Paper Abstract:
|
This dissertation presents audio windowing systems for visualization, attention, and privacy awareness of narrowcasting (selection) functions in collaborative virtual environments (CVEs): for a workstation WIMP (windows/icon/menu/ pointer) GUI (graphical user interface), and for networked mobile devices, 2.5- and 3rd-generation mobile phones. These interfaces can be used to control source→sink transmissions in synchronous groupware (like teleconferences, chatspaces, virtual concerts, etc.). The interfaces are integrated with other CVE clients, interoperating with a heterogeneous multimodal groupware suite, including stereographic panoramic browsers, spatial audio backends, rotary motion platforms, and driving simulators. The narrowcasting operations comprise an idiom for selective attention, presence, and privacy an infrastructure for rich conferencing capability. The platform-agnostic deployment of audio narrowcasting operations encourages the modernization of office- and mobile-based conferencing, leveraging session integration across coextensive spaces and anticipating multipresence enabled by higher bandwidth and more durable mobile connectivity. |
