- Behavioral Differences And Impact Of Lowercase And Uppercase Letters On Reading PerformancePublication . Teixeira, Ana Rita; Brito-Costa, Sónia; Ferreira Antunes, Maria Fernanda; Espada, Sílvia MariaThe aim of this work is to understand the impact of lowercase letters and uppercase letters in terms of reading. Four sessions were held in which subjects are aged from 15 to 59 years old. Of the 19 participants with a mean age of 26.52 years (SD=13.14), to understand which letters (lowercase versus uppercase) presents a shorter reading time and higher levels of calmness, considering two different complexity texts (children and scientific) in two different forms of interaction (paper reading and screen reading). Several tests were carried out to ensure the intended result in order to comprehend the influence of various visual variables because of a more precise reading process. Four variables were examined using various sensors, including the Brain Computer Interaction (BCI) device, to measure heart rate activity (HRA) and levels of brain activity (active, neutral, and calm). The number of errors, the reading time, the heart rate variability and the calmness, active and neutral levels were considered. Our findings demonstrate that depending on the type of letters (lowercase versus uppercase), and the type of text (scientific versus children's text), and the reading text presentation (paper or screen), the visual variables have a different effect on reading performance.
- O enfermeiro na prevenção da hérnia na pessoa com ostomia de eliminação intestinal :Publication . De Sousa Correia, Ricardo Filipe; Teixeira, Ana Rita; Silva, Claudia Isabel Domingos da; Ribeiro, Joana; Santos, CéliaEnquadramento: Na pessoa com ostomia de eliminação intestinal, a hérnia paraestomal é uma complicação tardia frequente com implicações na qualidade de vida. Objetivos: Descrever as intervenções de enfermagem que reduzem o risco de desenvolver hérnia paraestomal na pessoa com ostomia de eliminação intestinal. Metodologia: Trata-se de uma revisão integrativa da literatura entre janeiro de 2015 e dezembro de 2020, de acordo com a metodologia PICO, nas bases de dados Cumulative Index to Nursing and Allied Health Literature (CINAHL) e Medical Literature Analysis and Retrieval System Online (MEDLINE), acessíveis através do agregador de conteúdos científicos EBSCOhost web, dos quais cinco atenderam aos critérios de inclusão. Principais tópicos em análise: Os temas que emergiram na busca do conhecimento foram a importância da identificação dos fatores de risco, marcação do local do estoma, exercício físico, vestuário de suporte, e educação para a saúde. Conclusão: Cabe ao enfermeiro em estomaterapia advertir a pessoa com ostomia para os fatores de risco modificáveis, consciencializando-a e tornando-a parte do processo. Considera-se necessária investigação adicional quanto às estratégias que reduzem a incidência de hérnia paraestomal.
- The Influence of Line Length: A Pilot StudyPublication . Teixeira, Ana Rita; Brito-Costa, Sónia; ANTUNES DE ABREU, MARIA FERNANDA; Espada, Sílvia MariaThe aim of this work is to understand the impact of typography on humans in terms of reading. Several tests were carried out to achieve the proposed objective of understanding the influence of different visual variables to ensure a more precise reading process. Four variables were studied using various sensors, such as the Brain Computer Interaction (BCI) device, to measure brain activity (active, neutral, and calm) and heart rate activity (HRA). The reading time and the number of errors were also considered. The results show that the visual variables have a different impact considering the type of text (scientific and children’s text) as well as the reading medium (paper or screen). In addition, the results show that preferences vary according to the type of visual variables as predicted and as confirmed by the measurements taken during the reading process. However, oddly enough, the participants when questioned during the survey, their answers were not coincident by the measurement results. For this reason, this empirical study in interaction design is important as a future reference approach to the perceptibility and readability of text. On the other hand, the use of BCI and HRA parameters is not widely described in the literature. So, this paper allowed to perceive and identify the most adaptable typographic parameters both in the type of text and in the reading medium.
- Masterblind : testing the usability of auditory feedback in a computer game for blind peoplePublication . Teixeira, Ana Rita; Carvalhal, Ana; Abrantes, Filipe; Lourenço, Vladimiro; Gomes, Anabela; Orvalho, JoaoThe present study presents an adaptation of the Mastermind board game for blind users - Masterblind. Given the focus on visual information in the original game, the game mechanics were simplified and auditory feedback introduced. The research object was to understand what kind of sounds would work better to help blind people play the game. Three versions were presented to the subjects - pentatonic notes, animal sounds and vowels - to help users recall previous steps in the game. The main hypothesis predicted that blind users would consciously benefit from the auditory feedback provided. The second hypothesis predicted that users would benefit less from the feedback that doesn’t provide semantic information. The results were congruent with the hypothesis, although revealing an important role for spatial awareness. Masterblind can be an usable, enjoyable and a challenging experience for blind users as long as it provides semantically significant feedback.
- Natural and artificial lighting: Influence on readabilityPublication . Espada, Sílvia Maria; Teixeira, Ana Rita; Ferreira Antunes, Maria Fernanda; Brito-Costa, SóniaIn the study we present, the effects of different types of light (natural or artificial), different types of texts (scientific and children’s) and different reading formats (on screen and on paper) on our readability are addressed, as well as determining the preference of each participant for reading tasks and to what extent reading with natural light and with influences of artificial light affects their readability in design, and how the reading process could be done more effectively, through manipulation of lighting variables. The experiments were based on different tasks, which required 10 participants, to read two different texts (children’s text and scientific text), in two different formats (print and screen) under two different types of lighting (natural light and artificial light). During reading, we recorded the following parameters: Heart rate and EEG signal (levels of calm, neutral and active (%) using two devices: a heart rate monitor to measure heart rate and Muse, a brain detection headband that uses real-time biofeedback in its brain activity, which we used to monitor brain activity. After completing the protocol, participants answered a questionnaire to collect data on their reading preferences and were composed of three parts: the first part consisted of questions aimed at collecting demographic information from the participants (age, nationality, and other useful data for our research); the second part addressed three questions about the participants reading preferences; the third part was designed to explore the participants opinions about the test and their comfortability. We conclude that participants prefer reading on paper rather than on screen and their performance was better in reading with artificial light. Although reading with natural light was the preference of most participants, reading with artificial light provides better performance in performing the tasks. These findings could help designers to better understand the roles of lighting variables in the reading process and to create light design products that are more efficient, sustainable, and comfortable.
