Usability Criteria

Hooki Arisan merupakan aplikasi mobile gratis yang menggabungkan fungsi arisan dan pesan instan dalam satu platform. Permasalahannya periode retensi pengguna untuk aplikasi mobile sangat rendah, hanya sekitar 10% pengguna yang ditemukan masih menggunakan aplikasi mobile yang sama setelah enam bulan pengunduhan. Untuk memenuhi tantangan tersebut, usability testing perlu dilakukan untuk verifikasi apakah aplikasi tersebut sudah mencapai tujuannya dan mendapat respon yang baik dari pengguna. Penelitian ini dilakukan untuk menguji aplikasi Hooki Arisan dengan model PACMAD (People At The Center of Mobile Application Development) dengan pendekatan GQM (Goal Question Metrics) pada tujuh atribut usabiliy yaitu efficiency, effectiveness, learnability, memorability, errors, satisfaction, dan cognitive load. Tujuan penelitian ini yaitu untuk mengetahui hasil usability testing dan rekomendasi perbaikan pada aplikasi Hooki Arisan. Setelah melakukan usability testing pada aplikasi Hooki Arisan dengan metode Performance Measurement, Retrospective Think Aloud (RTA), dan Kuesioner CSUQ dapat disimpulkan bahwa aplikasi Hooki Arisan mencakupi aspek Efficiency dengan tingkat kecepatan 0,001432422 tiap detiknya; Effectiveness 83%; Learnability 72,91667%. ; Memorability 82,932%.; Errors 22%; Satisfaction 73.15% dan juga memenuhi aspek Cognitive Load. Aplikasi Hooki Arisan mampu memenuhi kriteria usability sebuah aplikasi mobile karena dinilai telah mencakupi ke-tujuh variabel usability model PACMAD. Untuk menginkatkan tingkat usability aplikasi Hooki Arisan dalam penelitian ini dirancang rekomendasi halaman aplikasi Hooki Arisan dengan membuat wireframe, dimana dasar yang digunakan untuk mengembangkan rekomendasi hasil data usability testing yaitu performance measurement dan RTA.Kata Kunci : CSUQ, Hooki Arisan , PACMAD, Performance Measurement, RTA, Usability. Hooki Arisan is a free mobile application that combines social gathering and instant messaging functions on one platform. The problem is that the user retention period for mobile applications is very low, only about 10% of users found still use the same mobile application after six months of downloading. To meet these challenges, usability testing needs to be done to verify whether the application has reached its purpose and gets a good response from the user. This study was conducted to examine the application of Hooki Arisan with the PACMAD model (People At The Center of Mobile Application Development) with the GQM (Goal Question Metrics) approach on seven usability attributes, such as efficiency, effectiveness, learnability, memorability, errors, satisfaction, and cognitive load. The purpose of this study is to determine the results of usability testing and recommendations for improvements of Hooki Arisan application. After conducting usability testing on the Hooki Arisan application using the Performance Measurement, Retrospective Think Aloud (RTA) method, and the CSUQ Questionnaire it can be concluded that the Hooki Arisan application covers the Efficiency aspect with a speed level of 0.001432422 every second; Effectiveness 83%; Learnability 72,91667%. ; Memorability 82.932% .; Errors 22%; satisfaction 73.15% and also fulfill the Cognitive Load aspect. The Hooki Arisan application is able to meet the usability criteria of a mobile application because it is considered to have covered the seven usability variables of the PACMAD model. To improve the level of usability of the Hooki Arisan application in this study, we designed the recommendations of the Hooki Arisan application page by creating wireframe, where the basis used to develop the recommendations of the results of usability testing data was performance measurement and RTA.keyword : CSUQ, Hooki Arisan, PACMAD, Performance Measurement, RTA, Usability.

This study presents the results on the usability testing done on Golden Screen Cinema (GSC) mobile appli-cation at two sites: Polytechnic Balik Pulau, Penang and Poly-Tech College Mara (KPTM) Alor Setar, Kedah. The purpose of the testing was to elicit the overall reactions of users to the GSC mobile application with respect to the user interface, terminology and information, application capability and general impression. There were twenty volunteer participants who were recruited for the usability testing. Ten were used at Polytechnic Balik Pulau, Penang while the other ten were used at Kolej Polytech Technology Mara, Alor Setar. Of the 20 participants,17 had no prior experiences on the use of GSC mobile application while 3 had experience on the use of GSC mobile application. The test result showed that the GSC app is both effective and efficient. Thus, indicating that the mobile application has good usability in terms effectiveness and efficiency. However, the participants' facial expressions and body language while performing tasks revealed that some of them had some challenges. Features in the GSC app, such as choosing seats and making payment made some of the participants react uneasily and with caution because of their lack of confidence as it had to do with financial matters. Based on observation, most of the participants looked nervous and felt uneasy during the session. This was so even though a brief briefing about the test was given to avoid such nervousness.

AbstractThis paper presents results of the effect of different translation modalities on users when working with the Microsoft Word user interface. An experimental study was set up with 84 Japanese, German, Spanish, and English native speakers working with Microsoft Word in three modalities: the published translated version, a machine translated (MT) version (with unedited MT strings incorporated into the MS Word interface) and the published English version. An eye-tracker measured the cognitive load and usability according to the ISO/TR 16982 guidelines: i.e., effectiveness, efficiency, and satisfaction followed by retrospective think-aloud protocol. The results show that the users’ effectiveness (number of tasks completed) does not significantly differ due to the translation modality. However, their efficiency (time for task completion) and self-reported satisfaction are significantly higher when working with the released product as opposed to the unedited MT version, especially when participants are less experienced. The eye-tracking results show that users experience a higher cognitive load when working with MT and with the human-translated versions as opposed to the English original. The results suggest that language and translation modality play a significant role in the usability of software products whether users complete the given tasks or not and even if they are unaware that MT was used to translate the interface.

PurposeThis study explores the effects of cognitive load on the propensity to reformulate queries during information seeking on the web.Design/methodology/approachThis study employs an experimental design to analyze the effect of manipulations of cognitive load on the propensity for query reformulation between experimental and control groups. In total, three affective components that contribute to cognitive load were manipulated: mental demand, temporal demand and frustration.FindingsA significant difference in the propensity of query reformulation behavior was found between searchers exposed to cognitive load manipulations and searchers who were not exposed. Those exposed to cognitive load manipulations made half as many search query reformulations as searchers not exposed. Furthermore, the National Aeronautical and Space Administration Task Load Index (NASA-TLX) cognitive load scores of searchers who were exposed to the three cognitive load manipulations were higher than those of searchers who were not exposed indicating that the manipulation was effective. Query reformulation behavior did not differ across task types.Originality/valueThe findings suggest that a dual-task method and NASA-TLX assessment serve as good indicators of cognitive load. Because the findings show that cognitive load hinders a searcher's interaction with information search tools, this study provides empirical support for reducing cognitive load when designing information systems or user interfaces.
