Perceived Usability

Aesthetics and usability both play critical roles in product design. But how might measurement of these two conceptually-different features of products interfere with one another? The current research study examines the effect of differences in aesthetics on perceived usability. Participants completed three tasks on a simulated website with a low usability interface. One group of participants used an interface with high aesthetics, whereas a second group interacted with an interface with poor aesthetics. Both groups rated the usability and aesthetics of the interface after completing the tasks. The aesthetics manipulation was effective in that the high aesthetics group provided higher ratings on two aesthetics scales than did the low aesthetics group; however, differences in aesthetics had no significant effect on usability as measured by the System Usability Scale (SUS). These findings support the idea that users make independent judgments of usability and aesthetics.

Form Variant

Objective: To assess versions of the shorter form variant of Usability Metric for User Experience (UMUX-LITE) questionnaire differing in the number of response options for the items (3, 5, 7, and 11). Background: The UMUX-LITE is an efficient (two-item) standardized questionnaire that measures perceived usability. A growing body of evidence shows it closely corresponds to one of the most widely used standardized usability questionnaires, the System Usability Scale (SUS), with regard to both correlation and magnitude of concurrently collected means. Although the “standard” version of the UMUX-LITE uses items with seven response options, there is some variance in practice. Method: Members of a corporate user experience panel ( n = 242) completed surveys rating a recent Web site experience with the SUS and UMUX-LITE, also providing ratings of overall experience and likelihood-to-recommend. Results: Scale reliabilities were acceptable (coefficient α >.70) with the exception of UMUX-LITE with three response options. All UMUX-LITE correlations with SUS, overall experience, and likelihood-to-recommend were highly significant. For likelihood-to-recommend, there was a significant difference in the magnitude of correlations, with 11 response options higher than three. Although some statistically significant differences were observed in correspondence between SUS and UMUX-LITE scores, these did not seem to translate to practically significant differences. Conclusion: The number of UMUX-LITE response options does not matter much, especially in practice. Because the version with three response options showed some weakness with regard to reliability and correlation with likelihood-to-recommend, practitioners should avoid it. Application: Unless there is a strong reason to do otherwise, use the “standard” version with seven response options.

Perceived Usability

<h4>Perceived usability affects greatly student’s learning effectiveness and overall learning experience, and thus is an important requirement of educational software. The System Usability Scale (SUS) is a well-researched and widely used questionnaire for perceived usability evaluation. However, surprisingly few studies have used SUS to evaluate the perceived usability of learning management systems (LMSs). This paper presents an empirical evaluation of the SUS questionnaire in the context of LMSs’ perceived usability evaluation. Eleven studies involving 769 students were conducted, in which participants evaluated the usability of two LMSs (eClass and Moodle) used within courses of their curriculum. It was found that the perceived usability of the evaluated LMSs is at a satisfactory level (mean SUS score 76.27). Analysis of the results also demonstrated the validity and reliability of SUS for LMSs’ evaluation, and that it remains robust even for small sample sizes. Moreover, the following SUS attributes were investigated in the context of LMSs evaluation: gender, age, prior experience with the LMS, Internet self-efficacy, attitude towards the Internet and usage frequency of the LMS.</h4>

Aviation Weather

Previous research suggests that a lack of weather knowledge and poor usability of weather displays may be contributing to aviation weather-related accidents. The purpose of this study was to analyze the perceived usability and performance of pilots while using different parts of the Aviation Weather Center (AWC) website. On average, pilots rated Radar the highest, followed by Terminal Aerodrome Forecasts (TAFs), and then Satellite on the System Usability Scale. Performance measures and the post-study interview revealed further insight into what aspects of the AWC are giving pilots difficulties.

The application of interactive learning multimedia is one of the factors that impact the learning process for achieving learning outcomes. In developing a mobile application, the main principle is usability. This research goal is to presents a usability evaluation of the Jawara Sains, which is a mobile application to learn science subjects. This research used a System Usability Scale (SUS) questionnaire to measure the level of users’ perceived usability. This score can indicate the usability performance of effectiveness, efficiency, and ease of use. Jawara Sains's SUS score achieved 75.45, which indicates a B grade, acceptable, and categorized in the good range. This score can also indicate whether a user is a promoter or not. The analysis showed that the Jawara Sains is categorized into the passive Net Promoter Score (NPS), which means users will not influence other people. Therefore, recommendations are needed for its usability improvements.

Acute Event

Recovery of therapeutic or functional ambulatory capacity in patients with rotator cuff injury is a primary goal of rehabilitation. Wearable powered exoskeletons allow patients to perform repetitive practice with large movements to maximize recovery, even immediately after the acute event. The aim of this paper is to describe the usability, acceptability and acceptance of a hybrid exoskeleton for upper-limb passive rehabilitation using the System Usability Scale (SUS) questionnaire. This equipment, called ExoFlex, is defined as a hybrid exoskeleton since it is made up of rigid and soft components. The exoskeleton mechanical description is presented along with its control system and the way motion is structured in rehabilitation sessions. Seven patients (six women and one man) have participated in the evaluation of this equipment, which are in the range of 50 to 79 years old. Preliminary evidence of the acceptance and usability by both patients and clinicians are very promising, obtaining an average score of 80.71 in the SUS test, as well as good results in a questionnaire that evaluates the clinicians’ perceived usability of ExoFlex.

Subjective Usability

Researchers recently demonstrated that subjective usability assessments of common products do not vary across geographic locations. That study did not directly address mobile applications, which are some of the most ubiquitous and geographically diverse systems in use in the United States today. To address this shortcoming, this article examined whether or not geographic location impacts the perceived usability of mobile applications by having 2,590 participants from different regions of the United States rate the usability of several mobile applications using the System Usability Scale. There was a lack of evidence to support statistically significant differences in usability scores across geographic locations for 95% of the mobile applications evaluated. This suggests that system usability assessments for mobile products do not differ across US locations. These findings further reinforce the idea that participants from any locale can be recruited for usability tests as long as all other critical demographic criteria are met.
