ALT Figure 5: Example of a linear zoom, where the gaze follows a linear translation regarding the map location during the zoom. The image shows a map background (from OpenStreetMap) with place names like Nevillers, Fouqueroles, and Le Fay-Saint-Quentin visible. Multiple translucent green circles of varying sizes are positioned along a roughly horizontal black line crossing the map from left to right. Each circle represents a fixation point with a radius related to the zoom level of the map at the time of the fixation - larger circles indicate higher zoom levels (zoomed out view), while smaller circles indicate lower zoom levels (zoomed in view). The different shades of green represent different interactions that occurred during the map exploration. A scale bar showing '1500 m' appears in the lower left corner. The circles overlap in sequence, creating a visual trail of the user's gaze path and zoom behavior during map navigation.
