Publication: Comparing Content and Input Redirection in MDEs

Designers of Multi-Display Environments (MDEs) often use input redirection to allow users to manipulate content on multiple displays with a single interaction device, but users seated at sub-optimal positions (i.e., not facing the display) may find interaction difficult or frustrating. In collaborative MDEs, users should be able to choose their preferred collaborative arrangement, rather than adjusting to the limitations of the technology. We compare content and input redirection from a variety of seating positions in an MDE. Results from our studies show that content redirection does not suffer from performance loss in sub-optimal seating positions, as opposed to input redirection, which does. Content redirection provides a method for all members of a group to interact with shared content regardless of their position relative to a shared display.

Advanced Interaction for Multi-display Environments
Multi-display environments (interfaces composed by several display surfaces) have the potential to dramatically change the way that we work with digital information: for example, they provide a variety of work surfaces to fit different kinds of tasks, they provide a very large visual bandwidth, they enable the use of peripheral attention space, and they naturally support co-located collaboration.
