Raster maps provide intuitive visualizations of remote sensing data representing various phenomena on the Earth’s surface. Reading raster maps with intricate information requires a high cognitive workload, especially when it is necessary to identify and compare values between multiple layers. In traditional methods, users need to repeatedly move their mouse and switch their visual focus between the map content and legend to interpret various grid value meanings. Such methods are ineffective and may lead to the loss of visual context for users. In this research, we aim to explore the potential benefits and drawbacks of gaze-adaptive interactions when interpreting raster maps. We focus on the usability of the use of low-cost eye trackers on gaze-based interactions. We designed two gaze-adaptive methods, gaze fixed and gaze dynamic adaptations, for identifying and comparing raster values between multilayers. In both methods, the grid content of different layers is adaptively adjusted depending on the user’s visual focus. We then conducted a user experiment by comparing such adaptation methods with a mouse dynamic adaptation method and a traditional method. Thirty-one participants (n = 31) were asked to complete a series of single-layer identification and multilayer comparison tasks. The results indicated that although gaze interaction with adaptive legends confused participants in single-layer identification, it improved multilayer comparison efficiency and effectiveness. The gaze-adaptive approach was well received by the participants overall, but was also perceived to be distracting and insensitive. By analyzing the participants’ eye movement data, we found that different methods exhibited significant differences in visual behaviors. The results are helpful for gaze-driven adaptation research in (geo)visualization in the future.

This chapter addresses the online variant of the container-stacking problem that the first French container port of Le Havre faces. This problem occurs when terminals are subjected to unpredictable changes and when information about the storage process cannot be available a priori to plan for containers' storage. In such cases, containers should be stored online, dynamically, and according to the terminal's current state. For that, the authors suggest making multi-criteria decisions to select container's position. They propose an online multi-levels heuristic approach that determines, at each level, where a container should be stored. They use the TOPSIS method to solve the multi-criteria decision-making problem. In order to define the value of the weights of the criteria in TOPSIS, they suggest a simulation optimization approach that can be carried out offline. The approach is used to solve the real problem of container stacking in a new intermodal terminal in the Paris region, and the results show that the approach performs better than standard online stacking rules.
