Recently, technology has been advancing and making some aspects of life simpler. Most people have an intelligent mobile device. These devices have applications that support users to perform various tasks. However, these applications are developed for users who don't have any type of disability. This chapter focuses on making use of some tools that exist within the area of software engineering (SE) and user experience (UX) with the aim of developing an interactive software system (ISS). It is expected that this ISS will support people with visual disabilities to learn Braille. To develop the ISS, the authors use modified usability and UX evaluation methods for blind people. The methodology to be followed is based on the ISO15288: 2015 standard of the SE. The methods used to perform the evaluation tests with blind users are card sorting and thinking aloud. Based on the results, it is observed that the ISS complies with most of the UX factors, such as ease of use, accessibility, and utility, so they expect the ISS to be usable for blind people.

BACKGROUND Mobile devices such as tablets and smartphones are increasingly used in health care in many developed countries. Nurses form the largest group in health care that uses electronic health records (EHRs) and their mobile versions. Mobile devices are suggested to promote nurses’ workflow, constant updating of patient information and improve the communication within the health care team. However, little is known about their effect on nurses’ wellbeing. OBJECTIVE The present study aimed to examine the association of mobile device use of the EHR with nurses’ perceived time pressure, stress related to information systems (SRIS) and self-rated stress. Moreover, we examined whether mobile device use modifies the associations of EHR usability (ease of use and technical quality), experience in using EHRs and number of systems in daily use with these wellbeing indicators. METHODS The present study was a cross-sectional population-based survey study among 3,610 Finnish registered nurses gathered in 2020. The associations were examined using analyses of covariance and logistic regression adjusted for age, gender and employment sector (hospital, primary care, social service and other). RESULTS Those who used mobile version of their EHR had higher levels of time pressure ( F(1)= 14.96, p < .001) and SRIS ( F(1)= 6.11, p = .01) compared to those who did not use mobile versions. Moreover, the interactions of mobile device use with experience in using EHRs (F(1) = 14.93, p < .001), ease of use (F(1) = 10.16, p = .001) and technical quality (F(1) = 6.45, p = .01) were significant for SRIS. Inexperience in using EHRs, low levels of ease of use and technical quality were associated with higher SRIS and this association was more pronounced among those who used mobile devices. That is, the highest levels of SRIS were perceived among those who used mobile devices and were inexperienced EHR users, perceived low levels of ease of use or low levels of technical quality of their EHR. CONCLUSIONS According to our results it seems that at the moment mobile device use is not beneficial for the nurses’ wellbeing. In addition, mobile device use seems to intensify the negative effects of usability problems of the EHRs. Especially inexperienced users of EHRs seem be at disadvantage when using mobile devices. Thus, we suggest that EHRs and their mobile versions should be improved in a manner that they would be easier to use and would better support the nurses’ workflow. For example, improvements to problems related to small display, user interface and difficult data entry of mobile versions might be useful. Moreover, more training related to EHRs, their mobile versions and workflow related to these should be provided to nurses.

In order to compare the strategies consumers use to make predictions about the ease-of-use of products, the authors conducted a card sorting exercise with subject-matter experts (SMEs) to refine a coding scheme from current, widely-used usability definitions and measurement tools. Nine SMEs sorted 83 cards containing aspects found in usability definitions, guidelines, measurement tools and descriptions. The resulting fifteen clusters define a coding scheme that is both comprehensive and flexible. The refined taxonomy does not seek to redefine usability, but to provide a mechanism for researchers wanting to use a coding scheme that includes methods for classifying strategies such as usability attribution to system features, metacognitive behaviors (planning and evaluating), and exemplar-based strategies (memory for performing similar tasks).

Abstract Background Measurement-based care (MBC) is the practice of routinely administering standardized measures to support clinical decision-making and monitor treatment progress. Despite evidence of its effectiveness, MBC is rarely adopted in routine substance use disorder (SUD) treatment settings and little is known about the factors that may improve its adoptability in these settings. The current study gathered qualitative data from SUD treatment clinicians about their perceptions of MBC, the clinical outcomes they would most like to monitor in MBC, and suggestions for the design and implementation of MBC systems in their settings. Methods Fifteen clinicians from one publicly-funded and two privately-funded outpatient SUD treatment clinics participated in one-on-one research interviews. Interviews focused on clinicians’ perceived benefits, drawbacks, and ideas related to implementing MBC technology into their clinical workflows. Interviews were audio recorded, transcribed, and coded to allow for thematic analysis using a mixed deductive and inductive approach. Clinicians also completed a card sorting task to rate the perceived helpfulness of routinely measuring and monitoring different treatment outcomes. Results Clinicians reported several potential benefits of MBC, including improved patient-provider communication, client empowerment, and improved communication between clinicians. Clinicians also expressed potential drawbacks, including concerns about subjectivity in patient self-reports, limits to personalization, increased time burdens, and needing to learn to use new technologies. Clinicians generated several ideas and preferences aimed at minimizing burden of MBC, illustrating clinical changes over time, improving ease of use, and improving personalization. Numerous patient outcomes were identified as “very helpful” to track, including coping skills, social support, and motivation for change. Conclusions MBC may be a beneficial tool for improving clinical care in SUD treatment settings. MBC tools may be particularly adoptable if they are compatible with existing workflows, help illustrate gradual and nonlinear progress in SUD treatment, measure outcomes perceived as clinically useful, accommodate multiple use cases and stakeholder groups, and are framed as an additional source of information meant to augment, rather than replace, existing practices and information sources.

Linear B

Linear-B script has been studied for sixty years since its decipherment. The laborious efforts of the scholars have revealed many linguistic aspects of the oldest known form of Greek (i.e., Mycenaean/Danaic Greek), thus allowing the study of this Indo-European language and its dynamics for thirty-five centuries. In addition, linguistic phenomena closer to the roots of Indo-European languages can be also studied. Yet, the limited usage of Linear-B script, merely for keeping records, and its incompatibility to the Greek phonotactics causes misinterpretations of various kinds. The study of Linear-B was not supported till recently by interactive software tools that would facilitate both research and training. Especially for Greek speakers, the resources are even more limited. This paper presents the development of an interactive software system for the study, learning and researching of Linear-B by Greek speakers. This software system is also suggested as a model for the interpretation of other archaic languages.

The Way

Hedonic utility scale is a user experience (UX) evaluation method that, through a questionnaire, collects the hedonic and utilitarian dimensions of a product by rating items belonging to each dimension. In this chapter, it is proposed to adapt this method for its application with blind users using the Google TalkBack tutorial as a case study. Based on Nielsen's heuristics, five blind users rated the tutorial after completing each of its five tasks. To ensure inclusiveness in the adaptation of the method, this could be answered verbally and with the use of cards written in Braille, while, for questions of practicality in the evaluation, the number of items was reduced as well as changed the way of scoring (scale and equations) with respect to the original HED/UT. The scale of grades was ranked from 1 (very little) to 5 (quite), getting TalkBack scores between 4 and 5. The results show that the TalkBack tutorial is generally well accepted and well rated by users in both dimensions (hedonic and utility).
