Abstract

Projecting midair projections in a 3D space for multiple users, such that the midair projection is not an obstacle to users within the 3D space. The restricted area in which the midair projection should not be displayed is determined by identifying users which are having face to face interactions and an associated level of interactions of the identified users. Then the focus areas of the identified users and attention level of the identified users on the focus areas are determined and the focus areas of the identified users are aggregated to restrict midair projections from the aggregated focus areas of the identified users and designated area not in the aggregated focus cones as content allowed areas where content can be projected in midair without disturbing other identified users.
