55 percent of experts say people will routinely interact in artificial spaces through virtual worlds and other types of "augmented reality." "Most well-equipped Internet users will spend some part of their waking hours -- at work and at play -- at least partially linked to augmentations of the real world or alternate worlds," Pew states. "This lifestyle involves seamless transitions between artificial reality, virtual reality, and the status formerly known as 'real life.'"
Voice-activation and touch will be common technology interfaces by 2020, according to nearly two-thirds of experts.
