 throughout the day. Soon, you will have a single identity that spans all the ways people can reach you, and you will move a conversation seamlessly between voice, text, and video and from one device to another as your location and information-sharing needs change. Longer-Term Technological Changes To realize many of the goals for UC, three major areas need to change: Immersive experiences outside of controlled environments Ability to connect to experiences across a wide variety of devices at different fidelities The capability to initiate connections between any device with a pervasive methodol- ogy to connect Each of these three areas will have a dramatic effect on the future of communications. The year 2050 can be assumed as a reasonable proxy for "Longer Term," and as such, is used here as a date proxy to describe how UC experiences will occur in the longer term. Table 13-1 outlines the impact, possible timeline, and technology advancements required for these changes.
