Sharing one's own immersive experience over the Internet is one of the ultimate goals of telepresence technology. In this paper, we present JackIn Head, a visual telepresence system featuring an omnidirectional wearable camera with image motion stabilization. Spherical omnidirectional video footage taken around the head of a local user is stabilized and then broadcast to others, allowing remote users to explore the immersive visual environment independently of the local user's head direction. We describe the system design of JackIn Head and report the evaluation results of real-time image stabilization and alleviation of cybersickness. Then, through an exploratory observation study, we investigate how individuals can remotely interact, communicate with, and assist each other with our system. We report our observation and analysis of inter-personal communication, demonstrating the effectiveness of our system in augmenting remote collaboration.

Sharing an immersive experience enhances situational awareness, enabling effective collaboration between persons in different places. The development of a head-worn camera enables us to capture the first-person view and share it as the personal experience. However, the limited viewing angle of such cameras prevents a remote viewer from obtaining a complete surrounding situation. In this paper, we propose a system called LiveSphere, which presents the entire surrounding visual environment using a head-worn system with multiple cameras. The image-stabilizing algorithm compensates image motion caused by the wearer's head movement. This enables the remote viewer to look around the environment independently from the wearer's head direction. We developed a prototype to examine how sharing the surrounding visual environment improves collaboration between persons in different places.
