VIRTUAL 3D RESTORATION OF AN EXTINCT VILLAGE AND ITS EYE-TRACKING ASSESSMENT

The objective of the project was to create 3D visualization of an extinct village and its evaluation using eye-tracking. As an area of interest, the extinct village of Čistá was selected. The village was located in Karlovy Vary Region in the Czech Republic and was destroyed in 1948. The village was destroyed to primarily to establish a military training area. Secondly, it was destroyed to create an instructional video for military purposes called “Fight in the settlement”. During the creation of this video, the village was destroyed. The main content of the project was to create an interactive web application that includes a 3D model of the extinct village of Čistá. As base data, aerial photos made in 1947 and stable cadastre from 1841 were used. Buildings were made according to historical photographs and screen shots from the instructional video “Fight in a settlement.” The resulting 3D model and underlying data were loaded into Google Earth API and are available for the general public now. The second part of the project was to test the model usability using eye-tracking. In total, 28 respondents participated in the experiment. The experiment contained two parts – the overall views of the village and tasks, where users were searching for a particular building. Recorded eye-tracking data were statistically and graphically analyzed. The results indicate that a 3D model was the most usable type of visualization for respondents. A link to the application was placed on the web site of the project of an educational trail about extinct villages in the Slavkov Forest area. The created 3D model and application present the extinct village of Čistá to potential visitors of the educational trail.
