Both prototypes score 27 at the NASA TLX (with a variation of 7 for both), which is considered a medium workload (Prabaswari et al, 2019). The only significant difference in the items related to the physical requirement (p = .011): participants found Cybercopter to be more physically demanding than the 2D interface (Figure 10).…”

This paper assesses the usefulness of an interactive and navigable 3D environment to help decision-making in cybersecurity. Malware programs frequently emit periodic signals in network logs; however, normal periodical network activities, such as software updates and data collection activities, mask them. Thus, if automatic systems use periodicity to successfully detect malware, they also detect ordinary activities as suspicious ones and raise false positives. Hence, there is a need to provide tools to sort the alerts raised by such software. Data visualizations can make it easier to categorize these alerts, as proven by previous research. However, traditional visualization tools can struggle to display a large amount of data that needs to be treated in cybersecurity in a clear way. In response, this paper explores the use of Immersive Analytics to interact with complex dataset representations and collect cues for alert classification. We created a prototype that uses a helical representation to underline periodicity in the distribution of one variable of a dataset. We tested this prototype in an alert triage scenario and compared it with a state-of-the-art 2D visualization with regard to the visualization efficiency, usability, workload, and flow induced.

“…Participants perceived that reading the notes imposes a high cognitive workload, i.e., higher than what is considered "optimal" in the literature, especially for tasks with very low physical demands such as reading. 37 This could be due to the high use of medical jargon in the notes which adds burden onto the user, though the simple note was written explicitly aiming to reduce jargon. Thus, techniques to further reduce cognitive workload during interactions with notes are needed.…”

Effect of Notes' Access and Complexity on OpenNotes' Utility

Background: Healthcare providers are now required to provide their patients access to their consultation and progress notes. Early research of this concept, known as “OpenNotes”, showed promising results in terms of provider acceptability and patient adoption, yet objective evaluations relating to patients’ interactions with the notes are limited. Objective: To assess the effect of the complexity level of notes and number of accesses (initial read vs. continuous access) on the user’s performance, perceived usability, cognitive workload, and satisfaction with the notes. Method: We used a 2*2 mixed subjects experimental design with the two independent variables: i) note’s complexity at two levels (simple vs. complex), and ii) number of accesses to notes at two levels (initial vs. continuous). Fifty-three participants were randomly assigned to receive a simple vs. complex radiation oncology clinical note and were tested on their performance for understanding the note content after an initial read, and then with continuous access to the note. Performance was quantified by comparing each participant’s answers to the ones developed by the research team and assigning a score of 0 to 100 based on participants' understanding of the notes. Usability, cognitive workload, and satisfaction of the notes was quantified using validated tools. Results: Performance for understanding was significantly better in simple vs. complex notes with continuous access (p=0.001). Continuous access to the notes was also positively associated with satisfaction scores (p=0.03). The overall perceived usability, cognitive workload, and satisfaction scores were considered low for both simple and complex notes. Conclusion: Simplifying notes can improve understanding of notes for patients/families. However, perceived usability, cognitive workload and satisfaction with even the simplified notes were still low. To make notes more useful for patients and their families, there is a need for dramatic improvements to the overall usability and content of the notes.

“…Each dimension has corresponding items and measures load on a scale from 0-100. According to [Prabaswari, Basumerda, and Utomo, 2019], the score can be interpreted as low (0-10), medium (10-29), somewhat high (30-49), high (50-79), or very high (80-100). Perceived usability, information overload, and tunnel vision were measured through a post-evaluation survey.…”

In homicide investigations, the growing availability of data results in an increasing amount of information and Persons of Interest (PoIs) that can be collected and incorporated during an investigation. This might result in information overload and increased tunnel vision during a homicide investigation. In this paper, we designed a system to support homicide investigations in such a way that it reduces information overload and tunnel vision. For evaluation purposes, we built a prototype that was filled with a fictional homicide investigation. A user study indicated that criminal investigators experienced a significantly low level of information overload and tunnel vision using the prototype. Moreover, the results showed acceptable usability and verbal statements indicated a largely positive attitude towards the prototype. This research clearly shows the opportunity to use interface design artefacts to support the prevention of information overload and tunnel vision.
