Avazum app usability testing.

To verify the effectiveness, efficiency, and satisfaction in the usability test of the tinnitus assessment application. This is a descriptive usability test study that assessed the satisfaction, effectiveness, and efficiency of the application. The test was carried out virtually via Google Forms. First, the participants received instructions on how to access and use Avazum, through texts and illustrative images. Afterward, the users used the application, observing its functions and usability. Next, the participants answered the usability questionnaire. Statistical analysis was performed using the Statistical Package for the Social Sciences, version 21.0, to perform descriptive analysis such as frequency, percentages of data in the System Usability Questionnaire (SUS), and analysis in the Net Promoter Score (NPS). Thus, the overall mean SUS score was consistent with satisfactory usability, which implies that the application does not present serious usability problems. Also, the overall NPS percentage indicated very good user satisfaction, with a good percentage of promoting users. As far as effectiveness is concerned, it was found that Avazum reached its goals, besides being efficient, as it uses clear language and is comfortably used. Avazum obtained very good satisfaction from users, in addition to achieving its goals. It proved to be effective, has clear language, and is comfortably used, adducing efficiency in the multidisciplinary evaluation of tinnitus.

Virtual reality simulation for learning wound dressing: Acceptance and usability

BackgroundUsing virtual reality (VR) for clinical training is a promising pedagogical approach. This study evaluated virtual wound dressing simulators developed for learning the basic skills. MethodsA desktop simulator (DTS) and an immersive simulator (IMS) were evaluated by 30 nursing students. Knowledge test (KT), user acceptance questionnaire (UAQ) and system usability questionnaire (SUQ) were administered after using the simulators. ResultsThe mean KT scores for DTS and IMS were similar. The mean UAQ and SUQ scores for IMS were relatively higher. Positive feedback was obtained, with IMS favored for higher level of realism and DTS for being more convenient to use. ConclusionBoth simulators can promote engaging learning experience and facilitate wound dressing training.

Clients and professionals elicit long-term care preferences by using 'What matters to me': A process evaluation in the Netherlands.

Background‘What matters to me’ is a five‐category preference elicitation tool to assist clients and professionals in choosing long‐term care. This study aimed to evaluate the use of and experiences with this tool.MethodsA mixed‐method process evaluation was applied. Participants were 71 clients or relatives, and 12 professionals. They were all involved in decision‐making on long‐term care. Data collection comprised online user activity logs (N = 71), questionnaires (N = 38) and interviews (N = 20). Descriptive statistics was used for quantitative data, and a thematic analysis for qualitative data.ResultsSixty‐nine per cent of participants completed one or more categories in an average time of 6.9 (±0.03) minutes. The tool was rated 6.63 (±0.88) of 7 in the Post‐Study System Usability Questionnaire (PSSUQ). Ninety‐five per cent experienced the tool as useful in practice. Suggestions for improvement included a separate version for relatives and a non‐digital version. Although professionals thought the potentially extended consultation time could be problematic, all participants would recommend the tool to others.Conclusion‘What matters to me’ seems useful to assist clients and professionals with preference elicitation in long‐term care. Evaluation of the impact on consultations between clients and professionals by using ‘What matters to me’ is needed.

Incorporating gamification into website design to facilitate effective communication

Gamification is not simply a temporary trend but would result in huge changes in life, education and marketing. Under the trend, design researchers should focus on the importance of gamification and apply gamification in the improvement of effective communication. This study aims to apply gamification to website design for facilitating effective communication. Two experimental websites, including a gamification incorporated website and a no-gamification incorporated website, are constructed. Users are recruited to use individual websites. After the website experience, task questions, system usability scale, online questionnaire and retrospective thinking aloud are applied to collect user feedback. The data analyses reveal that ‘gamification incorporated website’ could not promote the usability of websites, while learnability, pleasure, engagement and satisfaction are enhanced. Overall speaking, applying gamification to websites could actually enhance communication efficiency. The gamification design guidelines are eventually proposed to assist future designers in constructing meaningful gamification design with communication efficiency.

Abstract W P135: Usability of a Virtual Reality Tool for In-Home Stroke Rehabilitation: A Case Series

Stroke is the leading cause of serious, long-term disability in the United States. Exercise and activity in the chronic phase of stroke have shown to be beneficial in achieving and maintaining improvements in motor and ADL function. Interactive video games and virtual reality (VR) have also shown to be effective in improving motor function following stroke. We developed a prototype VR rehabilitation tool called Mystic Isle that uses the Microsoft Kinect sensor and a standard PC. The purpose of this case series was to explore the usability of Mystic Isle as a 5-week intervention to improve performance of client identified activities for adults (>21 years) with chronic stroke (>6 months post) in the home setting. Three participants with chronic stroke completed the five week intervention. Outcomes were measured at baseline, immediately pre-intervention (after a 2 week delay from baseline), and immediately post-intervention. The intervention was conducted in each participant’s home. The results of the Canadian Occupational Performance Measure at baseline guided the choice of the virtual tasks for the intervention. The participants were instructed to complete 4 hours each week. The primary outcome was usability and feasibility of the intervention measured with the Game Experience Questionnaire, the System Usability Questionnaire, and a semi-structured interview. Primary outcome data were analyzed using a mixed methods grounded theory approach. Secondary outcomes included motor impairment, quality of life and occupational performance measured using standard clinical measures. Two of the three participants had very positive responses to the intervention and use of the VR tool in the home setting. All three participants demonstrated improvements in quality of life from pre- to post-intervention and improvements in motor function were scattered across participants. All participants expressed the desire to use the system in the future if improvements were made to increase the usability of the system for the home setting. They also spoke about how they attempted to integrate the game into their daily routine or schedule. A major barrier to use for all participants was a busy day that left them too fatigued to interact with the system and complete the intervention.

IBM computer usability satisfaction questionnaires: Psychometric evaluation and instructions for use

This article describes recent research in subjective usability measurement at IBM, focused on evaluating the psychometric properties of questionnaires designed for use in scenario‐based usability evaluation. The questionnaires address evaluation at both a global overall system level and at a more detailed scenario level. The primary goals of this article are to (a) discuss the psychometric characteristics of IBM questionnaires that measure user satisfaction with computer system usability, and (b) provide the questionnaires, with administration and scoring instructions. For scenario‐level measurement, the 3‐item After‐Scenario Questionnaire (ASQ) has excellent internal consistency, with coefficient alphas across a set of scenarios ranging from .90 to .96. For more global assessment, the Post‐Study System Usability Questionnaire (PSSUQ) also has excellent internal consistency, with an overall coefficient alpha of .97. Preliminary principal factor analysis of 48 PSSUQ questionnaires suggested the presence of...
