“…System Usability Scale scores can range from 0 to 100, where higher scores indicate better usability. Scores of 70 or above are considered to be acceptable, with better products scoring in the high 70s or above [17]. The mean System Usability Scale score for the LVM was 78 (range 58-93).…”

Summary:Digital pathology promises a number of benefits in efficiency in surgical pathology, yet the longer time required to review a virtual slide than a glass slide currently represents a significant barrier to the routine use of digital pathology. We aimed to create a novel workstation that enables pathologists to view a case as quickly as on the conventional microscope. The Leeds Virtual Microscope (LVM) was evaluated using a mixed factorial experimental design. Twelve consultant pathologists took part, each viewing one long cancer case (12-25 slides) on the LVM and one on a conventional microscope. Total time taken and diagnostic confidence were similar for the microscope and LVM, as was the mean slide viewing time. On the LVM, participants spent a significantly greater proportion of the total task time viewing slides and revisited slides more often. The unique design of the LVM, enabling real time rendering of virtual slides while providing users with a quick and intuitive way to navigate within and between slides, makes use of digital pathology in routine practice a realistic possibility. With further practice with the system, diagnostic efficiency on the LVM is likely to increase yet more.3

“…-SUS Scores and User Opinion: Subjects rated usability at 86 out of 100 on the System Usability Scale (SUS) [11]. This is far above the "industry average" of 70.1 reported in [9], and indicates excellent usability and acceptability. Also, a staggering 96.67% (29 subjects) stated that they would like to see the system implemented on their own personal tags.…”

Abstract. The recent emergence of RFID tags capable of performing public key operations has enabled a number of new applications in commerce (e.g., RFIDenabled credit cards) and security (e.g., ePassports and access-control badges). While the use of public key cryptography in RFID tags mitigates many difficult security issues, certain important usability-related issues remain, particularly when RFID tags are used for financial transactions or for bearer identification. In this paper, we focus exclusively on techniques with user involvement for secure user-to-tag authentication, transaction verification, reader expiration and revocation checking, as well as association of RFID tags with other personal devices. Our approach is based on two factors: (1) recent advances in hardware and manufacturing have made it possible to mass-produce inexpensive passive displayequipped RFID tags, and (2) high-end RFID tags used in financial transactions or identification are usually attended by a human user (namely the owner). Our techniques rely on user involvement coupled with on-tag displays to achieve better security and privacy. Since user acceptance is a crucial factor in this context, we thoroughly evaluate the usability of all considered methods through comprehensive user studies and report on our findings.

“…Using the descriptors suggested by Bangor et al (2008) [41], the score can be described as "excellent". 50% of the total average SUS score fell between 76.3 and 92.5 and 25% had a score higher than 92.5, suggesting that more than 75% of the app sample assessed could be described as having "good" to "excellent" usability.…”

“…SUS is a valid and reliable measure of overall usability (from 0 to 100) and consists of 10 items that are ranked on a 5-point Likert scale, from "strongly disagree" to "strongly agree". The wording of the 8th statement was changed from "cumbersome" to "awkward" as recommended [41][42][43]. Second, the word "system" was replaced by "app" to make the scale applicable to the sample in this study.…”

Background: Within the new digital health landscape, the rise of health apps creates novel prospects for health promotion. The market is saturated with apps that aim to increase physical activity (PA). Despite the wide distribution and popularity of PA apps, there are limited data on their effectiveness, user experience, and safety of personal data. Objective: The purpose of this review and content analysis was to evaluate the quality of the most popular PA apps on the market using healthcare quality indicators. Methods: The top-ranked 400 free and paid apps from iTunes and Google Play stores were screened. Apps were included if the primary behavior targeted was PA; targeted users were adults; the apps had stand-alone functionality. The apps were downloaded on mobile phones and assessed by two reviewers against the following quality assessment criteria: 1) users' data privacy and security, 2) presence of
