bacharelado em Sistemas de Informação (BSI) e Engenharia de Computação (EC); e a terceira, um espaço virtual para promover a participação e discussão sobre as memórias das egressas. Para essas três oficinas, utilizou-se uma prática de Design Participativo (DP), a Oficina de Futuro. O Design Participativo proporcionou que cada uma das atividades tivesse o desenvolvimento conduzido de forma diferente, pois a proposta de DP permitiu que as práticas fossem organizadas colaborativamente pelos participantes, o que difere dos dados obtidos por questionários, por exemplo. Os resultados destas aproximações trazem as percepções e memórias de estudantes e egressas sobre a participação de mulheres na área de Computação. Estes resultados encaminham que cabe à sociedade e à comunidade acadêmica promover discussões para a implementação de política de cotas para gêneros, promover mudanças, apontando para a igualdade de gênero, no ambiente escolar, no mercado de trabalho e nos papéis sociais. / In researches of National Institute for Educational Studies and Research (NIES), Higher Education Census, Theses and Dissertation, it was observed that undergraduate courses in Computing are those with fewer women enrolled. Accessing such information identifies that quantify data about women participation in Computing area is insufficient. Thus, to comprehend which factors to this disparity has proposed three workshops: first face-to-face workshop with students of Computing area; second also a workshop, however, with recent grads of Bachelor of Information Systems and Computer Engineering; and third a virtual space for collaboration on topics that involve the women participation in Computing, remote mode, in corais.org plataform, three workshops were with students and recent grads from the same Institution – Federal Technological University of Paraná – in Curitiba. The three workshops used Participatory Design (PD) practice - future workshop, however in each of them the development was different, because (PD) allowed that participants organized the approach collaboratively. The results bring perceptions and memories of students and recent grad about women participation in Computing, and these results point out that is up to society and to University, to promote discussions to implementing genre quotas, changes since childhood, at school, and the participation of parents and all the society; it is necessary to point to gender equality; labor market; opportunities; destruction of gender categories and the development of public policy for equity.
