Ubiquitous Body: Effect of Spatial Arrangement of Task's View on Managing Multiple Tasks

This research proposes a concept of the "ubiquitous body system", a new concept of using multiple body parts at various places simultaneously. This system enables users to access any number of the bodies at a time, and make physical intervention to any locations regardless of the current location where user's natural body is. However, when the number of ubiquitous bodies becomes larger, it becomes more difficult to see or manage all of those tasks. In this short paper, we focused on the effect of spatial arrangement of the vision information on managing multiple tasks. We developed a vision presenting system in which the environment images of each ubiquitous body are arranged in the same way as the positional relationships of ubiquitous bodies in the real world. The result of a case study regarding usability of this prototype suggested that presenting visual information with same spatial relationships as real would be effective to switch user's attention and manage multiple tasks.
