Abstract

Tabletops are large interactive displays that enable users to interact for collaborative analysis and planning on datasets. These devices allow communication using pointing and gestures and interactive zooming, searching, and modifying data. However, when interacting with large maps, the user must analyze details that can only be viewed by enlarging the map region. Furthermore, it is interesting to visualize the context (zoom out) and the details of a specific area (zoom in). Magnifying lenses are often used for this purpose, but these lenses have the disadvantage of losing context. In this paper, we present a new technique for interaction using magnifying lenses for tabletops to improve interaction usability in large maps. We analyzed several techniques discussed in the literature for magnifying lenses. We performed experimental implementations in the context of the SIS-ASTROS GMF Project. We validated the work through objective and subjective analyses, and the results demonstrated significant improvements in objective metrics, such as time and accuracy, as well as in subjective metrics, including frustration, effort, and mental demand. The NASA-TLX Questionnaire was used to evaluate the subjective metrics.
