“…7,8 The evaluation of visualization dashboards has been a popular research topic in the health care domain in recent years. [9][10][11] The U.S. Office of the National Coordinator for Health Information Technology has also developed a set of interactive dashboards that provide an overview of facts and statistics about Health IT topics, such as adoption rates and levels of interoperability. 12 Many studies have designed and evaluated visual analytics dashboards, especially those with high interactive and real-time response rates, for how they improve clinical operations and care quality.…”

Background Interactive data visualization and dashboards can be an effective way to explore meaningful patterns in large clinical data sets and to inform quality improvement initiatives. However, these interactive dashboards may have usability issues that undermine their effectiveness. These usability issues can be attributed to mismatched mental models between the designers and the users. Unfortunately, very few evaluation studies in visual analytics have specifically examined such mismatches between these two groups. Objectives We aimed to evaluate the usability of an interactive surgical dashboard and to seek opportunities for improvement. We also aimed to provide empirical evidence to demonstrate the mismatched mental models between the designers and the users of the dashboard. Methods An interactive dashboard was developed in a large congenital heart center. This dashboard provides real-time, interactive access to clinical outcomes data for the surgical program. A mixed-method, two-phase study was conducted to collect user feedback. A group of designers (N = 3) and a purposeful sample of users (N = 12) were recruited. The qualitative data were analyzed thematically. The dashboards were compared using the System Usability Scale (SUS) and qualitative data. Results The participating users gave an average SUS score of 82.9 on the new dashboard and 63.5 on the existing dashboard (p = 0.006). The participants achieved high task accuracy when using the new dashboard. The qualitative analysis revealed three opportunities for improvement. The data analysis and triangulation provided empirical evidence to the mismatched mental models. Conclusion We conducted a mixed-method usability study on an interactive surgical dashboard and identified areas of improvements. Our study design can be an effective and efficient way to evaluate visual analytics systems in health care. We encourage researchers and practitioners to conduct user-centered evaluation and implement education plans to mitigate potential usability challenges and increase user satisfaction and adoption.

This paper presents a projection-based augmented-reality system (MARVIS) that supports the visualization of internal structures on the surface of a liver phantom. MARVIS is endowed with three key features: tracking of spatial relationship between the phantom and the operator’s head in real time, monoscopic projection of internal liver structures onto the phantom surface for 3D perception without additional head-mounted devices, and phantom internal electronic circuit to assess the accuracy of a syringe guidance system. An initial validation was carried out by 25 medical students (12 males and 13 females; mean age, 23.12 years; SD, 1.27 years) and 3 male surgeons (mean age, 43.66 years; SD, 7.57 years). The validation results show that the ratio of failed syringe insertions was reduced from 50% to 30% by adopting the MARVIS projection. The proposed system suitably enhances a surgeon’s spatial perception of a phantom internal structure.

Therefore, a solution for VV may be one based on the direct exploration of 3D images through a physical real-world environment instead of a fixed 3D virtual space representation such as the use of augmented reality technologies [16] .…”

Medical imaging technologies have become an essential component in different areas related to health care. Volume visualization (VV) of medical data is an invaluable support in tasks such as clinical diagnosis, treatment planning, surgery rehearsal, education, and research. Several algorithms and systems have been developed to enable the visualization and interaction with volumetric data. Slice-based visualization methods dominate the field of medical volumes scanning since they allow more detailed analysis of the data. However, an intensive training is usually required for the user to be able to effectively explore the data. In this paper, we present novel a slice-based methodology which objective is to facilitate the exploration of medical volumetric data. The proposed method consist of the use of augmented reality principles to determine the spatial position and orientation of rigid planar objects within a defined space in the real-world which represents the medical volumetric information. The results obtained by a usability study indicate the feasibility of employing this technique for a natural human-computer interaction with the medical data, having the potential of making the process of medical volume exploration more easy and intuitive.
