15. Collaboration | TelePresence • Being Here is Being There • As convergence brings voice, data, and video onto the same network. • Business discussions will encompass not just multiple people but also multiple locations. • In the past, videoconferences in particular have been difficult to set up, challenging to use, and frequently unsatisfying in their ability to replicate in-person meetings and the benefits of face-to-face interaction. TelePresence delivers real-time, face-to-face interactions between people and places in their work and personal lives using advanced visual, audio, and collaboration technologies. These technologies transmit life-size, high-definition images and spatial discrete audio.
