“…The purposes of the usability study were to test the app's technical functionality and the suitability of the measures and scales employed and, most importantly, to ascertain the participants' overall experience of using the app on a daily basis (Flood, Harrison, Iacob, & Duce, 2012;Nayebi, Desharnais, & Abran, 2012). This is in line with the definition of usability introduced by the International Organization for Standardization (2010).…”

Contact Logger: Measuring everyday intergroup contact experiences in near-time

Intergroup contact research has traditionally relied on retrospective accounts of intergroup encounters, mainly through surveybased or observational methods. This study introduces and tests the usability of a purpose-built, location-aware mobile application-the Contact Logger. This application enables the recording of interpersonal and intergroup encounters, in public and private spaces (both indoor and outdoor), in their here-and-now contexts. The main advantage of this approach, as compared to traditional methods, lies in its ability to collect repeated and timely (near-time) self-assessments of individuals' behaviors and experiences. It also allows for geographical location data to be logged. Usability testing was conducted in a real-world environment and took place over the course of seven days, during which participants (N = 12) logged every contact they had with an outgroup member (here, older people). Subsequently, participants completed a paper-and-pencil questionnaire, reporting on the usability and experience of using the Contact Logger. The results showed that the application is a viable and easy-to-use alternative to traditional methods. The information gathered aided the further development and optimization of the application. The outcomes of this development process are also briefly discussed.

“…Faktor usability merupakan salah satu atribut kualitas perangkat lunak yang merefleksikan bagaimana pengalaman pengguna dalam menggunakan perangkat lunak. Pengalaman pengguna tersebut meliputi tingkat kemudahan perangkat lunak serta kenyamanan pengguna dalam menggunakan perangkat lunak tersebut (Flood, Harrison, Iacob, & Duce, 2012). Bagaimanapun juga dalam proses evaluasi maupun pengujian perangkat lunak pasti melibatkan pengguna sebagai acuan pengukurannya.…”

Dalam proses pengembangan maupun pengujian perangkat lunak, faktor usability merupakan aspek yang paling penting. Evaluasi faktor usability tersebut dapat dilakukan dengan menganalisa orientasi sentimen pada opini pengguna berdasarkan faktor usability. Namun, setiap opini juga memiliki tingkat sentimen yang mencerminkan tinggi rendahnya orientasi sentimen, sehingga akan lebih efektif apabila tingkat sentimen juga dipertimbangkan dalam proses evaluasi. Selain itu, opini pengguna juga dapat memiliki lebih dari 1 faktor usability. Hal tersebut dikarenakan setiap dokumen opini dapat terdiri lebih dari 1 kalimat dimana setiap kalimat bisa memiliki faktor usability yang berbeda. Berbeda dengan perangkat lunak lainnya, aplikasi mobile memiliki batasan dan konteks tersendiri. Sehingga model usability yang digunakan juga berbeda dengan perangkat lunak lainnya. Model PACMAD merupakan model usability yang disesuaikan dengan batasan dan konteks dari aplikasi mobile. Oleh karena itu dalam penelitian ini diusulkan suatu metode evaluasi faktor usability dengan menggunakan klasifikasi multi class pada analisis sentimen dengan mempertimbangkan tingkat sentimen opini pengguna aplikasi mobile berdasarkan model usability PACMAD. Data opini pengguna dikaslifikasian dengan model klasifikasi multi class dengan metode naive bayes, kemudian dianalisis orientasi dan tingkat sentimennya dengan menggunakan metode SentiWordNet Interpretation. Berdasarkan hasil ujicoba diperoleh nilai akurasi sebesar 74,7%, precision 43,2%, recall 29,5% dan f-measure 34,5%.

“…Indeed, if AYA-SBs independently download a publicly available app, their ability to learn to use the app is essential for correct use. On average and based on evaluations of healthy adults, users report spending about 5 min or less learning how to use a new app [19,20], and AYAs have been found to quickly dismiss technological tools that misalign with their expectations [21,22]. Furthermore, AYA-SBs tend to have difficulties with assembled processing (ie, learning to construct and digest information) [23].…”

“…The purpose of this study was to evaluate the usability attribute of learnability for a high-quality [18], publicly available, weight management–focused mobile BIT (smartphone app) for AYA-SBs. We hypothesized that, in evaluating an app rated as having high quality for typically developing populations [18], the majority of users would be able to complete tasks and do so in 5 min or less by their second attempt of a task [19,20]. However, given the variable symptom and functioning profile of AYA-SBs [16], it was anticipated that high variability across the sample would be observed for all evaluated usability metrics.…”

BackgroundAdolescents and young adults with spina bifida (AYA-SBs) have unique user needs, given their variable and complex symptom profile. Owing to multiple barriers to prevention and intervention treatments for secondary conditions (eg, obesity), AYA-SBs may benefit from the use of behavioral intervention technologies (BITs). However, as BITs are often designed and tested with typically developing individuals, it is unclear if existing BITs may be usable for AYA-SBs.ObjectiveThis study aimed to evaluate the usability of a high-quality, publicly available, weight management–focused mobile BIT (smartphone app) for AYA-SBs.MethodsOverall, 28 AYA-SBs attending a Young Men’s Christian Association–based summer camp completed 4 structured usability tasks using a weight management app designed for the general public called My Diet Coach (Bending Spoons). Learnability was measured by (1) time to complete task, (2) number of user errors, and (3) correct entry of data when requested by the app. Satisfaction and general usability were measured via self-reported questionnaires and qualitative feedback following interactions with the app.ResultsThe majority of the sample were able to complete the tasks, with increased completion rates and improved times on second attempts of the tasks (Ps<.05). Errors were common, and discrepancies emerged between quantitative and qualitative feedback such that self-reported measures indicated dissatisfaction but qualitative feedback was generally positive. Suggested improvements to the app included (1) tutorials, (2) simplifying the design, (3) more activity options for those who ambulate by wheelchair, and (4) notifications to prompt use.ConclusionsAYA-SBs were able to learn how to complete specific tasks independently on a weight management app, but design changes consistent with previously proposed user needs were recommended. Rather than designing entirely new BITs, it may be possible to adapt existing technologies to personalize BITs for specific populations such as AYA-SBs.
