Publication: E-conic: a Perspective-corrected Interface for Multi-display Environments

Multi-display environments compose displays that can be at different locations from and different angles to the user; as a result, it can become very difficult to manage windows, read text, and manipulate objects. We investigate the idea of perspective as a way to solve these problems in multidisplay environments. We first identify basic display and control factors that are affected by perspective, such as visibility, fracture, and sharing. We then present the design and implementation of E-conic, a multi-display multi-user environment that uses location data about displays and users to dynamically correct perspective. We carried out a controlled experiment to test the benefits of perspective correction in basic interaction tasks like targeting, steering, aligning, pattern-matching and reading. Our results show that perspective correction significantly and substantially improves user performance in all these tasks.

Projects

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.
