Voice-based web e-Education is a technology-supported learning paradigm that allows phone-access of learners to e-Learning web-based applications. These applications are designed mainly for the visually impaired. They are however lacking in attributes of adaptive and reusable learning objects, which are emerging requirements for applications in these domain. This paper presents a framework for developing intelligent voice-based applications in the context of e-Education. The framework presented supports intelligent components such as adaptation and recommendation services. A prototype Intelligent Voice-based E-Education System (iVEES) was developed and subjected to test by visually impaired users. A usability study was carried out using the International Standard Organization’s (ISO) 9241-11 specification to determine the level of effectiveness, efficiency and user satisfaction. Report of our findings shows that the application is of immense benefit, based on the system’s inherent capacity for taking autonomous decision that are capable of adapting to users’ requests.

Hearing aids can be effective devices to compensate for age- or non-age-related hearing losses. Their overall adoption in the affected population is still low, especially in underdeveloped countries in the subpopulation experiencing milder hearing loss. One of the major reasons for low adoption is the need for repeated complex fitting by professional audiologists, which is often not completed for various reasons. As a result, self-fitting procedures have been appearing as an alternative. Key open questions with these digital tools are linked to their effectiveness, utilized algorithms, and achievable end-results. A digital self-fitting prototype tool with a novel quick four-step fitting workflow was evaluated in a study on 19 individuals with moderate hearing loss. The tool was evaluated in a double-blinded, randomized study, having two study aims: comparing traditional audiological fitting with the new self-fitting tool, which can also be used as a remote tool. The main reported results show moderately high usability and user satisfaction obtained during self-fitting, and quasi-equivalence of the performance of the classical audiological fitting approach. The digital self-fitting tool enables multiple sessions and easy re-fitting, with the potential to outperform the classical fitting approach.

AbstractDue to the increasing number and the complexity of devices in the operation room (OR), which are caused by the diversity and variety of proprietary interface designs, the probability for use errors increases. In order to ensure a safe intraoperative workflow in the OR, integrated OR systems with central work stations have been developed. For this, there also exist concepts for handhelds, which offer touchbased graphical user interfaces (GUI). However, those come along with various limitations, e.g. possibility for one-handed interaction, which is influenced i.a. by the size, the design and the working task. Within our investigations, requirements for an enhanced concept have been gathered by taking into account corresponding standards regarding ergonomics, riskmanagement and usability-engineering. According to DIN EN 60601-2-46, machinery directive 2006/42 EG and guideline VDI/VDE 3850, the stipulated user interface has been designed in order to preselect functions on the touchscreen and their subsequent activation by physical buttons. Furthermore, the accessibility of areas of interest has been considered on the touchscreen, to avoid the re-gripping of the handheld. As a first step, the OR-table control for a tablet has been realized with Microsoft Blend, using a 22’ touch monitor. The usability study has been conducted in accordance with DIN EN ISO 9241-11 and IEC 62366. A group of ten surgeons and OR nurses underwent multiple tasks in the framework of a usability test, comparing the developed concept with a common keypad handheld. The study showed comparable results concerning the usability criteria effectiveness and efficiency. However, the concept clearly outperforms the handheld regarding user satisfaction, in particular due to the higher learnability and the easy transfer of daily-used GUI skills. The current approach motivates to develop a functional model of a touch-based handheld for OR-tables as well as with further integrated OR devices and to conduct additional usability studies.

Previous research on personal health records (PHRs) has focused on applications that are “tethered” to a specific electronic health record (EHR). However, there is a gap in research on the usability of unaffiliated, independent PHRs, as well as research on college-aged PHR users. Therefore, we performed a comparative usability study with 18 college-aged participants on three popular, freely available, independent PHRs. We chose a within-subject design to allow for comparative feedback from each participant in the post-experiment interview. In order to control for a learning effect between PHRs potentially affecting the usability performance measures, the order that participants used the PHRs was randomized across participants. We used analysis of variance (ANOVA) to determine if there were statistically significant differences in the usability measures. Based on variability of PHR use and design reported in previous research, we hypothesized that there would be a significant difference for each of the measures previously described and that one PHR would be the most usable product based on these measures. This hypothesis is based on the PHR’s extensive resources and company history. Participants completed the same six tasks in three different PHRs. Dependent variables included task time, mouse movement, mouse clicks, keystrokes, errors, and user satisfaction ratings based on the Computer System Usability Questionnaire (CSUQ). Analysis of variance (ANOVA) was used to determine the significance in the difference of the means for each dependent variable. Results showed statistically significant differences in CSUQ survey categories, errors, and keystrokes. Results supported one of the three PHRs as having better usability than its tested counterparts. While the initial purpose of this study was comparative usability testing of PHRs for college-aged students, the study provided other insights as well. Similar to other usability studies found in the literature review, the study used multiple methods, including objective task metrics, a survey, and an interview to solicit feedback on the systems. This provides a new addition to the literature in that it analyzes the usability of a system with a new user group and completed a comparative analysis of three leading Web-based, untethered PHRs. The initial hypothesis that there would be a significant difference in usability for each of the dependent measures and that one PHR would have better usability based on these measures was partially supported by the results. While not all of the criteria had statistically significant results for the three different systems, such as task time, mouse movement, mouse clicks, and interface quality, many of the measures did have significant differences in their means, and one of the PHRs had the best results in the majority of metrics analyzed. Though one PHR seemed to more usable than the other systems, it does not imply that this PHR is without error. There are still improvements that could be made to enhance the usability of the system. For example, several participants commented on how they liked the interface of one of the competing PHRs. Several participants also commented that some of the drop-downs limit the options and are not representative of the information they were trying to enter. Expanded dropdowns or typing options could be added to improve this. As found in the a different study, there are still barriers to the adoption of the PHR that was found to be most usable. Using the survey and open-ended survey results as a guide to improvement, the PHR that was found to be most usable in our study has the potential to further improve its usability.

Computer technology has been reported to pose significant usability problems for older users. Further usability problems have been encountered with small, mobile computing devices due to their size as well as age-related declines. This chapter focuses on the usability of mobile computing devices for older people by first employing target users in a study to establish the problems to be addressed when using Personal Digital Assistants (PDAs). The development of an intelligent mobile interface companion called MemorLane to support older people by adapting its presentation and multimodal output of life-cached data to address individual user preferences and physical abilities is then presented, followed by the results of a detailed user-centred evaluation with further target users. Results show that the adaptability to individual requirements and preferences leads to statistically significant improvements both in the usability of the mobile interface and in the levels of user satisfaction experienced.

We have previously found the elderly users to face several usability problems with the current search engines. Thus, we designed an elderly–friendly search interface, Etsin. To evaluate the success of the design, a usability study was conducted for comparing the usability of Etsin and Google. The participants faced fewer usability problems when using Etsin than Google and they valued the clarity of the Etsin interface. In conclusion, elderly users benefit from a simplified search engine interface that is easy to understand and that takes into account age–related issues.

The aim of this paper is to evaluate user satisfaction based on System Usability Scale (SUS) questionnaire on Augmented Reality (AR) application for productive vocabulary using speech recognition. There is still lack of research focus on user satisfaction towards the use of AR-based app using speech recognition for vocabulary learning in early education. The first objective of this paper is to develop an AR application for children using speech recognition to enhance productive vocabulary learning that integrates visual script (orthography) and audio (phonology). The second objective is to evaluate and identify the user satisfaction in enhancing productive vocabulary methods by combining AR technology and speech recognition to the parents and teachers by doing a mixed method testing such as questionnaire and interview. To achieve this, an interview session was conducted with the experts and SUS questionnaire was given to the teachers and parents of the student to evaluate user satisfaction. The results show that the research hypotheses of this study were successfully achieved. It revealed that the teachers and students were satisfied with the application based on SUS score (SUS score > 68). Since the total SUS score is 80.3, which is above average, it shows that they were satisfied with the overall application. Apart from that, the mean of the usability study based on questionnaire also shows that the users have found that this application is usable in terms of learnability study and that this application is easy to use.
