“…They concluded that vividness/distinctiveness is a major factor of route memorization. This corresponds to Cybulski and Medyńska-Gulij's [39] findings that cartographic redundancy is influential in the change detection of animated stimuli.…”

“…Already, Wilkening and Fabrikant [69] noticed in their research that time pressure negatively affects map-based related tasks. The difficulty is an aspect of the animation that is crucial for effectiveness, as has been proven in many recent studies [8,25,39]. Moreover, this study proves that the number of turns of an animated route reduces the effectiveness of memorizing by several percent.…”

There is no consensus on the importance of satellite images in the process of memorizing a route from a map image, especially if the route is displayed on the Internet using dynamic (animated) cartographic visualization. In modern dynamic maps built with JavaScript APIs, background layers can be easily altered by map users. The animation attracts people’s attention better than static images, but it causes some perceptual problems. This study examined the influence of the number of turns on the effectiveness (correctness) and efficiency of memorizing the animated route on different cartographic backgrounds. The routes of three difficulty levels, based on satellite and road background, were compared. The results show that the satellite background was not a significant factor influencing the efficiency and effectiveness of route memorizing. Recordings of the eye movement confirmed this. The study reveals that there were intergroup differences in participants' visual behavior. Participants who described their spatial abilities as “very good” performed better (in terms of effectiveness and efficiency) in route memorizing tasks. For future research, there is a need to study route variability and its impact on participants’ performance. Moreover, future studies should involve differences in route visualization (e.g., without and with ephemeral or permanent trail).

“…Cartographers explored a number of ways to reduce cognitive load and make animations more accessible. While many ideas are related to the user interface design with the implicit or explicit goal to minimize split attention and/or maximize user control [9][10][11][12][13][14], others focus on the transition between time-steps [15,16], on techniques to highlight important changes [17], or on the relation between data complexity and animation speed. Multimäki and Ahonen-Rainio [18] equalize the temporal scale according to the temporal density of change, slowing down the animation in busy times, while increasing animation pace when the number of changes is low.…”

Time series animation of choropleth maps easily exceeds our perceptual limits. In this empirical research, we investigate the effect of local outlier preserving value generalization of animated choropleth maps on the ability to detect general trends and local deviations thereof. Comparing generalization in space, in time, and in a combination of both dimensions, value smoothing based on a first order spatial neighborhood facilitated the detection of local outliers best, followed by the spatiotemporal and temporal generalization variants. We did not find any evidence that value generalization helps in detecting global trends.

The work presents study on coordinated and multiple views (CMV) geovisualisation tools, i.e., interactive tools consisting of several views presenting spatial data in various forms, including maps. The study covers both theoretical considerations and eye-tracking empirical study. Among other things, the author aimed to explore how inexperienced users learn and work with CMV geovisualization tools. On this basis, guidelines were formulated for CMV designers and authors of training materials supporting these tools.
