title: CartoGAZE

description: CartoGAZE constitutes a large eye movement dataset produced during the observation of cartographic products. The production of this dataset was based on the collection of gaze data (SMI RED250) during the observation of the snapshots of 2D static Google navigational maps under free-viewing conditions. The dataset includes the map stimuli, the AOI files, the task descriptions, and full procedural details for the reproducibility of results and to create possibilities for future research.

We aim to develop an automatic and semi-automatic AOI-based analysis model capable of detecting attentive areas from the point of view of human operators, by considering the vector characteristics and visual variables of the map features, task difficulty, expertise, and spatial memory strategies of human operators.

The raw data was collected in the framework of the doctoral research project entitled “Exploring the Cognitive processes of Map Users Employing Eye Tracking and EEG”.

Next to the data_description file, there are six folders in CartoGAZEDatabase.zip; Raw_ET_data, AOIs, Map_stimuli, Final_Fixations, AOIs_all_results, and Calculate_AOI_areas folders; all of which are explained below:
1. Raw_ET_data: The collected eye tracking data in txt format, and can be linked with the map stimuli using the SYNC number in lines with, e.g., # Message: SYNC 103

2. AOIs: The coordinates of AOIs are shared as csv file format.

3. Map stimuli: The snapshots of 2D static Google navigational maps were taken at zoom level 15 and approx. 1:40k scale. The total number of map stimuli used in the experiment is 37 and can be found under Map_stimuli folder in png format. The resolutions of stimuli is provided in excel format in the same folder.

4. The outputs of the scripts can be found in Final Fixations and AOIs_all_results folders as single .csv files organized per stimulus, map feature type, participant and task type. Explanation of columns are as follows:
Column 1: Gaze Position X (Left eye)
Column 1: Gaze Position Y (Left eye)
Column 1: Trial Duration
Column 1: Duration Start
Column 1: Duration End
Column 1: The number of points clustered in the same fixation

In AOI files, the rest of the columns after the above-mentioned 6 columns represent within- or outside-AOIs: 
- If the summary of the rest of the columns ≤1, the fixation is inside the AOI, else outside AOI (represented as 0s and 1s).
These files under AOIs_all_results are also aggregated in one .csv file named “AOI_all_results”.

5. Calculate_AOIs_areas: includes the areas of AOIs (square pixel) separately for each stimulus and map feature type, and aggregated in a single file named “all_AOI_areas.csv”.
