Abstract
A system enabling participants in a virtual environment to select a partner for an interaction session, the system comprising attention and priority components. The attention component employs attention sense and focus spaces. The sense space comprises a sense cone, the sense cone being both contained by a sense sphere and having a sense vector along its axis. The focus space comprises a focus cone, the focus cone being both contained by a focus sphere and having a focus vector along its axis. The attention component is associated with one or more senses, each such sense having associated therewith respective sense and focus spaces. The attention component is configured to support either/both intentional interaction (interaction driven by defined explicit controls) and spontaneous interaction (interaction driven by non-intentional encounters, e.g., spontaneous “eye” contact between avatars). The priority component determines priorities for avatars and objects, such that highest priority avatars/objects have (a) enhanced rendering and (b) increased quality of service from networks and operating systems. The priority component is responsive to selected parameters, includi…
