Lifelogging meets alternate and cross-realities: an investigation into broadcasting personal visual realities to remote audiences

We address in this work the topic of broadcasting one’s visual reality, captured by the video cameras embedded in mobile and wearable devices, to a remote audience. We discuss several designs of such life broadcasting systems, which we position at the intersection of lifelogging, Alternate Reality, and Cross-Reality technology. To this end, we introduce the “Alternate Reality Broadcast-Time” matrix for the broadcasting and consumption of alternate realities, in which designs of systems that implement sharing and consumption of personal visual realities can be positioned, characterized, and compared. These design options range from simple video streaming over the web using conventional video protocols to mediated and augmented reality, to audio narration and vibrotactile rendering of concepts automatically detected from video captured by wearable cameras. To demonstrate the usefulness of our broadcast-time matrix, we describe three prototypes implementing lifelogging, concept recognition from video, augmented and mediated vision, and vibrotactile feedback. Our contributions open the way toward new applications that blend lifelogging, consumption of multimedia alternate realities, and XR technology to empower users with richer opportunities for self-expression and new means to connect with the followers of events in their lives.
