Situation analysis at a digital situation table with Fovea-Tablett

A digital situation table which allows a team of experts to cooperatively analyze a situation has been developed. It is based on a horizontal work table providing a general overview of the situation. Tablet PCs referenced precisely to the scene image using a digital image processing algorithm display a detailed view of a local area of the image. In this way a see-through effect providing high local resolution at the position of the tablet PC is established. Additional information not fitting the bird's eye view of the work table can be displayed on a vertical screen. All output devices can be controlled using tablet PCs where each team member has his own tablet PC. An interaction paradigm has been developed allowing each team member to interact with a high degree of freedom and ensuring cooperative teamwork.
