“…To create interaction models that are independent of a particular interface, research in the field of cartography has evolved taxonomies and topologies that describe single actions such as search, selection, and manipulation (Crampton, 2002;Roth, 2012) in geographic maps. Recording and analyzing such actions allows for optimizations of, for example, the ratio of displayed information or recommendations of individual spatial content (Tahir et al, 2012;Aoidh et al, 2009;Weakliam et al, 2005). Despite this trend, there is only few research that analyzes the semantics of map interaction sequences and thus the usability of the used WebGIS (Roth and MacEachren, 2016;Unrau et al, 2017).…”

Abstract. Due to the increased availability of geospatial data, web-based geographic information systems (WebGIS) have become more popular in recent years. However, the usability of these systems poses new challenges as user interactions are strongly affected by the map and are thus different from interactions with traditional user interface elements. In this paper, we propose a method for evaluating the usability of web-based geographic information systems by analyzing user intentions through map interaction patterns. We use a pattern mining algorithm to extract frequent interaction sequences from user sessions and label these with their interaction semantics that represent the users’ immediate intentions. To evaluate our approach, we conducted a user study with 60 participants in a WebGIS scenario and identified varying user strategies for a selection task based on two different geovisualizations. Our results indicate that the chosen approach can uncover the underlying intentions of users’ interaction patterns and facilitate insights into the usability of WebGIS.

“…Websites should be effective, efficient, and gratifying in their delivery of accurate and timely information [4]. However, when new or unskilled users deal with complicated interfaces, they frequently struggles more [5]. The usefulness of a Graphical User Interface (GUI), especially for persons with poor vision, requires special consideration.…”

Healthcare has evolved significantly over time, from traditional healthcare systems to cuttingedge medical technologies. As these technologies advance, researchers have become interested in their usability. The usefulness of healthcare websites helps to provide more precise medical information. A comprehensive review of the literature is required to identify usability features, techniques, and issues in healthcare websites over a specified time period. In this study, articles from the years 2017-2021 are reviewed from well-known digital libraries i.e, IEEE, ACM, and ScienceDirect that include papers from various conferences, magazines, books, and journals. Initially, the study found 10,512 titles based on the search string developed from the proposed research questions which were then further filtered down to a total of 55 papers. This systematic literature review (SLR) summarises and collects relevant data in response to pre-defined research questions. This analysis of existing research will help website designers and developers, in developing more user-friendly healthcare websites for the users. In the future, this SLR will help in determining the optimal solutions and developing a framework for the identified usability challenges and limitations. It also includes employing the usability evaluation tools discovered by researchers to identify and fix usability issues on websites.INDEX TERMS healthcare websites, usability, usability testing, usability features, usability problems, human-computer interaction.

“…However, only few studies have collected interaction data at a fine granularity to analyze user strategies and objectives. In one such study, Unrau et al (2017) captured and logged mouse clicks and map interactions to detect similar sequences of interactions between multiple users. The data allowed for the identification of unexpected user behavior and, thus, provided insights into the actual usage of the tested WebGIS.…”

“…However, users frequently struggle when performing complex WebGIS interactions, as has been shown by various usability evaluations (Poplin, 2015; Unrau et al, 2017; Unrau & Kray, 2019). Compared with traditional websites, interactions with WebGIS may consist of multiple steps and are affected by the state of the map (e.g., scale and extent).…”

Web-based geographic information systems (WebGIS) are increasingly common and accessed by various types of users.However, evaluating their usability is hard, as interactions with the map and provided functionality can be complex.We present a novel approach to remotely assess WebGIS usability and identify design flaws by logging user interface (UI) interactions and applying pattern mining techniques to the resulting datasets. We conducted an online user study with 40 participants in a realistic WebGIS scenario to validate the approach. The results show that applying this concept can provide insights into user strategies and can reveal usability issues, which can help to improve UIs for WebGIS. Designers can use the methods presented here to assess the usability of their WebGIS rapidly and at scale without carrying out expensive and lengthy in-person user studies. This article also contributes to a better understanding of the challenges and limitations of remotely conducted usability evaluations for WebGIS.
